How much can my business borrow? A practical guide for UK businesses

No responsible lender can quote a universal borrowing figure without understanding your business, the product and the purpose of the finance. The amount available may range from a relatively modest working-capital facility to a much larger asset-backed or property-backed arrangement.

In practice, the realistic amount is usually constrained by three things: the amount the business needs, the amount the lender is prepared to offer, and the amount the business can reasonably afford to repay. The lowest of these will often determine the practical borrowing limit.

How much can my business borrow? In short: how much a UK business can borrow depends on its turnover, profitability, cash flow, existing debts, trading history, credit profile, available security and the type and purpose of the finance. Each lender applies its own criteria, so the same business may receive different outcomes from different providers.

Consider two simplified examples. Business A turns over £1 million but operates on a very narrow margin, has several existing facilities and experiences frequent cash shortages. Business B turns over £600,000, produces consistent profit, maintains positive bank balances and has limited existing debt. Business B might appear more able to support repayments despite lower turnover. This is an illustration only — lenders assess the complete application, not turnover in isolation.

Affordability means whether the business can meet the proposed repayment while continuing to operate normally. Lenders may consider the expected repayment amount, repayment frequency, existing monthly commitments, normal operating expenses, seasonal or volatile revenue, and sensitivity to a fall in income or increase in costs.

They may use historical bank statements, filed accounts, management accounts and forecasts. A simple principle: after meeting the new repayment, the business should still have enough cash to operate and absorb reasonable changes in trading. Providers use different assessment methods. This guide does not describe a universal debt-service ratio.

The product type can change what amount is realistic. Asset-backed or invoice-backed structures assess different information from a general unsecured business loan.

Imagine an established UK engineering business with annual turnover of £750,000, consistent but modest profit, two years of filed accounts and existing vehicle finance repayments. The business seeks £80,000 for a new machine that is expected to increase production capacity. It will contribute a deposit. Trading is somewhat seasonal.

A lender may examine whether current and forecast cash flow supports the repayments, the existing vehicle finance, the value and useful life of the machine, the deposit, recent management information, customer concentration, seasonal pressure, and the directors' and company's credit profiles. Asset finance may be more appropriate than a general unsecured loan.

The lender might offer the full amount, a smaller amount, a different term, request additional security or decide the application does not meet its criteria. This example demonstrates the assessment process, not a likely or guaranteed outcome. Finance is subject to status and provider terms.

• Identify the exact amount required.
• Separate essential funding from "nice to have" spending.
• Review average monthly cash inflows.
• List normal operating costs.
• List all existing finance and debt repayments.
• Allow for tax, VAT and seasonal expenditure.
• Model a realistic proposed repayment.
• Stress-test the result against weaker trading or higher costs.
• Check that the business retains an adequate cash buffer.
• Discuss the figures with an accountant or professional adviser where appropriate.

Repayment schedules differ between products and providers. This exercise helps you form a view before applying — it is not a substitute for a lender's assessment.

• Keep company and accounting records up to date.
• Prepare recent business bank statements.
• Explain unusual transactions or temporary trading disruptions.
• Make the use of funds specific.
• Request an amount supported by a clear cost or opportunity.
• Prepare current management accounts where available.
• Build a realistic cash-flow forecast.
• Disclose existing borrowing accurately.
• Deal with avoidable filing or payment issues.
• Explain seasonality and customer concentration.
• Have quotations or invoices ready for asset purchases.
• Avoid making many poorly targeted applications in a short period.

For a fuller checklist, see Preparing for a business loan application. Our funding readiness guide outlines information commonly requested before you apply.

• Reduce or phase the requirement
• Increase the business's contribution
• Consider a different finance product
• Use asset-backed or invoice-backed funding where appropriate
• Review existing borrowing
• Provide additional supporting information
• Wait until more trading evidence is available
• Explore security where appropriate and understood
• Reconsider whether taking on the borrowing is currently sustainable

A smaller offer is not automatically a bad outcome if it keeps repayments manageable.

Finance is not suitable in every situation. Warning signs may include:

• Borrowing would only delay an underlying inability to meet obligations
• The business has no credible repayment source
• The proposed repayment would remove the operating cash buffer
• Funds are being used without a defined business purpose
• The business is repeatedly borrowing to meet existing debt repayments
• Directors do not understand the security or guarantee being requested
