Solar panel grants for businesses: what is actually available
Most searches for solar grants for business end in disappointment, and it is better to say so here than after a survey. There is no general UK grant towards solar panels on a private commercial building. Several adjacent schemes do exist, and this page sets out plainly which ones a business can use for solar and which ones it cannot, alongside the support that is real: tax relief, VAT recovery, export income and, for the public sector only, grant funding.

There is no general grant for commercial solar
A commercial solar grant, in the sense of public money towards panels on a private company's building, does not exist in the UK.
No scheme currently pays a private company a capital contribution towards a rooftop array on its warehouse, factory or office simply for installing one. The Feed in Tariff closed to new applicants in 2019 and was replaced by the Smart Export Guarantee, which pays for exported units rather than for installing anything. Everything else marketed as free solar grants for business is either a loan, a scheme for a different technology, or a lead generation page using the word grant to mean something else.
The honest version is that government support for a commercial array is real but arrives through the tax system and through the value of the energy, not through a cheque. That changes how you build the case internally. You are not waiting for an award before proceeding.
It also means the adjacent schemes are worth understanding rather than dismissing. Several of them are genuine government funding, and one or two may apply to something else you are doing to the same building in the same year. They just will not pay for the panels.
One more thing is worth saying before the detail. Companies usually arrive here for one of two reasons: business energy bills that have moved faster than anything else on the profit and loss account, or a net zero commitment with a date attached to it. Both are good reasons to put panels on a roof. Neither is improved by waiting for business grants that do not exist, and a scheme that only works with a grant is a scheme that does not work.
What kind of organisation are you?
-
A public sector body in England
School, further education college, council, emergency service or NHS estate
Public Sector Decarbonisation Scheme, delivered by Salix Finance on behalf of central government. Phased windows, competitive, and historically weighted towards heat decarbonisation with supporting measures rather than standalone solar.
-
A farm inside a designated landscape
Farmers and land managers inside a National Park or a National Landscape
Farming in Protected Landscapes, a Defra programme run through the local National Park and National Landscape teams. It funds projects under climate, nature, people and place, and solar panels are not a listed item. Where a project benefits the applicant commercially, the programme funds only a proportion of the cost.
-
An industrial site with a genuine process load
Process heat, kilns, ovens or compressors serving production, not building services
Industrial Energy Transformation Fund. Competition windows rather than a standing scheme, historically competitive and part funded, and aimed at energy used in an industrial process. A distribution warehouse with racking and forklifts is unlikely to qualify on that basis.
-
A private company in a warehouse, factory or office
Any trading company outside the three branches above
No capital grant. No UK scheme pays a trading company a contribution towards panels on its own roof. What applies instead:
- capital allowances HMRC treats solar panels as integral features, so the cost goes into the special rate pool and is claimed through the capital allowances regime rather than written off as a running cost.
- VAT The work on a commercial building carries VAT at the standard rate, and a VAT registered business making taxable supplies recovers it as input tax in the normal way.
- Smart Export Guarantee Income per unit exported, at a rate the supplier sets. It improves a scheme rather than rescuing a weak one.
- green business lending Repayable with interest, and generally unregulated business lending. A loan is not a grant, whatever a round up page calls it.
Which schemes cover solar, and which do not
The table below sets out, scheme by scheme, whether a business can use it for solar PV, who it is open to and where the rule comes from.
- You are a public sector body in England applying to the Public Sector Decarbonisation Scheme through Salix Finance
- You farm inside a National Park or a National Landscape, where Farming in Protected Landscapes may fund a project, though solar panels are not a listed item
- You run a genuine industrial process, for the Industrial Energy Transformation Fund
- You are installing EV chargepoint sockets rather than generation, under the Workplace Charging Scheme
- You are a private trading company in a warehouse, a factory or an office
- The building sits on an industrial estate outside a designated landscape
- The load is racking, forklifts, lighting and building services rather than an industrial process
- What you have been offered is a green business loan, which is repayable with interest

The Boiler Upgrade Scheme covers heat, not solar panels
The Boiler Upgrade Scheme is a government grant towards the cost of installing an air source heat pump, a ground source heat pump or, in limited circumstances, a biomass boiler, in homes and small non domestic buildings in England and Wales.
gov.uk sets out the Boiler Upgrade Scheme rules and the current grant levels, checked September 2026. It is the scheme most often mentioned in the same breath as commercial solar, so it is worth being exact about it.
