Grants available for Householders

Grants for Insulation and Heating Upgrades

The availability of grants to help households improve their property’s insulation and heating regularly change, so we recommend you contact us so we can advise you on the latest position and check if you qualify for help.

The Energy Company Obligation (ECO), provides grants to fund energy-efficient upgrades to homes, reducing carbon emissions and energy bills. ECO4 and The Great British Insulation Scheme (GBIS) schemes will run until 31 March 2026, however, new applications to the scheme will be difficult to complete in time.

Replacing the ECO scheme, the UK Government has announced the Warm Homes Plan, designed to boost energy-efficiency in the UK. The Government has announced it will be putting £15 billion of funding into a range of measures to upgrade homes and help families out of fuel poverty, by helping them to reduce their long-term energy bills.⁣ Measures include solar panels, heat pumps and batteries with free or low-interest loans and grants for households, aiming to make homes warmer and cheaper to run. ⁣⁠⁣
More details about how the scheme will work, including eligibility, will be announced later this year, so we’ll share advice and support when we have more information. Sign up to our newsletters for updates.

Boiler Grants

Our advice team frequently work to help low income vulnerable householders in Cornwall in crisis situations with no heating or hot water, to access other grants to repair and replace boilers. Please contact us to discuss your situation.

The Government’s Boiler Upgrade Scheme will provide upfront capital grants. These are to support the installation of heat pumps, and in some circumstances, biomass boilers.

Acting on behalf of property owners, installers can apply for:

  • £5,000 off the cost and installation of a biomass boiler
  • £7,500 off the cost and installation of an air source heat pump
  • £7,500 off the cost and installation of a ground source heat pump, including water source heat pumps.

You can find an installer in your area on the MCS website.

If you’d like to know which of these technologies is right for your property, contact our Cornwall Low Carbon Energy Advice Network team at email: lowcarbon@cep.org.uk to request a call back.
