Tenant farmer solar: how to get landlord consent in 2026

Roughly 30% of England’s agricultural land is farmed under tenancy — and the proportion is higher for the largest holdings. For tenant farmers, the solar PV opportunity is real but adds one layer of complexity: any structural alteration to a building, including rooftop PV, requires the landlord’s consent. The good news: institutional rural landlords have moved a long way in the last decade, and the standardised tenant-PV lease addendum is now the norm rather than the exception.

Who the major institutional landlords are

The big institutional landlords across England’s tenanted farmland include the Crown Estate, Church Commissioners (the Church of England’s investment arm — substantial rural portfolio), Wellcome Trust (significant Lincolnshire and East Anglia holdings), Duchy of Cornwall (south west of England), NFU Mutual Estates, the National Trust (where farms are let alongside heritage estate management), and major county council farm estates (Norfolk, Cambridgeshire, Lincolnshire, Wiltshire and several others run county farms specifically as agricultural ladder programmes).

The other large category is family estates — Buccleuch (largest private landowner in the UK), Cadogan, Grosvenor, Bedford (Woburn), Devonshire (Chatsworth, Bolton Abbey), Northumberland Estates, Cornwall Estate (Boconnoc, others), and a long tail of regional estates each managing thousands to tens of thousands of acres of let farmland.

Most of these landlords now have a standardised tenant-PV lease addendum. Ask your land agent for the current version.

What the addendum typically covers

A standard tenant-PV addendum covers: (1) tenant right to install rooftop PV at tenant’s cost, on named buildings, subject to landlord approval of design; (2) ownership of the PV system during the lease — typically tenant-owned with reversion to landlord at lease end, or tenant-owned with a buyout option at end of term; (3) responsibility for compliance — planning, electrical, insurance, decommissioning; (4) treatment of generated electricity — typically tenant takes all benefit; (5) treatment of SEG export income — tenant takes; (6) reversion arrangements at lease end — usually the system passes to the landlord or to an incoming tenant, with potential compensation under the existing tenancy framework.

The TRIG (Tenancy Reform Industry Group) guidance covers the regulatory framework. Most institutional landlords have aligned their addenda with TRIG and AHDB tenant-PV guidance.

Private landlords — different conversation

Private landlords vary enormously. Some are sophisticated and enthusiastic — particularly landowning farming families who manage their own tenanted portfolio. Others are inexperienced or risk-averse and need careful walking through the conversation. Common private-landlord objections: (1) “It will damage the roof” — addressed with structural survey and roof-warranty terms; (2) “What happens when you leave the tenancy” — addressed in the addendum; (3) “We might develop the building for other uses” — addressed with break clauses; (4) “We want the income from the install” — addressed by exploring landlord-funded models with service-charge recovery from the tenant.

Some private landlords prefer to fund the install directly and recover via service charge — useful for landlords with capital and tenants without, but typically less economic for the tenant over the medium term.

Step-by-step process

The standard sequence for a tenanted-farm PV project: (1) Tenant engages with our team and we run desk feasibility from meter data and roof drawings; (2) We draft the proposal in a format that names the buildings, the system specification, and the timeline; (3) Tenant forwards to their land agent or directly to landlord; (4) Landlord (or agent) responds — typically requesting the lease addendum or proposing terms; (5) Negotiation completes the addendum, typically 4–8 weeks for institutional landlords, 6–12 weeks for private; (6) Survey and detailed design follow; (7) Install proceeds.

For institutional landlords with a standard addendum already in place, the consent stage can be as fast as 2 weeks if there are no design concerns. For private landlords without a prior addendum, expect 8–12 weeks for the conversation to complete.

Financing options for tenants

Tenants can fund solar PV through: (1) Capital — pay upfront, claim AIA; (2) Asset finance — bank or specialist lender, typically 5–10 year terms, EBITDA-positive from month one for most farms; (3) PPA — third-party developer owns the system and tenant buys the electricity at a discounted rate; (4) Landlord-funded with service charge recovery — landlord pays capex, tenant pays a monthly service charge that covers the landlord’s return. For most tenants the right answer is asset finance for capital-light cash flow, but the right comparison depends on the lease term remaining, the farm’s tax position, and the tenant’s capital priorities.

Common pitfalls

Things we see go wrong on tenanted-farm PV projects: (1) Tenant proceeds without the addendum and the landlord later challenges — always get the addendum signed first; (2) Lease has insufficient remaining term to justify the payback — typically need 10+ years remaining for capital-purchase economics; (3) Landlord requires removal at end of lease without compensation — addendum should address reversion; (4) Tenant unclear on insurance allocation between landlord buildings cover and tenant PV cover — address upfront with both insurers’ approval; (5) Landlord and tenant both want SEG export income — sort it in the addendum.

We’ve delivered dozens of tenanted-farm PV projects across the UK since 2018 and the landlord engagement workstream is now a standard part of our scope. If you’re a tenant considering solar, the worst thing to do is delay the landlord conversation — start it early, share our proposal format, and the addendum process moves much faster than people expect.
