Site Prices Update
Last Updated28th June 2022
All calculations on this site are based on current fuel prices, they are checked regularly and calculations are automatically updated.
The costs calculated based on these fuel prices should be regarded as 'good estimates', given that fuel prices vary in different parts of the county and at different time of the year.
The calculations also have different levels of accuracy depending on the nature of the calculation. For example calculating the energy use of a known power output TV is very easy compared to calculating the effect on energy savings when insulating a cavity wall.

This is a very simple electricity cost calculator, it uses the time a device is switched on for, the power demand of the device in Watts (NOT kilo Watts) and and an electricity rate per unit - kWh, read more on watts and kWh Read More here.
Sample data is provided to give you an idea of what to put in the input fields. the UK avereage electricity rate is used in the example.
Just write over these numbers with your numbers. Please note the example shows a 3000 Watt device this is equal to 3kW, this might be the power consumption of an electrical heater to give to an idea.
List of devices and their indicative power demands
The table below shows a list of devices and their indicative power demand.
It is important to note here with this table that in certain countries in the world for example the USA and Canada the voltage is low, 110v. Because of this North Americans tend not to use devices we use in Europe (for example electrical kettles), this is because their power demand exceed the safe limit of their standard wall sockets.

|---|---|
| Small Fan heater | 1500 |
