Government Grants for Home Improvements 2026

Quick overview: what's available

1. Boiler Upgrade Scheme (BUS)

The Boiler Upgrade Scheme is the big one for anyone considering switching from a gas boiler to a heat pump. The government provides a £7,500 grant towards the cost of an air source heat pump or ground source heat pump.

An air source heat pump typically costs £8,000–£15,000 fully installed. With the BUS grant, your out-of-pocket cost drops to roughly £500–£7,500. A ground source heat pump costs more (£15,000–£35,000) but the grant still takes a significant chunk off.

Who qualifies

• You own the property (homeowners and landlords both qualify)
• The property has a valid EPC (not older than 10 years)
• You're replacing a fossil fuel heating system (gas, oil, LPG, electric, or coal)
• Loft insulation must be at or above 100mm (or a valid reason why it can't be installed)
• The installer must be MCS-certified

How to apply

You don't apply directly. Your MCS-certified installer applies on your behalf through Ofgem's online portal. The grant is deducted from your installation cost - you just pay the difference. The whole process is straightforward, though there can be a wait for Ofgem to approve the voucher (typically 2–4 weeks).

The scheme runs until March 2028, but funding is allocated on a first-come, first-served basis. If you're seriously considering a heat pump, don't wait too long.

2. ECO4 (Energy Company Obligation)

ECO4 is the government's flagship scheme for helping low-income and vulnerable households improve their home's energy efficiency. It's funded by the big energy suppliers (the "Big Six" and others), who are legally required to deliver a certain number of improvements each year.

Under ECO4, eligible households can receive free improvements including:

• Boiler replacement - your old, inefficient boiler replaced with a new A-rated condensing model at no cost
• Loft insulation - topped up or installed from scratch
• Cavity wall insulation
• Solid wall insulation (in some cases)
• First-time central heating systems
• Heating controls and smart thermostats

Who qualifies

You need to meet two criteria: you must receive a qualifying benefit, and your home must have a low EPC rating (typically D, E, F, or G).

Qualifying benefits include:

• Universal Credit
• Pension Credit (Guarantee Credit)
• Child Tax Credit (with income below the threshold)
• Working Tax Credit (with income below the threshold)
• Income Support
• Income-based Jobseeker's Allowance (JSA)
• Income-related Employment and Support Allowance (ESA)
• Housing Benefit

There's also a "flex" eligibility route. If you don't receive benefits but have a low household income and live in a poorly-insulated home, your local authority can refer you. Contact your council to ask about ECO Flex.

How to apply

Contact your energy supplier directly, or find an approved ECO4 installer in your area. They'll check your eligibility, survey your property, and arrange the work. The ECO4 scheme ran until March 2026, and a successor programme (ECO5) is expected — check gov.uk for the latest information on available funding.

3. Great British Insulation Scheme (GBIS)

Formerly known as ECO+, the Great British Insulation Scheme focuses specifically on insulation. It's broader than ECO4 because you don't necessarily need to be on benefits - eligibility is partly based on your council tax band.

Who qualifies

There are two routes to eligibility:

• General group: your home is in council tax bands A–D (England) or A–E (Scotland and Wales), and the insulation measure is appropriate for your property type
• Low-income group: you receive a qualifying benefit (same list as ECO4) - this route covers council tax bands A–E and offers a wider range of measures

The scheme covers cavity wall insulation, loft insulation, flat roof insulation, room-in-roof insulation, and solid wall insulation (for the low-income group). The work is delivered by energy companies through their approved installers.

4. Local authority grants

Many local councils offer their own grants for home improvements, particularly energy efficiency measures. These vary hugely by area - some councils have generous schemes funded by central government allocations, while others have very little.

Common local grants include:

• Home Upgrade Grant (HUG2) - for off-gas-grid homes with EPC ratings of D, E, F, or G. Provides insulation, heating, and renewable energy measures. Worth up to £10,000 per property.
• Disabled Facilities Grant - up to £30,000 in England for adaptations that help disabled people live independently (stairlifts, wet rooms, ramps, door widening).
• Local energy efficiency schemes - many councils run area-based schemes targeting specific postcodes or housing types.

The simplest way to find out what's available in your area is to visit the government's energy efficiency advice page or call the Home Energy Scotlandhelpline if you're in Scotland. Your council's website should also list current schemes.

5. Other financial help

Beyond grants, there are other ways to reduce the cost of energy-related improvements:

• 0% VAT on energy-saving materials: insulation, solar panels, heat pumps, and other qualifying materials are zero-rated for VAT when installed in residential properties. This saves you 20% on the materials cost.
• Warm Home Discount: a £150 annual discount on your electricity bill if you receive Pension Credit (Guarantee Credit) or are on a low income. Applied automatically by your energy supplier.
• Winter Fuel Payment: £100–£300 per year for households with someone born before a qualifying date and receiving Pension Credit.
• Green mortgage products: some lenders offer lower interest rates or cashback for energy-efficient homes. Nationwide, Barclays, and NatWest all have green mortgage products.

How to maximise what you get

The schemes can be combined. For example, you could get cavity wall insulation through GBIS, a boiler upgrade through ECO4, and a heat pump through the Boiler Upgrade Scheme - all on the same property. The key is that each measure can only be funded once, and some schemes require a valid EPC before work starts.

Our advice: get a current EPC first (£60–£120). The recommendations on the certificate will tell you exactly which improvements will make the biggest difference, and your assessor can often advise which schemes your property is likely to qualify for.
