How to estimate your energy use

Our energy deal price comparison site Which? Switch can help you estimate how much gas and electricity you use.

Even if you don't have a recent energy bill to hand, you can still get an energy price comparison from Which? Switch based on typical energy consumption for your type of household.

Read on to find out how the process works.

Estimating how much energy you use

To figure out how much gas and electricity your household is using through Which? Switch, we will ask you a few straightforward questions about your home and the people living there. This is so we can work out whether you are a low, medium or high level energy user.

These estimates are drawn up in line with the average household energy consumption figures published by the energy regulator, Ofgem. 

We'll then use these estimates to work out your average annual energy use in kilowatt hours (kWh) to calculate your approximate average annual spend.

Estimated energy use figures

The table below shows the figures we have used to define high, medium and low annual energy usage for electricity, gas and Economy 7 (an electricity tariff that charges different rates for electricity used in the day compared to overnight).

These numbers are a general guide, so we’d ideally recommend entering your actual annual usage in kilowatt hours (kWh). Take a look at our article on how to decode your energy bills so you know where to find this information.

If you select 'I do not have a bill in front of me' on the Current Situation page of Which? Switch, you can compare prices using estimated average usage for the type of property you live in.

The figures below are estimated by the energy regulator Ofgem.
