Solar Panels for Business Premises UK — Office, Industrial & Retail

From sub-50 kW office rooftops to 2 MW factory installations — commercial solar PV adapts to every UK business premises type. The economics, planning route, and compliance threads vary by property type. This is the cross-property guide.

By property type

UK business premises break into clear PV-economics tiers:

  • Office buildings (B1): 50–300 kW typical. Daytime occupancy, IT load. 4–6 year payback.
  • Factories (B2): 100 kW–2 MW. Process baseload. 3–5 year payback.
  • Warehouses (B8): 250 kW–5 MW. Large clear-span roofs. 3–5 year payback.
  • Retail / shopping parks (A1): 30–200 kW. Lease alignment matters. 5–7 year payback.
  • Hotels (C1): 50–300 kW. 24/7 demand profile. 4–6 year payback. See dedicated hotel guide.
  • Schools (D1): 50–300 kW. Term-time load profile favours PPA. See dedicated school guide.

Common considerations across all property types

Regardless of property type, four threads always apply: structural roof survey, G99 DNO grid connection, MCS Commercial certification, and a financing route (capex / asset finance / PPA / loan). What changes is the load profile, the roof type, and the tenant-vs-landlord ownership dynamic.

Tenant vs owner-occupier

Owner-occupiers have the cleanest install path: full capex, full benefit. Tenants on long leases (10+ years remaining) can install with landlord consent; tenants on short leases typically use PPA structures with rights transferable on lease assignment. Landlords often install centrally and credit savings via reduced service charge. See our dedicated tenant vs landlord guide.
