Devolved Nation Business Energy Support for business solar
May apply to your businessIf your business is in Scotland, Wales or Northern Ireland, the devolved governments run their own business energy loans and grants: the Welsh green business loan lists solar PV, while Scotland's interest-free SME loan is not taking new solar PV applications.
Who qualifies
Depends on nation. SCOTLAND (Business Energy Scotland SME Loan): Scottish SMEs, not-for-profits and charities trading 12+ months, meeting the EU SME definition. WALES (Development Bank of Wales / Business Wales Green Business Loan Scheme): Wales-based limited companies, sole traders or partnerships trading 2+ years with at least one set of filed accounts. NORTHERN IRELAND (Invest NI Energy Efficiency Capital Grant and NISEP): NI businesses investing in energy efficiency and onsite renewables including solar PV. Businesses in England do NOT qualify for any of these.
How much it is worth
SCOTLAND: an interest-free loan of £1,000 to £130,000 over 8 years for energy efficiency and renewable heat, plus cashback of up to £30,000 per business (75% up to £20,000 for efficiency measures and 75% up to £10,000 for heat pumps, biomass or solar thermal); the SME Loan is not accepting new applications for solar PV projects (checked 6 October 2026). WALES: Green Business Loan Scheme offers discounted-rate loans (part of a ~£10m fund over 3 years) with solar PV explicitly eligible; plus an energy audit grant of up to 50% of costs to a maximum of £10,000. NI: Invest NI Energy Efficiency Capital Grant up to £150,000 covering onsite renewable generation; NISEP provides around 20% grant support toward technologies including solar PV.
