0 # Bulk LPG ConversionLizz 2017-02-22 20:25
How do I convert cubic feet into litres for bulk LPG, is it roughly divide by 9.66? So, my metre says 10(00) cu ft = 103.52 litres? Multiply that by 58.5p per lite (I find that excessive but landlord resells it to us via the rental agent, so I guess I have no choice). Are there any rules protecting tenants against overcharging that you know of? I can only find help and guidance for "authorized suppliers" and I do not think bulk LPG comes under that Ofgem ruling. Any help you can give would be appreciated. :-*

Your calculations are correct. Your landlord is making a margin on the resale of the LPG. I wonder if VAT is applied twice? I guess he or she is buying at a good bulk rate and selling to to you at 30 to 40% more. Problem is the landlord I guess has the buying power for the fuel and rents the storage for the fuel. I am unaware of consumer protection on this I will dig around to see if this has changed, the question is asked quite often. Give me a few days. Cheers Richard

Hi there,

I stumbled across your site trying to find out what was more effective: Boiling a kettle for 2 cups of water or using a gas stove for the same volume. Still don't have the answer! However, I found your site interesting but confusing at points.

I have experience in delivering research and insight to clients within a consumer research environment and would happily provide feedback to your site. This consumer information should be made available to the market and you are clearly looking at everything in depth, all be it a little confusing to the average joe at times.

Please email me if you'd like to discuss this further.

This page ... says the cost of bulk LPG is 4.5p per kwh, but it is actually over 7p per kwh. It also says that oil is cheaper than mains gas. These figures are definitely wrong.

The values for energy on the whole site are averages over the year and oil was cheaper. It is going up now owing to winter demand and poor Brexit induced $ exchange rates, I would imagine OPEC limiting supply will have an effect also. LPG and OIL are more expensive in the winter generally.

Hi, my mother is private renting and her reading from 16/10/16 - 02/12/16 was 47 units. What would the average bill be for this for a 2 bed lodge with calor mains gas. As she has been told by her landlord to pay £180.95.

First how is the unit defined, is it a kWh, a cubic meter , a litre? What does it say on the bill. second are there any other charges on the bill like tank or cylinder rental etc.

Is she using LPG for heating? I assume she is. If she is she could have used 1000 to 1500 kWh as an estimate.

there is roughly 27kWh to a cubic meter, so if the unit is a cubic meter then 27 x 45 gives 1215 kWh, which is a sensible number for the period concerned.

but it does mean she is being charged 15p per kWh which is high, but there may be standing charges.

We have Economy 7 storage heaters and electrical water heating. We have no gas but are thinking of having a supply connected. Could you give us a ball-park running cost figure if we installed gas central heating in our 3-bed semi-detached house? We currently have 4x storage heaters and would need them replaced by 7x central heating radiators. We think it would be cheaper that the current set-up and are trying to work out the pay-back period for the cost of installation.

I have a home along with 12 others on a new development where we have an underground LPG tank. I believe this is called a metered estate. We are supplied by Calor. When we all first moved in we were charge 49p per litre because that's the deal the developer put in place. Soon after I negotiated this down to 38p. This still seems very high. Are you able to tell me what the average charges are for a similar estate, please?

Hi Lynne
I do not have that data. LPG is by far the hardest fuel to get data on, because it is very regional and storage need to be considered etc. However 38p a litre does not seem too bad it is about 15% more than the figure in this site, this could be a regional fluctuation. Are you including tax in your number?


If anyone else who uses the site has a metered estate price for LPG can they reply to this post perhaps we could get some data.

The average price for LPG at the moment is 30ppl. It depends on usage and whereabouts you live. The cheapest I have seen is 27.5ppl. It is sometimes difficult to make comparisons as some suppliers also rent the tanks and usually supplies are on long term contracts. Some suppliers also make special offers ( such as a free amount of LPG) to entice people to switch suppliers when they are at the end of their contact.

