What is the maximum grant amount available per household?
26th March 2026
By Simon Carr
TL;DR: The maximum grant amount depends on the specific scheme, with the Disabled Facilities Grant offering up to £30,000 in England. Most energy-related grants, such as the Boiler Upgrade Scheme, provide between £7,500 and the full cost of installation. Your property may be at risk if repayments are not made on any additional financing used to cover costs beyond a grant.
What is the maximum grant amount available per household?
When looking to improve your home, whether for energy efficiency or accessibility, understanding the financial support available is essential. In the UK, various government-backed schemes exist to help homeowners reduce their carbon footprint or adapt their living spaces. However, there is no single “maximum” figure that applies to every situation. Instead, “what is the maximum grant amount available per household” depends entirely on the type of grant you are applying for, your location, and your personal circumstances.
Grants are typically non-repayable, but they often come with strict eligibility criteria. Some may cover the entire cost of a project, while others require a contribution from the homeowner. In this guide, we will break down the primary grants available in the UK and the maximum figures associated with each.
The Disabled Facilities Grant (DFG)
The Disabled Facilities Grant is one of the most significant forms of financial assistance for UK households. It is designed to help people with disabilities make essential changes to their homes, such as installing ramps, widening doors, or adding a downstairs bathroom. This grant is mandatory for local councils to provide if the applicant meets the criteria.
The maximum grant amount for the DFG varies across the UK:
- England: Up to £30,000.
- Wales: Up to £36,000.
- Northern Ireland: Up to £25,000.
In Scotland, a different system of “Equipment and Adaptations” support is managed through local councils and housing associations. The amount you receive may be means-tested, meaning your income and savings could affect the final figure. If the cost of the work exceeds the maximum grant, some local authorities may offer additional discretionary funding or top-up loans, though this is not guaranteed.
The Boiler Upgrade Scheme (BUS)
For those looking to transition to low-carbon heating, the Boiler Upgrade Scheme is the primary source of support. This scheme aims to encourage property owners to replace fossil fuel boilers with air source heat pumps, ground source heat pumps, or biomass boilers.
As of late 2023, the maximum grant amount available per household under this scheme was increased to £7,500 for both air source and ground source heat pumps. Biomass boilers are eligible for a grant of £5,000. This grant is provided as a voucher that is deducted from the total cost of installation by your chosen installer. It is important to note that this scheme is only available in England and Wales. Residents in Scotland can access similar support through Home Energy Scotland, which offers a mix of grants and interest-free loans.
The Energy Company Obligation (ECO4)
The ECO4 scheme is a government energy efficiency programme that requires medium and large energy suppliers to help households reduce their energy bills. Unlike other schemes, ECO4 does not usually have a fixed “maximum grant amount” in terms of a cash sum. Instead, it focuses on the “whole house” approach.
Under ECO4, eligible households may receive multiple measures for free, including:
- Internal and external wall insulation.
- Loft and roof insulation.
- Solar PV panels.
- Air source heat pumps.
Because the scheme covers the full cost of these installations for qualifying households, the value of the “grant” can often exceed £10,000 or even £20,000 depending on the extent of the work required. Eligibility is generally based on receiving certain benefits or living in a property with a low Energy Performance Certificate (EPC) rating.
Great British Insulation Scheme
Formerly known as ECO+, the Great British Insulation Scheme is designed to help a broader range of households who might not qualify for the full ECO4 programme. This scheme typically focuses on a single insulation measure, such as cavity wall or loft insulation.
While there is no set maximum cash amount, the scheme generally covers the majority of the installation cost. Some households in lower council tax bands with low EPC ratings may be required to pay a portion of the cost, while those on benefits may get the work entirely for free. You can check your eligibility for various energy schemes on the official government website.
Factors Influencing Your Grant Amount
Determining what is the maximum grant amount available per household involves looking at several variables. Firstly, your geographical location plays a huge role, as many schemes are devolved to the regional governments of Scotland, Wales, and Northern Ireland. Secondly, your household income and any benefits you receive will dictate whether you qualify for “means-tested” grants like the DFG or ECO4.
Thirdly, the current energy efficiency of your property matters. Many grants are targeted specifically at homes with EPC ratings of D, E, F, or G. If your home is already relatively efficient, you may find that the maximum grant amount available to you is lower, or you may not qualify for certain schemes at all.
Financing the Gap: When Grants Are Not Enough
Sometimes, the maximum grant amount does not cover the total cost of the improvements. For example, a full home retrofit or a complex disability adaptation might cost significantly more than the £30,000 DFG limit or the £7,500 heat pump voucher. In these cases, homeowners often look for additional ways to fund the project.
Some people choose to use savings, while others look at secured loans or remortgaging. Before taking on extra debt, it is wise to check your current financial standing.

If you are using a loan to bridge the gap, remember that your property may be at risk if repayments are not made. Failure to keep up with repayments could lead to legal action, increased interest rates, additional charges, and in the most serious cases, repossession of your home.
Using Bridging Loans for Property Improvements
In some circumstances, homeowners or investors use bridging loans to fund major works before a grant is paid out or before a property is refinanced. A bridging loan is a short-term finance option designed to “bridge” a gap in funding. These are generally split into two categories:
- Closed Bridging Loans: These have a fixed repayment date, usually tied to a specific event like the sale of a property.
- Open Bridging Loans: These have no firm end date but typically need to be repaid within 12 months.
In the UK, bridging loans differ from standard mortgages because interest is often “rolled up.” This means you do not usually make monthly payments; instead, the interest is added to the loan balance and paid in one lump sum when the loan ends. While this can help with cash flow during a renovation, it means the total debt grows over time. If you default on a bridging loan, the consequences can be severe, including high default fees and the risk of repossession.
People also asked
Can I get more than one grant for my house?
Yes, it is often possible to combine different grants, such as receiving an ECO4 grant for insulation and a Boiler Upgrade Scheme grant for a heat pump, provided you meet the individual eligibility criteria for each.
Do I have to pay back a government grant?
Generally, government grants for home improvements do not need to be repaid as long as you meet the conditions of the grant, such as staying in the property for a certain number of years.
Is the Disabled Facilities Grant means-tested?
For adults in England, the DFG is means-tested, meaning your income and savings will be assessed to determine how much you need to contribute; however, it is not means-tested for adaptations for children under 19.
What is the maximum grant for solar panels?
There is currently no direct cash grant for solar panels for all households, but the ECO4 scheme may cover the full cost of installation for low-income households or those on specific benefits.
Does a grant affect my credit score?
No, applying for or receiving a government grant does not involve borrowing money and therefore does not appear on your credit report or affect your credit score.
Final Considerations
Understanding what is the maximum grant amount available per household is the first step toward making your home more comfortable and efficient. While the figures can seem generous, always read the small print. Some grants require you to use specific approved installers, and others might require you to complete a home energy assessment first.
If you are planning significant works that exceed the grant limits, ensure you have a robust financial plan in place. Whether you are looking at a secured loan or a short-term bridging solution, always seek professional advice to ensure the product is right for your needs. Remember, any form of borrowing secured against your home carries risks. Always ensure you can afford the total cost, including any rolled-up interest or fees, to protect your property and your financial future.
