Check your central heating

You might be able to save money by changing your heating controls - for example, by using thermostats and timers.

You can also find ways to keep heat in your home so your heating doesn’t need to be on as much.

If your heating doesn't work

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

If you rent your home, ask your landlord to fix the heating. They usually have to make sure your plumbing and heating work properly. Check what repairs your landlord has to do.

Check if you can use less electricity

It’s a good idea to find out how much your electrical appliances cost to run and how you could use them differently to save electricity.

Make improvements to your home

There are changes that can be made to your home to make it more energy efficient. This might include adding insulation or installing a more efficient heating system.

If you own your home, you can get recommendations for improvements you can make to your home on GOV.UK. This includes estimated costs of the improvements and how much you can save on your bills.

You might be able to get a grant to help you make improvements. Check if you can get help with the cost of improving your home’s energy efficiency.

If you live in an older home, there are some extra things you might need to think about before making changes to your home. Find out more about energy efficiency and older houses on the Historic England website.

Spray foam insulation

You should think carefully before having spray foam insulation installed. There are some risks with spray foam insulation that could cost you a lot of money.

The risks of spray foam insulation

Spray foam insulation can:

• have a high cost compared to other forms of insulation 

• reduce ventilation which can cause condensation and dampness

• cover up problems in your roof like leaks or damaged wood

• be very difficult to remove before making repairs

• lower the value of your property

• make getting a mortgage with some lenders difficult

You should get independent advice from a buildings surveyor before you have spray foam insulation installed. You can find a surveyor on the Royal Institute of Chartered Surveyors (RICS) website.

It can be expensive to get advice from a surveyor - check how much it will cost first.

If it costs too much to get advice from a surveyor, make sure you get at least 3 quotes from different home improvement traders. You can compare what types of insulation they recommend and how much it will cost.

You might find mineral wool loft insulation is cheaper and better at insulating.

You can find out more about using spray foam insulation on the RICS website.

Check what you should do if you have a home improvement problem caused by a trader.

If you rent privately

You must get your landlord’s permission before you make improvements to your home.

If your Energy Performance Certificate (EPC) says your home is rated in band F or G, your landlord normally has to make some improvements.

You can check your home’s EPC rating on GOV.UK.

Your landlord won’t have to make improvements if your home is exempt from the ‘minimum standard’ of energy efficiency. You can check if your home is exempt from the minimum standard on GOV.UK.

If your home’s EPC is rated in band F or G and it’s not exempt, write to your landlord and ask them to make improvements to your home. Tell them the EPC rating should be at least band E. Explain that you think it’s their responsibility.

You can complain to the council if your landlord won’t make the improvements - find your local council on GOV.UK.

If your home is exempt from the ‘minimum standard’ of energy efficiency, your landlord is still responsible for making any repairs or improvements to keep your home warm enough. Check what repairs your landlord has to do.

If you live in social housing

Your landlord has to make sure your heating and insulation is good enough to keep your home reasonably warm. 

If it isn’t, they might have to make repairs on your home. Check if your landlord has to repair your home and what you can do if they don’t.
