Quick answer: who is generally eligible?

Most small and medium-sized UK limited companies, LLPs, charities and social enterprises working on demonstrable sustainability projects may be eligible for sustainability loans from specialist lenders or brokers. Eligibility depends on the project type (solar, EV chargers, heat pumps, etc.), trading history, cashflow and the evidence you can provide about savings/outputs.

We don’t lend money and we don’t give financial advice. We introduce businesses to lenders and brokers who can provide finance.

Who can apply: business & legal eligibility

Before applying, check these common business-level requirements. Individual lenders vary, so this is a summary of what you’ll usually encounter.

• Business type: UK-registered limited companies and LLPs, charities and social enterprises. (We do not arrange loans for sole traders or professional practices.)
• Location: Projects and businesses operating in the UK.
• Trading history: Many lenders prefer at least 6–12 months trading, though specialist lenders can consider newer businesses with confirmed contracts, grant awards or robust forecasts.
• Minimum loan size: Our partners typically arrange sustainability finance from around £10,000 upwards depending on the product and lender.
• Right to act: Directors or authorised signatories must provide ID and proof of authority to enter agreements.

Project eligibility: what counts as a sustainability project?

Lenders have different appetites but commonly accept projects that deliver measurable energy savings, reduced carbon emissions or renewable energy generation. Typical qualifying projects include:

• Renewable energy generation: rooftop or ground-mounted solar PV, small wind, and battery storage.
• Energy efficiency upgrades: LED lighting, insulation, building fabric improvements, HVAC controls.
• Low-carbon heating: air-source and ground-source heat pumps, biomass boilers where appropriate.
• EV infrastructure: workplace or public EV charging points and associated electrical upgrades.
• Fleet decarbonisation: purchase or lease of electric vehicles and charging networks.
• Circular-economy investments: equipment or systems that demonstrably reduce waste and energy use.

What lenders often want to see:

• Performance estimates or energy savings forecasts (kWh, CO2 or £ savings).
• Installation by accredited suppliers (e.g., MCS, NICEIC or recognised trade accreditation relevant to the technology).
• Supplier quotes, technical specifications and warranties.
• Planning permission, landlord consent or wayleaves where required for the project.

For more detail on qualifying projects and finance types, see our page about sustainability loans.

Financial & credit requirements lenders commonly check

Lenders evaluate the business’s ability to repay and the project’s risk profile. Typical checks include:

• Turnover & profitability: Lenders review recent accounts, turnover and margins. Required turnover thresholds vary by lender and product.
• Cashflow: Forecasts showing the project’s impact on operating cashflow, especially for larger CAPEX projects.
• Credit history: Business and director credit searches are common. Some specialist lenders accept adverse credit but usually at different pricing.
• Security & collateral: Smaller green loans may be unsecured; medium-to-large CAPEX often needs asset security, debentures or personal guarantees.
• Deposit or co-funding: Some lenders require a contribution from the business or evidence of grant funding/match funding.
• Loan term & size: Terms vary — short-term working-capital green loans through to long-term amortising finance for major installations.

Submitting an initial enquiry to UK Business Loans will not affect your credit score. Lenders may perform formal credit checks later if you proceed with an application.

What documents you’ll usually need

Preparation speeds approvals. Here’s a practical checklist to gather before you submit an enquiry or when a lender requests full paperwork.

• Company details: company name, registration number, registered office, SIC code and VAT registration (if applicable).
• Accounts: filed accounts for the last 1–3 years, or management accounts for newer companies.
• Bank statements: business bank statements for the last 3–6 months.
• Director ID: passport or UK driving licence and a recent proof of address.
• Project paperwork: supplier quotes, technical specifications, installer accreditations (MCS, NICEIC, etc.), warranties and expected performance data.
• Energy reports: EPCs, feasibility studies or energy savings estimates where available.
• Existing finance: schedule of current debts, hire purchase agreements and any secured facilities.
• Business plan/forecasts: for larger projects, a business plan and 12–36 month cashflow forecast help lenders assess affordability.

How UK Business Loans helps you meet lender requirements

UK Business Loans is a specialist matching service. We do not lend or give regulated advice; instead we:

• Take a short, targeted enquiry about your business and project.
• Match you quickly to lenders and brokers who regularly finance sustainability projects.
• Pass on only the information relevant to each match so lenders can provide a tailored response.
• Help you compare multiple offers and next steps so you can choose the right partner.

Our service is free to businesses. Data is shared only with selected lenders/brokers we believe are appropriate for your request and handled securely. Start a Free Eligibility Check and get matched — Get Quote Now.

Typical application process & timescales

1. Complete the short enquiry form (around 2 minutes) — we use this to pre-match your business.
2. Pre-match & selection — we identify lenders/brokers who suit your project (often within hours).
3. Broker/lender contact — a provider contacts you to discuss and request supporting documents (24–72 hours typical).
4. Formal application & technical checks — can take 1–6 weeks depending on project complexity and surveys/technical reports required.
5. Offer, acceptance and drawdown — once an offer is accepted, funds and installation scheduling follow the lender’s processes.

Smaller working-capital or equipment green loans are usually quicker; major installations requiring surveys or public grants will naturally take longer.

Common reasons applications are declined — and how to fix them

• Missing or weak project documentation — fix: obtain accredited installer quotes, performance estimates and installer accreditations.
• Poor cashflow or weak affordability — fix: provide detailed forecasts, reduce requested amount or increase deposit.
• Incomplete permissions — fix: secure planning, landlord consent or wayleaves before applying.
• Unsuitable technology or unaccredited installer — fix: choose accredited suppliers or provide additional warranties and maintenance contracts.
• Adverse credit history — fix: discuss specialist lenders via our panel, or improve financial position before reapplying.
