Can I use finance for energy efficiency upgrades or sustainability projects?

Yes. Energy efficiency upgrades, solar PV, heat pumps, EV charging infrastructure, LED lighting, insulation and other sustainability projects are well-served by UK SMB finance. Three product routes dominate: standard asset finance against the equipment, sustainability-linked loans (SLL) with rate incentives tied to emissions targets, and specific green-finance facilities from challenger banks.

Standard asset finance route. Solar PV, battery storage, heat pumps and EV chargers are all funded as hard assets through standard UK hire purchase or finance lease over 5 to 10 years. Specialist UK lenders include Aldermore, Time Finance and Ultimate Finance. Typical ticket sizes are £25,000 for a small commercial solar install to £2m+ for a multi-site sustainability programme covering solar, EV charging and building thermal upgrades.

Sustainability-linked loans. SLLs offer a small rate reduction (typically 0.10 to 0.25 percentage points across the term) if the borrower meets agreed emissions or sustainability targets. Available from larger banks including Allica Bank and Shawbrook for £500k+ facilities. The targets must be measurable, time-bound and externally verifiable; a sustainability advisor or certified consultancy is usually involved.

Green-finance specific facilities. Some UK lenders run dedicated green funds with preferential rates for net-zero-aligned spend. Oxbury Bank in agriculture, Triodos in social-purpose finance, and the green-finance arms of major banks all run these alongside standard product. For SMBs, the rate incentive is typically modest (0.25 to 0.75 percentage points) but the alignment with corporate sustainability reporting can be valuable.
