Solar Panels for Farms & Agricultural Buildings
MCS-certified solar installation for UK farms. The FETF closed in April 2026 — England's live capital route is the Improving Farm Productivity grant at 25%. Class R permitted development covers most farm buildings. Free farm feasibility survey.
Quick Answer
Can UK farmers get grants for solar panels, and how much do they cost?
Yes — England's live capital route is the Improving Farm Productivity (IFP) grant, contributing 25% of eligible project costs where solar powers farm operations. (The old FETF closed its final round on 28 April 2026 — and it was a fixed-rate equipment fund, never a percentage solar grant.) Across the UK, support runs 25–40% depending on nation and scheme. A typical 50kWp farm system costs £37,000–£50,000 before support. Most agricultural buildings qualify under Class R permitted development — no planning permission required. The Annual Investment Allowance provides 100% Year 1 tax relief, which on its own brings typical payback to 2–4 years.
Why UK Farmers Are Installing Solar in 2026
UK farms face sustained pressure on margins — energy is one of the few controllable costs. Agricultural electricity tariffs averaged 28–34p/kWh in 2026, with some farmers on farm-specific business tariffs paying 30–38p/kWh. A single dairy farm with 300 cows can spend £45,000–£80,000 per year on electricity for milking, water heating, refrigeration, and ventilation. Solar directly offsets this — with daytime generation closely matching morning and evening milking periods.
England's farm-grant landscape changed in 2026: the Farming Equipment and Technology Fund (FETF) closed its final round on 28 April 2026 — and contrary to much of what is still published online, it was a fixed-rate equipment fund, never a percentage capital grant for solar. The live capital route is now the Improving Farm Productivity (IFP) grant at 25% of eligible costs. Combined with 100% first-year AIA tax relief, Class R permitted development rights (eliminating the need for planning permission on most farm buildings) and 25-year panel warranties, the case for farm solar remains strong.

Farm Solar Grants in 2026 — What Changed, and What's Live
What changed: the Farming Equipment and Technology Fund (FETF) closed its final application round on 28 April 2026. It was a fixed-rate equipment fund — set payments against approved kit items worth roughly £1,000–£25,000 — and was never a percentage capital grant for solar, despite widespread copy still claiming a "FETF 25% solar grant".
England's live capital route is the Improving Farm Productivity (IFP) grant, administered by the Rural Payments Agency (RPA) under the Farming Investment Fund. It contributes 25% of eligible capital costs for productivity-boosting investments, including solar where it powers farm operations.
Key eligibility points for farm solar under IFP:
- You must be a registered farm business in England
- The solar system must primarily serve an agricultural purpose (powering farm buildings, milking equipment, grain drying, etc.) — not primarily commercial generation
- Applications open in competitive funding rounds — check the current RPA guidance before committing
- Scotland, Wales and Northern Ireland run separate schemes; across the UK, support typically runs 25–40% depending on nation and scheme
Whatever the grant position, the Annual Investment Allowance (100% first-year tax deduction) applies UK-wide — with AIA alone, typical farm solar payback is 2–4 years. We can advise on current funding availability and help structure your application.
Farm Solar System Sizing by Type
| Farm Type | Annual Electricity Use | Recommended System | Annual Saving* | Post-Grant Cost |
|---|---|---|---|---|
| Dairy Farm (200 cows) | 120,000–180,000 kWh | 50–80kWp | £13,500–£22,000 | £28k–£55k |
| Dairy Farm (500+ cows) | 250,000–400,000 kWh | 100–200kWp | £27,000–£54,000 | £54k–£131k |
| Poultry (50,000 birds) | 300,000–500,000 kWh | 100–250kWp | £27,000–£67,500 | £54k–£164k |
| Pig Farm (500 sows) | 200,000–350,000 kWh | 75–150kWp | £20,000–£40,000 | £41k–£98k |
| Arable (grain drying) | 80,000–200,000 kWh | 30–100kWp | £8,100–£27,000 | £17k–£71k |
| Mixed Farm | 100,000–250,000 kWh | 40–100kWp | £10,800–£27,000 | £23k–£71k |
* Annual saving at 30p/kWh with 75% self-consumption. Post-grant cost assumes a 25% capital grant received (IFP in England, or national equivalent).
