How to reduce your energy bill

The short answer

The quickest savings usually come from fixing what you're charged, not from using less. Start with the free checks, then look at your tariff and your home.

Free checks (do these first)

  1. Check your bill is right: rates, readings and the maths.
  2. Send regular meter readings so you're never billed on high estimates.
  3. Reclaim any credit and set a fair direct debit.
  4. Check your tariff: when it ends and whether a cheaper one exists.
  5. Claim compensation if your supplier missed a service standard (£40 each time).

Help you might be owed

  1. Warm Home Discount: £150 off your electricity bill if you get certain benefits. In England and Wales, the qualifying date for winter 2026 to 2027 is 23 August 2026. Your supplier must take part, and you or your partner must get a qualifying means-tested benefit and be named on the electricity bill. Most eligible households get it automatically (GOV.UK). Scotland has separate rules.
  2. Priority Services Register: free extra help if you're older, disabled, ill or have young children.
  3. Grants for insulation and heating. See Help to Heat on GOV.UK, the Energy Company Obligation and the Boiler Upgrade Scheme.

Small changes at home

  1. Turn your combi boiler's flow temperature down to around 60°C if it's set higher. Your home heats the same with less gas. [Check with your boiler manual.]
  2. Heat the rooms you use, with radiator valves turned down in empty rooms.

Frequently asked questions

What saves the most?

It depends on your situation. Fixing a billing error or leaving an expensive tariff often beats any home change.

Should I pay by direct debit?

It's often cheapest. Prepayment and pay-on-receipt rates differ.
