The Investment That Pays You Back Whether Trade Is Up or Down
Pubs are under pressure. Energy bills have soared, margins are tight, and every pound saved goes straight to the bottom line. Solar panels offer a genuine solution — not a gimmick, but a proven way to cut electricity costs by 40-70% and lock in energy savings for the next 25 years.
Better still, pubs have energy consumption patterns that work surprisingly well with solar. Cellar cooling runs 24/7. Commercial kitchens fire up for lunch service. Glass washers, fridges, freezers, and EPOS systems all draw power throughout the day. Unlike a house that’s empty while the sun shines, a pub has significant daytime electricity demand — exactly when solar panels are generating.
This guide covers everything pub owners and operators need to know — from system sizing and costs to the complications of tenancies, listed buildings, and making the business case for solar.
Why Pubs Are Good Candidates for Solar
| Factor | Why It Helps |
|---|---|
| High baseload | Cellar cooling, fridges, freezers run 24/7 — constant electricity demand even when closed |
| Daytime kitchen use | Lunch service, food prep, extraction fans — significant daytime consumption |
| Large roof area | Many pubs have extensive roofs across main building, extensions, and outbuildings |
| High electricity costs | Commercial rates of 25-35p/kWh make savings substantial |
| Long-term occupation | Pubs don’t relocate — 25-year solar lifespan matches business permanence |
| Community visibility | Demonstrates environmental commitment to customers |
| Marketing value | “Powered by sunshine” resonates with eco-conscious customers |
| Tight margins | Energy savings go directly to profit — equivalent to significant extra sales |

Understanding Pub Energy Use
Typical Electricity Consumption
| Pub Type | Annual Electricity Use | Annual Bill (at 30p/kWh) |
|---|---|---|
| Small village wet-led pub | 15,000-25,000 kWh | £4,500-£7,500 |
| Town pub with food | 30,000-50,000 kWh | £9,000-£15,000 |
| Large pub/restaurant | 50,000-80,000 kWh | £15,000-£24,000 |
| Pub with hotel rooms | 60,000-100,000 kWh | £18,000-£30,000 |
| Large destination venue | 80,000-150,000+ kWh | £24,000-£45,000+ |
Where the Electricity Goes
| Equipment | % of Pub Electricity | When It Runs |
|---|---|---|
| Cellar cooling | 20-35% | 24/7 — constant baseload |
| Refrigeration (back bar, kitchen) | 15-25% | 24/7 — constant baseload |
| Kitchen equipment | 15-25% | Lunch prep, service, dinner prep |
| Lighting | 10-20% | Mainly evening (some daytime) |
| Glass/dish washers | 8-15% | Throughout opening hours |
| HVAC/heating boost | 5-15% | Varies seasonally |
| EPOS, music, TVs | 5-10% | Opening hours |
| Other (signage, security, etc.) | 5-10% | Various |
The Self-Consumption Advantage
Unlike a house that’s often empty during peak solar hours, pubs have substantial daytime electricity demand:
- Cellar cooling: Runs continuously, often working hardest on hot sunny days when solar output is highest
- Kitchen prep: Morning and afternoon prep for lunch and dinner service
- Refrigeration: Back bar fridges, kitchen cold storage — 24/7 operation
- Lunch trade: Full kitchen and bar operation during peak solar hours
This means pubs typically achieve 50-75% self-consumption — well above the 30-50% typical for homes. Higher self-consumption means more savings, because electricity used on-site saves 25-35p/kWh, while exported electricity only earns 4-15p/kWh.

Worked Example: Town Centre Pub
The Red Lion is a town centre pub with a busy food operation, open 7 days a week for lunch and dinner.
