Government grants for home improvements are genuinely valuable for the borrowers who qualify, but they apply to a narrower set of circumstances than many people expect. Most grants are targeted at energy efficiency improvements, essential heating upgrades, and disability adaptations on lower-income households. Kitchen renovations, bathroom refits, extensions, loft conversions, and most cosmetic or structural improvements do not qualify for any current mainstream grant scheme. Understanding which schemes exist, who they are designed for, and what they cover is the starting point before any project budget is finalised.
For projects that do qualify, the principle is straightforward: apply for the grant first and build the loan around whatever the grant does not cover, if anything. A grant that fully covers the works eliminates the need to borrow entirely. A grant that partially covers the works reduces the loan amount and therefore the interest paid over the loan term. For projects that do not qualify for any grant, a home improvement loan is the practical funding route and the grant question does not arise. All grant eligibility information in this guide was accurate at the time of writing. Schemes change, open and close, and their eligibility criteria are updated regularly. Always verify the current position on GOV.UK before making any project or financial decisions based on grant availability.
At a Glance
- The main current grant schemes in England are the Boiler Upgrade Scheme, the Great British Insulation Scheme, ECO4, and the Disabled Facilities Grant. Each covers a different type of work and has different eligibility criteria. Scotland, Wales, and Northern Ireland have their own equivalent schemes: the named government schemes and who qualifies.
- For most home improvements, no grant exists. Kitchen renovations, extensions, loft conversions, bathroom refits, decoration, and most structural works do not qualify for any current mainstream scheme. A home improvement loan is the appropriate funding route for these projects: when a grant covers everything and when a loan is still needed.
- The correct sequencing is: check grant eligibility first, then plan the loan around the shortfall. Arranging a loan for the full project cost before checking grant eligibility means potentially borrowing money for works that could have been funded at no repayment cost: how grants and loans interact.
- Grant timelines are longer than loan timelines. A grant application for ECO4 or the Great British Insulation Scheme may take several weeks or months from application to confirmed installation. If the project is urgent, a loan may be needed regardless of grant eligibility: when a grant covers everything and when a loan is still needed.
- Scotland, Wales, and Northern Ireland have their own schemes with different eligibility and coverage. This guide focuses on England. Residents of other UK nations should check the relevant devolved authority website for current schemes: the named government schemes and who qualifies.
The Named Government Schemes and Who Qualifies
The following schemes were the main active government grant programmes for home improvements in England at the time of writing. Eligibility criteria, funding levels, and availability change. Verify the current position on GOV.UK before making any project decisions based on grant availability.
Boiler Upgrade Scheme (BUS)
Heat pump replacementThe Boiler Upgrade Scheme provides a voucher to reduce the upfront cost of installing an air source heat pump, ground source heat pump, or biomass boiler as a replacement for a fossil fuel heating system. The voucher amount at the time of writing is £7,500 for heat pumps and £5,000 for biomass boilers, applied directly by the installer at the point of installation. The scheme is available to owner-occupiers and landlords in England and Wales.
Who qualifies
Owner-occupiers and landlords. No income threshold. Property must have a valid EPC and any recommended insulation must be in place or installed alongside.
What it does not cover
Does not cover gas or oil boiler replacements. Does not reduce the cost to zero: heat pumps typically cost £8,000 to £15,000 installed. A loan for the balance is commonly needed.
Great British Insulation Scheme (GBIS)
InsulationThe Great British Insulation Scheme funds a single insulation measure per property, delivered through approved installers at no cost to the homeowner or at a reduced contribution. The primary target is properties with an EPC rating of D or below. Two eligibility routes exist: a means-tested route for households receiving certain benefits, and a general group for lower-rated properties regardless of income, where local authority referral may be required.
Who qualifies
Households on qualifying benefits (means-tested route) or households in EPC D or below (general route). Owner-occupiers and some private renters. Eligibility varies by local authority area.
What it covers
One insulation measure: loft insulation, cavity wall insulation, solid wall insulation, or similar. Does not cover multiple measures or wider renovation works.
ECO4 (Energy Company Obligation)
Energy efficiency packageECO4 is funded by the major energy suppliers and targets low-income households in properties with low EPC ratings. Unlike GBIS, ECO4 can fund a package of measures rather than a single measure: insulation, heating upgrades, and in some cases solar panels, depending on the property’s starting position and what the assessment identifies as most beneficial. The works are delivered at no cost to the household.
Who qualifies
Households receiving qualifying means-tested benefits and living in properties with EPC rating E, F, or G. Owner-occupiers and private tenants (with landlord consent). Local authority referrals are available for households not on qualifying benefits but living in fuel poverty.
What it does not cover
Does not cover works outside the energy efficiency scope. Kitchen, bathroom, or structural works are not included. New-build properties and those with EPC A to D typically do not qualify.
