What Counts as a Sustainability Business Loan?

Sustainability business loans are forms of commercial finance used to fund projects that reduce environmental impact, improve energy efficiency or support a transition to low-carbon operations. Typical qualifying projects include:

• Renewable energy installations (e.g., rooftop or ground-mount solar PV).
• Energy-efficiency upgrades (LED lighting, insulation, modern HVAC systems).
• Low-carbon heating (heat pumps, biomass systems) and building fabric improvements.
• Electric vehicle charging infrastructure or fleet electrification.
• Production process upgrades that reduce waste, increase recycling or enable circular-economy models.

Eligibility and terms depend on the lender and project type. For sector-specific green funding guidance and examples, see our sustainability business loans resource.

Funding Routes We Can Introduce You To

Fast Business Loans connects you with brokers and lenders offering a range of green finance routes. Below are common options and when they make sense.

Green Term Loans & Revolving Credit

Best for: one-off projects or staged investment programmes.

• Pros: flexible repayment terms, single repayment profile tailored to project cashflows.
• Cons: may require company security or personal guarantees on larger facilities.

Sustainable Asset & Equipment Finance

Best for: financing physical assets (EVs, renewable equipment, energy-efficient machinery).

• Pros: secured on the asset, preserves working capital; usually structured as hire purchase or leasing.
• Cons: asset valuation and useful life affect terms; disposal conditions may apply.

Invoice & Cashflow Support for Green Projects

Best for: businesses awaiting payment while delivering sustainability contracts or retrofit programmes.

• Pros: speeds cashflow without long-term debt; useful for installers and service providers.
• Cons: fees and advance rates vary; not suitable for long-term capex funding.

Grants, Incentives & Blended Finance

Best for: projects that can combine grant funding, tax incentives or supplier finance with a loan.

• Pros: reduces net cost and improves project IRR; brokers on our panel can help identify and blend funding sources.
• Cons: grants are competitive and often have strict eligibility and reporting requirements.

Typical Eligibility Criteria

While each lender sets its own rules, brokers commonly review:

• Company type and trading history (established SMEs and growing companies).
• Turnover and profitability or demonstrable project cashflow.
• Project feasibility and projected energy savings or revenue uplift.
• Security available (asset-backed vs unsecured facilities) and director/co-signatory profiles.

Preparing a Strong Green Finance Application

Good preparation speeds approval. Focus on three areas:

Financial Documentation Checklist

• Latest company accounts, management accounts and business bank statements.
• Cashflow forecasts showing project impact on earnings.
• Details of existing borrowing and any outstanding facilities.

Sustainability Evidence & Impact Metrics

• Quotes and specifications from suppliers/contractors.
• Estimated energy savings, carbon reduction figures or payback modelling.
• Technical reports or EPC where applicable.

Project Planning & Technology Due Diligence

• Project timeline, installation milestones and revenue assumptions (if applicable).
• Warranties and maintenance plans for installed equipment.

Costs, Rates & Repayment Considerations

Rates and fees depend on the lender, facility type, security and credit profile. Typical considerations:

• APR ranges vary by product; asset finance is often priced differently to unsecured loans.
• Some lenders offer preferential terms for proven energy-saving projects or where grants reduce the loan-to-cost.
• Always check arrangement fees, early repayment charges and any deferred repayment structures.