Solar panels are not an eligible measure under the Boiler Upgrade Scheme. The scheme is about replacing fossil fuel heating with a low carbon heat pump, so it reduces carbon emissions from heating rather than generating electricity. The installer has to be certified under the Microgeneration Certification Scheme and the application is made by that installer, not by you.
It is still worth knowing about for two reasons. If you heat a small office block or a trade counter with an ageing gas boiler, the Boiler Upgrade Scheme and a solar array are complementary rather than competing, because a heat pump raises daytime electricity demand and a heat pump plus panels raises the share of generation you consume on site. And if a salesperson tells you the Boiler Upgrade Scheme will contribute towards your panels, you now know that it will not.
Green business loans are lending, not business grants
A green business loan is lending marketed for energy efficiency or renewable energy work, repayable with interest, and a large part of what the internet calls green business grants is in fact one of these.
High street banks, challenger banks and platform lenders such as Funding Circle all market business loans aimed at energy efficiency and renewable energy work, and some carry a preferential rate or a fee holiday attached to a green purpose. A loan is repayable with interest. A grant is not.
That does not make green business loans a bad route. For a company with no spare capital but a strong trading record, a loan against the covenant of the business is often cheaper over a long term than a power purchase agreement, because you keep the asset, the export income and the capital allowances.
Lending to a limited company for business purposes is generally unregulated business lending, so the protections that apply to consumer credit do not apply. We are not authorised or regulated by the Financial Conduct Authority and we do not give financial advice. We introduce you to funders and pass on what they quote.
Is the Industrial Energy Transformation Fund relevant to a warehouse?
The Industrial Energy Transformation Fund, usually shortened to IETF, is a government grant fund for energy efficiency and deep decarbonisation at industrial sites.
It is the largest pot of government money in this area and the one most often cited on grant round up pages, and it has run in competition windows rather than as a standing scheme. gov.uk lists open and recently closed windows on its find funding to help your business become greener page, checked September 2026.
The test that matters for most readers of this page is what the IETF counts as industrial. The fund is aimed at energy used in an industrial process, not at the energy used to light, heat and run a building. A distribution warehouse with racking and forklifts is unlikely to qualify on that basis, while a manufacturing site with process heat, kilns, ovens or compressors serving production may well do. If you occupy an industrial unit with a genuine process load, the IETF is worth the application. If you occupy a shed, it is not, and an adviser who suggests otherwise has not read the criteria.
Two further points. IETF grants have historically been competitive and part funded, so you contribute to the project cost rather than receiving the whole of it. And an IETF application needs a costed, designed scheme with a delivery programme, which takes longer to produce than a window usually stays open. The survey work is what puts an industrial site in a position to apply at all.
Note also what the IETF has tended to fund: heat recovery, process controls, energy efficient motors and drives, and fuel switching. On site generation has featured as part of a wider package rather than as the object of the application. If solar is the whole of your plan, this is not your fund.
The same holds for the other central government pots that appear on grant round up pages. Separate funding exists for heat networks, for hydrogen and for carbon capture, and none of it reaches a rooftop renewable energy scheme on a commercial building. Where a growth sector fund does mention on site generation, it is usually as one eligible item inside a larger decarbonisation project rather than as something you can apply for on its own.
Workplace charging, farm funding and the other adjacent schemes
Workplace Charging Scheme
The Workplace Charging Scheme gives businesses, charities and public sector bodies a voucher towards the cost of buying and installing electric vehicle chargepoint sockets at a site with off street parking, claimed through an authorised installer.
gov.uk sets out the Workplace Charging Scheme eligibility and the cap per socket, checked September 2026. It pays for chargepoints, not for generation, so it will not contribute a penny towards panels.
It is still relevant to a solar decision. Chargepoints on a yard are one of the most effective ways to increase energy efficiency on paper and self consumption in practice, because vehicles charging through the working day soak up generation that would otherwise be exported at a low rate. A business installing both in the same year should sequence them together.
Farming in Protected Landscapes
Farming in Protected Landscapes is a Defra programme delivered through National Park and National Landscape teams, funding projects by farmers and land managers inside those designated areas under the themes of climate, nature, people and place. Solar panels are not a listed eligible item. Where a project does go ahead and the applicant benefits commercially, the guidance is explicit that the programme funds only a proportion of the cost, and the amount depends on how much the project benefits the business. An array that cuts your own electricity bill is a commercial benefit. Source: gov.uk, funding for farmers in protected landscapes, checked September 2026.
