Why sustainability finance matters now

Energy costs, regulatory changes and customer expectations are pushing businesses towards lower-carbon operations. Investing in sustainable infrastructure reduces operating costs, supports compliance with evolving regulations and often improves access to contracts and customers who prioritise ESG credentials. But green upgrades usually need upfront capital — that’s where targeted sustainability finance comes in.

What are sustainability business loans?

Sustainability business loans (often called green loans) are commercial finance products designed to fund projects that reduce carbon emissions, improve energy efficiency or otherwise deliver environmental benefits. They can be secured or unsecured, short or long term, and may come as standard business loans, asset finance, leasing or project-specific facilities. Grants and incentive schemes sometimes complement loans, but loans remain the primary way to finance larger CAPEX projects.

We introduce lenders and brokers for a wide range of sustainability projects. Typical examples include:

Sectors we commonly help: manufacturing, hospitality, retail, logistics, agriculture, healthcare and professional services seeking sustainability upgrades.

Types of sustainability funding we can introduce

Depending on the project and your business profile, lenders/brokers may propose:

• Business loans: unsecured or secured finance for CAPEX and working capital.
• Asset finance & leasing: fund equipment with repayment tied to the asset.
• Project finance: for larger installations with bespoke structures.
• Invoice & cashflow finance: to preserve cash while investing.
• Refinance solutions: restructure existing debt into a green-focused facility.

Typical facility sizes start from around £10,000 and can extend to several million, depending on the partner and project complexity. Terms, rates and security requirements vary by lender — our matching process helps you find those most likely to offer suitable terms.

Eligibility snapshot — what lenders look for

While each lender has its own criteria, common factors include:

• Company structure and trading history (incorporated businesses typically preferred).
• Annual turnover and profitability or credible cashflow forecasts.
• Project costs, supplier quotes and expected energy savings/ROI.
• Management experience and sector understanding.
• Any collateral or assets available if the facility requires security.

Even if you have imperfect credit history, some specialist brokers and alternative lenders work with businesses across a range of credit profiles. The best way to know is to submit an enquiry for a Free Eligibility Check: Get Started — Free Eligibility Check.

Preparing for a successful green finance enquiry

Before you speak to lenders, gather the essentials. This will speed up matching and improve quote quality.

• Project summary: scope, expected costs and timelines.
• Supplier quotes: at least one or two detailed estimates for the work or equipment.
• Energy data / Baseline: current consumption and expected savings (kWh or £).
• Forecasts: brief financials or cashflow projection showing how you’ll repay.
• Ownership & company details: basic company registration, turnover, contacts.

Many brokers can help refine project paperwork and provide assistance with supplier introductions or ROI modelling once you’re connected.

UK sustainability funding landscape — opportunities & responsibilities

The UK offers a mix of private finance, commercial incentives and occasional government support for net-zero projects. Grants and local authority schemes can reduce project cost, while commercial lenders provide the capital for larger investments. Responsible borrowing matters: choose a finance structure that your business can sustain and that aligns with projected savings. Where in doubt, ask the broker or lender for clarity on repayments, fees and long-term impact.
