Landowner Energy Investments UK: Legal Guide 2025
We're not a law firm — we help you find the right legal support. For advice on your situation, speak to a legal adviser or find a solicitor.
The shift towards cleaner energy in the UK has opened up genuine commercial opportunities for landowners. Whether it's a solar array on underused pasture, a wind turbine on an exposed hillside, or a battery storage site near a grid connection, developers are actively looking for suitable land.
For the landowner, this can mean a steady income stream that runs alongside farming or other activities, and a useful hedge against changes to agricultural support payments. That said, the decisions you make at the start of a project tend to bind your land for decades.
I've written this guide to walk through the legal questions worth thinking about early, from choosing a developer to reading the small print of option agreements and leases. It's aimed at owners weighing up their first approach, not seasoned energy investors.
Overview
When we talk about a landowner 'investing' in a renewable energy project, it usually doesn't mean putting money in. More commonly, the landowner contributes the land itself, typically under a long lease or an option-then-lease arrangement, and the developer builds, funds and operates the scheme.
The landowner receives rent, and sometimes a share of generation revenue or community benefit contributions. The main technologies you'll see in the UK are ground-mounted solar PV, onshore wind, battery energy storage systems (BESS), anaerobic digestion, and occasionally hydro on suitable watercourses.
Each has different land requirements, grid connection issues, and planning considerations. Arrangements can run for 25 to 40 years or more, which is why getting the legal structure right matters so much. A badly drafted agreement can restrict how you use neighbouring land, complicate future sales, create tax headaches, and, if the project fails, leave you with infrastructure you didn't ask for. This guide focuses on the legal and commercial groundwork rather than the engineering side.
Key steps
- Do your homework on the developer. Before signing anything, look into the company approaching you. How many projects have they taken from planning through to operation? Are their accounts healthy? Who actually funds and builds their sites, and who will own the asset long term? Speaking to other landowners who've worked with them is often the most revealing step of all.
- Understand the option agreement stage. Most deals start with an option or exclusivity agreement rather than a lease. This gives the developer time, often two to five years, to secure planning permission and a grid connection. Check the option fee, the exclusivity period, any extension rights, and what happens to your land use during this time. Your ability to sell or use the land may be restricted.
- Scrutinise the lease terms carefully. When the option is exercised, a long lease kicks in. Focus on the term length, rent review mechanism, indexation (often RPI or CPI), any revenue share, break clauses, and assignment rights. Pay particular attention to what the developer can do on the land, access rights, cable routes, and restrictions placed on the rest of your holding.
- Plan for decommissioning from day one. At the end of the project, who removes the panels, turbines, foundations and cabling? A well drafted lease will include a decommissioning obligation backed by a bond, parent company guarantee, or escrow arrangement. Without this, you could inherit a site full of redundant kit and a significant restoration bill decades from now.
- Think about tax, succession and lender consent. A long energy lease can affect inheritance tax reliefs like Agricultural Property Relief, trigger business rates, and change your VAT position. If the land is mortgaged, your lender will almost certainly need to consent. Speak to your accountant and mortgage provider early, not after you've signed heads of terms.

Common questions
Q How much rent can a landowner expect from a renewable energy project?
Rent varies widely depending on technology, location, grid capacity, and project scale. Solar and battery storage tend to pay per acre or per megawatt, while wind schemes often include a revenue share linked to generation. Figures shift with the market, so it's worth getting independent valuation advice rather than relying on the developer's offer. A specialist agricultural or energy surveyor can benchmark what's reasonable for your site.
Q Do I need planning permission, or is that the developer's job?
The developer handles the planning application and carries the cost and risk of securing permission. Your role is usually to cooperate, for instance by signing consent forms as landowner. However, you should understand what's being proposed because planning conditions can affect access, screening, noise and hours of operation on your wider holding. Read the application before it's submitted.
Q What happens if the energy company goes bust during the lease?
This is one of the most important risks to cover in the lease. Projects are often held in special purpose vehicles with limited assets, so you want protections such as parent company guarantees, step-in rights for funders, and a decommissioning bond held separately. Without these, an insolvency could leave infrastructure on your land with no one obliged or able to remove it.
Q Will a long energy lease affect my ability to sell the farm?
You can still sell land that's subject to an energy lease, but the buyer pool may narrow and the price impact varies. Some buyers value the income stream; others see it as a restriction. Mortgage lenders will view the land differently too. Option agreements in particular can make a sale difficult during the exclusivity period, so factor this into your timing.
Q Can renewable energy income affect Agricultural Property Relief?
It can. Land used for commercial energy generation is generally not treated as agricultural for inheritance tax purposes, which may reduce or remove APR on the leased area. Business Property Relief may or may not apply depending on how the arrangement is structured. This is a specialist tax area, and the rules do change, so take professional tax advice before committing.
Q Should I use my own solicitor or the one the developer suggests?
Always instruct your own solicitor, ideally one with genuine experience in energy leases and rural property. Developers often offer to contribute to your legal costs, which is helpful, but the solicitor must act for you and only you. These agreements typically run for decades, and a generic conveyancing approach won't pick up the commercial detail that matters.
Q What's the difference between an option agreement and a lease?
An option gives the developer the right, but not the obligation, to take a lease later, usually once planning and grid are secured. During the option period your land is tied up but no long term lease is in place. If the option is exercised, the pre-agreed lease is granted. If it isn't, you keep the option fee and your land is released. Both documents need careful review.
