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.

Who is eligible?
