What are sustainability loans?
Sustainability loans (often called green loans or environmental finance) are business finance products designed to fund projects that reduce carbon, cut energy costs, or improve environmental performance. In the UK this covers a broad range of uses: renewable energy installations, energy-efficiency improvements, electric vehicle (EV) fleet upgrades, low-carbon equipment and circular-economy investments.
Fast Business Loans acts as an introducer: we collect project and business details to match you with the most suitable brokers and lenders. We do not lend money or provide regulated financial advice — instead we speed up your search and increase the chance of a good match.
Typical projects funded
- Solar PV arrays and battery storage for commercial premises
- Heat pumps, biomass boilers and low-carbon heating
- EV chargers and electric vehicle fleet financing
- LED lighting, insulation and building fabric upgrades
- Energy Management Systems (EMS) and smart metering
- Recycling and waste-reduction equipment
- Process changes that reduce energy intensity or emissions
Why UK businesses use sustainability finance in 2025
Rising energy costs, net-zero commitments from customers and suppliers, and attractive payback periods mean many businesses are investing in green projects now. For many firms the decision is commercial — lower operating costs and potential tax benefits — and increasingly strategic: customers and buyers expect demonstrable sustainability actions.
Benefits of sustainable investment
- Lower running costs and predictable energy bills
- Improved asset value and business resilience
- Access to grants, tax reliefs and blended finance in some cases
- Stronger procurement positioning with large buyers demanding ESG data

Costs, terms & considerations
Pricing for sustainability loans depends on project type, credit profile, security and the lender. Typical features:
- Interest rates vary widely; some lenders offer preferential terms for verified green projects, while others price similarly to conventional finance.
- Repayment terms can range from 1–3 years for working capital to 5–15+ years for long-life assets and energy infrastructure.
- Security may be required (company or director guarantees, charge on property or assets).
- Grants and capital allowances may improve project economics — brokers can help blend funding sources.
Fast Business Loans does not provide financial advice; matched brokers and lenders will provide bespoke terms and full disclosure of costs.
Case study snapshot
Manufacturing business — roof-mounted solar PV and battery storage
A mid-sized manufacturer estimated the project at £180,000. Fast Business Loans introduced the company to two specialist brokers. One broker arranged asset finance and coordinated a small grant application. Funding mix: 60% asset finance, 20% grant, 20% company funds. Payback from reduced electricity costs was projected at 4.5 years; the business gained energy price certainty and immediate cashflow improvement. The matched broker handled lender negotiations and installation contracting.
Why sustainability-focused lenders value Fast Business Loans introductions
Lenders and specialist brokers appreciate high-quality introductions that include clear project detail and credible documentation. Our benefits to them — and to you — include:
- Sector-specific matching that reduces wasted time for both parties.
- Pre-filtered enquiries that include project cost and supplier information.
- Faster turnaround from initial contact to indicative offer.
