Solar Panels for Pubs, Restaurants & Hospitality UK (2026)
Quick Answer
Solar for UK pubs, restaurants & hospitality typically costs £12,000–£36,000 for a 10–40 kW system, saving £2,000–£7,500/year and paying back in 5–7 years. Solar PV qualifies for the Annual Investment Allowance (100% first-year tax relief up to £1M).
Costs verified April 2026 for UK commercial market. Site-specific quotes vary materially.
UK pubs, restaurants & hospitality increasingly install solar to cut what is usually the second or third largest operating cost: electricity. This guide covers system sizes that suit the sector, realistic payback, tax treatment, and the specific considerations that make solar work (or not) for pubs, restaurants & hospitality.

| Tax relief | Annual Investment Allowance (100% up to £1M) |
Why Solar Works for Pubs, Restaurants & Hospitality
Hospitality venues have high continuous electrical load: refrigeration runs 24/7, kitchens run lunch and evening service, HVAC and lighting span operating hours. Daytime load (prep, lunch, refrigeration) matches solar generation well; evening load is served by grid or battery.
- Refrigeration is a constant base load — solar generation directly offsets it
- Lunch service peaks 11am–3pm, aligning with peak solar production
- Rooftop space on extensions, outbuildings, and kitchens often sits unused
- Pub gardens and car parks suit ground-mounted arrays or solar carports
- Rising energy costs disproportionately affect low-margin hospitality — solar protects margin
- Sustainability messaging is increasingly valuable for independent venues
Sector-Specific Considerations
- Listed buildings and conservation areas: common for historic pubs and restaurants — may restrict front-of-building installations
- Tenant vs landlord installations: pub companies and breweries often own freehold; need agreement on who pays and who benefits
- Existing electrical capacity: older venues may need a three-phase upgrade before larger systems are viable
- Evening-heavy load profile makes batteries unusually valuable — time-shift solar into dinner service
- Extraction fans, commercial ovens, and pizza ovens: check which run on electric vs gas
Typical System Sizing
Most pubs, restaurants & hospitality installations fall in the 10–40 kW range. For detailed cost, output and payback data at your target size, see our 15KW solar system cost guide.
Commercial solar in the UK generally costs £800–£1,000 per kW installed at the smaller end (sub-50kW) and £600–£800 per kW at industrial scale (250kW+). Site complexity — roof condition, access, switchgear upgrades, DNO constraints — drives variation more than panel or inverter brand.
Tax Treatment & Finance
- Annual Investment Allowance (AIA): 100% first-year tax relief on qualifying capital expenditure up to £1 million per year. Solar PV qualifies.
- VAT: commercial solar is not zero-rated (unlike residential). Standard 20% VAT applies and is reclaimable for VAT-registered businesses.
- Capital allowances beyond AIA: 50% first-year allowance on solar for limited companies exceeding the £1M AIA cap.
- PPA / rooftop lease: available as an alternative to outright purchase — a third party owns and maintains the system; you pay a below-grid rate for the electricity generated.
- Asset finance: widely available; typical structures deliver positive cashflow from month one.
DNO Approval
Most commercial installations above 11.04kW on three-phase supply (or 3.68kW per phase on single-phase) require a G99 DNO pre-approval. Timelines are typically 6–9 weeks. See our DNO application guide for full detail.
Frequently Asked Questions
How much do solar panels cost for a pub or restaurant?
A typical independent pub or restaurant installs a 10–20kW system at £12,000–£18,000 installed. Larger gastropubs and multi-site operators often go 30–40kW. Payback is 5–7 years at current electricity prices.
Is a battery worth it for hospitality?
Often yes — evening service is the revenue-generating period, and electricity prices peak 4–9pm. A battery lets you store midday solar and discharge into dinner service, dramatically improving the savings.
Can pub tenants install solar?
Only with landlord consent. Pub companies increasingly have programmes for solar on tied estates, but the terms vary. Free-of-tie and freehold operators have straightforward installation rights.
Does solar help with a listed pub building?
It can be challenging. Many historic pubs are listed, and front-of-building solar often gets refused. Ground-mounted arrays in pub gardens, or installations on extensions and outbuildings, are usually more successful.