I am hoping to build a 5 bedroom detached house in Yorkshire probably with one or two ensuite bathrooms and one family bathroom.I asked the electricity company to ask their advisor to call.Evidently we are at the end of the main electric line and size of supply could be a problem.He advised gas central heating and one electric shower,he said a 14KW supply would be OK. Does the number of showers matter I should have thought that the gas boiler would have heated the water, with the electric motor on the boiler which would give power to the shower from the pump that drives the central heating providing the power.
Would it be better if we had a gas cooker and I understand there are gas washers and driers available.We should need an electric kettle,and lights,Is there legislation on using low power lights.How do they arrive at 14KW do they assume that all the lights and other appliances are on at the same time is this 14KW per hour.What other electric appliances can you think of that we should have to have in the house could I specify the fact that I was using gas as much as possible or would they not take this into consideration.I am 75 and find it all very confusing,I suppose the kitchen lights would have to come on immediately.If you could respond asap I should be gratefull,why would he specify only one electric shower,and why not use the gas boiler for power for the showers ,why have any electric showers at all,I can appreciate that gravity feed would not be suitable.

Many thanks,

Hi John,

If I’m reading your comment correctly, An electric shower requires about 10kW so if two were on at the same time that would exceed the 14kW they recommend if you do not want the voltage to drop which could affect things like the TVs as well as the lights dimming. I guess in a 5 bedroom house in the morning this might well happen.

I doubt whether many other electric devices in the house will take a continuous high power although I guess the cooker, washing machine and dryer take a fairly high power. Washing machines and dryers use 13A supply which means they are always less than 3kW while an electric shower is up to 50A. Cookers typically use a 30A supply but then everything would be on, all hobs and the oven! Lights do not take much power and it does mean kW and not kW per hour. I do not know of any regulations about lights except for them stopping the production of certain bulbs.

N.B. A kW is a measure of power (the speed at which energy is delivered)
A kWh is a measure of energy (how much energy is used.)

0 # Excessive electricity usagePetrus 2015-11-02 00:17

I've been trying to find out the cost for using a 100W lamp for about 54 hours. We're using E.on and I think the cost for electricity is 14.417p/KwH or at least was the last time I checked a few months ago.

I'm not sure how to count that and thought I could ask you for help and maybe even an explanation how to count it.

Your sincerely
Reply | Reply with quote | Quote
0 # replyrdh 2015-11-02 10:41
Hi Petrus
the power of the lamp is 100 Watts (100W)
the time it is on for is 54 hours
multiply 100 by 54 = 5400 Watt hours
divide by 1000 to get the units into kWh (kilowatt hours)
so this is 5.4 kWh

it costs 14.417 pence/kWh

5.4 kWh x 14.417 pence/kWh = 77.85 pence

notice how the kWh units cancel each other ourt to leave an answer in pence. this is a good chech to show you have the maths correct.

Thank you very much Richard.

So I don't really have to worry about my flatmate keeping the light on for long periods in her room/the hallway without actually being there, then? I have for 9 months tried to keep track on her excessive electricity use to talk to her about it and the importance of saving money by not having the light turned on without a good reason. But if the cost of excessive electricity use for 54 hours (during a period of nine months) is around 80 pence, which sounds a bit too little to me, she can carry on keeping the light on for how long as she like, then.

If the light bulbs don't require much electricity I wonder what has cause us to have to recharge the prepay-meter with money so often?

Having a roof done on a 30's semi-detached. Upgrading the loft insulation. I haven't found any advice about the trade-off between adding loft insulation and arguments about consequent vapour condensation. Suppose I upgrade from 100mm to say 270mm, and simultaneously add some ventilation. Have we made a relative gain or loss? My roofers opinion is to just not overdo the insulation - no ventilation. I suppose is a conduction vs convection argument.

Anyone done any test data on two similar loft spaces I wondered - we all have a roof.

molar mass of propane is 0.044kg/mol
47kg per cylinder
47/0.044 = 1068 mols

One mole of an idea gas occupies about 0.24 cubic meters at Room Temperature

So the volune of gas that should be delivered from the cylinder is
0.24 x 1068 = 25.6 cubic meters

To most of the English speaking world a mole is small burrowing animal the makes a mess of the lawn. To a scientist a mole is also 6 x 10 raised to power 23 atoms or molecules.

This is the link:-

We tend to do updates only once a year in March as the price fluctuations over the year tend to be more noise than a trend average. We can do an update in late September if that is useful to you, We have a bit of time then.

this is good for oil, please note the seasonal fluctuation on the graph.

