Solar Panels for Pubs and Gastropubs

The pub load profile, honestly assessed

Pubs are a more interesting solar case than they first appear. The headline trade is evening-led, which looks like a poor match for daytime generation — but the load underneath tells a different story. Cellar cooling runs 24 hours a day to keep beer at temperature, and it works hardest on hot afternoons when the array is at peak output. Bottle fridges, ice machines, and glasswashers cycle constantly. A gastropub kitchen starts prep mid-morning and runs through last food orders, pulling extraction, refrigeration, and cooking loads across the entire generation window. Add daytime trade — and most food-led pubs now take more at lunch and afternoon than a decade ago — and a typical pub self-consumes 55–75% of a sensibly sized array without storage.

Pubs also tend to have something town-centre restaurants lack: roof. Function rooms, kitchen extensions, skittle alleys, and outbuildings offer mounting space that a high-street unit cannot match, and car park or garden outbuildings sometimes suit ground-adjacent arrays. The constraint is rarely space; it is roof condition and orientation, which is why feasibility starts with photographs and a structural sense-check rather than a sales visit.

The numbers for a typical pub

A 15 kW system on a food-led pub costs roughly £18,000–£24,000 installed and generates around 13,000 kWh a year. At 2026 commercial rates and 65% self-consumption, that is worth £2,800–£3,800 a year in avoided purchases plus a modest Smart Export Guarantee top-up — a 5–7 year payback before tax relief. The Annual Investment Allowance deducts the full cost from taxable profits in year one, which for a profitable operator effectively knocks a quarter off the net price. Larger gastropubs at 25–30 kW scale see proportionally better cost per kW and similar paybacks on bigger absolute savings. Full worked examples are on the costs page, and the tax detail is in the VAT and capital allowances guide.

Ownership structures: who says yes

Pub tenure shapes the project more than any technical factor. Freeholders simply proceed. Free-of-tie leaseholders need landlord consent — usually granted as a licence for alterations, and increasingly welcomed because of the EPC uplift. Tied tenants need pubco consent, and the smart approach is to frame the proposal around the pubco's own estate interests: better EPC, lower tenant operating costs, more resilient tenancy. Several major pub companies now run their own rooftop programmes, so the concept needs no introduction. Where the tenancy has under five years to run, we say so plainly: the payback maths needs either a longer lease or a landlord contribution.

Heritage buildings, handled properly

A meaningful share of the UK's pub stock is listed or sits in a conservation area, and this is where pub solar most often goes wrong in inexperienced hands. The rules are workable: Listed Building Consent for listed properties, with arrays placed on rear slopes, flat roofs behind parapets, or outbuildings; conservation area policies that restrict street-visible panels but rarely prohibit concealed ones. What kills projects is discovering these constraints after design. Our feasibility checks the heritage position first, and where consent is unlikely we suggest the alternatives — outbuilding arrays, or simply saying no honestly.

Trading through the install

Pub installations take three to eight days on the roof for typical system sizes, with scaffolding placed to keep the front door, garden, and delivery access open. The only power-down is the final connection — two to four hours, booked for a closed morning. Cellar cooling tolerates that window comfortably with doors kept shut; we plan it with your cellar services schedule, not against it.