The eligibility is geographic and occupational, not sectoral. If you farm inside a National Park or a National Landscape, it is worth a conversation with the local team before you commit to a scheme. If your building sits on an industrial estate outside a designated landscape, this is not a route, whatever a grant round up page implies.
Regional, devolved and growth hub funding
Regional and devolved funding for business energy work is administered separately in Scotland, Wales and Northern Ireland, and it changes too often for any website to list reliably.
Searches for business solar panel grants in Wales, Scotland or Northern Ireland mostly lead to a business energy advice service and a loan rather than to capital business grants. What follows is where to look rather than what is open today.
- Scotland. Business Energy Scotland provides a free advice service to small and medium sized businesses and administers an energy efficiency loan with a cashback element, funded by the Scottish Government and delivered by Energy Saving Trust. Renewables have been eligible under that loan. Checked September 2026.
- Wales. Business Wales is the devolved business support service and the route to whatever Welsh Government funding is open in a given year, including the Development Bank of Wales for lending. Business solar panel grants in Wales are usually lending or advice rather than capital business grants.
- Northern Ireland. The Northern Ireland Sustainable Energy Programme, overseen by the Utility Regulator, funds sustainable energy measures through licensed suppliers, with most of the spend directed at households. Invest Northern Ireland is the route for business support and for what business funding exists.
- London. The Mayor of London's Energy Efficiency Fund invests in low carbon and energy efficiency projects across the capital. It is an investment fund rather than a grant fund, so it lends into schemes of scale rather than writing cheques for a single roof.
- Growth hubs and local authorities. Local growth hubs in England offer free business support and know what is open in their area. Some district and county councils have run small business energy efficiency grants, often capped at a few thousand pounds and usually oversubscribed within days of opening. A growth hub will also tell you when a scheme you have read about has closed.
Capital allowances on solar panels
Why solar sits in the special rate pool
The special rate pool is the capital allowances pool that holds expenditure on integral features of a building, and HMRC treats solar panels as integral features, so a commercial array goes into it rather than into the main pool.
That classification is the single most important tax fact about a commercial array, because it decides which allowances and which rates are in play.
What that means for the year of spend
Special rate expenditure can be covered by the Annual Investment Allowance, subject to the limit and to whatever else the company has already spent on qualifying assets in the same period. Where the spend runs past that, the balance is written down at the special rate over subsequent years. We do not calculate relief, we are not qualified to, and the figure is specific to your company's profits and capital programme. Give the quotation to your accountant and ask what can be claimed and when.
Who claims when a funder owns the array
The allowances follow ownership. Buy outright, or through a loan or hire purchase, and the claim is normally yours. Take an operating lease or a power purchase agreement and the funder owns the asset, claims the allowances and prices that benefit into what it charges you.
- the spend
Capital cost of the array
Design, equipment and installation. Capital expenditure, not a revenue expense, so it is not written off in one line in the profit and loss account.
- classified
An integral feature of the building
HMRC treats solar panels as integral features. That single classification decides which allowances and which rates are in play.
- pooled
The special rate pool
The capital allowances pool that holds expenditure on integral features, rather than the main pool.
Annual Investment Allowance
Special rate expenditure can be covered by it, subject to the limit and to whatever else the company has already spent on qualifying assets in the same period.
Written down at the special rate
Whatever the Annual Investment Allowance does not cover is carried in the pool and written down over subsequent years.
If a funder owns the array, under an operating lease or a power purchase agreement, the funder claims the allowances instead and prices that benefit into what it charges you.
We do not calculate relief and we are not qualified to. The figure is specific to your company's profits and capital programme, so give the quotation to your accountant.
VAT on solar panels for business premises
The zero rate for energy saving materials is a VAT relief that applies to installations in residential accommodation and in buildings used for a relevant charitable purpose.
It is often quoted in commercial solar sales material, and it is being quoted out of context: a distribution warehouse is neither residential nor charitable, so the work carries VAT at the standard rate.
For most businesses this is a cash flow question rather than a cost. A VAT registered company making taxable supplies recovers the input tax in the normal way.
The Smart Export Guarantee is income, not a grant
The Smart Export Guarantee, administered by Ofgem, requires larger licensed electricity suppliers to offer a tariff for units exported to the grid.
