UK Solar Carport Finance Options
Four primary commercial solar carport finance routes in the UK — direct capital, asset finance, PPA, and Salix Recycling Fund. Each suits different buyer profiles. Decision framework + economics worked through below.
The four routes at a glance
| Route | Capex needed | Cashflow Y1 | 25-yr NPV | Best for |
|---|---|---|---|---|
| Capital purchase | 100% | -£330k (£400k carport) | ~£2.2m | Tax-paying companies with surplus capex |
| Asset finance | 0-10% | +£95k | ~£1.95m | Cashflow-sensitive operators |
| PPA | £0 | +£105k | ~£1.4m | Charities, non-tax-payers, balance-sheet-sensitive |
| Salix Recycling Fund | £0 (0% loan) | +£42k | ~£3.1m | UK public sector (NHS, schools, councils, unis) |
Capital purchase delivers the highest 25-year NPV but requires the cash upfront. PPA and asset finance trade NPV for cashflow. Salix is the public-sector golden ticket — 0% interest and AIA-equivalent benefit. Choose based on your capital availability, tax position, ownership preference, and 25-year operational outlook.