0 # Effective price (pence) per kWh of delivered energyKaty Collister 2014-07-04 10:23
Please can you confirm (with a short example) the forumla used to calculate the cost per useful KWh as your figures do not stack up with ours. If a boiler is 50% efficient for example, 50% of the input will be converted into heat and 50% will be wasted as by-products. Therefore, a 50% efficient boiler should cost twice the cost to run as a 100% efficienct boiler in which nothing is wasted? Your figures do not show this to be the case and I'm unsure how you are working out the end price.

Thanks in advance

0 # Electric vs Power ShowerJackie 2014-05-15 22:46
Hi, I had a solar PV system fitted Dec 2014 and more recently, an Optimmersion which provides ample hot water in summer. In the winter my water is heated by an old oil fed Parkray conversion which doesn't always get the water tank super hot. With three of us using the shower every day we will probably have to use the 1hr boost button on the optimmersion once (maybe twice) a day.

Is it possible to know which type of shower would be most cost effective to run - Electric (8.5kw) which will be powered by the grid and solar energy in summer, and mostly by the grid in winter...or...a Power shower which will have water heated by solar energy but will require boosting in winter. This doesn't even take night time showers into consideration.

I may have just answered my own question, but if you could give my your opinion on this I would appreciate some feedback.

Hi Jackie

Your question invites hundred of other questions. And their is no full answer. There are too many variables.

The bigger picture questions are

Are you on a FIT contract.
How much did solar PV and the hot water system cost you.
How much standard energy could you have bought with money and the interest which could have accrued on the defrayed expense for the renewable energy systems.

lets ignore the above question and assume all is paid for and that this is the starting point, this is more likely what you want to know.

The power shower, is heated by oil, it will cost 50% more than that heated by gas. have a nosy at this:- ....

Reference to the table in the link you will see that the electric shower comes out cheaper because the amount of water being heated is less than with a power shower even though electricity is more expensive.

As a rough guess I would say the power shower on oil is twice as expensive as the 8.5kW shower to operate when considering only grid electricity.

So this should answer the question the electric shower on cost grounds wins in the winter. But its not as nice!

0 # High bill for gasEva 2014-02-27 15:33
Hi there,
I'am looking for some help, I've just got my second bill for gas in my first flat which I'm renting with friends and we are wondering why we have to pay so much?
Our gas provider is Brithish Gas and we are using standard tariff.
Our first bill for period from 14 sept to 14 nov was 136.75pounds and we used 2599.03 kWh.
Now we got a bill for period from 14 nov to 22 feb which is 304pounds with usage 5594.69 kWh.
We are renting house with 4 bedrooms its 2flours house and we have another flat under our part. To be honest this is just heating usage cos cook and shower are using electrisity and what is more we have heating on max twice a day (if its not off in warm days) for 2 hours in the morning and 5 hours in the night with temp around 20 degree. Problem is for more than 3 weeks during christmas period we were as a students even not there so we turned heating off. Is that possible to use that much? Cos we are afraid that maybe somehow we are connected with flat under us (which seems stupid but well) or our meter is not working properly especially that when we checked on British Gas page the average quarter bill for our area is around 180pounds.
I will be very gratefull if you can share with us your opinion about it cos we dont know what to do now.
Thanks in advanced

Hi Eva, I think this is normal. The rate you are paying is about correct but you could switch to reduce this. The amount of energy is also correct. The average you quote from British gas is also correct, Remember that that average will include summer, when you will switch your heating off and use no gas. A four bed house for heating and hot water can easily use 15000kWh a year. As rented accommodation I bet you have little or no loft insulation, this can make a very large difference, if you landlord is approachable ask, most however are not!

