What we do:
- Quickly match your enquiry to lenders/brokers experienced in green projects and the sectors they serve.
- Share your basic information securely with selected partners so they can offer personalised quotes.
- Keep the process simple — you receive direct contact from lenders/brokers; there’s no obligation to proceed.

Types of green & sustainability finance available
Unsecured sustainability loans
Quicker to arrange, suitable for smaller projects. Often higher rates and shorter terms. Ideal where security is not available and project payback is short.
Secured loans (property or equipment)
Lower cost options where security (commercial property or high‑value equipment) is available. Terms vary by lender.
Asset finance & green equipment leasing
Spread the cost of renewable or efficient equipment with hire purchase or leasing. Preserves cashflow and may include maintenance packages.
Invoice finance & cashflow support
Useful where supplier or installer invoices create timing gaps. Not a project loan per se, but helps with working capital during retrofit programmes.
Grants, incentives & blended finance
Where available, grants can reduce capital needs. Many lenders will structure blended solutions combining grant and loan finance — always confirm eligibility and timelines separately.
Power Purchase Agreements (PPA) & Energy Performance Contracts (EPC)
Some partners can connect businesses to PPA or third‑party funded solutions where an external operator installs kit and you buy energy — these arrangements require careful contract review.
Eligibility snapshot & what lenders look for
Each lender has its own criteria. Typical considerations include:
- Trading history and business structure (limited companies preferred)
- Turnover and profitability or realistic forecasts for the project
- Quality of supplier/installer quotes and evidence of project savings
- Environmental credentials: energy audits, EPCs, carbon reduction estimates
- Security offered (if any) and director guarantees where relevant
Fast Business Loans helps you present the right information to lenders and suggests partners who routinely assess sustainability projects.
