What counts as a sustainability business loan?

Sustainability business loans cover finance used to reduce environmental impact, lower energy costs or enable low‑carbon products and services. Typical project examples include:

• Solar PV installations, battery storage and renewable generation
• EV fleet purchases and charging infrastructure
• Heat pumps, insulation and energy-efficiency retrofits
• Process improvements to lower waste and water use
• Equipment for circular-economy activities

Projects can range from smaller upgrades to large capital investments. For a deeper overview of green funding by sector, see our sustainability business loans industry guide at sustainability business loans.

Funding options for sustainable projects

Term loans & sustainability-linked loans

Term loans provide lump-sum capital over a fixed period. Sustainability-linked loans may offer pricing incentives linked to agreed ESG KPIs (for example, energy reduction or emissions targets). Lenders will set terms and may require reporting on KPI progress.

Asset & equipment finance

Asset finance lets you acquire solar panels, EVs, heat pumps or manufacturing equipment while spreading cost over the asset life. This preserves working capital and often matches repayments to savings or revenue generated by the asset.

Invoice & working capital support

Invoice finance and short-term facilities bridge cashflow while you implement upgrades or wait for incentives to arrive. These products keep operations running and allow staged project delivery.

Grants, incentives & complementary funding (information only)

Grants and government incentives can reduce project cost but are often competitive or time-limited. Our introducers can help broker blended funding packages that combine loans with grant funding where suitable.

3. Selected partners contact you directly to discuss options and request documents if needed.

Benefits of investing in sustainability now

Investing in sustainability can provide immediate and long-term business advantages:

• Lower operating costs through reduced energy and fuel use
• Improved resilience to energy price volatility
• Stronger tender performance where supply-chain ESG requirements exist
• Enhanced brand reputation and attraction of talent
• Access to potential tax reliefs, incentives or cost-savings

Many projects pay for themselves over time through reduced bills and higher efficiency. Lenders will assess project economics alongside carbon benefits when structuring finance.

How UK lenders are evaluating ESG projects in 2025

Lenders increasingly look for clear, measurable outcomes. Useful preparation includes:

• Simple baseline metrics (energy use, emissions) and realistic targets
• Supplier quotes and equipment specifications
• Evidence of expected savings and lifetime costs
• Relevant certifications where applicable (e.g., ISO 14001)

Lenders may favour projects with robust ROI, credible installers and demonstrable carbon reduction. We introduce you to partners who can advise on structuring the finance to reflect these trends.

Transparent costs & responsible borrowing

Fast Business Loans introduces you to providers; lenders determine the interest rates, fees and terms. Typical costs to expect may include arrangement fees, interest, and potential security requirements. Before agreeing to finance, review the full terms from the lender and ensure repayments are affordable given possible project overruns or delays.

Information on this site is general guidance only — Fast Business Loans is an introducer, not a lender or financial adviser.

Timeline: from enquiry to funding

Typical timeframes:

• Initial contact after enquiry: hours to 1 business day
• Detailed review & lender shortlist: 2–7 days
• Formal offers & documentation: days to several weeks (depending on complexity)
• Drawdown: following completion of lender conditions

Smaller, unsecured facilities are the quickest; project or asset-backed finance takes longer due to valuations and contract checks.
