What is the best business finance for a UK solar or renewables installer?
Novuna Business Finance names renewables directly among its asset-finance specialisms, the clearest named fit for installation plant, panels and charge points. Allica Bank covers capex-heavy renewables businesses more broadly, and iwoca fills the working-capital gap between buying stock and receiving subsidy or stage payments.
How is renewables installation equipment usually financed?
Hire purchase or lease against the panels, inverters and charge points themselves, which lowers the eligibility bar versus an unsecured loan. Working capital separately bridges the timing gap between paying for materials and receiving a subsidy or stage payment.
What rate should an energy or renewables business expect?
Allica Bank prices term loans and asset finance from 7.99% APR. iwoca prices from 2% per month on drawn balance. Novuna quotes bespoke, case by case, with no published headline rate.
How fast can a renewables business get a decision?
iwoca decides same day to 24 hours for working capital. Allica Bank takes 5 to 10 business days for asset finance. Novuna does not publish a standard decision time.
What stops a renewables business getting finance?
Heavy dependence on a single subsidy or scheme, and newer technology with a thin resale track record, are the most common reasons a lender hesitates. MCS certification status is also weighed closely.
