Solar farm land leases: how much are landowners actually being paid in 2026?

If you farm or own land in the UK, you may already have a letter from a solar developer. If not, one may be on its way. The pitch usually leads with a number — “we can offer you £X per acre.” Developers frame this as guaranteed, inflation-proofed income for little more than signing an option agreement.

Some of these numbers are genuinely in line with the market. Others are opening bids designed to look generous against a rent you’ve never had reason to benchmark. This piece sets out what independent rural surveyors say landowners actually earn in 2026. It also covers what moves that figure, and the tax dimension that rarely makes it into the developer’s letter.

What the market actually pays

Two of the UK’s established rural advisory practices publish figures worth anchoring to. Use these instead of relying on whatever a single developer’s letter claims:

Source	Reported rate	Basis
Savills Research	£2,500 per hectare/year (£1,010 per acre)	Industry-quoted return for large-scale solar PV leases
Strutt & Parker	In excess of £1,000 per acre/year	Recommended minimum for a 25-year lease with no extension or renewal rights
Typical Farm Business Tenancy (FBT)	£150–£200 per acre/year	For comparison — ordinary arable or grazing rent

Both figures land in the same broad range. Both also sit five to seven times above ordinary rent. That’s what the same land would earn under a normal Farm Business Tenancy. That gap is the whole commercial logic of a solar lease.

A developer can afford to pay well above agricultural rent. That’s because the land, once connected and consented, generates revenue at a scale farming could never match.

Treat these figures as a starting point for negotiation, though, not a fixed market price. The rent a specific site actually commands can move a long way from that midpoint in either direction. A competent adviser earns their fee in that negotiation, not by accepting the first offer.

What actually moves the number

The headline “£1,000-plus an acre” hides real variation. In practice, the rent a developer will pay depends on:

• Grid proximity and headroom. A site close to a substation with spare capacity saves the developer a six- or seven-figure reinforcement bill. As a result, they’ll pay more to secure it. A site further out, or in a constrained part of the network, starts from a weaker negotiating position.
• Site size and shape. Larger, regularly shaped, unshaded parcels cost less per megawatt to build and cable. Developers reflect that saving in the rent they’re prepared to offer.
• Agricultural Land Classification (ALC). National planning guidance treats land graded 1, 2 or 3a as “best and most versatile” (BMV). It steers large ground-mount schemes away from that land. A Grade 3b or lower site is a stronger, faster-consenting planning proposition. That can mean a better rent, not a worse one. It removes planning risk from the developer’s side of the deal.
• Lease term and structure. Most solar leases run 25 to 40 years. They’re index-linked, so the rent doesn’t erode against inflation over that span. That said, the indexation mechanism itself is worth scrutinising. A fixed-percentage annual uplift and a full RPI or CPI link can diverge meaningfully over three decades.
• Whether there’s real competitive tension. A single developer with no rival bidder has little reason to move off their opening number. A developer who knows you’re comparing offers, or that you’ve taken independent advice, has much more reason to negotiate.

Grid connection is the constraint behind the price

Every one of those factors ultimately traces back to the same bottleneck: headroom on the local electricity network. Ground-mounted schemes of any scale fall under Engineering Recommendation G99. That’s the framework governing how generation connects to a DNO’s network.

That process starts with an initial enquiry and a formal application. For larger arrays, it also requires a full technical assessment before the DNO issues a connection offer.

In rural areas, spare grid capacity is often scarcer than the land itself. A site with a strong connection nearby can command meaningfully more rent. However, a field two or three miles from the nearest substation earns less.

Reinforcement costs, or a place in a connection queue, eat into what the developer can afford to pay you. “We have a connection offer” is a claim worth verifying before signing anything exclusive. It’s not a detail to take on trust.

The inheritance-tax catch the rent figure doesn’t show

Here’s the part almost no offer letter volunteers. Land farmed in-hand, or let on a Farm Business Tenancy, has generally qualified for Agricultural Property Relief (APR). This APR shelters it from inheritance tax.

But once someone leases that land for solar, it’s no longer in agricultural use. As a result, the land generally loses APR eligibility. That’s a point Savills’ own research on renting land for renewables makes plainly.

That matters more than it used to. From 6 April 2026, reforms to APR and Business Property Relief take effect.

Under these reforms, each estate gets a combined allowance for qualifying agricultural and business assets. The first £2.5 million of that combined total stays free of inheritance tax. That threshold is up from an originally proposed £1 million cap.

The government revised it after representations from the farming sector, and confirmed the change on 23 December 2025. Above that £2.5 million allowance, relief drops to 50%. That gives an effective 20% inheritance-tax rate on the excess, rather than the standard 40%.

Spouses and civil partners can also transfer the allowance between each other. As a result, a couple can shelter up to £5 million between them (GOV.UK — inheritance tax reliefs threshold to rise to £2.5m).

Here’s the practical effect for a landowner weighing a solar lease. Take land that would sit inside your £2.5 million agricultural-relief allowance while farmed. Once you let it for solar, though, that same land can fall outside any relief at all.

That’s because it’s no longer agricultural property for APR purposes. As a result, that value falls into the taxable part of your estate. That’s true no matter how generous the new threshold is. That doesn’t make leasing the wrong decision, though.

It makes leasing something to model against your own estate and succession position before you sign. Weigh it alongside the rent itself, not after.

Agrivoltaics — the one option that can protect both

Where grazing continues beneath or between the panels — agrivoltaics — the land can, in principle, remain in genuine agricultural use. This is worth raising directly with the developer at heads-of-terms stage, rather than waiting for them to offer it. It also tends to strengthen the planning case on better-quality land. That’s because a scheme that keeps grazing viable is easier to defend against BMV land policy.

Whether it changes the APR position for your specific arrangement is a question for your own tax adviser. There’s no general rule here. But it’s the strongest card available if keeping some agricultural status matters to you.

Weighing the offer properly

A land-lease offer and an on-site self-supply system solve different problems. The right answer for your holding depends on your appetite for capital risk and your succession plans. It also depends on what you actually need the land to keep doing. We set out this comparison in full in our land lease vs on-site solar guide.

Suppose a lease looks like the right route for your site. Our energy and ROI modelling service compares the rent on offer, the lease structure, and the tax position. It weighs all three against the alternative. That way, you can test the number in the letter properly before you sign anything.