Disabled Facilities Grant (DFG)
Disability adaptationsThe Disabled Facilities Grant is means-tested and administered by local housing authorities. It funds adaptations that enable a disabled person to live safely and independently in their home: ramps and level access, accessible bathrooms, stair lifts, widened doorways, and adapted kitchen facilities. The maximum grant in England at the time of writing is £30,000, though the amount awarded depends on assessed need and a means test of household income. Applications are made through the local authority and require an assessment by an occupational therapist.
Who qualifies
Disabled persons (or households with a disabled occupant) in England. Means-tested based on household income. Owner-occupiers and private tenants. Landlords can also apply for works to rental properties occupied by disabled tenants.
Loan interaction
Where the assessed need exceeds the grant maximum, or where the means test reduces the award, a loan may be needed for the balance. Some local authorities operate top-up loan schemes alongside the DFG.
How Grants and Loans Interact
The practical sequencing for any project that may qualify for a grant is: establish grant eligibility first, confirm the grant amount, and then plan the loan around the shortfall if one exists. This sequencing matters because arranging a loan for the full project cost before checking grant eligibility means potentially borrowing and paying interest on money that could have been provided without repayment. Even where the grant covers only a portion of the total cost, the portion it covers reduces the loan amount, the monthly repayment, and the total interest over the loan term.
The interaction between grants and loan affordability is generally positive. A confirmed grant that covers part of the project cost reduces the loan amount needed, which improves the affordability assessment for the loan and reduces the monthly commitment. The grant is not income for loan affordability purposes and does not directly improve the credit profile, but the smaller loan amount means a lower monthly repayment that is easier to service on the same income. Our guide to budgeting before you borrow covers how to build the loan calculation once the grant amount is confirmed, including how to size the contingency on a project that is partially grant-funded. Our guide to combining home improvement loans with other financing covers the blended approach in more detail.
When a Grant Covers Everything and When a Loan Is Still Needed
ECO4, where a household fully qualifies, typically covers the entire cost of the recommended energy efficiency package with no contribution from the household. For a qualifying household in an EPC E, F, or G property, the works may be carried out at zero upfront cost. In this scenario, no loan is needed for the energy efficiency works, and the project question becomes whether any additional works beyond the ECO4 scope are wanted and whether those need separate funding.
In most other grant scenarios, the grant covers part of the cost and a loan covers the remainder. The Boiler Upgrade Scheme reduces the cost of a heat pump by £7,500 but does not eliminate it: a heat pump costing £12,000 installed still requires £4,500 in additional funding after the BUS voucher. The Great British Insulation Scheme covers a single insulation measure but not heating, structural, or other works. The Disabled Facilities Grant covers up to £30,000 of adaptation costs but is means-tested and may award less than the maximum, leaving a balance for the household to fund. In all of these cases, a home improvement loan for the residual amount is the natural complement to the grant. The loan is smaller than it would have been without the grant, which is the financial benefit of checking grant eligibility before fixing the loan amount.
Scotland, Wales, and Northern Ireland: the schemes described above apply to England. Scotland has its own Home Energy Scotland scheme and Warmer Homes Scotland programme. Wales has the Nest and Optimised Retrofit programmes. Northern Ireland has the Affordable Warmth Scheme. Each has different eligibility criteria and coverage. Residents of devolved nations should check the relevant government website for their applicable schemes rather than relying on England-specific information.
Grants vs Loans: The Key Differences
The table below sets out the practical differences between grant funding and loan funding across the factors that matter most for a homeowner planning a home improvement project.
| Factor | Government grant | Home improvement loan |
|---|---|---|
| Repayment | None where the grant is awarded and conditions are met. Some local authority grants are repayable if the property is sold within a defined period. | Full repayment with interest over the agreed term. Monthly repayment is a committed outgoing for the duration of the loan. |
| Scope of works covered | Narrow. Current mainstream schemes cover heat pump installation, single insulation measures, energy efficiency packages, and disability adaptations. Most renovation works do not qualify. | Broad. A home improvement loan can fund any lawful renovation work. Lenders do not typically restrict the type of works funded. |
| Eligibility | Scheme-specific. Most energy schemes require low EPC rating, low household income, or specific qualifying benefits. The Boiler Upgrade Scheme has no income threshold but covers only heat pump and biomass installation. | Based on credit profile, income, and for secured products, property equity. No restriction based on property EPC rating or benefit status. |
| Timeline | Typically longer than a loan. Grant applications involve eligibility checks, assessments, and approved installer availability. ECO4 and GBIS can take several months from enquiry to completed installation. | Faster. An unsecured personal loan can be arranged in one to three working days. A secured loan takes two to four weeks. Funds are available before works begin. |
| Certainty | Not guaranteed. Grant funding is finite and schemes can close or change eligibility criteria. An application that is in progress when a scheme closes may not be completed. | More certain once approved. A loan offer is a binding commitment from the lender, subject to the standard cancellation rights under the Consumer Credit Act. |
| Effect on credit file | None. Grants do not appear on the credit file and do not affect affordability assessments for other borrowing. | A loan appears on the credit file as a committed monthly liability. It is factored into affordability assessments by any future lender during the loan term. |

Checking won’t harm your credit scoreFrequently Asked Questions
Can I apply for a grant and a loan at the same time?
