Pubs, Restaurants & Hospitality Venues: Solar panels for pubs

Why a pub is one of the most natural homes for commercial solar

A working pub draws power right through the trading day, and that is exactly what makes solar panels for pubs such a sensible investment rather than a gesture. Cellar cooling runs constantly to keep beer and cask in condition, kitchen extraction and refrigeration build through every service, glass washers and coffee machines cycle all afternoon, and lighting carries the room from lunch into the late evening. Because all of that demand lands squarely in daylight and early-evening hours, the electricity your panels generate is used on the premises rather than sold back to the grid at a lower rate. Self-consumption is the single biggest driver of solar payback, and a busy pub or restaurant typically uses a high share of what it produces, which is why a typical install pays back in around six and a half years and then runs, largely cost-free, for the decades that follow.

Energy has become one of the largest controllable costs a licensee carries, sitting alongside wages and stock, and unlike those it is a cost you can largely fix for twenty years with a single decision. A predictable electricity bill is a rare lever in a trade where margins are tight and input prices are set elsewhere, and a system that owns a slice of your supply for two decades insulates you from the next round of tariff shocks. On top of the saving, a visible rooftop array gives an independent free house or a managed estate a credible, auditable sustainability story for customers, brewers and investors, and it nudges leased premises towards the EPC B Minimum Energy Efficiency Standard expected for commercial property by 2030, which matters increasingly to landlords deciding whether to renew or invest in a site. With the 100% Annual Investment Allowance, the Smart Export Guarantee and the Workplace Charging Scheme all available in 2026, the commercial case for putting solar on a pub is as strong as it has been in a decade, and the surfaces most pubs already own (kitchen extensions, function wings, car parks and beer gardens) give more room to work with than operators expect.

What a typical pub install looks like and how we size it

For a pub or restaurant we usually design a system in the 10 to 100 kW range, which is roughly 18 to 185 panels across about 60 to 600 square metres of roof. In practice that is rarely the original public frontage. We favour the flat-roofed kitchen extension, the function-room wing, the trade outbuildings and the lean-to plant rooms, which keep the array off the elevations that matter for heritage and kerb appeal. A system of that size generates in the region of 9,000 to 92,000 kWh a year and saves somewhere between 2 and 21 tonnes of CO2 annually, a figure your group can put straight into its sustainability reporting.

We never simply fill the roof, because a pub is not a constant-load building. Demand peaks around lunch and evening service and dips in the quiet midmorning and mid-afternoon, so over-sizing wastes money on power you would only ever export at a low rate. Instead we size a modest array to the genuine daytime cellar, kitchen and lighting baseload, then layer in EV charging to soak up the midday generation that would otherwise be exported. Where roof space is tight, which it often is on a historic site, a beer-garden canopy or a car-park solar carport adds meaningful capacity without touching the listed elevations, and gives drinkers shade and customers an EV-ready bay into the bargain. Throughout, we pull at least twelve months of half-hourly meter data and model EV-charging growth into the load before we settle the final size, so the system matches how your pub actually trades across the week and the seasons rather than an optimistic snapshot.

Costs, payback and tax relief

A pub project typically lands between £10,000 and £90,000 depending on the size of the site and the roof available, with a simple payback near 6.5 years and the electricity effectively free for the fifteen to twenty plus years that follow commissioning. A small wet-led local at the lower end of that range is a very different proposition to a large roadside dining pub with a sprawling kitchen, and we cost each on its own load and roof rather than a rule of thumb.

The biggest financial lever is tax. Solar PV qualifies as special-rate plant and machinery, so the 100% Annual Investment Allowance lets most pub businesses write off the full cost against profit in year one, worth up to a quarter of the project value back as tax saved for a limited company that pays corporation tax. It is worth being precise here: solar is a special-rate asset and does not qualify for full expensing or the old super-deduction, so we claim through the AIA, or the 50% First-Year Allowance where a managed estate rollout pushes total spend above the £1m AIA cap. Any surplus you do export is paid for under the Smart Export Guarantee, which matters most for pubs that are quieter midweek or out of season, when generation can outrun the cellar and kitchen load. Our cost guide sets out worked numbers for different sizes of pub, from a single free house to a multi-site estate, so you can see where your site is likely to land before you commit to a survey.

