Household Energy Costs

Site Guidance

All calculations on this site are based on current fuel prices they are checked regularly are automatically updated and were last changed on:-
19^th February 2013
For complete clarity, all calculation using current fuel prices are coloured red.

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.
