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.

# Site Calculations

Throughout this site almost all calculations use the kilo Watt hour (kWh) as a unit of measure for energy.

The kWh was chosen as it is easy to relate to and is the standard measure for a unit of electrical energy on your electricity bill, i.e. 1 Unit = 1kWh. One kilo Watt (kW) is by the way 1000 Watts, and for completeness a Watt is a measure of power, which might be best described at the rate at which energy is transferred.

If you are considering investing in new technology in your house with a view to saving money on your energy bill, you should do the calculations to make sure it is really worth doing. Here are some simple steps to deducing if it worth doing on cost grounds alone.
