Solar Panels for Offices
Multi-tenant office and business-park solar with sub-metering, ESG reporting and split-tenant cost recovery built in.
Quick Answer
- Typical size: 30–250 kWp on flat or low-pitch office roofs
- Typical project value: £22k–£170k installed (ex-VAT, before tax relief)
- Year 1 saving: 22–40% off baseline electricity bill
- Payback: 4.5–6.5 years on capex; with battery 4.0–5.5 years
- MEES 2030 ready: EPC uplift typically D→C or D→B, securing letability post-2027/2030
- Lead time: 10–16 weeks survey → commissioning
Office solar economics are uniquely shaped by tenancy. Most UK offices are tenanted on FRI leases, the service charge model means recovery of utility cost is via per-square-foot allocation, and ESG reporting expectations are now standard on any property above 10,000 sq ft. KMM has installed solar on owner-occupied offices and multi-tenant business parks across the UK.
Where the economics actually work
Tenant cost recovery
We work with the property's service-charge accountant to design a billing mechanism that allocates solar-generated kWh to tenants on a fair basis, typically per-square-foot.
ESG / GRESB reporting
Every system we install includes a tenant-accessible monitoring dashboard with the carbon and kWh data formatted for GRESB and CRREM reporting.
Roof acoustics
Office roof PV needs more attention to acoustic isolation than warehouse PV, because office occupants notice rooftop noise. We use vibration-isolated inverter mounting on every office install.
Battery for outage resilience
For HQ-style sites where IT continuity matters, we pair the solar with battery and an automatic transfer switch to provide ride-through for short outages.
