Frequently Asked Questions
How much does commercial solar cost for an office building?
Commercial solar for office buildings costs £750–£1,050 per kWp installed in 2026. Office solar installations typically run 30–150kWp (enough for 1,000–5,000m² of floor area). A 50kWp office system costs £37,500–£52,500 and saves £8,400–£11,200 per year at 30p/kWh. Office self-consumption rates of 55–70% (daytime-only occupancy) give payback of 4–5.5 years, falling to 3–4 years after AIA tax relief.
Can solar panels improve an office building's EPC rating?
Yes. Commercial solar panels improve an office building's EPC rating by reducing the calculated energy demand. Under MEES 2030 regulations, commercial properties must achieve EPC rating B or above by 2030 to be legally lettable. Solar generation directly reduces the asset's operational carbon rating. For offices at EPC C or D, a correctly-sized solar system combined with LED lighting and HVAC optimisation can often achieve EPC B without expensive fabric upgrades. We provide MEES impact assessments with our office solar quotations.
Do landlords or tenants pay for office solar?
This depends on the lease structure. For owner-occupied offices, the cost and benefit are straightforward. For let offices, there are three models: (1) Landlord-funded with costs recovered via service charge; (2) PPA/virtual PPA — landlord installs, tenant buys power at a fixed rate below grid price (split-incentive solution); (3) Green lease clauses requiring tenant contribution to solar installation as a sustainability condition. We advise on all three models and can draft the commercial framework for review by your solicitor.

Quick Answer
Do solar panels improve the EPC rating of a commercial office building?
Yes — solar PV directly reduces delivered energy consumption (kWh/m²/year), which is the primary input to the SBEM/EPC calculation. A 50kWp system on a 2,000m² office typically improves EPC by 4–8 rating points. MEES compliance (minimum E-rating from April 2023, C-rating proposed for 2027) makes solar a strategic investment for landlords. Cost: a 50kWp office system runs £35,000–£50,000 installed; payback 5–8 years.
Why Office Buildings Need Solar Panels Now
Two regulatory drivers are creating urgency around office solar installations in 2026:
MEES (Minimum Energy Efficiency Standards)
Commercial offices must achieve a minimum EPC E-rating to be let — since April 2023 this applies to existing leases, not just new ones. The government has proposed a C-rating minimum for 2027 and a B-rating minimum for 2030. Solar PV is one of the most cost-effective routes to EPC improvement, particularly when combined with LED lighting and building energy management systems. Landlords with D or E-rated office portfolios need to act now.
Net Zero Commitments & ESG Reporting
Office occupiers — particularly in financial services, legal, consulting, and tech — are increasingly requiring Scope 2 emission reductions from their landlords as part of tenancy negotiations. Buildings with solar PV and strong EPC ratings command higher rents and lower vacancy rates. See our ESG solar strategy guide and MEES compliance guide.
Office Solar Sizing Guide
| Office Size | Roof Area Needed | Recommended Solar | Annual Saving | EPC Improvement |
|---|---|---|---|---|
| Small office (<500m²) | 100–300m² | 10–30kWp | £2,500–£7,500 | 2–4 points |
| Mid-size (500–2,000m²) | 300–800m² | 30–80kWp | £7,500–£20,000 | 4–8 points |
| Large office (2,000–5,000m²) | 800–2,000m² | 80–200kWp | £20,000–£50,000 | 8–15 points |
| Business park / campus | 2,000m²+ | 200kWp+ | £50,000+ | Custom calculation |
