Do you help with finance for renewables like solar, biomass, slurry systems, and heat pumps?

Yes — we help UK businesses find funding partners for renewables projects

Yes. Best Business Loans helps established UK businesses connect with lenders and specialist brokers for renewable and low‑carbon projects, including solar PV, biomass, slurry-to-energy systems (anaerobic digestion), and heat pumps. We don’t lend directly; we introduce you to suitable finance providers and help you compare your options.

Whether you’re aiming to cut energy bills, generate new revenue, or meet sustainability targets, our AI‑driven matching helps identify funding routes that fit your project size, sector, and cash flow. We support companies across agriculture, manufacturing, logistics, hospitality, healthcare, professional services, and more.

Submit a Quick Quote to check eligibility with no obligation. We aim to introduce you only to providers genuinely active in your sector and comfortable with renewable asset types.

What we do — in four simple steps

1. Tell us about your project. Share basic details about your business, the technology (e.g., solar, biomass, heat pump), budget, and timelines.
2. AI-driven matching. Our system analyses your profile against finance providers who fund similar renewable assets and sectors.
3. We connect you. You’ll be introduced to lenders or brokers who may be able to help, saving you time contacting multiple firms yourself.
4. You stay in control. Review indicative terms, ask questions, and decide what’s right for your business and cash flow.

It’s fast to enquire, and there’s no obligation to proceed. We’re transparent that we can’t always secure the absolute cheapest rate, but we aim to help you find relevant funding partners.

Fair, clear, and not misleading

We operate as an independent introducer. We don’t give regulated financial advice, and we don’t offer loans directly.

Any finance is subject to provider approval, status, affordability checks, and terms. Costs, eligibility, and timing vary by project, sector, and credit profile.

What renewable and low‑carbon projects can we help you finance?

We support introductions for a wide range of commercial sustainability projects. The most common are listed below, along with typical finance approaches lenders and brokers may use.

Where helpful, combined energy efficiency measures (LED, insulation, controls) can be packaged with generation or storage for a rounded business case. Funders often value integrated savings.

If you’re unsure which route is appropriate, submit a Quick Quote and we’ll help you navigate your options.

Solar PV and solar thermal

Commercial rooftop or ground‑mount solar PV is frequently funded via asset finance (hire purchase or finance lease), operating leases, or power purchase agreements (PPAs). PPAs can suit firms seeking low or no upfront capital.

Solar thermal is less common in non‑process industries but may apply to hotels, leisure, and food production. Funders typically prioritise proven equipment, established installers, and realistic yield assumptions.

Battery storage may be bundled with PV to improve self‑consumption and peak shaving. Some lenders favour projects with smart monitoring and performance guarantees.

Biomass boilers and CHP

Biomass heating and combined heat and power (CHP) arrangements are often financed via hire purchase, leases, or performance‑linked service contracts. Feedstock certainty is critical to underwriting.

Lenders may want evidence of supply agreements, emissions compliance, and maintenance plans. Where heat off‑take is contracted, it can strengthen the case.

State‑of‑the‑art emissions controls and reputable OEMs are helpful. Expect technical due diligence on design, sizing, and integration.

Slurry systems and anaerobic digestion (AD)

For agricultural and food waste operators, AD and slurry‑to‑energy projects can be funded through asset finance or project‑style structures, depending on scale and gas‑to‑grid or electricity export arrangements. Digestate handling and storage are key considerations.

Funders assess feedstock volumes, long‑term supply consistency, and off‑take agreements. Experienced EPC and O&M partners are often preferred.

If you’re a farm or agri‑business exploring AD or slurry systems, see our guidance on farming loans and rural energy finance for routes suited to agricultural operations.

Heat pumps (air, ground, and water source)

Heat pumps for commercial buildings, process heat, and district systems are commonly financed via leases, hire purchase, or heat‑as‑a‑service models. Careful design to building load profiles is essential.

Funders may look for MCS‑certified installers for smaller systems and robust design credentials for larger installations. A measured approach to COP and seasonal performance factors matters.

For retrofit projects, lenders may ask to see heating bills and building fabric assessments to validate savings claims and running cost projections.

Battery storage, EV charging, and efficiency bundles

Commercial battery systems, EV charging infrastructure, and smart controls are increasingly fundable, particularly when tied to clear use cases like peak shaving or fleet electrification. Data‑led ROI strengthens applications.

Many businesses also pair “quick win” measures (LED lighting, BMS upgrades) with generation to deliver blended paybacks. This can improve affordability and lender comfort.

Where grid constraints exist, funders may want evidence of DNO engagement and realistic timelines for connection or reinforcement.

Typical finance structures we can help you explore

• Asset finance: Hire purchase, finance lease, or operating lease for equipment and plant.
• Unsecured business loans: For smaller capex or project soft costs; subject to status and affordability.
• VAT and short‑term bridge finance: To cover staged payments and reclaim timing.
• Refinance: Release equity from existing assets to fund new sustainability investments.
• Project‑style structures and PPAs: Suitable for larger on‑site energy generation with off‑take contracts.
• Grant co‑funding: Where available; you remain responsible for eligibility and compliance.

