Getting Landlord Consent for Solar on a Leased Restaurant

The single most common reason a viable restaurant solar project stalls is not money, engineering, or planning — it is the lease. Most hospitality operators are tenants, the roof belongs to someone else, and the project dies in an unanswered email to a managing agent. It does not have to. Landlord consent for commercial solar is being granted more readily every year, because the regulatory pressure on landlords has quietly flipped the incentive. Here is how to run the conversation properly.

Why landlords are saying yes more often

The lever is the Energy Performance Certificate. Minimum Energy Efficiency Standards already prohibit letting commercial property rated F or G, and government proposals point toward requiring EPC C by 2027 and B by 2030 for commercial lettings. Whatever the final dates land as, the direction is fixed: landlords across the UK hold buildings whose lettable status depends on improving their energy performance, and rooftop solar is one of the cleanest EPC improvements available — no disruption to the interior, no change of use, and in the standard tenant-funded structure, no landlord capital at all.

Put bluntly: a tenant offering to improve the landlord’s compliance position at the tenant’s expense is making the easiest ask in commercial property. The proposal just has to be framed that way.

Check your lease before you ask

Three clauses determine the shape of the request. The alterations clause governs whether roof works need consent and in what form — most leases require landlord consent for structural or external alterations, usually “not to be unreasonably withheld.” The demise defines what you actually rent: some leases include the roof within the demised premises, many stop at the ceiling. If the roof is outside your demise, you need a licence to access and use it, not just consent to alter. And the yield-up/reinstatement clause decides what happens at lease end — whether the system must be removed, or can transfer to the landlord (often the cleanest answer, and a negotiating chip: the landlord keeps a revenue-relevant asset at no cost).

Lease length is the other gating fact. A solar payback of four to seven years wants at least that much term remaining, or a break-clause-aware structure. Approaching a renewal? That is the single best moment to negotiate solar into the deal.

The structures that work

Tenant-funded with licence for alterations is the standard route: you fund and own the system, claim the Annual Investment Allowance, keep the savings, and agree reinstatement or transfer terms at yield-up. Landlord-funded with a green lease provision flips it: the landlord invests (they may have their own capital allowance and EPC motivations), and recovers through a modest rent adjustment or service charge — attractive where your lease is short or your capital is committed to the kitchen. Shared structures split the cost and the benefit, common in hotel and multi-let buildings. We produce the technical pack — system design, structural note, EPC impact statement, insurance confirmation — that supports whichever conversation you are having; landlords and their agents respond far better to a documented proposal than to a concept.

The conversation itself

Lead with their interests, not yours: EPC uplift toward the 2027/2030 thresholds, an improved asset at no cost, a tenant investing in the premises (which is, to any landlord, a tenant intending to stay and pay rent). Anticipate the standard concerns — roof warranty (we work with the roofing warranty holder and document it), structural loading (chartered engineer’s verification included), and what-if-you-leave (answered by the reinstatement terms). In our experience the median outcome of a properly documented request to a commercial landlord is consent within one to two months, with the genuinely contested cases concentrated in short leases and buildings already scheduled for redevelopment.

Tenancy questions are part of every feasibility we run — flag your lease position on the quote form and the proposal will address it directly. The numbers the landlord conversation rests on live on the costs page, and the tax position — including who claims what under which structure — is covered in the VAT and capital allowances guide.
