Make sure your home is energy efficient

This advice applies to Wales

You might be able to save money by making your home more energy efficient – for example by:

  • using your central heating effectively

  • keeping your home warm for longer

  • making changes so you use less electricity and gas

Check your central heating

You’ll spend more on energy if your heating system doesn’t work or isn’t set up properly.

Use timers and thermostats if you have them - this way you’ll only heat your house when necessary.

Find out how to set up your heating system on the Energy Saving Trust website.

If your heating doesn't work

Try to get it fixed as soon as possible so you don’t need to use things like electric heaters, which cost more.

If you rent, ask your landlord to fix the heating. It’s usually their duty to make sure your plumbing and heating works - check what your landlord has to do if you aren't sure.

Keeping your home warm for longer

You might be able to make improvements to your home - for example, adding insulation or installing a better heating system.

Contact Nest to get advice about improvements to your home and extra support you can get if you're on a low income.

If you're renting

If you’re renting and your Energy Performance Certificate says your home is in band F or G, your landlord normally has to make improvements. They won’t have to if your home is exempt - you can check if your home is exempt on GOV.UK.

Write to your landlord and ask them to make the improvements. Explain why you need the improvements and that you think it’s their responsibility.

If your landlord won’t make the improvements you can complain to the council - find your local council's contact details on GOV.UK.

Using less electricity and gas

There are ways to reduce how much electricity and gas you use - for example, you can:

  • use energy efficient light bulbs and turn off appliances at the wall if you aren’t using them

  • make sure your home is well insulated against drafts and close curtains in the evening to keep in heat

  • only use as much hot water as you need

  • fix any leaking taps

You can get more advice on using less electricity and gas on the Simple Energy Advice website.
