Leasing Land for a Solar Farm: A UK Landowner's Guide

Updated 8 October 2026 · SEO Dons Editorial

This guide is for landowners who have had a letter from a solar developer, or who are wondering whether their land could earn a solar rent. It sets out what developers look for, how a typical UK deal is structured from first approach to decommissioning, what rents land agents have published, and the tax and tenancy points that catch people out. It is published by SEO Dons Ltd as independent information. SEO Dons does not broker land deals or act for landowners; take independent advice from a land agent and a solicitor before you sign anything, including heads of terms.

What solar developers look for in a site

A developer is buying the chance to connect a power station to the grid. Rent levels and interest from developers follow grid capacity more than anything else, so the first question is rarely about the soil.

Grid connection. Carter Jonas has said viable sites are generally within about 5km of a substation or have suitable overhead lines nearby. Farmers Weekly reported land agents warning as far back as 2015 that grid capacity was the main limit on which sites could go ahead, and that remains the first filter.
Size. Modern ground-mounted schemes are large. Farmers Weekly reported in July 2024 that a 50MW scheme needs roughly 100 hectares, against 10 to 12 hectares for the 5MW farms of the 2010 boom. Carter Jonas has suggested 80 acres and above is viable, though some developers do take smaller parcels.
Land quality. Government policy steers large solar away from the best and most versatile (BMV) land, which is Grade 1, 2 and 3a under the Agricultural Land Classification. A Written Ministerial Statement of 15 May 2024 said large schemes should avoid BMV land where possible. Our guide to agricultural land classification for solar explains how grading works and how to check yours.
Topography and aspect. Flat or gently south-facing fields with few shading features, outside flood zones, are easier to design and consent.
Access and constraints. Developers check road access for construction traffic, rights of way, heritage and landscape designations, and how visible the site will be from homes and roads.

Size also decides the consenting route. In England, the Electricity Act 1989 (Requirement of Consent for Solar Generating Stations) (England) Order 2025 raised the threshold for solar from 50MW to 100MW from 31 December 2025. Schemes below 100MW now go through the local planning authority rather than the Secretary of State, which matters for timescale and for how a landowner can follow the application.

How a solar land deal is structured, stage by stage

Almost every UK solar land deal follows the same shape: heads of terms, then an option agreement, then a long lease once the developer has planning permission and a grid offer. The table below summarises each stage and what to watch.

Stage	What happens	Typical length	Points to negotiate
Approach and heads of terms	Developer offers headline terms: rent, option fee, term, area	Weeks to months	Not usually legally binding, but hard to move away from once signed. Get advice first. Ask who pays your professional fees.
Exclusivity and option agreement	Developer gets the exclusive right to seek planning, grid and other consents and to call for the lease	Often 3 to 5 years; Brown & Co has cited 3 to 15 years	Option fee, extension fees if planning or grid is delayed, a longstop date, which land is included, what you can still do with it
Planning and grid	Surveys, planning application, grid connection agreement	Months to years	Access for surveys, crop compensation, your right to see and comment on the application
Lease granted and construction	Option exercised, lease completed, site built	Construction usually months	Rent or a fee during construction, reinstatement of damage, working hours, gates and fencing
Operation	Rent paid; grazing may continue under licence	Commonly 25 to 40 years; some 40-plus	Indexation, revenue-share top-up, rent reviews, grazing rights, repair of drains and boundaries
Decommissioning	Panels, frames, cables and fencing removed; land restored	End of lease or early break	A decommissioning bond or other security in place and accessible, reviewed during the term

Option agreements and exclusivity

The option is the part most landowners underestimate. Trowers & Hamlins describes option periods of anywhere from 1 to 10 years; HCR Law says three to five years, sometimes longer, often extendable for a further fee if planning or the grid connection is delayed. During that time the land is tied up: you generally cannot talk to another developer, and you may need consent for things that would affect the scheme. Ask for a firm longstop date, an annual fee for each extension, and a clear plan of the option land so the whole farm is not caught.

Lease length, indexation and revenue share

Once the option is exercised, the lease sets the term and the rent. Trowers & Hamlins and HCR Law both put typical solar lease terms at 25 to 40 years; Farmers Weekly reported 40-plus years being typical for large schemes in 2024. Rent may be fixed per acre, per megawatt, a share of revenue, or a mixture. Index-linking is the norm. A revenue-share top-up, where you receive a percentage of the scheme's income if that beats the base rent, is worth asking for: Fisher German was quoted in 2024 citing 5 to 6% of site turnover, and Stephens Scown has referred to top-ups of 4 to 6%.

