Solar Lease Risks for Farmers: What to Check Before You Sign Anything
I spent a few of my childhood holidays on a farm — mum would do anything to get us out the house. My auntie owned and ran it, and I was up before anyone wanted me up, getting in the way more than helping — but learning how a working farm actually runs underneath the bit you see from the road. That's the lens I bring to this, not a spreadsheet in a boardroom. We've had dirt under our nails helping plant trees on a friend's farm to offset our own carbon footprint. We get it.
Farmers being approached over solar, battery storage and wind schemes are being urged to check the small print before they sign — that's the warning currently circulating from rural solicitors, and it's the right warning. Pepperells Solicitors' head of rural, Simon Rounding, has pointed out that once heads of terms are signed, a farmer's options are much more limited — the time to make the deal work is before pen touches paper. At Independent Solar Consultants (ISC), we agree with the warning. We just think it starts one step too late. FarmingUK
The legal risk is real. But by the time a solicitor is reviewing a contract, the technical and commercial decisions — site suitability, scale, grid connection, whether battery storage is even sensible on that land — have usually already been made informally, in conversation with the developer who wrote the offer. That's the gap most coverage misses.
What's Being Claimed, and What It Ignores
The current wave of warnings is consistent: decommissioning costs, tax exposure, easements, and the pressure to sign quickly. Legal experts warn that without watertight decommissioning terms, farmers could be left paying for specialist equipment removal and land restoration themselves, with solar leases sometimes running 40 to 50 years. Separately, capital gains and inheritance tax implications, and the risk of losing agricultural tax reliefs, are flagged as part of the same picture. FarmingUKFarmingUK
What's consistently left out: who assesses whether the scheme makes technical sense in the first place. A developer proposing a lease has every incentive to make the numbers look attractive and the process feel straightforward. Few farmers have access to someone with no stake in the deal who can say plainly whether the connection capacity, the site layout, or the proposed scale actually works — before legal terms are even on the table.
What the Market Is Missing
Coverage treats this almost entirely as a contract problem. It isn't only that. A landowner signing a 30 to 40 year agreement is, in practical terms, becoming a sophisticated commercial landlord overnight — taking on liability, environmental exposure and tax complexity they've never had to manage before. That shift in risk profile deserves more scrutiny than "get a solicitor." Farm Progress
It also ignores the commercial upside being left on the table through poor negotiating position. A guaranteed rent of £600 per acre can sound generous next to a typical farm business tenancy of £150-200 per acre — but many solar rentals being agreed across the market are closer to £950 per acre, plus additional payment where battery storage is added. Developers also frequently reserve the right to install battery systems later, which means landowners need protection against losing out if that happens after signing. A farmer negotiating from the first offer they receive, without independent benchmarking, is very likely leaving money on the table as well as taking on undisclosed risk.

What Experience Shows
I think about my auntie's farm a lot when this subject comes up, because it taught me early that a farm is never just the bit a deal is about. You sign something affecting one field, and it touches the yard, the access track, the shed, the rhythm of the whole place. Developers writing a lease offer rarely see it that way. They see acreage.
That's carried through into the actual work we do. We've worked across a range of farm sites where solar, battery, and grid questions all came up before any lease was on the table — and the pattern is consistent. Long, thin agricultural sheds — the kind common on poultry sites — are often genuinely well suited to solar, partly because of how they're oriented and partly because keeping muck and dust off panels and inverters is a manageable, known maintenance task rather than an unknown one. What gets missed almost every time is that maintenance: panels and inverters lose performance fast without it, and warranty terms can be voided if upkeep isn't documented. That's the kind of detail nobody mentions in a glossy lease pack, because it's not the developer's problem once the rent's being paid — it's yours.
We've also carried out energy audits on farms with existing wind turbines where the owner wanted to add battery storage — assessing whether the existing connection and turbine output actually supported it before any commercial conversation started. And we've looked at solar for sites with genuine cooling loads: potato stores, grain stores, and farm shops facing rising energy costs, where the real question wasn't "should we lease land for a solar farm" but "does on-site generation actually solve the cost problem we have."
