How long do green business finance approvals take? (Solar PV, EV chargers, heat pumps)

Summary: Typical approval timelines for green business finance vary by product and project size. Small asset-finance deals (single-site EV chargers, small heat pumps, rooftop solar) commonly move from enquiry to funds in 1–2 weeks. Medium projects usually take 2–6 weeks. Large or complex commercial installations can take 6–12+ weeks because of technical surveys, legal charges and third‑party approvals.

Quick answer (TL;DR)

Why timing varies — key factors

No two green projects are identical, and that directly affects how long a lender takes to approve finance. Below are the main drivers of timeline variation.

Loan / finance product

Asset finance, hire purchase or invoice finance can be fast (often days to a couple of weeks) because they rely on the asset or invoice as security. Unsecured business loans, commercial property finance or development finance require more checks and therefore take longer.

Project size & scope

Small installs (one EV point or a single heat pump) require minimal technical due diligence. Commercial-scale solar, battery storage or multi-site EV rollouts need energy modelling, performance estimates and sometimes bespoke credit terms.

Security & credit

Secured loans that take a legal charge against property add solicitor and land registry steps. The borrower’s business credit profile and director history also influence underwriting time.

Documentation required

Lenders commonly ask for installer quotes, MCS/OZEV certificates (for solar/EV), management accounts, bank statements, and VAT status. The more complete these are at submission, the faster the decision.

Grants & third-party approvals

If a project relies on a grant or a subsidy (for example, certain EV or renewable incentives), administrative steps for grant confirmation can extend timelines.

Technical surveys & site consent

Surveys — structural, electrical or site access — and landlord or local authority consents can add days or weeks.

Market & seasonal factors

Lender capacity and installer availability (peak demand seasons) can cause bottlenecks independent of the lender’s underwriting speed.

Pro tip: providing two or three installer quotes, energy technical specs and recent accounts up-front will materially speed most applications.

Typical timelines by product & project type

The ranges below are realistic expectations used by lenders and brokers. Use them to plan procurement and installation schedules.

Small-scale installations & asset finance (single-site EV chargers, small heat pumps, single rooftop solar)

• Initial response: same day to 72 hours.
• Conditional approval / soft offer: 3–10 working days.
• Full approval & drawdown / finance agreement: 1–2 weeks (funding often tied to installer invoice).
• Why faster: asset-backed finance and standard documentation.

Medium projects (multiple EV points, commercial heat pumps, mid-sized solar arrays)

• Initial response: 24–48 hours.
• Underwriting & conditional approval: 5–15 working days.
• Surveys, grant confirmation & drawdown: add 2–4 weeks; total 2–6 weeks typical.
• Notes: technical due diligence and ROI/savings evidence are often requested.

Large-scale / complex projects (battery storage + solar, multi-site rollouts, major commercial installations)

• Initial response: 48–72 hours.
• Formal underwriting: 2–6+ weeks.
• Legal charges, surveys, third‑party consents: 4–12 weeks or longer; final funding often 6–12+ weeks.
• Why longer: bespoke lending terms, legal security and specialist technical surveys.

Checklist to speed things up: installer quotes, MCS/OEM certificates, 12–24 months accounts (or recent management accounts), bank statements, VAT registration and identification for directors.

How UK Business Loans speeds the process

We match your enquiry to lenders and brokers who specialise in sustainability projects — saving you the time of contacting multiple providers. Our typical process:

1. Complete a short enquiry with project type and estimated value.
2. We match you to suitable lenders/brokers with relevant experience.
3. A matched partner contacts you to run a free eligibility check and request documents.
4. Conditional offers, surveys and completion are coordinated to speed drawdown.

Most matches lead to a first contact within hours. Because we introduce you to partners experienced in green projects, conditional approvals tend to be faster than approaching a generalist lender.

What you can do to reduce approval time

Preparing documents before you submit an enquiry is one of the easiest ways to shorten approval timelines. Use this checklist:

• 2–3 installer quotes with equipment specs and installation timelines.
• MCS, OZEV or manufacturer accreditation details for equipment.
• 12–24 months business accounts or recent management accounts.
• Recent bank statements (typically 3 months) and VAT registration if applicable.
• Installer contract or purchase order and proof of site ownership/landlord consent where needed.
• Brief project summary showing estimated energy savings and payback for medium/large projects.

Ask the lender or broker about soft checks — many can give a conditional decision without a hard credit search, meaning you can explore options without immediate impact on credit records.

Common delays & how to anticipate them

• Missing paperwork: request a lender checklist early and upload documents promptly.
• Landlord or planning consent: obtain consent as early as possible if installation affects building fabric.
• Installer lead times: shortages or busy seasons can delay installation dates; coordinate finance and install schedules.
• Grant administration: grant applications or confirmation can add time; discuss grant assumptions with your broker so conditional offers factor them in.

Outcome: Matched same day; conditional offer in 48 hours; funds released to installer in 10 days. What sped it up: clear installer invoice, MCS details and up-to-date bank statements.

Example B — Industrial unit: 100kW solar + battery (approx. £180,000)

Outcome: Match and initial contact within 48 hours; lender requested technical survey and conveyancing for legal charge; final funding in 9 weeks. What delayed it: required site structural survey and landlord consent; what helped: detailed energy model and multiple installer quotes.

Frequently asked questions

How quickly will I be contacted after submitting the form?

Typically a matched lender or broker will contact you within a few hours during business hours. Response times depend on lender availability and how complete your enquiry is.

What’s the difference between a conditional approval and full approval?

A conditional (soft) approval confirms a lender is willing to proceed subject to documents, surveys or consent. Full approval follows completion of those steps and, where applicable, legal documentation.

Do green grants delay approval?

Grants can add administrative steps. Many lenders issue conditional offers that assume grant funding and then update timing once grant approval is confirmed — talk to your matched broker about this at the eligibility stage.

Can you help if my business credit is imperfect?

Yes — we work with brokers and lenders who specialise in a range of credit profiles. A free eligibility check will identify suitable partners and likely timelines based on your circumstances.

Will applying through UK Business Loans affect my credit score?

Submitting an enquiry does not affect your credit score. Lenders may perform credit checks later if you proceed to a formal application; your matched partner will explain when and how checks will be made.

How soon can an installer start once funding is approved?

Installer start dates depend on their schedule and lead times for equipment. Smaller installs can often be scheduled within 1–2 weeks of confirmed funding; large projects usually have longer lead times.
