Solar farm rents in the UK are typically around £1,000 to £1,200 per acre a year, linked to inflation, on leases of 30 to 40 years or more. Sites with a strong grid connection can earn more. Here’s how it works, in plain English.
The headline figure
- Around £1,000 per acre a year is the figure most often quoted. Land agents have reported recent offers of up to £1,200 per acre, index-linked.
- Some deals add a turnover top-up: a share of the solar farm’s income on top of the base rent.
- The rent is usually linked to inflation (RPI or CPI), so it rises over time.
What affects your rent
- The grid connection. This matters most. Land close to a substation with spare capacity is worth far more to a developer.
- Sunshine. More sun means more power. The South West does well here.
- Size and shape. Larger, simpler fields are cheaper to build on.
- Constraints. Flood zones, protected landscapes and listed buildings nearby make planning harder.
How the deal is structured
- Option period. First, the developer takes an option on your land, often for one to five years, while they secure planning and a grid connection. Whether you are paid during the option depends on the deal.
- Lease. Once the project goes ahead, the lease starts. Full rent usually begins when construction starts.
- Length. Leases used to run for 25 years. Most new leases now run for 40 years or more.
- Decommissioning. At the end, the panels are removed and the land is restored. Good leases require money to be set aside for this, usually built up from around year 10 to 15.
- Legal fees. It is normal for the developer to pay your reasonable legal fees. We do.
Tax: check before you sign
- From 6 April 2026, full inheritance tax relief on agricultural and business property applies to the first £2.5 million per person. Couples can pass on up to £5 million. Above that, relief is 50%.
- Land let for solar may lose agricultural property relief, because it is no longer farmed in the usual way. Grazing sheep under the panels and careful planning may help.
- Solar can also raise the value of your land, which can affect your tax bill.
- Speak to your accountant or land agent early. We are happy to work with them.
Can I still farm the land?
Often, yes. The panels and kit disturb less than 2% of the ground, and sheep commonly graze between the rows. Since February 2024, new solar farms must also deliver a 10% gain in biodiversity, so part of the site is often managed for wildlife.