0 # gas central heatingrebecca 2013-02-12 12:41
Hi there, I stumbled across this website, as I was confused about why my gas bill has risen considerably, since British Gas installed a pre-payment meter. From an average of 55kW/h per day for using the shower for 40 mins and the central heating for around 10 hours per day in the winter months - I am now using 98kW/h for the shower for 5 mins, and the central heating for no more than 5 hours per day. (Plus I am on the same 2 tier tariff as I was on the credit meter, with 'no' standing charges), so I cannot understand why the kW/h are so much!As you can see, this is a considerate rise in kW/h since the installation of the prepayment meter. British Gas say this is normal, because an average household pays at least £1.30 for central heating per hour - although I find this hard to believe, as my gas bills were far less than this when I had a credit meter. It appears that the new meter maybe ticking over too quick? (However, British Gas don't believe this is the case). When the central heating is on for 1 hour, 19.25kW/h is being used - does this look right to you? (Does a gas boiler really use this much energy?) Would really appreciate your advice, because I wonder if other people are also suffering the same problem.Kind regardsRebecca

Hi Rebecca

It is very difficult to see what is going on here. Was it generally warmer outside before the change in meter?

Heati ng is much more significant than the water so lets concentrate there.

The British Gas value of £1.30 per hour is completely meaningless. Do they mean on average or when the heating is on and at full power output. It must be the latter or you bill would be £11000 a year.

[N.B. £1.30 an hour implies a gas boiler operating at about 30kW]

Just for info, having the heating on for 10 hours and then 5 hours is not linear with energy use. By this I mean that you may have had the heating on for 10 hour before but the thermostat will have switched it off periodically., with it on for 5 hours it is probably on at full power all the time.

The maximum power output of your boiler is likely to be capable of is 30kW, so 19.25 kWh is almost certainly correct and reasonable.

[N.B. the measure of energy is kWh and not kW/h, pedantic pain in the neck that I am! This is power 19.25 kW multiplied by the number of hours it is on. So if you had measured the energy use for two hours it would have been 19.25kW x 2 hours = 38.5kWh of energy used]

The difference is a mystery, The only conclusion I can come up with is that it was warmer outside before, when did you have it changed?

Hi Richard,

Tha nks for the quick response.

No , the meter was changed at the beginning of February this year, and it is averaging almost 9 cubic meters per 24 hour period, so I think that works out to around 99kWh per day?

The old meter (in the winter periods, and in the same period last year), averaged no more than 55kWh per 24 hour period, so there appears to be some problem here, but I can't think what it could be, apart from the fact - the meter is ticking over too fast?

Also we are using less energy than we did when utilising the old credit meter, and we are now in the cold most of the time, because of the high bills. British Gas are insisting the new meter is running at the correct rate, however; as can be seen - clearly it is not.

Have you ever heard of anyone suffering from such problems with British Gas? I have even received the previous bill from Nov 2012 to Jan 2013, (before the credit meter was changed). This bill shows an average of 54.93kWh per day - so I can't for the life of me think why the pre-payment is averaging 99kWh. (Plus with the old meter, we used more gas than we do now).

Would really like some advice, as we have children, and are in the cold most of the time.

Kind regards

0 # gas central heating billsRichard 2013-02-14 18:07
Hi Rebecca
More Questions I’m afraid. With my credit meter I pay by direct debit with my meter being read occasionally. The amount I pay each month is the same and is based on my predicted annual use. Annually we use about 20,000 kWh which approximates to 55kWh each day, It is an average sized house, reasonably insulated and in the North of England. In the summer, use is probably less than 10kWh a day and in the winter it is probably 150 kWh or more. Today I was feeling like a wimp so it has been on all day!

If before the meter changed you paid by direct debit then it is likely that you were paying an averaged amount which had little correlation to actual use in the given month.

If you paid quarterly and the meter reading were actually taken for the bill period you then clearly know how much gas you used over a given period. If they used estimates they could have underestimated actual use prior to change.

Thes e questions sound a bit patronizing, but I’m just trying to work out the problem before suggesting that you get your meter checked. By the way you do have the right to ask for this. Have a look at this link

0 # pre-payment meter (gas central heating)rebecca 2013-03-29 10:20
Hi Richard, Thanks for trying to help with this issue, but unfortunately, it's still on-going. Haven't been on for a while, however, in the meantime, I've gone through all of my previous bills since 2010 (requested this through Data Protection), and have drawn on information from the kWh used.

I can see that, on average; my old credit meter used between 4 - 5 kWh for heating (per hour), whether in spring / autumn or winter. My new pre-payment meter is showing 17 - 18kWh per hour for heating usage. There is no room thermostat, only a thermostatic control on the combi boiler, which has always been turned to 'just under' half way.