Current Situation
| Annual electricity use | 45,000 kWh |
| Current electricity rate | 32p/kWh |
| Annual electricity bill | £14,400 |
| Roof available | 160m² flat roof over kitchen extension + 80m² pitched main building |
Proposed System
| System size | 30kW |
| Panels | 72 x 420W |
| Location | 50 panels on flat roof (east-west), 22 on pitched roof (south) |
| Annual generation | 25,500 kWh |
| Self-consumption estimate | 70% (17,850 kWh used on-site) |
| Export | 30% (7,650 kWh) |
Financial Analysis
| Installation cost | £26,000 |
| Avoided electricity (17,850 kWh × 32p) | £5,712 |
| Export income (7,650 kWh × 8p) | £612 |
| Total annual benefit | £6,324 |
| Simple payback | 4.1 years |
| Annual electricity bill reduction | 40% |
| New annual bill | £8,688 (vs £14,400 previously) |
25-Year Value
| Total generation (25 years) | 612,000 kWh |
| Total savings (with 3% inflation) | £220,000+ |
| Net profit after system cost | £190,000+ |
| Equivalent extra revenue needed | £950,000+ (at 20% margin) |
To generate the same £190,000 profit through additional sales would require nearly £1 million in extra revenue (assuming 20% net margin). Solar delivers this profit with virtually no ongoing effort.
Freehold vs Tenancy: Who Should Install?
The pub industry’s tenancy structures create complexity around who pays for and benefits from solar.
Freehold Pubs
If you own the building outright, the decision is straightforward:
- You pay for the installation
- You receive all the savings
- You own the asset that adds value to the property
- Payback period: 4-7 years, then 18-23 years of pure profit
Recommendation: Install solar. The financial case is compelling.
Pubco/Brewery Tenancy (Tied)
For tied tenants, the building is owned by a pubco or brewery:
| Option | Who Pays | Who Benefits | Considerations |
|---|---|---|---|
| Landlord installs | Pubco/brewery | Tenant (lower bills) or shared | Landlord needs business case — may increase rent |
| Tenant installs (with permission) | Tenant | Tenant | Need written landlord consent; what happens at lease end? |
| Shared investment | Both parties | Both parties | Can work well with long leases; needs clear agreement |
If You’re a Tenant Wanting Solar
- Review your lease: Check terms around building alterations and fixtures
- Approach your landlord early: Present the business case for solar
- Propose options: Landlord-funded, tenant-funded, or shared
- Negotiate terms: If tenant-funded, what happens at lease end? Compensation? Removal?
- Get written consent: Formal permission for the installation
- Consider lease length: If you have 3 years left on the lease, tenant funding may not make sense
If You’re a Pubco/Brewery
Solar across your estate offers:
- Tenant retention: Lower energy costs help tenants succeed
- Asset value: Solar adds to property value
- ESG commitments: Demonstrates environmental leadership
- Bulk purchasing: Roll out across multiple sites for volume discounts
Major pubcos including Greene King, Marston’s, and others have begun estate-wide solar programmes.
Free-of-Tie Lease
For free-of-tie tenants with longer leases, the situation is similar to tied tenancies — negotiate with your landlord. Longer leases (10+ years remaining) make tenant-funded installation more viable.
Management Agreement
If you operate a pub under management agreement for the owner, solar decisions rest with the owner. Present the business case and encourage them to invest.
Listed Buildings
Many pubs — especially in historic town centres and villages — are listed buildings. This doesn’t prevent solar installation but requires additional approvals.
Listed Building Consent
Unlike churches (which use the faculty system), listed pubs need standard Listed Building Consent from the local planning authority:
- Pre-application advice: Contact your local planning authority’s conservation officer before formal application
- Design sensitively: Choose less visible roof areas (rear, outbuildings, modern extensions)
- Submit application: Listed Building Consent application with supporting heritage statement
- Determination: Typically 8-12 weeks; may involve Historic England consultation for Grade I/II*
Tips for Listed Pub Applications
- Use the rear: Panels on rear roof slopes are usually more acceptable than front-facing
- Target modern additions: Kitchen extensions, flat-roofed sections, outbuildings may have lower sensitivity
- Consider colour: All-black panels blend better with slate roofs
- Demonstrate reversibility: Show the installation can be removed without permanent damage
- Heritage statement: Explain minimal impact and environmental benefits
Success Rate
Many listed pubs have successfully installed solar. Sympathetic design on less sensitive roof areas is typically approved. Front-facing installations on prominent Grade I or II* listed buildings are more challenging but not impossible.
