Save money on your gas and electricity bills

Mae’r dudalen yma ar gael yn Gymraeg.

This guide will help you lower your gas and electricity bills. It shows you ways to reduce your energy use, and ways to pay less for the energy you do use. There are lots of ways to save on energy bills – and a few small changes can help make a difference.

How can I use less energy?

Do a home energy check

Home improvements such as better insulation can reduce your energy bills.

To see what a difference they can make, start with a home energy check. For details, visit the Community Home Energy Check website.

Look into grants and benefits to help you save on home heat and insulation

Also try the Energy Savings Trust, who can advise on benefits, grants for home insulation, reduced tariffs and special payment options.

Look into government energy efficiency schemes

Then look into government initiatives that may be able to help pay for home improvements:

How to avoid wasting energy

  1. Use a timer on your central heating system. Set the heating and hot water to come on only when required.
  2. If you have a hot water tank, set the cylinder thermostat to 60oC (140oF).
  3. Close your curtains at dusk to stop heat escaping through the windows. Check for draughts, too.
  4. Always turn off the light when you leave a room.
  5. Use energy-saving light bulbs.
  6. Don’t leave appliances on standby or laptops and mobile phones on charge unnecessarily.
  7. When washing up, washing or drying by machine, try to fully load the appliance. One full load uses less energy than two half loads.
  8. Try to only boil the water you need.
  9. Turn taps off properly – in a single week, a dripping hot tap can waste enough hot water to fill half a bath.
  10. Dry your clothes outside during nice weather

How to pay less for the gas and electricity you use

Make sure you’re on the best tariff

Your supplier

Talk to your supplier or look at their website to see what tariffs they have available. Your bill must include personalised information about your supplier’s cheapest tariff and how much you could save. The bill will also give you estimated costs for the next year.

Other suppliers

Use a price comparison website to see if another supplier can make you a better offer.

Check if you’re eligible for a rebate or discount

Warm Home Discount

Some energy suppliers offer rebates and assistance to people who are of pensionable age, are disabled, have severe health problems or are on a low income.

Winter Fuel Payment

You could get between £100 and £300 to help pay your heating bills if you were born on or before 5 January 1952. This is the Winter Fuel Payment. You usually get a Winter Fuel Payment automatically if you get the State Pension or another social security benefit (not Housing Benefit, Council Tax Reduction or Child Benefit). If you qualify but don’t get paid automatically, you’ll need to make a claim.

  • Check whether you qualify by calling the Winter Fuel Payment helpline on 08459 151515.

Payment method discounts

You could save money on your bills by opting to switch from prepayment, cash or cheque payment methods to a monthly or quarterly direct debit. Most suppliers offer a discount if you opt to pay by direct debit, and it can help you avoid missing payments.