We only use the gas for heating. All other appliances in the home (ie.cooker), are all electrical, so I know this hasn't been the cause of the rise in kWhs.

Also, just before the installation of the pre-payment meter in February this year, my old credit meter still showed an average of 4 - 5kWh per hour of energy usage when the heating was switched on.

British Gas have come an re-set the pre-payment meter, however, it is still reading the same way. They said they will not call another engineer out to the property, as we are still able to obtain gas, so unless it is cut-off in some way; it does not matter how much the kWh appear to be, we will have to pay for what we use.

The Complaints Team at BG have also been SO KIND to advise; "Don't use your gas too much, if you can cut down on your 2 hours per day usage for heating, then this would benefit you if you cannot make the payments." ("Of course British Gas, this won't be a problem for me; it is ONLY between 0 degrees to 5 degrees outside!")

A t the moment, 2 hours of gas usage has cost me almost £4, and I have a vulnerable child in the house who suffers from asthma and chest infections - and British Gas know of this already, and have 'not' placed her on the Vulnerable Customer Policy they signed up to with the Energy Retail Association.

I am thinking of taking the matter to the Ombudsman, however; without a Final Deadlock letter (which despite numerous complaints via letters to them, BG are not willing to give me); the Energy Ombudsman will not handle this.

Failin g which, I may need to take them to Court, but once again, this will cost me 'my' time and money.

Don't know what else to do?

Look forward to your response.

Ki nd regards

0 # Condensing boilersHoward 2013-02-03 16:03
I have an old open flue 30kW gas bolier bought 25 years ago in a bankruptcy sale. it has been entirely trouble free apart from one new pilot light sensor - about £6 at the time.

If and when this boiler fails beyond repair I shall be forced to replace it with a condensing unit which will mean relocation and new flue arrangements. This is likely to cost around £3000 + with labour.
Althou gh the the new boiler would be more efficient and make less CO2, I don't expect to get the same service life due to much greater complexity, electronics and complex materials. In fact i believe the repair/ replacement cost of the condensing unit will be more than the gas cost savings.
Why have we been forced into this situation?

Night Storeage heaters
1 Monday, 07 January 2013 20:45
Tim Heaps
I have inherited a 25 year old 3 bedroom bungalow that has 5 night storeage heaters, an open fire place 3 electric wall heaters (rarely used) in the bedrooms. The building has been well insulated and there is a porch covering front and back doors. There is no main gas available. Total energy bills are around £85 per month on average over the year.

Should I replace the storeage heaters with new versions and replaced the open fire with a log burner (very rural location with plenty of wood freely available)

in terms of efficiency I would not imagine the new versions of storage heaters are much better, But I do not know for a fact, I would imagine that it is not a great investment. Regarding a wood burner, a proper stove can be very efficient , more so than an open fire so this may be worth doing.

Why do we have to pay 5 times the price for the same kW of electricity than we do for that of

It makes no sense at all. Currently, the wholesale price of gas is 65 pence a Therm (29.3 kW).

This equates to a unit price of 2.2 pence for Natural Gas?

Electri city costs 11.25 pence a kW. Both these figures exclude the standing charge.

0 # pricesRichard 2013-01-09 17:22
your unit prices are not correct, but the question you ask is why is electricity per unit of delivered energy much more expensive. The answer is quite simple. with gas and almost all fuels you burn in the house the process of converting the fuel to heat energy is very efficient 90% + with a modern boilers.

Wit h electricity generation fuels like coal or gas are also burned . These are burned in the power station and used to power a turbine with steam which in turn generates electricity, this process is very inefficient, about 30%. So given that electricity providers have to burn the same fuels we use in our homes electricity is about 3 times more expensive , because of the inefficiency of converting the energy in the fuel into electricity.

