Birmingham's Group / Multi-Site Corps landscape
Birmingham hosts a substantial group colleges (multi-site corps) sector. Named providers serving the Birmingham catchment include: BMet (Birmingham Metropolitan), South & City College Birmingham, Solihull College, University College Birmingham. Combined the Birmingham Group / Multi-Site Corps sector represents a meaningful share of regional public-sector commercial electricity demand — and a correspondingly meaningful Climate Action Plan opportunity.
For Group Sustainability Director at a 3-15 campus FE corporation, the typical scoping conversation in 2026 starts with three questions: (1) what's our half-hourly meter data telling us about baseload and use pattern? (2) what's our roof area constraint? (3) what's our preferred funding stack — Salix-only or Salix + PSDS + MCA? We model all three from your specific campus context and deliver a structured feasibility report within 7 working days.
Why Birmingham Group / Multi-Site Corps solar economics are strong
Three structural factors give Birmingham Group / Multi-Site Corps a strong solar opportunity:
- Sunshine resource. Birmingham averages 1450 hours of sunshine per year — supporting around 1334 kWh annual generation per installed kWp.
- Birmingham policy context. Birmingham Council Route to Zero by 2030 + WMCA Building Energy Transformation Programme. This translates to strong council planning support for rooftop PV and an established local supply chain of MCS-certified contractors.
- FE-specific funding stack. Since the November 2022 ONS reclassification, every group colleges (multi-site corps) corporation in Birmingham has the full FE funding stack open: Salix Decarbonisation Loan, PSDS Phase 4, FE Capital Transformation Fund, T-Level Capital, and MCA decarbonisation grants where applicable.
Worked numbers for a Birmingham group colleges (multi-site corps) install

- Annual generation: approximately 1067200 kWh
- Self-consumption rate: 65% (typical for this sub-vertical and use pattern)
- Annual energy savings: approximately £173,420
- SEG export income: approximately £29,881
- Project capex: £1,350,000
- Salix-funded payback: 5.5 years
- 25-year nominal benefit: approximately £3,732,525