Where to Put Panels
Roof Options
| Location | Advantages | Considerations |
|---|---|---|
| Kitchen extension (flat) | Often modern build, large area, no heritage concerns | May need structural check; drainage around frames |
| Outbuildings | Separate from main building; may be unlisted | May need cable run to main building |
| Rear pitched roof | Not visible from front; standard installation | Check orientation and shading |
| Front pitched roof | Often south-facing (best output) | Heritage concerns if listed; visual impact |
| Beer garden structure | Dual purpose (shade + solar) | Planning may be needed for new structure |
| Car park canopy | Uses otherwise unproductive space; provides shelter | Higher cost; structural requirements |
Ground-Mounted Systems
If your pub has land (large beer garden, adjacent field, unused yard), ground-mounted panels avoid roof complications entirely. However:
- Planning permission usually required
- 10-20% more expensive than roof-mount
- Uses land that might have other value
- May be ideal for pubs with unsuitable roofs
Battery Storage for Pubs
Should you add battery storage to your pub solar system?
When Batteries Make Sense
- Evening-heavy trade: If most business is after 5pm, batteries store daytime solar for evening use
- Peak demand charges: Some commercial tariffs have high peak charges that batteries can reduce
- Power resilience: Batteries provide backup during outages (essential for food service)
- Low self-consumption without: If you’d only achieve 40-50% self-consumption, batteries boost this significantly
When to Skip Batteries (Initially)
- Strong lunch trade: If significant daytime use already achieves 65%+ self-consumption
- Budget constraints: Solar alone delivers better returns than smaller solar + battery
- Simple first step: Install solar now, add batteries later if needed
Battery Costs for Pubs
| Battery Size | Cost | Evening Capacity |
|---|---|---|
| 10kWh | £5,000-£8,000 | 2-4 hours of moderate pub load |
| 20kWh | £9,000-£14,000 | 4-6 hours |
| 30kWh | £13,000-£20,000 | Full evening service |
| 50kWh | £20,000-£32,000 | Extended backup capability |
EV Charging
Adding EV chargers to your pub car park is increasingly popular — and solar makes it even more attractive:
- Daytime charging: Visitors dining over lunch can charge on solar electricity
- Revenue opportunity: Charge customers for charging (or offer free as an attraction)
- Surplus use: EV chargers can absorb surplus solar that would otherwise be exported
- Destination venue: “Charge while you eat” appeals to EV drivers planning routes
Charger Options
| Type | Power | Cost (installed) | Charge Time (typical EV) |
|---|---|---|---|
| 7kW AC (single) | 7kW | £800-£1,500 | 4-6 hours for meaningful charge |
| 22kW AC (fast) | 22kW | £2,000-£4,000 | 1-2 hours |
| 50kW DC (rapid) | 50kW | £20,000-£35,000 | 30-45 minutes |
For most pubs, 1-2 x 7kW or 22kW chargers paired with solar makes sense. Rapid chargers require significant electrical infrastructure and are typically only viable for very high-traffic locations.
Funding and Tax Benefits
Capital Allowances
Solar panels qualify for valuable tax relief:
- Annual Investment Allowance (AIA): 100% first-year deduction against taxable profits (up to £1 million)
- Full expensing: For companies, 100% deduction available through March 2026
- Effect: A £30,000 solar system reduces taxable profit by £30,000 in year one
Example Tax Benefit
| Solar system cost | £30,000 |
| Corporation tax rate | 25% |
| Tax saving (AIA) | £7,500 |
| Effective cost after tax relief | £22,500 |
| Annual savings | £6,300 |
| Payback (after tax relief) | 3.6 years |
Tax relief dramatically improves the investment case — payback periods of under 4 years are achievable.