Class R Permitted Development for Farm Solar
Class R of the Town and Country Planning (General Permitted Development) Order 2015 allows certain changes of use and installations on agricultural land and buildings without requiring full planning permission. For solar panels on agricultural buildings, most installations qualify as permitted development subject to the following conditions:
- The solar panels are installed on an agricultural building, not on open land
- The agricultural unit is at least 5 hectares
- The system capacity does not exceed 1MWp
- The installation does not involve significant engineering works to the building
- The building is not listed or in a World Heritage Site
For installations on agricultural land (ground-mounted), rather than on buildings, different Class R rules apply with tighter size restrictions. We advise on permitted development eligibility for every project — where PD rights don't apply, we manage the full planning application process.
Farm Building Roof Types
Portal Frame Buildings (Fibre Cement / Tin Roofs)
The majority of UK farm buildings are steel portal frames with profiled metal or fibre cement sheet roofing. These are ideal for solar installation — clamp-mounted systems require no roof penetrations and can be installed quickly. Fibre cement (non-asbestos) roofing is the most common substrate and presents no specialist requirements.
Older Asbestos Cement (AC) Roofing
Many older farm buildings have asbestos cement sheet roofing. This is common on pre-1980 buildings and is not hazardous if undisturbed, but requires specialist handling for any penetration or attachment work. We can install solar systems on AC roofs using carefully designed clamp systems that avoid drilling — or advise on overcladding (installing new metal sheeting over the existing AC) which resolves both the asbestos and solar opportunity simultaneously.
Grain Store Flat Roofs
Modern grain stores often have flat or shallow-pitch polymer membrane roofs. These suit ballasted solar systems (no penetrations) and can accommodate larger system sizes per square metre of usable roof area than pitched roofs.
Agricultural Energy Profiles: Getting Solar Right by Farm Type
Dairy Farms
Dairy farms are the best-matched farm type for solar due to their consumption profile. Milking twice daily (6–8am and 4–6pm) aligns with solar generation in summer months. Additional loads include milk refrigeration (24/7), hot water for cleaning (morning and evening peaks), and parlour lighting. Typical dairy farm self-consumption rates: 70–85% — among the highest of any agricultural sector.
Poultry Houses
Modern poultry houses are substantial electricity consumers: ventilation fans, lighting programmes, heating during chick rearing, and automated feeding systems. Poultry houses run 24/7 during production cycles, making battery storage complementary to maximise solar use overnight. Large poultry sites with multiple houses often justify 200–500kWp+ systems.
Arable Farming
Arable farms have seasonal electricity demand peaks: grain drying in harvest (August–October) coincides with high solar generation in summer/early autumn, making alignment excellent. Outside harvest, electricity use is lower — battery storage can maximise solar value during low-demand periods.
Pig Farms
Pig buildings use electricity for ventilation, lighting, electric hoists, pressure washing, and heating for weaner accommodation. Load profiles are relatively consistent year-round. Solar offsets base load effectively, with typical self-consumption of 65–75%.
Smart Export Guarantee (SEG) for Farms
Any solar electricity you don't consume on-farm can be exported to the grid under the Smart Export Guarantee (SEG). SEG rates from Octopus Energy, E.ON, and others range from 4–20p/kWh. For farms with summer solar surplus (arable farms during pre-harvest periods), SEG provides meaningful additional revenue of £1,500–£8,000/year depending on export volume and chosen tariff.
To qualify for SEG, your system must be under 5MWp, MCS-certified, and have an export meter installed (included in our standard farm installation). We assist with SEG tariff comparison and registration.
Case Study: 210kWp Dairy Farm, Cumbria
A representative profile for a 300-cow dairy farm: a 210kWp system across three farm buildings. Pre-solar electricity spend: £56,000/year. The system generates 186,000 kWh/year, with 83% self-consumed during milking and dairy operations. Annual electricity saving: £46,300. With a 25% capital grant, net project cost falls to around £138,000, giving a payback of roughly 3 years — before AIA tax relief improves it further.
