Due diligence

In plain terms

Due diligence is the homework a lender or investor does before they part with money. Rather than taking your figures at face value, they check that the business is what it claims to be: that the numbers reconcile, the company is solvent, the directors are who they say they are, and there are no hidden liabilities lurking off the balance sheet.

For short-term business finance the process is usually proportionate and fast. A lender extending working capital to a UK limited company will verify the company's filings, recent bank activity and trading performance, but won't run the multi-month investigation you'd expect in an acquisition. The deeper the commitment, the deeper the dig.

Why it matters to your business

Due diligence cuts both ways. A lender uses it to price risk and decide how much to advance; you can use the same process to win faster, better-value funding. When your records are clean and your story is consistent, underwriting is quicker and the lender has fewer reasons to add caution into the rate or the limit.

It also protects you. A lender that does proper due diligence is one that understands your business and is less likely to advance more than you can comfortably service. That alignment matters — see responsible business lending. Poor preparation, by contrast, is one of the most common causes of delay and decline.

Typical checks include verified management accounts or filed accounts, bank statements, the company's balance sheet, director identity and credit history, and confirmation that the business is up to date with HMRC.

A worked example

A Manchester engineering firm applies for a £60,000 working-capital facility. Within 48 hours the lender pulls Companies House filings, runs an electronic ID check on the directors, reads 90 days of bank transactions through Open Banking, and reviews the firm's latest management accounts.

The figures reconcile, turnover is steady and there are no County Court Judgments. Because the records were ready and consistent, due diligence completes in two working days and the facility is offered without a personal guarantee. Had the bank feeds been missing or the accounts stale, the same review could have stretched to a fortnight of back-and-forth.

How to prepare

You can shorten due diligence dramatically by having the evidence ready before you apply:

• Keep filed accounts current and management accounts no more than a month old.
• Connect read-only bank data via Open Banking so the lender sees real cash flow.
• Resolve any CCJs, defaults or HMRC arrears, or be ready to explain them honestly.
• Make sure Companies House shows the correct directors, PSCs and registered address.

Honesty is the single biggest accelerator. A problem you disclose is a fact to be priced; a problem the lender discovers is a reason to walk away.
