Solar Carports for Business Parks
Shared-tenant business parks turning under-utilised tarmac into a Scope 2 emissions reduction and an estate-wide amenity.
Sector economics
UK business parks — typically 50-300 unit, mixed-tenant estates — have substantial shared car parking that is rarely PV-developed. The estate manager or freeholder typically owns the car park, with rents flowing through service charges. A solar carport over a business park car park is a real estate income enhancement opportunity, monetised either as cheaper electricity to tenants or as a chargeable service-charge line item.
Recent Business Parks & Office Estates Case Study
A 4-block business park in Slough with 480 shared parking bays installed a 720 kWp solar carport in 2024. The carport supplies behind-the-meter solar to 14 office tenants via a service-charge ring-fenced supply tariff. Tenants pay 28p/kWh (vs 47p/kWh grid retail) — 40% saving. Estate landlord recovers the full carport capex over 6.2 years through the service-charge mechanism.
Sector-Specific Design

- Cabling routed to estate-wide ring main, with sub-metering per tenant
- Pre-EV-ready (DC stubs at every 4th column) for staggered EV rollout

- Site-wide monitoring portal with tenant access
Standards & Frameworks
- RICS Service Charge Code (5th edition) for cost recovery transparency
- Estate-level Energy Performance Certificate (EPC) improvement
- Tenant fit-out lease compatibility (PV doesn't trigger dilapidations)
- DNO G99 plus G100 export limit for multi-tenant export sharing
- TCFD-aligned reporting on Scope 2 reduction for landlords
How to Pay for It
Business park carports rarely access public sector grants but stack well with: (1) Asset finance at favourable rates (carports are tangible asset-backed), (2) Private PPA — particularly when tenants are co-signatories, (3) Real Estate Solar Capital Allowance for landlord buyers.