0 # Insulation and heating of a conservatoryHeidi 2012-10-31 14:51
Please can you help? We recently bought a 17th century cottage with a new conservatory. The conservatory is completely open to the house and is used on a daily basis as a living room. It has a polycarbonate roof, tiled floor and no heating. We are planning on having a cedar shingle roof fitted over the existing roof to include insulation between the two and are also fitting an engineered wooden floor as the existing tiled floor is very cold. We currently use an electric radiator with fan booster to heat the area when necessary. The windows have wooden slated blinds that can be closed at night to help insulate the room. Is there anything else we can do to reduce the heat loss from this space and what would you say is the most efficient way to heat it - a radiator attatched to the oil central heating system or underfloor heating? We have also considered having a wood burning stove fitted as we already have a spare one although the fitting costs have been on average quoted as £2000.

Sounds nice.

This is a common problem and I have been racking the brain for simple solutions for years. In my own house I have made my own insulated slide in panels for the inside of conservatory roof, but your solution sounds better, but more expensive.

W ith regard to the floor, can you put some insulation under the engineered wooden floor?

Under floor heating in this instance would be electrical, and would be very expensive to operate, but nice on the feet.

A radiator on an internal wall would be the cheapest option to fit and reasonably priced to operate.

The stove might actually be cheaper to operate given the cost of oil, but it would certainly be more hassle, but nice I guess if you have the time.

The only other comment from my own experience is heavy curtains with an insulating fabric liner (do a google) make quite a lot of difference.

I'm contacting you on behalf of GenFit, a renewable energy provider who are a cient of mine. Dave Houston (founder and owner of GenFit) has written extensively about the Feed in Tariff changes as well as the Renewable Heat Incentive and the implications (of both) for domestic installation of renewable energy systems. He has also created a table of ROI for solar pv which gives a rough idea of time frames of return on investment for solar pv with the recent changes to the feed in tariff for the average household. Let me know what you think of the table ( Additionally, Dave has written several editorial pieces on the changes which I would happily send across if you were interested in a guest-post from an industry expert.

I look forward to hearing from you either way.

Hi Arthur The numbers in the table stack up given the installation cost figure of £8500 for 4kWp (inc or ex VAT? 5% I think). If the fuel prices include VAT it is only fair to add them to the capital cost. I would like to see the editorial pieces, and am very happy to add a guest post, provided it is factually based. I will e-mail you. cheers Richard

Question about the Energy Information on your website

De ar Editor,

I have recently visited your site and wanted to get in touch as i work for the website and was hoping to speak about the information you are currently showing.

Our team has spent the last 3 months creating some excellent free Energy widgets and after looking at your content and style our designers think they would be a great fit for you.

(There is no charge for using them and at present there is nothing else like them available.)

The free widgets cover Crude Oil, Natural Gas, Coal, Solar Energy, Wind, Nuclear, Geothermal and all other energy sub sectors. We also have many other widgets that may be of interest which cover gold, silver and other financial data.

All widgets are interactive and are constantly moving – which adds to their interest and value to visitors. They are superbly designed and the data provided would normally be very difficult to obtain and especially difficult to package into meaningful charts and graphs.

To see what we have please take a look at:

The widgets focus on:

Worldwid e energy consumption (by country – figures updated every second)
Worldw ide energy production (Crude oil, coal, natural gas, solar, Nuclear, updated every second.)
Alter native energy production (by method: Solar, wind, hydro, etc..)
Crude oil clocks
Greenho use gas counters
Oil & Gas news
Gold holdings by country (US, China, UK, Switzerland. Constantly updated and moving.
+ Many more...

Inst allation is incredibly easy as you just take the code by the side of the widget and paste it into your site. There is also an installation guide to the right of the screen.

Oilp has also created a discussion forum for like-minded energy professionals, news followers, investors & traders to gather and discuss all things energy. Whether it be crude oil prices, the latest solar energy developments, wind power, nuclear fusion, global warming, trading ideas, geopolitics + many other topics.

You can find the forum at the following link:

We hope you get a chance to look at what we have available as the data is very engaging and if you do choose to display it on your site, we are certain it will encourage visitors to return again and again.

If we can be of any further service to you please do get in touch.

Help! My Electricity usage according to EDF seems to have rocketed and they estimate that our annual consumption will be over 8,000 kw at a cost exceeding £1,000 annually. I have oil heating (approx £650 pa) We are a family of 4 (2 teenage kids) living in a modest bungalow (working /school) and I cannot appreciate how we could be using so much. Is it possible that the meter is faulty? Standing charge 14p per day and units = 12.49p. Any responses greatly appreciated!!

