UK support for home energy upgrades now comes through targeted programmes such as the Energy Company Obligation, voucher schemes for low-carbon heating, the Warm Home Discount and local authority initiatives. The usual process is to get a quote from an accredited installer or your energy supplier, who can check eligibility and handle paperwork on your behalf.

Why look for grants and support

Saving energy at home cuts bills and helps reduce greenhouse gas emissions. Over the past decade the UK has moved from older schemes (for example, the Warm Front programme) to new, targeted programmes that fund insulation, more efficient heating and low-carbon systems.

Main routes to help today

  • Energy Company Obligation (ECO): Large energy suppliers fund insulation and heating measures for lower-income and vulnerable households. Suppliers normally work with registered installers to identify eligible measures and manage claims.
  • Boiler Upgrade Scheme and similar support: The government runs voucher and grant initiatives to help households switch to low-carbon heating such as heat pumps or biomass boilers. These schemes change over time, so check current availability with a trusted installer or the government website.
  • Warm Home Discount and bill rebates: Some households can get a one-off rebate or ongoing support from schemes that target low-income or vulnerable customers. Eligibility and delivery vary by supplier.
  • Local authority and devolved-nation programmes: Councils, devolved governments (Scotland, Wales, Northern Ireland) and housing associations often run complementary grants or loan schemes for energy upgrades.

How to apply and what to expect

The simplest route is usually through an approved installer or your energy supplier. They will:
  • Assess your property and produce a quote.
  • Check your eligibility for government schemes and supplier obligations.
  • Complete the paperwork and submit claims on your behalf if you agree to proceed.
If you prefer, you can contact your local authority or the relevant devolved government webpage to find local offers and application instructions.

Who is eligible?

Many programmes prioritise low-income households, people on certain benefits, those living in inefficient homes, or people with health vulnerabilities. Eligibility rules differ between schemes, so always check the specific criteria.

Practical tips

  • Get at least one written quote from an accredited installer.
  • Ask which programmes the installer will apply to and whether they handle administration.
  • Verify installer accreditation (TrustMark, MCS or relevant local registers) before agreeing to work.
  • If you rent, discuss upgrades with your landlord - some schemes include privately rented homes, others require landlord consent.

Where to find authoritative information

Start with gov.uk, your energy supplier's website, and your local council. Registered installers can advise on practical eligibility and handle applications for many schemes.

FAQs about Government Grants

Am I likely to get free insulation or heating upgrades?
Many programmes prioritise low-income or vulnerable households. Some people receive full funding; others get a partial grant. Eligibility varies by scheme, so request an assessment from an accredited installer or check your energy supplier's guidance.
How do I apply for support?
Contact an accredited installer or your energy supplier for a quote. They typically check your eligibility and can submit claims for the appropriate schemes if you accept their quote.
Do I need to pay upfront?
It depends. For fully funded measures you usually pay nothing, while partial funding may require a household contribution. Confirm payment terms with your installer before work starts.
Can renters get upgrades?
Some schemes cover privately rented properties, but landlord consent is often required. Social housing tenants have separate routes through housing providers.
