Devolved Nation Business Energy Support for business solar
May apply to your businessIf your business is in Scotland, Wales or Northern Ireland, there are dedicated SME loans and grants for solar that businesses in England cannot access.
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: interest-free (0%) unsecured loan up to £100,000 for energy efficiency / renewables, plus cashback grant up to £30,000 - but note the cashback is 75% up to £20,000 for energy-efficiency measures and 75% up to £10,000 for renewable HEAT, and does not clearly list standalone solar PV among cashback-eligible measures (solar PV is generally funded via the loan, not the cashback). 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. Figures are indicative and subject to funds remaining.
