How to credit check a company — and what the check won't tell you

There are two ways to credit check a UK company. You can search the official records yourself at little cost, although collecting and interpreting them takes time. Or you can use a credit-check provider, which consolidates those records with its own data and returns a score, a suggested credit amount, and, depending on the provider, the factors influencing them. Most credit teams use both: the records directly when they want to see the evidence, a provider when they need a decision quickly or have a ledger too large to check by hand.

This guide covers both routes, what the results mean, which warning signs deserve investigation, and what a credit check cannot establish.

What is a company credit check?

A company credit check combines public records with any proprietary payment, financial or behavioural data held by the provider, then turns that evidence into an assessment of risk.

Two things are worth understanding before you read one.

A score is an opinion produced by a model, not a fact about the company. The same company can carry different scores with different providers on the same day. A difference does not automatically mean one provider is wrong. They may hold different evidence, predict different outcomes or weight the same information differently. The useful question is what each score predicts and which evidence produced it.

Thin information is also a poor proxy for high risk. A company incorporated three months ago, or one that has only ever filed small-company accounts, gives a model very little to work with, and some providers will score it low as a result. That tells you the company is hard to assess, which is a real problem in its own right, and a different one from the company being in trouble. Where the entity has little history, the directors behind it often have plenty.

How to credit check a company in the UK

The two routes can be used together.

1. Check the underlying records yourself. Companies House, The Gazette, the judgment register and, for larger companies, published payment performance. Free apart from a small charge for judgment searches. You read the evidence and draw your own conclusion. Practical for a single new account, and slow across a ledger.

2. Use a company credit-check provider. A provider assembles many of the same public records, adds any payment, financial or behavioural data it holds, and applies its own model. It returns a score, a suggested credit amount and, depending on the provider, the factors behind them. This covers ground you cannot easily cover yourself, particularly payment behaviour reported by other suppliers. If you are choosing between providers, we have written a comparison of the main UK options.

Both routes answer the same question: how much confidence does the available evidence support, today.

What can you check for free?

Much of the baseline information in a company credit report is public, although payment experiences, financial-agreement data and scoring models may be proprietary. Four sources cover most of the public side.

Companies House. Free. Registered address, incorporation date, accounts, directors, people with significant control, registered charges and insolvency filings. Companies House shows whether statutory filings arrived on time and provides the underlying filing history, which is often more informative than any single document in it.

The Gazette. Free. The official public record of insolvency notices in the UK, including winding-up petitions and administration and liquidation appointments.

The Register of Judgments, Orders and Fines. Registry Trust maintains the statutory register for England and Wales on behalf of the Ministry of Justice, and provides access to the equivalent registers for Scotland, Northern Ireland, the Isle of Man, Jersey and the Republic of Ireland. Searchable at TrustOnline for £6 per search at the time of writing. You do not need the company's permission, the search leaves no footprint, and records remain on the register for six years from the date of judgment.

Payment practices reports. Free, and underused. Large UK companies and LLPs must report twice a year on their average time to pay, the proportion of invoices paid in 30 days or fewer, in 31 to 60 days and in 61 days or more, and the share not paid within agreed terms. Where your customer is large enough to report, this is the company's own statutory account of how it paid suppliers during the reporting period. Useful in construction and distribution, where the main contractor or the buying group sets the pace for everyone below it.

What does a company credit report show?

Contents vary by provider. Most reports include the following.

A credit score or risk band. It usually estimates the likelihood of a defined adverse outcome, such as insolvency, serious delinquency or default, over a stated period. Check what that provider's score actually predicts. Two providers can both call a company low risk while measuring different things over different horizons.

A suggested credit amount. Providers calculate and define this differently. It is generally a modelled recommendation for maximum exposure rather than an instruction to extend that amount. Unless you provide the relevant internal data, it cannot account for your margins, payment terms, security, existing exposure, risk appetite or portfolio concentration. Low risk is not a lending limit.

Payment performance. Usually expressed as average days beyond terms, sometimes with a trend. Its usefulness depends on how many suppliers contribute data about that company, which the report may not tell you.

Legal notices. Judgments and their satisfaction status. In England and Wales these are County Court Judgments. Scotland uses decrees, and Northern Ireland has its own register. The label differs; the meaning is broadly the same.

Directors and people with significant control. Names, appointment dates and, in most reports, other current and former appointments.

Group and connected companies. Parent, subsidiaries and sister companies, where the provider holds them. Worth reading rather than skimming: a subsidiary can hold a clean file while depending on a group under pressure.

Unfamiliar terminology is covered in our credit glossary.

What do common credit warning signs mean?

Most guides list warning signs and leave the reader to assume each one means trouble. In practice, the same signal carries different weight depending on the company, and what matters is what you do next.

Accounts filed late

The company filed after its deadline, or its filing behaviour has moved materially later than in previous years. Late filing can result from administrative problems rather than financial distress, so it should not be treated as evidence of insolvency by itself. What gives it weight is repetition and company: a pattern across several years, a move to smaller accounts than the company previously filed, or other signals shifting in the same period.

