Question 2

Are energy prices higher in London than the rest of the UK?

Accepted Answer

Energy unit rates in London are broadly similar to the rest of England, as prices are largely set by the national Ofgem Price Cap. However, London households tend to have smaller properties with electric heating, which can affect overall bills. Switching to a fixed tariff can protect you from seasonal rises regardless of property size.