In nearly every case, the starting point that mattered most was the grid connection — a DNO application early, before commercial terms are negotiated, tells you what's actually possible on that site. Skip that step, and every other number in the lease is built on an assumption. My auntie would never have signed anything without walking the field herself first. I think that instinct was right long before I understood the engineering behind it.
The Commercial Logic
This isn't an argument against solar leases. It's an argument for sequencing the decision properly.
| Factor | Typical Approach | ISC Approach |
|---|---|---|
| Order of advice | Legal review after heads of terms are drafted | Technical and grid feasibility assessed before any terms are discussed |
| Rent benchmarking | Accept the first offer as the market rate | Compare against current independent market data before negotiating |
| Battery clauses | Treated as a future add-on, often unprotected | Assessed and priced into terms from day one |
| Decommissioning | A bond set once, rarely revisited | Reviewed against realistic long-term removal and restoration cost |
None of this replaces a solicitor. It gives the solicitor something solid to work with, instead of a contract built on assumptions nobody checked.
Global Context
This isn't a UK-only pattern. In the US, attorneys working with agricultural landowners describe an industry "created out of thin air" in the last few years, without the established channels that protect farmers in better-understood transactions, and are actively warning landowners not to sign without independent counsel. The shape of the risk — fast-moving developers, slow-moving legal protection, farmers caught in between — is showing up wherever solar diversification is growing quickly, not just here. Farm Progress
The Right Questions
The right starting point isn't "is this rent good." It's what the farm actually needs: does the connection support what's being proposed, does the scale match the land and the operation, and what happens to this site in year 30 regardless of who owns the development by then. Rent is the number that gets discussed first because it's the easiest to compare. It's rarely the number that decides whether the deal was actually a good one.
What This Means for Businesses Like Mine
If you're a working farm being approached about a solar or battery lease, the practical takeaway is this: treat the technical assessment as part of the cost of getting this right, not as something to skip because the developer's proposal looks complete. A short, independent look at the site and the connection before you sign anything costs far less than discovering the gap after 40 years are already locked in.
Solar and battery diversification is increasingly part of how farms stay viable. With more than a quarter of farm businesses now generating solar energy, and that figure rising fast, the question isn't whether to consider it. It's whether the deal in front of you was checked by anyone who isn't trying to sell it to you.
I'd rather tell you this is the wrong scheme for your site than watch you sign a lease that locks in the wrong answer for 40 years. My auntie's farm isn't there in the same way any more, but the way she thought about land — slowly, carefully, on her own terms — is the way I still think every farmer deserves to be able to approach this.

Q: What are the biggest legal risks for farmers leasing land for solar? A: The most commonly cited risks are decommissioning costs at the end of the lease, tax exposure including capital gains and loss of agricultural reliefs, and restrictive easements created for access. Decommissioning work alone can cost tens of thousands of pounds if the lease doesn't include a proper bond or fund to cover it. Independent Solar Consultants recommends technical and commercial review happens before any of these terms are negotiated. FarmingUK
Q: Should I get a solicitor before signing a solar lease? A: Yes — rural legal specialists are clear that once heads of terms are signed, your room to negotiate is much more limited. But legal advice protects you from a bad contract; it doesn't tell you whether the underlying scheme — scale, grid connection, site suitability — is right for your farm. Both should be checked, ideally with technical review first. FarmingUK
Q: How much should I be paid to lease land for a solar farm? A: Reported rates vary widely, with guaranteed index-linked rents around £600 per acre being common, though many agreed solar rentals are closer to £950 per acre plus additional payment if battery storage is included. Independent benchmarking before negotiating is the only way to know if a specific offer is competitive for your land and connection. Strutt & Parker
Q: Can a solar developer add battery storage to my lease later? A: Often, yes. Developers frequently reserve the right to install battery systems at a future date, so it's important the original lease protects your interests if that happens, including additional payment terms. Strutt & Parker
Q: Is solar farming bad for food security? A: It's contested. Some MPs and farming bodies argue solar is disproportionately built on top-grade agricultural land and call for a ban on Best and Most Versatile land, while others, including farmers themselves, argue diversification income is now essential to keep mixed farms viable at all. Independent Solar Consultants assesses each site on its own technical and commercial merits rather than taking either position as a default. Farmers Weekly