A judgment

A judgment shows that a creditor pursued a debt through court and obtained an order. It does not, by itself, establish that the company is insolvent. Check the amount, date, satisfaction status, frequency and whether other payment or filing signals are moving in the same direction. A single small judgment satisfied within a month reads very differently from three unsatisfied judgments across a year.

A director resignation

Start with the pattern rather than the event. A single departure can be a retirement, a restructure or a shareholder change, and tells you almost nothing. Look at how many changes have happened across what period, whether a senior finance executive or long-standing director appears to have left without an obvious replacement, whether the registered office changed at the same time, and whether the remaining directors hold appointments at companies under strain. Some of that comes from outside the registry, from the trade or from your own account manager.

Payment behaviour slowing

Reported days beyond terms have increased across consecutive periods, and the report will rarely tell you why. A buyer with greater bargaining power may be running a deliberate working-capital policy, which presents a margin, terms and bargaining-power problem. A customer paying later because of cash pressure may present a potential loss problem. The payment signal alone does not tell you which one you are seeing. Look at whether the slowdown is general or specific to certain suppliers, whether the company publishes payment practices data, and what your own sales ledger shows about order size and frequency.

A newly registered charge

A lender has taken security over company assets and registered it at Companies House. Most trading companies with borrowings carry charges, so this is context rather than a warning on its own. A charge does not necessarily mean the company has drawn the full facility it secures. Check who holds it, whether it is fixed or floating, what it covers, and how it would rank against your position if the company failed.

A signal tells you something changed. It does not tell you what happens next. It tells you to look.

How should you use the results?

A credit report is evidence for a commercial decision, and the decision is yours. Use the report in this order:

• Confirm the correct legal entity. Match the company number, not the trading name. Groups routinely run several similarly named companies, and the one placing the order is not always the one you assessed.
• Understand what the score predicts, and over what period.
• Read the reasons behind the score rather than the score alone. The reasons tell you whether it is driven by something structural or something recent.
• Assess the suggested exposure against your own circumstances: margin, terms, security, what you are already owed, and what losing this customer would cost you commercially.
• Examine the payment, legal, ownership and filing signals, and whether they point the same way.
• Decide the terms, limit, security and any approval conditions.
• Record what would cause the decision to be reviewed.

The outcome should be a specific commercial position, not a verdict on the company. In practice that means one of: approve on normal terms; approve with a lower initial limit and room to grow; ask for a deposit, guarantee or other security; shorten payment terms; request more information such as management accounts or a trade reference; escalate for manual review; or decline and trade on payment in advance.

Declining is only one of those options, and it is often the wrong one. A customer you cannot approve for £50,000 on 60-day terms may be perfectly sound at £5,000 on 30 days.

Four things a company credit check cannot tell you

A credit report describes what can be observed about a company. There are four important limitations.

Whether the registered people are the people you are actually dealing with. A report may show directors, PSCs and beneficial owners. That does not necessarily prove that the applicant, buyer or person communicating with you is genuinely connected to them. Identity verification at Companies House is also still working through a transition, so a filing currently confirms registration rather than settling the question. Companies House can verify a director; it cannot vouch for the company.

The company's full dependencies. A standard report may not show the company's customer and supplier concentrations. Some providers add network or concentration data, but no external file is guaranteed to reveal every commercially important relationship. A manufacturer can hold a clean file and take most of its income from one customer, and the effect of that customer failing reaches you through a company whose own record looked sound.

Your own position. The report assesses the company. It knows nothing about your margin, your terms, what you are already owed, what security you hold, or how much of your ledger sits with customers in the same sector and the same region.

What the company would say about it. A file cannot explain a late filing, a disputed invoice or a judgment the company is contesting. The business can, and asking is often quicker than inferring. When the evidence is incomplete, can the process obtain an explanation and supporting documents from the business itself?

How to credit check a sole trader or partnership

A sole trader is not a separate legal company, so there is no Companies House entity or statutory company filing history to check. Some commercial providers offer reports on unincorporated businesses, but the available information and the legal basis for using personal data differ from a limited-company check. The same is broadly true of an ordinary partnership.

You can take up trade references, confirm VAT details where applicable, search the appropriate judgment register and request financial evidence with the trader's knowledge and consent.

A personal credit search is a different matter again. It requires an appropriate lawful basis under UK data protection law and will normally require the individual's knowledge or permission. This is not something to run quietly on the back of a trade application. The ICO's guidance on lawful basis is the place to start if you are unsure.

Grand provides commercial credit information about incorporated UK businesses. It does not assess sole traders or individuals, and nothing from Grand should be used for consumer or sole-trader credit decisions.

What happens after the credit check?

A company credit check supports the decision you make today. If you continue trading on credit, decide what would cause you to review that decision: a new judgment, a late filing, an ownership change, or a deterioration in how the customer pays you. Monitoring can alert you to those changes, but it does not replace the original assessment.

Write those triggers down at the point of approval, and name who acts on them. Defining them later, with an invoice outstanding and a sales team waiting, is considerably harder.

The amount of exposure that makes sense today may not be the amount that makes sense six months later.

A credit check should lead to a commercial decision: whether to trade, on what terms, with what limit and based on which evidence. Record that reasoning while it is current. If the evidence changes later, review the decision rather than assuming the original answer still holds.