Decommissioning and bonds

The lease should oblige the developer to remove everything and restore the land. The risk is that the operator in year 35 is not the company you signed with, and may not have the money. Strutt & Parker has advised that reinstatement cannot be left to the goodwill of the developer, and that landowners should settle when the security is put in place, whether it is cash or a bond, who can draw on it, and how often the amount is reassessed. HCR Law adds that the security should also cover any ongoing biodiversity net gain obligations tied to the land.

How much do solar farms pay per acre in the UK?

Published figures from UK land agents and law firms cluster around £1,000 per acre per year for the base rent, index-linked. The ranges below are what each source said at the time; they are not offers, and individual sites can fall well outside them.

Source	Date	What they said
Fisher German, quoted in Farmers Weekly	July 2024	Up to £3,000/ha (about £1,200/acre), index-linked, plus a 5 to 6% revenue share in some deals
Brown & Co	June 2024	Around £1,000 per acre, index-linked, on leases that can run 40 years
Stephens Scown	Reviewed September 2023	Subsidy-free solar rents of £850 to £1,100 per acre per year, depending on size and location
Savills Research	November 2022	Industry commonly quotes £2,500/ha; Savills calculated the true margin over farming nearer £2,100/ha
Carter Jonas, in Farmers Weekly	June 2020	In excess of £800/acre and can be £1,000/acre

What moves a site up or down that range: distance to a substation with spare capacity, the size of the scheme, how many developers are competing, and whether a revenue share is included. Battery storage on part of the land is priced very differently. Brown & Co quoted starting rents of £20,000 to £50,000 per acre for battery and synchronous condenser sites in 2024, though those need only a small footprint and a strong grid point.

Illustrative example, not a real deal: 100 acres let at £1,000 per acre would produce a base rent of £100,000 a year before income tax, rising with whatever index the lease uses. Over a long term that is many times what the same land would earn in arable or grazing rent, which is why developers can afford to tie up land for years before building. Set that against the tax points below, the option years when you receive only an option fee, and the risk the scheme is never built.

Tax: income tax, inheritance tax and capital gains

Income tax

Solar rent is generally taxed as property income rather than farming profit, at your marginal rate (or within a company, if the land is owned that way). From April 2027 the government plans separate income tax rates for property income in England, Wales and Northern Ireland, 2 percentage points above the standard rates, which would apply to solar rent received by individuals. Your accountant should model the rent alongside your existing income before you agree terms, because the rent alone may push you into a higher band for decades.

Agricultural Property Relief

This is the point that most often changes the decision. Agricultural Property Relief (APR) from inheritance tax depends on the land being occupied for agriculture. Savills Research and agricultural tax advisers have consistently said that land let to a solar operator is no longer in agricultural occupation, so APR on that land is lost. Grazing sheep under the panels does not restore it, because the occupier is the solar company, not the farmer. Since 6 April 2025, APR has been extended to land managed under environmental land management agreements, such as SFI and Countryside Stewardship, but that extension does not cover land let for solar.

From 6 April 2026, the government has changed how APR and Business Property Relief (BPR) work. According to gov.uk, a combined £2.5 million allowance applies to property qualifying for 100% APR or BPR, relief above that is at 50%, and any unused allowance can pass to a surviving spouse or civil partner. That allowance only helps with property that qualifies for relief in the first place, so it does not bring solar-let land back into APR.

Business Property Relief

Some landowners hope to claim BPR on the solar land as part of a wider farming business, relying on the Balfour case. Tax advisers have warned that this is not dependable where the solar rent is large compared with farming income, and that where relief is available it may only be at 50%. Some advisers suggest term life cover sized to the potential inheritance tax for the lease period. This is specialist ground: get advice from a rural tax adviser before you sign the option, not after.

Capital gains

Granting a long lease, receiving option fees and later selling land that carries a solar lease all have capital gains tax consequences, and a solar lease affects how the land is valued. HCR Law flags capital gains and income tax as points to settle with advisers before committing.

Tenanted land: AHA and farm business tenancies

If the land is let to a farmer, the tenant's rights come first. Under an Agricultural Holdings Act 1986 tenancy, a landlord who wants land back for solar normally needs planning permission before serving a Case B notice to quit, on the ground that the land is required for a non-agricultural use. Roythornes notes that the court in Floyer-Acland v Osmond suggested Case B allows for more than one use, so a requirement to keep grazing under the panels is unlikely on its own to defeat a notice. Tenants can still object to the planning application, and a tenant can refer the notice to arbitration, which can delay a scheme.

