What is the best business finance for a UK solar or renewables installer?
It depends on what you're paying for. For panels, inverters and charge points, asset finance secured on the kit is the usual route, and Novuna is the lender on this list that names renewables as a specialism. For a larger capex project, Allica is the challenger bank on the list. For the gap between buying stock and getting a subsidy or stage payment, iwoca's shorter-term working capital is the option.
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?
As recorded in our lender reviews: Novuna Business Finance: bespoke pricing, quoted at offer. Allica Bank: business loans 9.90% to 13.75% interest; other products quoted per deal. iwoca: from 1.5% per 30 days. Lenders price each case individually, so confirm the cost on a real quote.
How fast can a renewables business get a decision?
As recorded in our lender reviews: Novuna Business Finance: not published; typical of corporate asset lenders. Allica Bank: money in days on business loans; longer for larger facilities. iwoca: same day to 24 hours. Timings are the lenders' own or typical figures and depend on how complete your application is.
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.