Yes. There is no rule preventing a homeowner from applying for a grant and arranging a loan simultaneously, and for projects that combine grant-eligible works with works outside the grant scope, doing both in parallel is often the most practical approach. The grant covers the eligible element and the loan covers the rest. The sequencing consideration is that the loan amount should ideally be confirmed after the grant amount is known, so that the loan is not larger than needed. If the grant application is in progress but not yet confirmed, the loan can be arranged for the full project cost and reduced at drawdown if the grant is confirmed before the loan completes, subject to the lender’s terms on loan amount changes after approval.
For ECO4 and GBIS, the works are delivered directly by the approved installer with no upfront payment from the homeowner, so no loan is needed for the grant-covered element. The loan question is only relevant for any additional works outside the scheme scope. For the Boiler Upgrade Scheme, the £7,500 voucher is applied by the installer at the point of installation and reduces the invoice amount. The homeowner pays the balance, which may come from savings or a loan. The loan can be arranged in advance of the installation based on the expected net cost after the BUS voucher.
What happens if my grant application is declined after I have planned the project?
A declined grant application does not prevent the project from proceeding. It changes the funding position: the full project cost is now the loan amount rather than the shortfall after the grant. If a loan had already been arranged for the shortfall amount, a top-up or a new loan for the full amount may be needed. For this reason, it is worth either arranging the loan for the full project cost from the outset and treating the grant as a bonus that reduces the amount drawn, or waiting for grant confirmation before finalising the loan amount.
Grant applications are declined for several reasons: the property EPC rating does not qualify, the household income is above the scheme threshold, the recommended measures have already been installed, or the scheme has reached its funding allocation for the period. Where an application is declined on eligibility grounds that can be addressed, such as an out-of-date EPC that does not reflect recent improvements, it may be worth addressing the issue and reapplying. Where the decline is on income grounds or because the scheme is full, the loan-only route is the practical path forward. Our guide to home improvement loans for energy efficiency upgrades covers the loan options for energy works where grant funding is not available.
Do grants affect the loan affordability assessment?
A confirmed grant reduces the loan amount needed, which improves the affordability position for the loan. A smaller loan amount produces a lower monthly repayment, which is easier to service on the same income and reduces the debt-to-income ratio that lenders assess. In this sense, a grant has an indirect positive effect on loan affordability by reducing the amount that needs to be borrowed.
A grant payment itself is not treated as income for loan affordability purposes by mainstream lenders, because it is a one-off capital payment rather than a recurring income stream. An ECO4 installation that reduces the household’s monthly energy costs does, however, improve disposable income in a way that is relevant to the overall financial position, even if not directly assessed by the lender. A lower monthly energy bill means more disposable income available for loan repayments. This indirect benefit is real but should not be overstated in any affordability self-assessment, because lenders use their own energy cost assumptions rather than the actual household bill.
Are there grants available for landlords improving rental properties?
Some grant schemes are available to landlords, though the eligibility and terms differ from owner-occupier routes. The Boiler Upgrade Scheme is available to landlords in England and Wales for properties where a fossil fuel heating system is being replaced with a heat pump or biomass boiler. The grant is claimed by the installer, who reduces the invoice amount, and applies regardless of whether the property is owner-occupied or privately let.
ECO4 is available in the private rented sector where the tenant meets the qualifying benefit criteria and the landlord consents to the works. The Disabled Facilities Grant is available for works to rental properties where the disabled person is the tenant and the landlord applies on their behalf, or where the landlord is required to make adaptations under disability discrimination legislation. GBIS is available in the private rented sector under certain conditions, though the property must meet the EPC eligibility criteria. Landlords considering energy efficiency improvements for rental properties should check the current position on GOV.UK and consider the MEES compliance implications alongside the grant question. Our guide to home improvement loans for rental properties covers the financing options available to landlords in more detail.
Squaring Up
Government grants for home improvements are worth checking before any loan is arranged, but they apply to a narrow set of works and households. The Boiler Upgrade Scheme, Great British Insulation Scheme, ECO4, and the Disabled Facilities Grant each have specific eligibility criteria that most homeowners planning a general renovation will not meet. For the households and works that do qualify, the financial benefit is significant: works carried out at reduced or zero cost eliminates or substantially reduces the amount that needs to be borrowed and the interest paid over the loan term.
The practical approach is simple: check grant eligibility first, confirm the grant amount if applicable, and size the loan to cover the shortfall. For projects that fall entirely outside any grant scheme, a home improvement loan is the funding route and the grant question does not arise. Grant information changes frequently. The position on GOV.UK is the authoritative source and should be checked before any project decision is made based on assumed grant availability.
