Why loan amounts and structures vary

Loan quantum and structure are shaped by several clear factors:

• Project type and scale: kW of panels, number of chargers, scope of retrofit all drive cost and therefore loan size.
• Security and asset value: Asset finance and leasing rely on equipment value; larger deals often use property or contracted revenues as security.
• Business credit profile: trading history, cashflow and balance sheet strength influence lender appetite and whether unsecured finance is possible.
• Lender type: specialist green lenders, commercial banks, alternative finance and brokers each prefer different ticket sizes and documentation.
• Grants & incentives: subsidy or grant funding reduces the amount you need to borrow but lenders must see full funding plans.

Eligibility, documents & what lenders look for

What lenders commonly expect (varies by product and lender):

• Trading history and company structure (limited companies and partnerships are typical candidates).
• Project evidence: installer quotes, energy-yield or savings estimates, O&M contracts and interconnection agreements for export/import projects.
• Financials: latest accounts, management accounts, bank statements, VAT returns and cashflow forecasts.
• Site documentation: EPCs, planning permissions (if applicable), lease or ownership evidence, supplier contracts.

Document checklist (prepare these before you enquire): management accounts, 2–3 years of company accounts (if available), supplier/installer quotes, project timeline, and bank statements. If grants or incentives will contribute, have award letters ready.

Note: many lenders will accept applicants with limited trading history via specialist funds, but underwriting will reflect higher perceived risk. Get Quote Now.

Typical costs, terms and repayment options (high-level)

We cannot publish exact rates because pricing is bespoke and depends on risk, security, term and lender. Typical patterns to expect:

• Small unsecured loans: higher cost than secured asset finance.
• Asset finance & leasing: usually lower cost versus unsecured, structured around equipment life.
• Large project finance: bespoke margins tied to revenue certainty (PPAs, contracts), security and sponsor strength.

Repayment options lenders may offer include capital repayment, interest-only periods during ramp-up, seasonal or stepped repayments. All offers are subject to status, affordability checks and lender underwriting.
