Heating Oil Prices and Buying Guide

To calculate our average price of heating oil in the UK we collect a sample of quotes for delivery of 1000 litres of standard kerosene delivered in a standard tanker on normal delivery timescales (usually 1 week – 10 days). We do this once every quarter.


Fuel Prices

Domestic Fuel Prices

Most of this site is dedicated to giving its visitors useful indicative cost information related to the use of energy in and around your place of residence. Depending upon what is within your control where you live, it is hoped that this information will help you save money and help you make sensible cost based decisions regarding what equipment to invest in, to reduce costs.

Extracted Energy from Fuel

Extracted Energy from Fuel

For combustible fuels the fuel prices on the home page of this site and in the fuels page indicate the price per kWh of the fuels if burned at close to 100% efficiency. They indicate the maximum extractable, “locked up”, chemical energy within the fuels. No equipment (boiler or fire) burns the fuel with 100% efficiency. So the actual cost per kWh is always higher. This is indicated on many of the pages on this site, showing for example the difference between a modern boiler and an old inefficient boiler.


Carbon Dioxide and Fuel Costs

The site focuses on cost and the belief that if environmental measures are cost effective then people will adopt them. We show with evidence which are the most cost effective measures to adopt in your domestic situation to save you money and as a consequence help the environment and which costs need to be driven down or grant funded to increase uptake.

The site does not aim to cover in any detail CO2 emissions, even though these are of great importance to our future. There are so many sites on the internet focusing on this. Some awareness is however useful. The CO2 emission data from the below table is taken from the Carbon Trust. The table also has the cost data to compare with this so that you can get a feel for cost of energy and the consequence of the fuel type on the environment.

N.B. Wood Pellets do actually emit more CO2 than this when burned, but it is regarded as a renewable source and on growing more wood for more wood pellets the CO2 is reabsorbed by the growing trees. So the net CO2 emission is low.

Different fuel prices per kWh
Different fuel prices per kWh

Well from this we should all be burning wood pellets to keep warm, they are fairly cheap and their net carbon dioxide emissions are the lowest.  The problem is that if we all switched we would run out of trees and the price would go up!