Case study: 210kWp dairy farm solar — results after 18 months → real generation, savings and payback from a working farm install.
Agricultural Solar Panels Across the West Midlands, County by County
The West Midlands is one of England's most productive farming regions, and the spread of agricultural solar panel installation across the West Midlands reflects how varied that farming is. In Shropshire, large dairy and mixed holdings around Shrewsbury, Market Drayton, Whitchurch and Oswestry run portal-frame buildings with thousands of square metres of south-facing roof — ideal for 100–250kWp installs feeding milking parlours, bulk tanks and grain dryers. The county is also home to Harper Adams University at Edgmond, near Newport, keeping agricultural energy innovation visible locally.
Herefordshire is the engine of UK poultry — the broiler and free-range egg units around Hereford, Leominster, Bromyard and Ross-on-Wye are heavy, year-round electricity consumers (ventilation, lighting programmes, chick heating), where solar paired with battery storage can lift self-consumption well above 70%. Cider-apple orchards and hop yards around Ledbury add cold-store and pumping loads that match summer generation neatly. In Worcestershire, the horticultural Vale of Evesham — Evesham, Pershore and Badsey — runs glasshouses, pack-houses and refrigeration that draw power through the day, a near-perfect solar profile. Staffordshire dairy farms across the Moorlands, around Leek, Cheadle and Uttoxeter, and the arable and mixed units of Warwickshire near Stratford-upon-Avon and Southam, complete the picture.
Every grid connection across these counties goes through NGED (National Grid Electricity Distribution, formerly Western Power Distribution) as the West Midlands DNO. Systems above 50kWp that export need G99 approval (about 65 working days); smaller units fall under G98. With the Midlands averaging around 950 kWh per kWp, a 100kWp West Midlands farm system generates roughly 95,000 kWh a year and typically pays back in 4–7 years — or 3–4.5 years once the FETF 25% grant and AIA first-year tax relief are applied.

Frequently Asked Questions
Is the FETF solar grant still open?
No — the FETF (Farming Equipment and Technology Fund) closed its final round on 28 April 2026, and it was a fixed-rate equipment fund rather than a percentage solar grant. England’s live capital route is the Improving Farm Productivity (IFP) grant at 25% of eligible costs. Scotland, Wales, and Northern Ireland run separate schemes — across the UK, support is typically 25–40% depending on nation and scheme. We can advise on your specific eligibility.
Do farm solar panels need planning permission?
Most farm solar installations qualify under Class R permitted development rights, meaning no planning permission is required. This applies where the agricultural unit is over 5 hectares, the system is on an agricultural building (not open land), and the system is under 1MWp. Ground-mounted systems on agricultural land have tighter rules. Listed buildings and World Heritage Sites always require full planning consent. We carry out a PD assessment as part of every farm project.
How much roof space does a farm solar system need?
A rule of thumb: 1kWp requires approximately 6–7m² of south-facing roof area (or 7–9m² for east-west systems). A 50kWp system needs approximately 350m² of roof area; a 200kWp system needs approximately 1,400m². Most portal-frame farm buildings have roof areas of 500–3,000m², easily accommodating 50–500kWp systems.
Can farm solar panels power the whole farm?
A well-sized farm solar system can generate 40–80% of the farm's annual electricity needs, with the remainder drawn from the grid during night-time or low-generation periods. Adding battery storage can increase solar self-supply to 80–95%. However, most farms find the economics of solar-only (without battery) highly attractive — it's not necessary to meet 100% of consumption for excellent ROI.
What happens to farm solar if you sell the farm?
Farm solar systems are installed as fixtures to the building and transfer with the property on sale. A well-documented system with a proven financial track record (energy savings, SEG income) typically adds value to a farm sale. We provide full documentation (MCS certificates, G99 approval, warranty documentation) suitable for property transfer.