For a farm business tenancy under the Agricultural Tenancies Act 1995, what you can do depends on the tenancy agreement: whether there is a break clause, what notice is needed, and how much land can be resumed. Developers will want vacant possession of the option land, so check the tenancy before you sign heads of terms, and speak to your tenant early. HCR Law also advises checking how a project interacts with existing tenancies and with any environmental land management agreements, because entering a renewables agreement could disqualify you from some scheme payments or create clawback liabilities.

Environmental schemes and grazing under panels

The Sustainable Farming Incentive closed to new applicants on 11 March 2025. It reopened as SFI26 in 2026, with application windows from 30 June and 22 September 2026, and Defra has said it plans to offer an SFI scheme in 2027. SFI does not pay for solar panels. The SFI26 rules say you must have management control of the land in your agreement for the whole duration of the actions you choose, and that if you lease land to someone else during the agreement you no longer have management control of it. So land you let for solar is likely to need to come out of any agreement, and you must tell the Rural Payments Agency in writing. Check the current rules with the RPA before you sign, and ask your adviser about any clawback.

Grazing usually can continue. Stephens Scown notes that solar farms are generally built so the land can be grazed, mainly by sheep or poultry, and Trowers & Hamlins says landowners often reserve sheep grazing rights in the lease. Agree in writing who maintains the sward, fencing and water, and whether the developer pays you or you pay them for the grazing. If you are interested in genuinely combining crops and panels, see our page on agrivoltaics; that is a different design from a standard solar farm. For how grazing fits wider livestock systems, see our livestock farms page.

Checklist before you sign anything

Appoint your own land agent and solicitor, independent of the developer, before signing heads of terms. Ask whether the developer will contribute to your professional fees.
Check who you are dealing with. Is the company a long-term owner-operator, a funded developer, or a site finder who will sell the project on? Farmers Weekly has highlighted these differing risk profiles. Ask for accounts, a parent company guarantee, and track record.
Control assignment. The lease will almost certainly be assignable. Make sure any incoming operator takes on all obligations, including decommissioning security.
Limit the option. A defined plan, a longstop date, a fee for every extension, and a clear list of what you can still do with the land.
Secure decommissioning. Bond or cash security in place before the tenant can break, with a regular reassessment of the amount.
Map cables and easements. Cable routes, access roads and substations may cross land outside the lease area. Agree routes, depths, compensation and reinstatement of drains, and do not grant rights over land you might want to develop.
Do not sign away your grid connection. Strutt & Parker's advice, quoted in Farmers Weekly: take advice before agreeing anything that commits your grid capacity.
Model the tax, including loss of APR on the let land and the effect on succession plans, with a rural tax adviser.
Clear tenancies and schemes: AHA or FBT tenants, SFI or Countryside Stewardship agreements, and any lender's consent if the land is mortgaged.

If you would rather use the electricity on the farm than let the land, compare the alternatives in our guides to solar panels on farmland and whether solar is worth it for farms. Grants and allowances for self-owned systems are covered in grants and funding.

Frequently asked questions

Is a letter from a solar developer a sign my land is valuable?

It usually means a developer has spotted possible grid capacity near you and is screening many sites. Several developers may write to the same area. Do not sign anything on the strength of the letter; ask a land agent whether the site is likely to attract competing interest and what terms comparable sites have secured.

Do I get paid if the solar farm never gets built?

During the option period you normally receive only the option fee and any extension fees, not the full rent. If planning or the grid connection fails, the developer can usually walk away when the option ends. That is why a longstop date and fees for each extension matter.

Can I still farm the land under the panels?

Sheep grazing is common and is often reserved in the lease. Arable cropping is not possible under a standard layout. Grazing does not restore Agricultural Property Relief on the let land, because the solar company is the occupier.

Who pays my legal and land agent fees?

This is a point to negotiate at heads of terms stage. Ask whether the developer will contribute to your reasonable professional costs for the option and the lease, and get any agreement in writing before instructing advisers.

Can I sell the farm with a solar lease in place?

Yes, the land can be sold subject to the lease, and the buyer takes on the rent and the developer's rights. A long solar lease affects how the land is valued and taxed, so take valuation and tax advice before you sell or pass the land on.