0 # EDF & THE FRENCH WAY OF CALCULATING YOUR BILLSMark Cooper 2013-01-01 08:33
Andy, I too am with EDF energy (French Owned) and disbelieve the way they calculate my energy use. We are on the fixed 2014 tariff, which sounds good, as prices have risen. However, despite giving actual consumption figures at the beginning of the contract, which fixed our use at 13393 kw for gas and 3330 kw for electric, at a quoted price for both per annum of 980 gbp, what they acually have done, instead of taking 80 gbp per month by direct debit, they OVERESTIMATE our consumption and in one month the took 145 gbp by direct debit, or any amount they choose. This is not what we agreed, but this allows EDF to rape our account, to ensure a Credit Balance in their favour - now estimated to give the big six energy cartels ove 2 Billion free money. I cannot get them to agree to take 80 gbp/month as agreed, so now I read the meters monthly on around the 17th of the month, and submit on line to make it difficult as possible for them to cheat me further, and ask for a refund of overcharged unit, which they do, reluctantly. I know this is a pain, but I no longer trust the energy giants or their computer models. I had a similar experience with Npower and British Gas. so switched to EDF of a clever sales pitch, by their agent (who incidentally received 50 pounds for selling me the contract). We pay for this in our bills. One last thing, a question no one can get an answer to is, Why do we pay 5 times the unit price for electricity compared with that of gas. The wholesale price per uniit of gas is approx 2.2 pence, electricity is 12 pence. Why is this. Look at the profits of the big 6, 6 Billion pounds a year, and the National Grid 2.7 Billion, with the government tax taking 5%. I maintain that consumers have not benefited from deregulation of the UK energy industry as all prices when compared are almost the same. We (2 of us) are pensioners in a detached 3 bed house and are in fuel poverty where more than 10% of our income is taken up with energy!! The whole industry is fixed by foreign multinationals who care nothing for their customers, so expect continued rises in energy, because they expect you are I to pay for their future capital equipment expenditure! Happy New Year - Keep a weather eye on these sharks. Mark

Can you give the forulae for calculation the price of energy from comparative sources. eg On peak, off peak electricity , 28 sec oil

I imagine something like this

Cost per unit x energy per unit x efficiency of apparaatus x energy in each unit. = True comparative cost ( that can be varied by the user as energy prices vary )

I am very pleased to find your website after much searching for info on cooker energy usage
My daughter wants to set up a small business and wanted to put the cost of using the oven so many hours a week a certain temperatures into her business plan.
Your cooker page is very helpful but gives less specific information.
Y ou base your estimate of cost on Cost per use @ current prices - could you please clarify what you mean by "per use"? Presumably this is an average length of time an oven is used - for example 30m.
Our range is B rated apparently - with one small and one larger oven.
Could you give an indication of how many Kwh it would use at different temperatures per hour?
How could I find out this information?
I am really hoping you can help us with this

Hi, I have enjoyed reading this site and found the info really helpful. I have a quick question and am not sure where it was best posted.
We are currently staying on a camp site in an American RV whilst we are buying a house. The owner of the site has just informed us that he is charging electricity as an additional cost starting from this month. He will not disclose who the energy supplier is(I presume he has business rates) and has not yet advised how much per unit he will be charging. We have heard on the grapevine that it will be 20p per unit, plus 14 pence per day, plus 1% (have no idea what this is for),plus vat...
Can he do this legally and who would we take advice from if not? Over 3 days with hardly any electricity use we have used 40 units according to his meter. This could cost us in a month close to what a house owner would pay a quarter. Any help or advice greatly appreciated. thanks

He sounds like Mr Fiddler from Carry on Camping. looks like 80 to 90 quid a month. Most camp sites charge for a hook up, but I guess this was included before in the total price. I think he probably can do this, he is basically charging a margin on the electricity that is supplied to him, and would argue that it pays for the infrastructure he has had to install. It does however seem very expensive.

4 0 units seem high also, if you do not think you have used it much. you could get a device to measure how much you are using to check his meter.

To get advice I would go to trading standards, they are usually very good. Sorry we cannot be more helpful.
