Quick summary: What this page covers
If you’re applying for sustainability finance (for example solar PV, heat pumps, battery storage, EV chargers or energy-efficiency upgrades) lenders typically ask for a combination of:
- Company identity docs (Companies House printout, director details)
- Financials: filed company accounts (2–3 years), recent management accounts, and business bank statements (3–12 months)
- Supplier quotes and equipment specs with line-item costs
- Energy assessments, savings/payback calculations, and EPCs or MCS/SAP reports
- Planning, building control approvals, and any grant award letters
Having these ready speeds eligibility checks and formal underwriting. Ready to get a tailored response? Get Quote Now.
Why lenders care: how documents affect eligibility and speed
Lenders and brokers need to assess three things quickly: the business’s ability to repay, the viability of the sustainability project and any security offered. Clear, well-organised documents reduce back-and-forth and shorten approval times.

The primary documents you’ll almost always need
1. Business identity & ownership
- Companies House printout / certificate of incorporation (most recent)
- Memorandum & Articles or shareholder register (if requested)
- Director details, home addresses and NI/UTR where required for checks
- VAT registration certificate (if VAT applies)
Tip: supply PDFs of official documents and ensure company names and registration numbers match across all paperwork.
2. Financial history & strength
Lenders need to confirm trading performance and cashflow. Typical requests include:
- Filed statutory company accounts (last 2–3 years). Formats: PDF or SAO-certified copies.
- Latest management accounts (3–6 months) with Profit & Loss and Balance Sheet.
- Business bank statements — usually the latest 3–6 months; some lenders ask for 12 months. Include personal bank statements if directors give personal guarantees or there are director loans.
- Recent VAT returns, tax computations and evidence of any tax clearance arrangements.
- For newer businesses: cashflow forecasts, pro-forma accounts and CVs of directors to evidence experience.
File types accepted: PDF, XLS (for forecasts), or scanned JPGs for older paper statements — PDFs are preferred.
3. Project-specific paperwork
Evidence that the sustainability project will deliver value is central. Provide:
- Supplier quotes — detailed, dated quotes showing equipment, installation, labour, VAT and any contingencies. Lenders generally prefer 2–3 competitive quotes where possible.
- Equipment specifications — brochures, model numbers, warranty terms, expected lifetime and residual values for financed assets.
- Energy assessments & savings calculations — MCS certificates, SAP reports, or an energy consultant’s report showing projected savings and payback period.
- Planning / building control / grid connection — evidence of permissions or applications, especially for larger rooftop or ground-mounted systems.
- EPCs where relevant (e.g., building fabric upgrades) and any grant eligibility paperwork or award letters.
Supplier credibility matters: installers with MCS certification and third-party performance guarantees make underwriting smoother.

Additional documents some lenders will ask for
Depending on lender type and the security required, you may also be asked for:
- Title deeds and property details where property is offered as security
- Company charge documents, debentures or mortgage documentation
- Insurance evidence: public liability, employer’s liability, project insurance
- Supply or lease agreements (roof lease, O&M contracts, performance contracts)
- Aged debtor and creditor reports, recent supplier invoices
- Director ID & proof of address (passport, driving licence, recent utility bill)
- For asset finance: serial numbers, condition reports and residual value estimates
- Evidence of grant match-funding or third-party contributions
How documents differ by loan type
Not all finance products require the same evidence. Typical variations:
- Asset finance (lease / hire purchase) — focused on supplier quote, asset specs, trading history and short management accounts.
- Term loans / secured green loans — require full company accounts, comprehensive project plan, energy modelling and often property or debenture security.
- Invoice finance / working capital — ageing invoices, contract evidence and bank statements are central.
- Grants / blended finance — grant forms, quotes and evidence of match funding are required.
Specialist green lenders may accept shorter trading histories if energy performance evidence and robust supplier warranties are in place.
Practical tips to prepare documents faster
- Save all files as PDFs and use clear file names (e.g., CompanyAccounts_2023_UKBL.pdf).
- Gather bank statements early — request e-statements from your bank if needed.
- Ask suppliers for quotes that break out equipment, installation and VAT. Lenders dislike lump-sum, vague quotes.
- Use an accredited energy assessor or MCS installer to generate credible savings reports.
- Organise documents in a single folder or ZIP with a short index file listing contents.
- Respond quickly to follow-up queries — underwriting stalls when lenders wait for one missing document.
- Consider uploading documents to a secure portal only after an initial match — progressive profiling reduces friction at first contact.
Typical lender timelines and what to expect
Timescales vary by lender and complexity:
- Initial eligibility check: hours to 48 hours (with basic documents).
- Formal application & due diligence: 1–4 weeks (longer when security, planning or grid connections are involved).
- Drawdown and installation: often staged payments — deposit, delivery and commissioning stages are common.
Complete documentation and multiple supplier quotes usually shorten these windows significantly.
Common pitfalls and how to avoid them
- Vague supplier quotes — ensure line-item breakdowns.
- Out-of-date bank statements — lenders typically want the most recent statements.
- Unrealistic savings forecasts — back projections with a recognised energy model or assessor report.
- Mismatched company details — ensure Companies House name and registration number match all forms.
- Late responses to due diligence requests — delays often cause pricing changes or declined offers.

How many supplier quotes do I need?
Where possible, provide 2–3 detailed quotes. Lenders prefer quotes that break out equipment, installation, VAT and any maintenance or warranty costs.
Can I use expected savings to qualify?
Yes — lenders commonly consider projected energy savings, but they require credible energy assessments or MCS/SAP reports to accept those savings in underwriting.
Will applying affect our credit score?
Submitting an enquiry via UK Business Loans for a free eligibility check does not affect your credit score. Lenders may perform credit checks later during formal applications.
What if I’m a start-up — can I still apply?
Yes. Expect more emphasis on cashflow forecasts, founder experience and supplier contracts. Specialist lenders may consider strong project evidence and performance guarantees in place of long credit histories.

1. What documents do I need to apply for a sustainability loan?

3. Will submitting an eligibility enquiry via UK Business Loans affect our credit score?
No — the free eligibility check/enquiry does not affect your credit score; lenders may perform credit checks only if you proceed to a formal application.
4. Can start‑ups and new businesses get sustainability or other business loans?
Yes — specialist lenders and brokers often consider start‑ups if you provide strong cashflow forecasts, director CVs, supplier contracts and credible project evidence.
5. How long does the sustainability loan process usually take from eligibility check to drawdown?
Expect an initial eligibility response in hours to 48 hours, formal underwriting in 1–4 weeks (longer if security, planning or grid works are needed) and staged drawdowns for installation.

Asset finance focuses on supplier quotes, asset specs and shorter trading history, while secured green or term loans require full company accounts, detailed project plans and often property or debenture security.

Yes — lenders will consider projected savings but require credible energy modelling, MCS/SAP reports or an accredited assessor’s report to include those savings in underwriting.
9. Do I need planning permission, building control or grid connection evidence for larger renewable projects?
For larger rooftop or ground‑mounted systems lenders commonly require evidence of planning/building control approvals or grid connection applications before drawdown.
