Commercial & Offices
Offices and retail carry steady daytime electricity demand and often sizeable flat roofs — a strong match for on-site solar that offsets consumption exactly when power is most expensive.
Offices, retail parks and mixed-use estates combine two useful things for solar: large, often flat roof areas, and electricity demand that peaks during the working day when panels generate most. That alignment means a high share of generation can be used on site, offsetting power at the point it costs the most.
The complications are commercial rather than technical — who pays and who benefits across a lease, how roof warranties and service charges are handled, and how the works fit around tenants. We model the economics and structure the arrangement so the investment lands with the party that gains from it.
Challenges we help with
- Landlord–tenant split incentives over who pays and who benefits
- Roof warranties and lease terms that complicate installation
- Service-charge and EPC implications across let space
How we help
- Model self-consumption against your daytime load and tariff
- Structure landlord/tenant or service-charge arrangements, and an on-site PPA where it fits
- Fold the works into planned roof and lease events

Who benefits if we let the building to tenants?
That depends on the lease and metering. We model landlord, tenant and service-charge options — and, where it fits, an on-site PPA — so the party paying for the system is the one seeing the benefit.
Will solar affect our EPC?
On-site generation generally improves a commercial EPC, which can matter for MEES lettability and asset value. We factor it into the case.
