If a developer has approached you about leasing your land for a wind turbine, solar array or biomass facility, the paperwork in front of you will shape what happens on that land for the next quarter of a century or longer. A land lease for a renewable energy project is not a standard agricultural tenancy or commercial lease. It carries its own commercial logic, its own risks around access and restoration, and its own knock-on effects for farming operations, mortgages and inheritance planning. This guide walks through the main commercial and legal points a UK landowner should weigh up before committing. It covers option agreements, rent structures, grid connection, decommissioning, and the practical questions that tend to catch landowners out further down the line.

What this document is

A land lease agreement for a renewable energy project is a contract between a landowner and an energy developer that grants the developer the right to install and run generating equipment on part or all of an estate. In England and Wales these are typically structured as long leases, often 25 to 40 years, sometimes with extension options.

The developer pays the landowner either a fixed rent per acre, a percentage of gross revenue from electricity sales, or a blended arrangement combining a base rent with a turnover top-up. Before the lease itself, most deals begin with an option agreement or exclusivity agreement.

This gives the developer time, usually two to five years, to secure planning permission, a grid connection offer and project financing. Only if those come together does the lease actually start. The landowner agrees not to negotiate with rival developers during that window and usually receives a modest option fee in return.

How to use this document

  1. Review the option agreement carefully. Before any lease takes effect, you will usually sign an option or exclusivity agreement. Check how long the developer has to trigger the lease, what milestones they must hit, and whether the option fee compensates you fairly for locking your land away from other opportunities during that period.
  2. Negotiate the rent structure and review mechanism. Rent can be a flat payment, a percentage of revenue, or both. Turnover rents expose you to electricity price movements while fixed rents do not. Make sure there is a clear index-linked review clause, typically tied to CPI or RPI, and understand how rent is calculated during commissioning versus full operation.
  3. Define the lease area and access rights precisely. The agreement should specify exactly which parts of your land are leased, which are subject to easements for cables and access tracks, and which remain fully under your control. Vague definitions cause expensive arguments later, especially where cable routes cross fields you want to keep farming.
  4. Pin down decommissioning and reinstatement obligations. The developer should be contractually required to remove turbines, panels, inverters, foundations and cabling at the end of the term, and to restore the land to a defined standard. Ask about a decommissioning bond or parent company guarantee so you are not left with the bill if the operator becomes insolvent.
  5. Check the impact on your wider estate. A lease of this length affects mortgages, agricultural property relief for inheritance tax, single farm payment entitlements, and any existing tenancies. Speak to your lender, your accountant and an agricultural specialist before signing, because fixing problems after completion is far harder than negotiating them in.

Common questions

Q How long do renewable energy land leases typically last?
Most leases for wind and solar projects in the UK run for 25 to 40 years from the start of commercial operation, with some developers seeking extension options on top. Battery storage leases tend to be shorter, often 20 to 25 years. The length usually reflects the expected operational life of the equipment and the period needed for the developer to recoup investment and return a profit to financiers.
Q What rent can I expect for leasing land to a solar or wind developer?
Rent varies widely depending on location, grid proximity, project size and current electricity prices. Arrangements can be a fixed rent per acre, a percentage of revenue, or a hybrid. Market rates change frequently, so benchmark offers with a rural surveyor or land agent who handles renewables regularly rather than relying on figures quoted by the developer alone.
Q Do I need planning permission, or does the developer handle it?
The developer usually leads the planning application at their own cost, but the application is made against your land and may require your cooperation as landowner. Most option agreements include a clause allowing the developer to withdraw if planning is refused. You should make sure you are not left tied into a lease if the project cannot actually be built.
Q What happens if the developer sells the project or goes bust?
Leases are usually assignable, meaning the developer can sell the project to another operator, often a pension fund or infrastructure investor, without needing your consent. If the operator becomes insolvent, your protection comes from the decommissioning security, any parent company guarantee, and step-in rights for funders. These clauses deserve close attention during negotiation.
Q Will a renewable energy lease affect my inheritance tax position?
Potentially yes. Land under a long commercial lease to a developer may no longer qualify for agricultural property relief in the same way as actively farmed land, and business property relief treatment depends on the structure. The tax position is fact-specific and has been subject to recent policy changes, so take specialist tax advice before signing anything long term.
Q Can I still farm or graze the land once it is leased?
For solar sites, sheep grazing between and under panels is common and often written into the lease. For wind farms, the turbine bases and access tracks take up a small footprint and the rest of the field can usually remain in agricultural use. The specific rights need to be set out clearly in the lease rather than left to assumption.
Q What is a decommissioning bond and do I need one?
A decommissioning bond is a ring-fenced sum, or a bank guarantee, held to cover the cost of removing equipment and restoring the land at the end of the lease. Without one, you risk inheriting the clean-up bill if the operator has no money left by year 30. Most experienced landowners insist on some form of security before signing.
