What documents do you need to apply for a business loan?

Written by the Lendus editorial team · Last updated: April 2026

In short

The documents required for a business loan depend on the loan type and amount, but most applications need 2–3 years of business accounts, 3–6 months of bank statements, proof of identity and address for directors, and details of any existing borrowing. Larger or secured loans require additional items such as property valuations, management accounts, and a business plan. Open Banking connections now allow many lenders to access bank data directly, speeding up the process.

Business Loan Document Checklist by Loan Type

Unsecured Business Loan (£10,000–£150,000, fintech lender)

This is the fastest category — many decisions are made within hours.

  • Business bank statements — last 3–6 months (or Open Banking connection)
  • Proof of identity — passport or driving licence for all directors/owners
  • Proof of address — utility bill or bank statement, less than 3 months old
  • Companies House registration number (limited companies)
  • Basic details of the loan purpose

Many lenders in this category — iwoca, Funding Circle, Capital on Tap — can make a credit decision within 24 hours using bank statement data alone, without requiring accounts.


Unsecured Business Loan (£150,000–£500,000, mainstream lender)

  • 2–3 years of filed accounts (P&L and balance sheet)
  • Latest management accounts (if most recent accounts are 6+ months old)
  • 6 months of business bank statements
  • Proof of identity and address — all directors
  • Details of existing borrowing (loans, overdrafts, leases, CBILS/BBLS outstanding)
  • Loan purpose statement
  • Business plan (often required at this level)

Secured Business Loan / Commercial Mortgage

  • 3 years of business accounts (accountant-certified where possible)
  • 6–12 months of business bank statements
  • Management accounts (current year to date)
  • Details of the security property (address, tenure, current valuation if available)
  • Tenancy schedule (if investment property)
  • Proof of identity and address — all directors with 25%+ shareholding
  • Personal statement of assets and liabilities — all directors providing personal guarantees
  • Personal tax returns / SA302 forms (2–3 years)
  • Business plan or loan purpose document
  • Details of all existing debt obligations

Asset Finance

  • 1–2 years of accounts (or bank statements for smaller amounts)
  • Quote or invoice for the asset being financed
  • Proof of identity — primary director
  • Details of existing finance agreements
  • Personal guarantee consent (signed by all guarantors)

Invoice Finance

  • 6–12 months of accounts
  • Current aged debtor ledger
  • List of key customers (names, invoice values, payment terms)
  • 3 months of business bank statements
  • Proof of identity and address — directors

Why Consistent Documents Matter

A common reason for delays — or declined applications — is inconsistency between documents. If your accounts show a different business name than your bank statements, or if your filed accounts differ significantly from the management accounts you’ve provided, lenders will pause to investigate.

Before applying, check:

  • Business name is identical across all documents
  • Directors listed in accounts match those providing ID
  • Any discrepancies between filed accounts and management accounts are explainable (seasonal business, one-off exceptional items, etc.)
  • Bank statements show the correct business account, not a personal account

Open Banking: The Fastest Route to Approval

Open Banking has fundamentally changed small business lending. Lenders who have integrated Open Banking (the majority of major fintech lenders as of 2026) can:

  • Access 12–24 months of transaction history in seconds
  • Automatically categorise income and expenditure
  • Identify seasonal patterns, recurring payments, and cash flow trends
  • Make credit decisions without manual document review

For loans under £150,000, Open Banking significantly reduces the time from application to decision. Many borrowers complete the application in under 20 minutes and receive a decision the same day.

Tips for Faster Business Loan Approval

Keep your accounts current. Filed accounts that are 18 months old force lenders to request management accounts, which adds time. Where possible, file accounts promptly and keep management accounts updated quarterly.

Separate business and personal banking. Lenders expect business transactions in a business account. Mixed accounts — particularly for sole traders — slow underwriting because the lender must manually identify business income.

Know your credit file. Both personal (Experian, Equifax, TransUnion) and business (Creditsafe, Dun & Bradstreet) credit checks are carried out. Checking these before applying allows you to identify and explain any adverse entries in advance.

Have your loan purpose ready. A clear one-paragraph description of what the loan is for, how it will generate a return, and how it will be repaid is useful even when not formally required. Underwriters are people — a clear narrative makes their job easier.

Use a broker for larger or complex applications. For loans over £250,000 or where your business profile is non-standard (new business, adverse credit, complex structure), a commercial finance broker can identify the right lender from the start — avoiding multiple applications that each leave a mark on your credit file.

Frequently asked questions

Do I need 2 years of accounts to get a business loan?
Not always. Many fintech lenders — including iwoca, Funding Circle, and Tide — can make decisions based on 6–12 months of bank statements or Open Banking data, without requiring formal accounts. Larger loans (over £100,000) and loans from traditional lenders and banks typically require 2–3 years of certified or filed accounts. If you are a new business under 2 years old, focus on lenders who use bank statement-led underwriting.
What is Open Banking and how does it speed up business loan applications?
Open Banking allows you to securely share your business bank account data with a lender via a direct API connection. Rather than downloading and uploading bank statements manually, you connect your account in seconds and the lender can see your full transaction history, cash flow patterns, and income in real time. This allows many lenders to make same-day or next-day decisions without requesting formal accounts. The connection is read-only — lenders cannot initiate payments.
What accounts do lenders typically ask for?
Most lenders ask for your full statutory accounts — profit and loss account and balance sheet — for the last 2–3 financial years. For sole traders and partnerships, this means your self-assessment tax returns (SA302 forms). For limited companies, filed accounts at Companies House are usually acceptable. Where the most recent filed accounts are more than 12 months old, most lenders also request management accounts to show current trading.
Do I need a business plan to get a business loan?
Not for most standard term loans and lines of credit from fintech lenders. A business plan is typically required for larger loans (generally over £250,000), start-up lending (where there are no accounts), loans from enterprise finance guarantee (EFG) schemes, or where the loan purpose requires context — for example, an acquisition or expansion into a new market. Even where not formally required, a clear description of the loan purpose and repayment plan can help your application.
How long does the document collection process typically take?
For Open Banking-enabled lenders, the process can be completed in under 30 minutes and decisions made the same day. For traditional lenders requiring full accounts, the process typically takes 3–10 working days to gather documents and a further 2–4 weeks for underwriting. The most common delay is the borrower providing incomplete or inconsistent documents — ensuring your accounts, bank statements, and ID are consistent and current before applying significantly speeds up the process.