Funding routes in detail

Most single-site pubs fall well within the £1m AIA cap and are fully expensed in year one under Plant and Machinery Capital Allowances, with the 50% First-Year Allowance available where a managed estate rollout takes spend above the cap and the relief has to be split. The Smart Export Guarantee pays a supplier-set rate, typically four to fifteen pence per kWh in 2026 with some smart and time-of-use tariffs higher, for power you send back to the grid, and because those rates are not capped or regulated we shop around on your behalf rather than accepting whatever your incumbent supplier offers.

If you are adding chargepoints for staff or customers, and many roadside and destination pubs now are, the Workplace Charging Scheme covers up to 75% of purchase and installation cost, five hundred pounds per socket and up to twenty thousand pounds per applicant from April 2026, capped at forty sockets. It pairs naturally with solar because daytime charging self-consumes generation at full value, turning the most valuable kWh on the system into a customer-facing amenity. The scheme has been extended for a final year and closes permanently on 31 March 2027, so applications should be made well ahead of then. For most pubs the funding picture is AIA plus the Smart Export Guarantee, plus the Workplace Charging Scheme where EV charging is in scope, and we map the combination that fits your business and handle the paperwork so you are not chasing it yourself.

Compliance and sector considerations

Many pubs are listed or sit in conservation areas, so Listed Building Consent and early engagement with the conservation officer are often required, and we design around that rather than treating it as a blocker. The usual answer is roof slopes hidden from public view, low-profile all-black panels, or carports and outbuildings that leave the protected frontage untouched, an approach plenty of heritage pubs now run successfully. Tied and leased houses within a pubco or brewery estate need landlord consent and usually a wayleave or licence to alter, which we provide as a template and run on your behalf, and we model both tenant-funded and landlord-funded routes so everyone can see who pays and who benefits.

On the technical side, older premises frequently have a constrained single-phase supply that can cap system size without a DNO upgrade, and a G99 application is required for connections above 17 kW per phase. The roof itself can be the catch: pre-2000 trade outbuildings often have asbestos cement sheeting that cannot take panels and needs replacing first. Across all of this the usual standards apply: MCS commercial certification for SEG eligibility, NICEIC or NAPIT electrical work, RECC and TrustMark, the SPF1981 rooftop fire-safety standard that insurers increasingly expect, and CDM 2015 on larger installs. Where your group is a large undertaking, on-site solar is also one of the most credible recommendations an ESOS energy audit can carry, and it reduces metered grid consumption directly.

How we approach this kind of project

We start with at least twelve months of your half-hourly meter data so the system is sized to the load your pub genuinely draws across the trading week, not to an optimistic roof-fill figure that looks good on paper and underperforms in practice. We check the roof build-up and survey for asbestos cement sheeting before we quote, never on the day of the install, so the fixed price we give you holds without nasty surprises mid-project. Where the supply or export capacity is the constraint, we submit the G99 grid application early, alongside the structural survey, to start the clock on what is usually the longest single item in the programme.

You receive one clear fixed-price proposal that models self-consumption against export, covers any landlord or brewery consent, and sets out the funding routes side by side. The workmanship is backed by an insurance-backed warranty, and you get 24/7 remote monitoring with automated underperformance alerts so a fault is flagged rather than quietly costing you generation. We work around your trading pattern in zones so the doors stay open, and the only outage needed is the final grid connection, typically a few hours that we book for a quiet period or a planned shutdown. For groups, we design one repeatable template (rooftop, optional canopy, EV charging and a single dashboard) that rolls across the estate with standard surveys and standard hardware, so you are not re-engineering every site from scratch.

An illustrative example

As an illustrative composite based on typical UK projects, and not a real named client: a managed pub-and-restaurant group piloted solar on a flagship roadside dining pub with a large flat-roofed kitchen extension and a sixty-space car park. The site ran heavy kitchen extraction, cellar cooling and lighting, and the group wanted a repeatable template before committing the wider estate. The pilot put around 92 kW on the rooftop with a design option for a 40 kW beer-garden canopy, generating in the region of 85,000 kWh a year for an annual saving near £21,000 and a payback close to 6 years. A single standardised design (rooftop, optional canopy, EV charging and one monitoring dashboard) was signed off for rollout across forty estate sites, the brewery wayleave template was agreed once and reused, and portfolio pricing with a phased three-year capital plan was put in place. The figures are illustrative and depend on your site, tariff and roof, but they show how a single well-designed pilot can de-risk a whole estate decision.