Export rates are ordinarily well below what you pay to import, which is why the survey works so hard on your half hourly consumption. A building that uses most of its generation on site is displacing expensive imported electricity and cutting its energy bills at the full import price. A building that exports heavily is selling cheaply. The Smart Export Guarantee improves a scheme. It rarely makes a weak one work.
- VAT The zero rate for energy saving materials covers residential accommodation and buildings used for a relevant charitable purpose, so a commercial building is charged at the standard rate. A VAT registered business making taxable supplies recovers it in the normal way, which makes it a cash flow question rather than a cost. Charities, mixed use buildings and partly exempt businesses need proper advice.
- Capital allowances Solar sits in the special rate pool. The Annual Investment Allowance can cover special rate expenditure, subject to the limit and to whatever else the company has already spent on qualifying assets in the same period. Whatever it does not cover is written down at the rate in force over subsequent years.
- The energy itself Units used on site displace the price you pay to import. Units exported earn the Smart Export Guarantee rate the supplier sets, and suppliers compete on it, so there is no single national figure. This is the strand that runs for as long as the array does.
If a funder owns the array, under an operating lease or a power purchase agreement, the capital allowances lane is the funder's rather than yours.
- value coming back to the business
- cash going out first
The same figure as a table
| Support | When it lands | What happens, and on whose terms |
|---|---|---|
| VAT | on the invoice | Charged at the standard rate, because a commercial building is neither residential accommodation nor used for a relevant charitable purpose. |
| VAT | on the VAT return | Recovered as input tax in the normal way by a VAT registered business making taxable supplies. A cash flow question rather than a cost. |
| Capital allowances | in the year of spend | The Annual Investment Allowance can cover special rate expenditure, subject to the limit and to what else the company has already spent on qualifying assets that period. |
| Capital allowances | in later periods | Whatever the Annual Investment Allowance does not cover stays in the special rate pool and is written down at the rate in force over subsequent years. |
| The energy itself | every year it generates | Units used on site displace the price you pay to import. Exported units earn the Smart Export Guarantee rate the supplier sets, and there is no single national figure. |
| If a funder owns the array | for the term | Under an operating lease or a power purchase agreement the funder owns the asset and claims the capital allowances, and prices that benefit into what it charges you. |
Salix and the Public Sector Decarbonisation Scheme
The Public Sector Decarbonisation Scheme is a government grant programme, delivered by Salix Finance on behalf of central government, that funds energy measures for public sector bodies in England, including schools, further education colleges, councils, emergency services and NHS estates.
Real grant funding for solar in the UK is concentrated there. Private companies cannot apply. The scheme runs in phases with their own windows, criteria and weightings, and it has historically leaned towards heat decarbonisation with supporting measures rather than standalone solar.
If you are a school business manager or an estates lead, the practical point is that a funding window needs a costed, designed scheme ready to submit, and that takes longer to produce than the window usually stays open. Getting the roof surveyed early is what puts you in a position to apply at all.
How we quote when there is no grant to wait for
A commercial solar decision with no grant pending comes down to measured figures rather than to an application, because there is nothing to wait for.
We survey the roof, establish what it can carry and what is genuinely usable once rooflights, plant and shading are removed, and model generation against your half hourly consumption. That gives a capital cost, a split between electricity you displace and electricity you export, and a payback you can defend to a board. The roof survey is free and it is the document you keep, whoever ends up installing.
From there the funding conversation is about routes rather than awards: capital purchase against asset finance or a green business loan, an operating lease or a power purchase agreement, each with a different answer on who claims the allowances and who keeps the export income. For a company with a net zero commitment or a customer asking about carbon in its supply chain, the array is usually the largest single reduction in carbon emissions available on the site, larger than energy efficient lighting and controls put together, and it is worth reporting properly whether or not anyone funds it. A net zero target with no on site generation behind it is a target, not a plan. Yields and network operators vary by region, and the figures for your area are on our locations pages.
Lenzie Consulting Ltd arranges the survey, the design and the installation through our MCS-certified partner. We are not authorised or regulated by the Financial Conduct Authority and we do not give financial, tax or legal advice. Finance introductions are to unregulated business lending. Companies should take their own tax and legal advice before committing.

Questions about solar grants for business
- Am I eligible for a solar grant?