VAT
- Installation VAT: 20% standard rate for commercial properties (can’t claim 0% residential rate)
- VAT recovery: If VAT-registered (as most pubs are), you can reclaim the installation VAT
- Net effect: VAT-neutral for VAT-registered businesses
Funding Options
| Option | Details | Best For |
|---|---|---|
| Cash purchase | Pay upfront, own outright | Businesses with available capital; best returns |
| Business loan | Borrow to fund; repay over 3-7 years | Preserving cash while still owning system |
| Hire purchase | Deposit + monthly payments; own at end | Spreading cost; tax advantages remain |
| Operating lease | Rent the system; don’t own | Off balance sheet; lower savings but no capital |
| PPA | Third party installs; buy power at fixed rate | No capital available; still saves vs grid |
Making the Business Case
Return on Investment Comparison
How does solar compare to other pub investments?
| Investment | Cost | Annual Return | Payback |
|---|---|---|---|
| Solar panels (30kW) | £26,000 | £6,300 (savings) | 4.1 years |
| Kitchen refurbishment | £50,000 | Variable (revenue dependent) | 3-10+ years |
| Beer garden upgrade | £20,000 | Variable (weather dependent) | 2-5+ years |
| New EPOS system | £5,000 | Efficiency gains (hard to quantify) | Unknown |
| LED lighting upgrade | £3,000 | £800 savings | 3.7 years |
Solar offers predictable, guaranteed returns. Revenue-generating investments depend on customer behaviour; solar savings happen regardless of trade levels.
Profit Equivalent
To generate £6,000 in profit from food sales (at 20% net margin), you need £30,000 in additional revenue. To generate £6,000 from drinks (at 50% gross margin but 15% net after all costs), you need £40,000 in additional revenue.
Solar delivers the profit without the extra work, staffing, or stock.
Risk Comparison
| Factor | Solar | Traditional Expansion |
|---|---|---|
| Revenue certainty | Guaranteed (sun shines every year) | Depends on customer demand |
| Operating cost | Near zero | Staff, stock, utilities |
| Management time | None | Significant |
| Recession impact | None (savings continue) | Revenue drops |
| Lifespan | 25-30 years | Equipment varies |
Installation Process
Timeline
| Stage | Duration | Notes |
|---|---|---|
| Initial enquiry and site visit | 1-2 weeks | Installer assesses roof, usage, options |
| Quotation and design | 1-2 weeks | Detailed proposal with costs and savings |
| Decision and contract | Variable | PCC/landlord approval if needed |
| DNO application | 4-8 weeks | Required for systems over 16A per phase |
| Listed building consent (if needed) | 8-12 weeks | Only for listed buildings |
| Installation | 2-5 days | Most work is external; minimal disruption |
| Commissioning and handover | 1 day | Testing, metering, documentation |
Minimising Disruption
- Roof work: Mostly external — no need to close
- Electrical connection: May require brief power outage (1-2 hours) — schedule for quiet time
- Scaffold: Can restrict access to some areas temporarily
- Best timing: Quieter trading periods (January-February often ideal)
Maintenance
Commercial solar systems require minimal ongoing maintenance:
| Task | Frequency | Who | Cost |
|---|---|---|---|
| Visual inspection | Annual | Staff/owner | Free |
| Performance monitoring | Ongoing | Via inverter app/portal | Free |
| Professional inspection | Every 2-3 years | Solar company | £150-£300 |
| Cleaning (if needed) | As required | Window cleaner or specialist | £100-£250 |
| Inverter replacement | Year 12-15 | Solar company | £1,500-£3,000 |
Total maintenance cost over 25 years: approximately £3,000-£6,000 — a small fraction of the savings generated.
Summary

| Self-consumption | 50-75% (cellar cooling and kitchen boost this) |
| Listed buildings | Possible with consent — target less sensitive areas |
| Tenants | Need landlord agreement — consider shared benefit |
| Tax benefit | 100% AIA reduces effective cost by 19-25% |
| Key advantage | Guaranteed savings regardless of trade levels |
Solar panels are one of the most reliable investments a pub can make. In an industry where margins are squeezed and energy costs have become a major expense line, cutting 40-70% off your electricity bill delivers meaningful, predictable profit — year after year for 25+ years.
The investment case is straightforward: 4-7 year payback (often under 4 years after tax relief), then 18-21 years of savings going straight to your bottom line. No other pub investment offers such predictable, guaranteed returns with virtually zero ongoing effort.
If you’re a freeholder, install solar. If you’re a tenant, start the conversation with your landlord — the numbers make sense for both parties.
