You can save money on your energy bills by finding ways to improve your home’s energy efficiency.

There are quick and simple things you can do - for example:

  • change your heating controls so you stay warm but use less energy

  • check the cost of running your electrical appliances so you can decide how best to use them

You might also be able to make energy saving home improvements to improve your home’s energy efficiency.

Check your heating controls

You might be able to save money by changing the settings your heating controls.

You can:

  • turn down the temperature to the lowest comfortable setting

  • make sure your heating is only on when you need it

  • turn down radiators in rooms you use less often

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

Check how to save money heating your home.

If you use a storage heater, you can check how to use your storage heater efficiently.

If you use a different type of electric heating, find out about using room heaters on the Centre for Sustainable Energy website.

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 to use.

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

If you rent from a social housing landlord, they have to fix your heating - check how to report a repair.

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.

Check what to do about spray foam insulation

Spray foam insulation is a type of insulation which can be sprayed on the inside of roofs, in walls and floors. 

You should think carefully before having spray foam insulation installed. 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

If you’re not sure if you already have spray foam insulation, check the underside of your roof. You can do this by checking in your loft space. If you can’t safely access your loft, ask someone to help. 

If you have spray foam insulation installed you’ll see a bumpy cream, yellow or blue foam between the rafters. 

Roofs are the most common place to find spray foam insulation. It can also be installed in your walls or floors, but this is harder to check. 

If you have spray foam insulation and it’s not causing any problems, you might not need to get it removed. If you’ve been ‘cold called’ by a trader offering to remove your insulation, it might be a scam.

Before getting spray foam insulation installed

You should get independent advice from a buildings surveyor before getting spray foam insulation installed.

It can be expensive to get advice from a surveyor - check how much it will cost first. You can find a surveyor on the Royal Institute of Chartered Surveyors (RICS) website.

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. Check how to find a trader you can trust.

Spray foam insulation has a high cost compared to other types of insulation. You might find mineral wool insulation is cheaper and better at insulating.

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

Spray foam installation scams

If you’ve been ‘cold called’ by a trader or you’re being pressured into having spray foam insulation installed, it might be a scam.

There are reports of some traders incorrectly installing spray foam insulation, then charging for it to be removed.

Get the correct documents from your installer

Make sure you get paperwork from your installer. This should include:

  • a report from a survey that was done before any work started

  • product certificate showing what type of spray foam was used

  • guarantee from the trader who carried out the work

  • guarantee from the manufacturer of the insulation

If you already have spray foam insulation

You should have been given paperwork when the work was completed.

If a previous owner organised the work, check the paperwork from when you bought the property or ask your solicitor.

The paperwork should include:

  • a report from a survey that was done before any work started

  • product certificate showing what type of spray foam was used

  • guarantee from the trader who carried out the work

  • guarantee from the manufacturer of the insulation

If you’re trying to sell your home or remortgage, share this paperwork with your lender or solicitor. You can also share before and after pictures if you have any.

If you’re not happy with the installation of your spray foam insulation, there are things you can do. Check what to do if you have a problem with home improvements.

Spray foam insulation removal scams

If you’ve been ‘cold called’ by a trader or you’re being pressured into having your spray foam insulation removed, it might be a scam.

If your spray foam insulation isn’t causing you any problems, you might not need to get it removed. 

You should get independent advice before taking further action.

You might want to have your spray foam insulation removed if:

  • it’s causing damp and condensation

  • it’s causing damage to your property

  • you need to make a repair, for example if you’re repairing your roof and it’s covered with spray foam insulation

If you don’t have any problems with your spray foam insulation, you might not need to get it removed.

You should check with a building surveyor before you pay to have spray foam insulation removed. Tell your surveyor you want to check the quality of the work and whether it’s causing problems to your home. You can find a surveyor on the Royal Institute of Chartered Surveyors (RICS) website.

You can also check the Property Care Association for a ‘specialist spray foam assessor’. They can check the quality of the work and tell you if your spray foam insulation needs to be removed. Search your postcode to find a specialist spray foam assessor on the Property Care Association website.

Contact the Citizens Advice consumer service if you need more help - a trained adviser can give you advice over the phone or online chat.

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 registered as exempt from the ‘minimum standard’ of energy efficiency. You can check if your home is registered as exempt from the minimum standard on GOV.UK.

If your home is rated in band F or G on your EPC and not registered as exempt, your landlord might be breaking the law. 

If you complain to your landlord or letting agent, there’s a risk they’ll try to evict you. 

If you’re worried your landlord might evict you if you ask them to make improvements, talk to an adviser.

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.
