A customer credit check means reviewing the credit risk of a company, their payment habits, and existing debts before you set their credit terms. It gives you a health score for that business, so you can see how likely they are to pay on time.
You should always run the check on every new customer before you agree terms, then revisit it periodically for any existing customers. A business that's paid reliably for years can still hit financial difficulty, so treat this as something you carry out regularly.
Here’s how to run a credit check on a customer:
Step 1: Start with a credit application form
Before you request any external checks, ask the customer to complete a credit application form. This will give you what you need and shows them you take credit decisions seriously.
Ask for:
- The full legal name of the business, plus any trading names
- Company registration number
- Legal status of the business. (This could be sole trader, partnership, limited liability partnership, or public limited company)
- Names of the business owners or directors
- Contact details for whoever handles payments and queries
- The amount of credit they're requesting
- Consent to approach a credit reference agency, their bank, and at least two trade references
Remember that the bigger the credit line, the deeper the check you should run. Start with the basics for a modest request and work through every step for a larger one.
Step 2: Gather the right information
The next step of the customer credit check process is collecting the right information about their creditworthiness. An audited financial statement is the gold standard data for understanding your customers' financial position. This is especially important in how to run a credit check on a new customer, but there’s a challenge: not all privately held customers may be willing to share their financial statements with you upon request.
Fortunately, there are several other sources of information:
Companies House and the Insolvency Service
Every UK limited company must file annual accounts and a confirmation statement with Companies House, both free to view. You won't get a credit score here, but you'll get a fast, no-cost check on whether a business is active, up to date with its filings, and who's running it.
You should treat a status marked "in administration" or "liquidation" as a red flag straight away, and a company that often files its accounts late needs a closer look, even if its status still shows as active.
If you're checking a sole trader rather than a limited company, the Individual Insolvency Register is the equivalent free source. This covers bankruptcies, IVAs and debt relief orders for individuals, but not limited companies, as they are covered by Companies House itself.
Credit bureaus
A business credit check through a credit bureau gets you a company credit report sold to qualified lenders, covering annual sales, invoice activity, credit limits and a business credit score, usually out of 100, with anything above 75 treated as strong.
Keep an eye out for County Court Judgments (CCJs). You can check the Register of Judgments, Orders and Fines directly for a small fee, and any record of legal action over unpaid debts is a strong warning sign, regardless of how the rest of the report reads.
Bear in mind that credit reports are based on information made available by the provider according to that moment in time. This means the information may be upwards of a year old and may not reflect real-time developments in the company's creditworthiness. You may have to combine credit reports with additional credit assessment tactics, such as risk data analysis that comes with a trade credit insurance policy.
Trade references
You can also ask your customer for trade references, which can include the customer’s bank, as well as businesses or suppliers that already extend trade credit to that customer. For example, you can ask how long the business or supplier has extended credit to the customer, how many times they were late to pay, etc.
However, be careful about bias when reviewing these references as the customer is likely to have provided information on companies they pay on time and omit companies that they don't. And be conscious that collecting this information can consume a great deal of time as you are dependent on receiving timely replies.
Chambers of commerce
Chambers of commerce and other local business organisations can also attest to the customer’s reputation in the industry and provide ‘soft knowledge’ about your customers’ values and involvement in the communities where they operate.
Trade credit insurers
Another source of information can be your trade credit insurer. Trade credit insurance offered by an international expert such as Allianz Trade includes customer credit check services as part of the policy. Our proprietary intelligence network analyses daily changes in over 80 million corporates’ solvency and attributes a health score to all companies via a risk grading. This customer health score helps you make accurate credit decisions.
So, you get a data-backed health score without piecing one together yourself. Our guide to building a network of creditworthy partners goes further into ongoing credit monitoring.
