What are sustainability loans?

Sustainability loans are commercial finance products designed to help businesses invest in projects that reduce energy use, lower carbon emissions or support circular economy goals. Typical uses include:

• Solar PV and renewable energy installations
• Energy-efficiency retrofits (LED lighting, insulation, heat pumps, HVAC)
• Electric vehicle (EV) fleets and charging infrastructure
• Waste reduction equipment and recycling systems
• Sustainable building upgrades and low-carbon materials

These loans come in many forms — unsecured business loans, asset finance, equipment leases, hire purchase, or loans secured against property or assets. Loan sizes we typically help source start from around £10,000 and can rise to much larger sums for major projects.

Why UK businesses are investing in sustainable upgrades

Rising energy costs & carbon targets

Energy prices and regulatory expectations continue to push businesses to reduce operating costs and emissions. Investing in efficiency often delivers measurable savings and improves resilience to future price changes.

Customer and supply chain expectations

Customers, procurement teams and corporate buyers increasingly prefer suppliers with credible sustainability credentials. Upgrades can strengthen competitiveness and win new contracts.

Government incentives & regulation

Grants, tax allowances and local incentives can reduce project costs — and many lenders will consider blended funding (grants + loans) when structuring proposals. It’s worth exploring available support alongside commercial finance.

How Fast Business Loans helps you secure sustainability finance

We are a specialist introducer. We don’t lend or provide regulated financial advice — we match businesses with lenders and brokers who specialise in sustainability finance. Here’s how the process works:

1. Tell us about your project

Complete a short enquiry (less than 2 minutes) describing your business, the project, and the funding required.

2. We match you with trusted partners

We use your information to select lenders/brokers who understand your sector and project type.

3. Review tailored options

Brokers or lenders contact you with indicative terms and timescales. You compare offers and select the route that suits you.

Submitting an enquiry does not commit you to anything. You choose whether to proceed with an offer.

• No credit score impact at the enquiry stage.
• We only share your details with partners relevant to your request.
• Our service is free to businesses — lenders/brokers may charge fees for completed work (they will make any fees clear).

Costs, rates and repayment considerations

Typical interest rates & terms

Rates and terms vary by lender, product type and borrower profile. Expect a range depending on whether the loan is secured, unsecured or asset-backed. Lenders will provide firm quotes after review of your documents.

Secured vs unsecured

Secured loans can offer lower rates for larger projects since an asset or property reduces lender risk. Unsecured options suit smaller upgrades but may carry higher rates and shorter terms.

Combining grants, tax reliefs and finance

Many businesses combine grants or incentives with commercial finance to reduce net funding needs. Seek independent tax advice where necessary; our partners can help structure proposals but do not provide tax advice on behalf of Fast Business Loans.

Important: We introduce you to lenders and brokers who will quote directly; no rates or approvals are guaranteed by Fast Business Loans.

Common questions about sustainability loans

1. What projects qualify for sustainability finance?

Many lenders consider renewable energy, energy efficiency, EV infrastructure, waste reduction equipment and sustainable construction. Each lender has its own criteria — submit an enquiry so we can match your exact project.

2. Can newer businesses access green loans?

Yes — some lenders and brokers will consider younger companies if there is a clear business case or contracted revenue. They may require director guarantees or staged finance.

3. Do I need evidence of carbon savings?

Providing projected energy or carbon savings strengthens your application and may be required for certain green-labelled products. Supplier quotes or energy audits help.

4. How quickly can funds be released?

Timescales vary. Smaller unsecured loans can be arranged in days; larger secured projects may take several weeks. Brokers will advise realistic timelines once they review your documents.

5. Can loans be combined with grants or incentives?

Yes. Many businesses use grants, tax reliefs and loans together. Our partners can help structure blended packages but you should seek independent tax advice where needed.

6. Will enquiring affect my credit score?

No. Completing our enquiry does not affect your credit rating. Individual lenders or brokers may carry out checks later and will explain this before proceeding.

7. What if I was declined elsewhere?

Different lenders have different criteria. Our panel includes specialists who may consider applications declined by mainstream lenders. There’s no obligation to proceed after enquiring.
