Grants and funding, in one place.

Boiler Upgrade Scheme

Who runs it: Ofgem, on behalf of the Department for Energy Security and Net Zero.

What it helps pay for: part of the cost of replacing fossil fuel heating with a Heat Pump or a biomass Boiler. One grant per property: £7,500 towards an air source Heat Pump, £7,500 towards a ground source Heat Pump (including water source Heat Pumps and those on shared ground loops), £5,000 towards a biomass Boiler, £2,500 towards an air-to-air Heat Pump. Until March 2027, an additional £1,500 towards an air source or ground source Heat Pump if the property is heated by oil or LPG and has no mains gas connection. No grant for a hybrid Heat Pump system.

Who it is for: people who own the property, including a Business, a second home or a property rented out to tenants, and who are replacing fossil fuel heating such as oil, gas, electric or LPG. Most new build properties and social housing cannot get it. A biomass Boiler has further rules: off the gas grid, in a rural location.

Where to apply: you do not apply yourself. An MCS certified installer applies on your behalf on the Ofgem website, and the grant is taken off the amount you pay. Start at Apply for the Boiler Upgrade Scheme (GOV.UK).

It’s not for Solar. If anyone offers you “free Solar panels” on this grant, they’re selling you something else. See the scam patterns.

Warm Homes: Local Grant

Who runs it: your local council, with UK Government funding.

What it helps pay for: Energy-saving improvements to your home, arranged and paid for by your local council if you are eligible and the council has funding available. GOV.UK says the council might suggest wall, loft and underfloor Insulation, air source Heat Pumps, smart controls and Solar panels. If you have a landlord, they may need to pay for some of the improvements.

Who it is for: privately owned homes in England (owned by you or your landlord) with an Energy Performance Certificate of D, E, F or G. Household income must usually be £36,000 a year or less; if you earn more, you might still be eligible if you live in a certain postcode area or someone in your household gets certain benefits.

Where to apply: Apply for the Warm Homes: Local Grant (GOV.UK).

Energy Company Obligation (ECO4)

Who runs it: Ofgem, on behalf of the Department for Energy Security and Net Zero. The work is funded by medium and large Energy suppliers.

What it helps pay for: help with the cost of Insulation work, for example to your loft or cavity walls, and replacing or repairing your Boiler or other upgrades to your heating. Ofgem says being eligible does not necessarily mean a supplier or installer will decide to install anything in your home.

Who it is for: people who claim certain benefits and live in private housing, and people who live in social housing. The Energy efficiency rating of the home also counts.

Where to apply: contact your local council to find out if it is taking part, or contact an Energy supplier directly. Start at Help from your energy supplier: the Energy Company Obligation (GOV.UK).

Closing date: GOV.UK says the scheme is closing on 31 December 2026.

Smart Export Guarantee

Who runs it: Ofgem. The payments come from the electricity suppliers that take part, which Ofgem calls SEG Licensees.

What it helps pay for: nothing up front. It is a payment for the low-carbon electricity you export back to the grid, not a grant. Each supplier sets its own rate, contract length and terms, and Ofgem says the rate must always be above zero.

Who it is for: anyone in Great Britain with an eligible installation of Solar PV, wind, micro combined heat and power, hydro or anaerobic digestion, up to a capacity of 5MW (50kW for micro combined heat and power).

Where to apply: to a supplier that takes part. Ofgem tells generators to shop around. Start at Smart Export Guarantee (Ofgem).

VAT on Energy-saving products

Who runs it: it is a rate of VAT, not a scheme you apply to. Your installer is responsible for charging you the correct rate.

What it helps pay for: a 0% rate of VAT on certain Energy-saving products supplied by your installer and on the work to install them in your home, until 31 March 2027. HMRC says the rate goes back to 5% from 1 April 2027. The products listed include Insulation, Solar panels, ground source and air source Heat Pumps, and central heating and hot water controls. Not all products or installations qualify, and you cannot buy or install them yourself.

Who it is for: homes in Great Britain and Northern Ireland. HMRC's notice gives the zero rate from 1 May 2023 to 31 March 2027, and nidirect says the relief has been extended to Northern Ireland. One GOV.UK page still shows 5% for Northern Ireland, so check the rate on your quote and ask your installer.

Where to apply: nowhere. Check the rate on your quote against HMRC VAT Notice 708/6 (GOV.UK).

Home Energy Scotland Grant and Loan

Who runs it: Home Energy Scotland, funded by the Scottish Government.

What it helps pay for: clean heating systems and Energy efficiency work, as a grant, an interest-free loan or both. For heating systems such as Heat Pumps and heat network connections: grant funding of up to £7,500, with an additional £7,500 available as an optional interest-free loan. For Energy efficiency work such as Insulation: a grant of up to 75% of the combined cost, up to a maximum grant of £7,500. An uplift of £1,500 is available for rural and island homes to both grants. Funding is first come, first served and subject to availability.

Who it is for: homeowners in Scotland, for an existing property that is your only or primary private residence. You do not need to be getting benefits.

Where to apply: contact Home Energy Scotland first; an adviser refers you to apply. Start at Home Energy Scotland Grant and Loan.

Warmer Homes Scotland

Who runs it: the Scottish Government. You apply through Home Energy Scotland, and the work is delivered by Warmworks.

What it helps pay for: Energy-saving home improvements like heating and Insulation. Home Energy Scotland says eligible households could receive improvements worth £10,000 or more, and that in most cases the Scottish Government will meet all the costs.

Who it is for: homeowners and tenants of private landlords in Scotland who are struggling to heat their homes. There are rules on the home, how long you have lived there, and on age, health or benefits. Home Energy Scotland says the criteria may change from time to time.

Where to apply: contact Home Energy Scotland, or use its self-assessment tool first. Start at Warmer Homes Scotland (Home Energy Scotland).

Nest

Who runs it: the Welsh Government.

What it helps pay for: free advice for any household, and a package of free home Energy efficiency improvements for eligible households, such as a Heat Pump, Insulation or Solar panels. If your property is without heating or hot water, you may be eligible for a repair or replacement to Boilers or electric storage heaters.

Who it is for: people in Wales who own or privately rent their home, who receive a means tested benefit or live in a low-income household, and whose home has a low Energy Performance Certificate rating. The exact ratings and income thresholds are on the official page.

Where to apply: by phone or by asking Nest to call you back. Start at Get help with energy efficiency in your home from Nest (GOV.WALES).

Energy saving grants in your area (nidirect)

Who runs it: nidirect, the official government website for Northern Ireland. It points to NI Energy Advice, which offers independent advice and referrals to Energy grants, and to the Affordable Warmth Scheme, which is run by the Northern Ireland Housing Executive.

What it helps pay for: that depends on the scheme you are referred to. nidirect also says there is no financial support available for homeowners who wish to generate their own electricity through domestic Renewable technologies, such as Solar panels.

Who it is for: householders in Northern Ireland.

Where to apply: start at Energy saving grants in your area (nidirect).
