Brewpubs & Taprooms: Solar panels for breweries

Brewpubs and taprooms: two businesses under one roof

A brewpub or taproom carries a load profile that a standalone production brewery does not: you are running a brewhouse and a hospitality venue at the same address. That combination shifts the solar maths in your favour, and it is worth understanding why before you spend a penny.

Be clear-eyed first. Around 70% of the energy a brewery consumes is thermal, the wort boil, the hot liquor tank, steam and CIP, and solar PV cannot offset heat directly. That honesty matters. But a brewpub's electrical share is proportionally larger than a pure production site's, because the pub side is almost entirely electrical: cellar and glycol cooling, the kitchen, refrigeration, lighting, tills, card terminals and pumps, running from mid-morning prep through to a late evening close. Solar attacks that electrical load, and on a brewpub there is simply more of it relative to the brew kit.

The load profile: production by day, trade by night

Fermentation refrigeration is the single biggest electrical draw in any brewery, roughly 35% of electricity use, and it runs 24/7 while your fermentation vessels are working. Layer the hospitality demand on top: cellar cooling holding cask and keg at temperature, kitchen extraction and cooking, and a long trading day that stretches well past sunset. Daytime generation covers the brewing and the prep directly; the evening trade is where a battery earns its keep.

Because your consumption runs on into the dark, a modest battery (typically 10–30 kWh on a site this size) lets you store cheap midday solar and spend it across the evening service rather than importing at around 25p per kWh. Self-consumption on brewpubs is high, often 80–90%, precisely because something is always drawing power. That figure, not the export rate, is what drives your payback.

Sizing, cost and payback

Most brewpubs and taprooms land in a 15–60 kW system, costing roughly £13,000–£54,000 installed depending on roof, access and whether you add storage. At UK yields (around 850 kWh per kWp per year) and with self-consumption that high, payback typically falls near five years, on panels warrantied to keep producing for 25 years or more. Our cost breakdown shows how roof size, three-phase supply and battery choice move that number.

The "solar-powered pint", a marketing asset, not just a meter

A brewpub has something a warehouse-roof array never will: customers standing underneath it. Drinkers on the premises can be told, credibly, that the beer in their glass was brewed and poured on sunshine. That is a genuine, provable provenance story for your taproom boards, your SIBA credentials and your social channels, the kind of story a growing share of drinkers actively choose. It is a survival-margin decision first, but the front-of-house angle is a real bonus a production-only brewer cannot use.

The catch: older, listed, town-centre buildings

Many brewpubs occupy exactly the kind of historic town-centre property that complicates a rooftop install. Two issues recur:

• Listed status. If your building is listed, and a surprising number of Victorian pubs, tower breweries and converted maltings are, permitted development does not apply, and you will need Listed Building Consent before installing. Check whether your premises is designated on the Historic England listed buildings register. Consent is achievable, especially on a rear or flat roof out of public view, but it has to be planned in from the start rather than discovered late.
• Roof age and structure. Older roofs need a structural survey (MCS MIS 3002) to confirm they can carry the array, and pre-2000 buildings may contain asbestos that must be managed. A competent installer checks both before quoting, not after.

Where the building is not listed, a rooftop array on a non-domestic building usually proceeds under permitted development and prior approval, pitched panels projecting no more than 200mm, flat-roof panels sitting within 1 metre of the roof plane and set back from the edges. Note that both planning and the business-rates position differ across the UK: on-site solar is exempt from business rates in England to 31 March 2035, but Wales and Scotland run their own regimes, so confirm the rules that apply where you actually brew.

Funding, tax and the brewery moat

Commercial solar is special-rate plant for capital allowances (HMRC CA22335). It qualifies for the Annual Investment Allowance at 100% in year one, up to £1m, which comfortably covers virtually every brewpub project outright. It does not qualify for full expensing or the new 40% first-year allowance, so be wary of any installer who claims it does. VAT is charged at 20% and is reclaimable if you are VAT-registered; the 0% rate is domestic-only and never applies to a brewpub.

On the Climate Change Agreement, the sector's big energy-tax discount, run for brewing through the BBPA, be honest with yourself. Larger breweries qualify comfortably, but many small brewpubs may not meet the energy-intensity threshold, so check eligibility with the BBPA rather than assuming. Either way, electricity you generate and consume on-site sits outside the Climate Change Levy entirely. Our funding guide walks through the current routes and what has closed.

Talk to a specialist who knows breweries

Every brewpub is a slightly different puzzle of brew kit, cellar, kitchen and roof. The quickest way to know whether solar stacks up on yours is a proper site-specific assessment. Tell us your hectolitre output, your roof and your rough electricity spend, and we will model realistic generation, self-consumption and payback for your premises, no phone calls, no pressure, no false urgency.
