Understanding your business credit score

What a business credit score actually measures

A business credit score is a number that summarises how likely your limited company is to pay its obligations on time. In the UK the main bureaux — Experian, Equifax and Creditsafe — each publish their own score, usually on a scale of 0 to 100, where higher is safer. It is a judgement about the company as a legal entity, built from public and shared data rather than your personal finances.

Unlike a consumer credit score, a company score is largely public. Anyone — a supplier weighing up credit terms, a landlord, a prospective customer or a lender — can buy a report. That visibility matters: a weak score quietly raises the price of doing business long before you ever apply for finance.

Who calculates it, and from what data

Each bureau builds its score from a blend of sources. The biggest inputs are usually:

• Companies House filings — accounts, confirmation statements, and whether they are filed on time.
• Trade payment data — how promptly you pay suppliers, fed in by other businesses.
• Public records — County Court Judgments (CCJs), defaults and insolvency markers.
• Financial ratios — gearing, liquidity and net worth drawn from your accounts.
• Company age and structure — a longer trading history reads as lower risk.

Because each bureau weights these differently, your scores will not match across providers. That is normal. Lenders know it too, which is why most underwrite on more than one source.

How lenders read the number

A score is a starting point, not a verdict. A commercial lender treats it as one signal among several: bank statements, turnover, the age of the business and the purpose of the borrowing all feed the decision. A mid-range score paired with strong, consistent cash flow can still secure a facility; a high score on a dormant-looking company may not.

What the score does change is pricing and friction. A stronger profile typically means a faster decision, a higher limit and a finer rate. A weaker one means more questions and, sometimes, security. Understanding the way interest is priced to risk helps you see why two companies are quoted very differently for the same amount.

The factors you can move quickly

Some inputs take years to mature, but several respond within weeks:

• File on time. Late accounts and confirmation statements are a direct, avoidable penalty.
• Clear any CCJs. An unsatisfied judgment is one of the heaviest single drags on a score; settling and marking it satisfied helps.
• Pay suppliers to terms. Trade data updates monthly, so consistent prompt payment shows up fast.
• Keep details current. Mismatched registered addresses or SIC codes can suppress a score or cause a thin file.

Checking your own profile

You are entitled to see what bureaux hold on your company, and you should — quarterly is a sensible rhythm. Each bureau offers a business report, and several provide an ongoing monitoring subscription that alerts you to changes such as a new CCJ or a director update. Checking your own company file does not harm the score, unlike a flurry of hard credit searches from applications.

If you spot an error — a payment recorded as late that was paid on time, or a judgment that has been settled — raise a dispute with the bureau directly and supply evidence. Corrections can take a few weeks to flow through, so fix problems well before you intend to apply for finance.