- Eligibility for a solar grant in the UK is narrow, and almost no private company falls inside it, if by grant you mean public money towards panels on a commercial building. No UK scheme currently pays a trading company a capital contribution for putting solar panels on its warehouse, factory or office. The schemes that do award grants are either sector specific or public sector: the Public Sector Decarbonisation Scheme delivered by Salix Finance funds public bodies in England, Farming in Protected Landscapes funds farmers and land managers inside National Parks and National Landscapes, and the Industrial Energy Transformation Fund is aimed at industrial process energy use rather than at building services. If you are a private company in a distribution warehouse you fall outside all of them. What you get instead is capital allowances, VAT recovery and export income, which between them are worth more than most of the grants people go looking for.
- Can you get a government grant for a small business?
- Government grants for a small business do exist, but very few of them pay for solar panels. The Boiler Upgrade Scheme covers heat pumps in small non domestic buildings in England and Wales, not solar PV; gov.uk sets out the Boiler Upgrade Scheme rules, checked September 2026. The Workplace Charging Scheme covers EV chargepoint sockets, not generation. Beyond those, support for a small business is mostly advice, business support services and lending rather than capital business grants. The reliable place to look is the gov.uk tool find funding to help your business become greener, checked September 2026, which filters by nation, sector and size and is kept current in a way that commercial grant pages are not. Your local growth hub can tell you what is open near you.
- Can my business pay for solar panels?
- A business can pay for solar panels in four ways: a capital purchase, asset finance or hire purchase, an operating lease, or a power purchase agreement. A capital purchase buys the array outright from cash reserves and the company claims the capital allowances. Hire purchase is a form of asset finance in which a funder buys the array, you repay over a term, and title passes to you at the end. An operating lease is an agreement under which the funder owns the array and you pay a rental for its use. A power purchase agreement is a contract under which a funder owns the array and sells you the energy it generates, with no capital from you at all. Business lending of this kind is generally unregulated business lending, so the consumer credit protections do not apply. The routes are compared on our finance and PPA page.
- Are solar panels worth it for a business?
- Solar panels are worth it for a business when the building consumes most of what the roof generates during daylight hours. That single proportion decides the case rather than the size of the roof, because a unit you consume displaces the full price you pay to import, while a unit you export earns a much lower rate. A warehouse running lifts, chillers, compressors or charging through the working day converts a high share of what the roof makes and the case is usually strong. A building that is dark at weekends and quiet in the afternoon exports heavily and the case is weaker. That is why we model half hourly consumption against modelled generation before quoting, and why we say so when the answer is no.
- Can I claim solar panels as a business expense in the UK?
- A rooftop array is capital expenditure rather than a revenue expense, so it is claimed through the capital allowances regime rather than written off in one line in the profit and loss account. The special rate pool is the capital allowances pool for integral features of a building, HMRC treats solar panels as integral features, and it sets that out in its Capital Allowances Manual at CA22335, checked September 2026. Whether you can cover the spend with the Annual Investment Allowance in the year you buy depends on the limit and on what else the company has spent. Maintenance, cleaning and monitoring contracts after commissioning are ordinary running costs. Ask your accountant, because the answer depends on your company rather than on the equipment.
- Is there VAT relief on solar panels for a commercial building?
- The zero rate for energy saving materials applies to installations in residential accommodation and in buildings used for a relevant charitable purpose. HMRC sets out the conditions in VAT Notice 708/6, checked September 2026. A commercial warehouse is neither, so the installation carries VAT at the standard rate. If the business is VAT registered and makes taxable supplies, that VAT is recovered as input tax in the normal way, which for most companies makes it a cash flow point rather than a cost. Charities and mixed use buildings need to check the notice carefully, because partial relief can apply.
- Can a school or an NHS trust get funding for solar?
- Public sector bodies in England can apply to the Public Sector Decarbonisation Scheme, which Salix Finance delivers on behalf of central government. The scheme runs in phases with published windows and criteria, it is competitive, and it has historically been weighted towards heat decarbonisation with associated measures rather than towards solar on its own. Applications need a costed scheme and a delivery timetable, which is what the survey and design work produces. Check the open phase and the current criteria at salixfinance.co.uk before you plan around it.
- Do I need an MCS certificate to claim the Smart Export Guarantee?
- The Smart Export Guarantee requires the installation to be certified under the Microgeneration Certification Scheme or an equivalent, alongside a generation capacity up to 5MW and a meter capable of providing half hourly export readings. Those are Ofgem's published conditions. Suppliers set their own tariffs, so the rate you are offered is a commercial matter between you and the supplier rather than a fixed government figure. We arrange the survey, design and installation through our MCS-certified partner, which is what produces the certificate the supplier will ask for.
