For many UK businesses, investing in solar power is not only an environmental imperative but also an economic one. With the cost of energy rising and with growing pressure to achieve sustainability goals, solar panels are an intelligent long-term solution. Still, the initial outlay can prove costly.
Fortunately, various government incentives and grants have been provided to fund commercial solar panel installations. Knowledge of these schemes can enable your business to make an assured and economically responsible transition to renewable power.
Below, we explore the most relevant UK government grants for solar panels for different industries, and how Noble Green Energy can help your business access them efficiently.
Solar Panel Grants for Businesses
Did you know that the UK government has almost £5 billion of funding available to help businesses become greener? As part of their commitment to reach net zero emission by 2050, their portal provides access to national funding streams and what schemes are currently available to be applied for.
Capital Allowances
The Annual Investment Allowance (AIA) allows businesses investing in plant and machinery to claim tax relief of 100% on qualifying capital investment, such as solar panels, of up to £1 million each year. This can save your corporation tax bill substantially in the year you make the purchase and you can take advantage of this by ensuring your investment is timed effectively in your year of taxation.
Another option is First Year Allowances (FYA) which allows businesses to claim tax relief of 50% on special-rate assets, including long-life assets such as solar panels.
Smart Export Guarantee (SEG)
The SEG is an initiative backed by the government which enables firms to make money from selling unused electricity back into the grid. When your company installs solar PV panels with capacity of up to 5MW, the SEG guarantees you are paid for each kilowatt-hour (kWh) you export which can typically be £0.03-0.05 per exported kWh. SEG rates are different with each supplier, so comparing them is critical to achieve the highest returns.
Local Growth Hub Solar Grants
It’s a good idea to research your business’ local growth hub solar grants as many Combined Authorities and Local Enterprise Partnerships operate helpful schemes. Some can offer up to 30% capital grants towards the purchase and installation of rooftop solar PV for local businesses.
For example, the West of England Growth Hub has run a “Rooftop Solar Grants” programme for those with a generation capacity of at least 50kWp DC within a single array and an inverter output of at least 40kW AC. You can find your Local Business Growth Hub here.
Solar Panel Grants for Farms
There are new UK government solar panel grants available for arable, horticulture and livestock farms coming out all the time. It’s important to keep an eye on available opportunities for your agricultural business. Some current examples of these include:
Improving Farm Productivity (IFP) Grant
This Department for Environment, Food & Rural Affairs (DEFRA)-run grant offers 25% capital support specifically for solar PV equipment on farm rooftops or reservoirs. It is currently on round 2 and provides a minimum grant of £15,000 or maximum £100,000 per applicant.
Farming Equipment & Technology Fund (FETF)
FETF grants will be on the smaller side, between £1,000-£25,000, but a total of £30 million will be available. They have been introduced to support technology that will boost productivity and environmental performance on farms. Some rounds will explicitly include solar PV systems, so make sure to be aware of new rounds announced.
Solar Panels for the Public Sector
Local Partnerships help improve the carbon and energy performance of the public sector by retrofitting workplaces, schools, hospitals and more with energy efficient infrastructure. You can find out more and apply for improvements here or see more grants available below.
Public Sector Decarbonisation Scheme (PSDS)
The PSDS provides funding to public sector organisations for energy efficiency measures, including solar installations. Schools, NHS trusts, councils, and emergency services can access significant grants through this scheme.
This is a competitive funding process with strict timelines and the Public Sector Low Carbon Skills Fund runs alongside PSDS to help bodies develop decarbonisation plans.
Clean Energy Investment
On 15th May 2025, the UK government announced a £630 million clean energy investment was available for public buildings to upgrade with solar panels and heat pumps. It has been introduced to save around £650 million a year on average on energy costs which will consequently help curb carbon emissions for the country.
How to Apply for Government Grants for Solar Panels
Now you know where to find all the UK government grants and schemes, you need to make sure you choose the right one for you and your business. From there, you can look into the individual grants and check the eligibility criteria and application windows. Some of them will run indefinitely whereas others will only be available in phases.
Regarding the criteria, some may require quotes from MCS-registered installers which will factor in any grid connection or roof-strengthening costs. As well as this, you will usually need an EPC, project plans, full cost breakdown and evidence of financial standing.
Grants aside, we recognise many businesses require accessible financing models to install solar panels. Some of our customers have used financial solutions such as Power Purchase Agreements (PPA), Asset Finance and Hire Finance to help them achieve their goals.