Eligibility, documents, and timelines

Lender criteria vary by provider and technology, but there are common themes. Being prepared can improve speed and likelihood of success.

We typically help limited companies and established organisations, not start‑ups or sole traders. We also don’t handle property finance or commercial mortgages.

Below is a general overview to help you prepare a strong enquiry.

Who we can usually help

• Established UK companies with at least 12 months’ trading and filed accounts.
• Businesses with clear use cases: self‑consumption, process heat, export, or fleet charging.
• Operators in asset‑rich sectors such as agriculture, manufacturing, logistics, hospitality, healthcare, and professional services.

What lenders typically look for

• Credit profile, affordability, and existing borrowing commitments.
• Project scope, capex breakdown, and vendor qualifications.
• Reasonable payback assumptions, supported by energy bills or metered data.
• Planning, grid, or environmental permissions where applicable.
• Maintenance plans, warranties, and performance guarantees.

Documents to prepare

• Latest filed accounts and recent management information (P&L, balance sheet).
• Bank statements and aged debtor/creditor summaries where requested.
• Project proposal, quotes, technical specifications, and installer credentials.
• Evidence of energy usage, tariffs, and, if relevant, proposed off‑take contracts.
• Any planning or grid correspondence and timeline notes.

How long does it take?

Smaller asset finance decisions can be relatively quick once documents are in order. Larger or complex schemes may require technical due diligence and take longer.

Lead times also depend on installer schedules, grid permissions, and equipment delivery. Building a realistic timeline into your plan can help all parties.

Our role is to speed up introductions and reduce dead ends by matching you to active, relevant funders.

Costs, rates, and terms — what to expect

Pricing varies with credit profile, asset type, advance size, deposit, term, and residual values. As a rule, proven technologies, reputable suppliers, and strong financials tend to achieve better terms.

We avoid generic “from X%” claims because they can mislead. Instead, we encourage a Quick Quote so you can review indicative options tailored to your business.

Always consider total cost of finance alongside whole‑life asset costs, O&M, energy price assumptions, and downtime risks.

Benefits and risks — a balanced view for decision‑makers

Finance can accelerate decarbonisation and cost control, but decisions should be commercial, not just aspirational. Below is a balanced summary to support internal sign‑off.

Engage stakeholders early — finance, operations, estates, and sustainability — and agree success metrics. This helps keep projects on track and funder‑ready.

Where helpful, request performance‑linked guarantees or service agreements from suppliers to underpin outcomes.

Commercial benefits of financing renewables

• Reduce energy cost volatility through self‑generation and consumption.
• Potential new revenue streams from export or heat off‑take agreements.
• Improve ESG credentials and support tender requirements or client mandates.
• Match payments to savings with leases or PPAs to smooth cash flow.
• Preserve working capital by spreading capex over the asset life.

Key risks and considerations

• Performance risk if systems under‑deliver versus projections.
• Counterparty risk across installers, O&M providers, and off‑takers.
• Regulatory and tariff changes affecting export or usage assumptions.
• Operational impacts during installation or maintenance downtime.
• Insurance, warranties, and end‑of‑life responsibilities.

Procurement and supplier due diligence

• Shortlist accredited, experienced installers with relevant case studies.
• Request transparent design models, yield reports, and stress tests.
• Validate warranties, O&M terms, and response times in writing.

Tax, grants, and incentives — speak to your adviser

Tax rules change, and eligibility depends on your circumstances. Discuss with your accountant to confirm any capital allowances or reliefs that may apply.

For example, the UK’s “full expensing” regime for qualifying main‑rate plant and machinery can provide 100% first‑year relief for companies, but conditions apply. See guidance on GOV.UK for current rules and updates.

Grants and local schemes vary by region and technology. You remain responsible for checking eligibility, interactions with finance, and compliance.

Renewables finance FAQs

Do you finance start‑ups or sole traders?

No. We typically support established UK companies and organisations. We don’t currently handle start‑ups, sole traders, franchises, or property finance.

Can I fund multiple technologies in one package?

Often yes. Many funders will consider blended projects, such as PV plus battery and LED upgrades. The case should show combined savings and realistic phasing.

What if planning or grid approval is pending?

It’s still worth enquiring. Providers may issue terms subject to approvals. Funding can complete once conditions are satisfied.

Do you offer PPAs for zero‑capex solar?

We don’t offer PPAs directly, but we can introduce you to partners that structure PPAs. Suitability depends on site usage, roof condition, and term length.

How accurate do my savings projections need to be?

Projections should be evidence‑based and conservative. Use historical consumption data, tariff assumptions, and supplier modelling to support the case.

Is there support for agricultural slurry and AD projects?

Yes, subject to provider appetite and project strength. Feedstock assurance, EPC/O&M credentials, and off‑take visibility are central to lender comfort.
