ESSENTIAL THINGS YOU NEED TO KNOW ABOUT THE ENERGY CAP

■ The energy cap is per unit of power. It does not cap your bill if you use more than “average”.

■ The cap does not include standing charges or other fees imposed by suppliers.

■ The regulator says the price cap is a “fairer” price – not the fairest.

■ Ask your supplier if you are covered by the cap – if you are, think about switching.

■ Households on warm home discount deals and those with pre-payment meters can be affected by the cap.
