A B2B credit check tells you whether a new client is likely to pay before you extend credit. A proper check covers Companies House filings, registered charges, County Court Judgments, insolvency notices and how the business pays its other suppliers. It takes minutes, and it is far cheaper than months of chasing. The Insolvency Service reported that one in 200 companies in England and Wales entered insolvency in the 12 months to August 2026, so skipping the check means lending to a stranger for free, with nothing behind it.
What is a B2B credit check?
A B2B credit check is a review of a business customer’s financial health and payment record before you agree credit terms. It combines public records with credit reference data to estimate how likely the customer is to pay on time. The result should shape your credit limit and payment terms, not just give you a yes or no.
We tell clients that skipping credit checks makes you an interest-free lender, which is a bank’s job rather than yours. When we take on a recovery, we start by assessing the debtor’s ability to pay through a credit check, because it shapes how the case is handled.
Why the risk is real in 2026
Company failures remain common. The Insolvency Service recorded 1,946 company insolvencies in England and Wales in August 2026, and its figures show construction with the most insolvencies over the year, at 3,866. Administrations were 44% higher than in July 2026 and 60% higher than in August 2025, with the data also noting more than 250 connected real estate companies entering administration between March and August 2026.
An insolvent customer rarely announces it. Our guides to financial distress rising across UK businesses and supply chain protection during administrations explain what unsecured suppliers face once a customer fails.
What a good credit check covers
| Check | What it tells you | Red flag |
|---|---|---|
| Company status and age | Whether the company is active and how long it has traded | Strike-off notice, or a very new company placing a large order |
| Filing history and accounts | Whether it files on time and whether accounts suggest stress | Overdue accounts or confirmation statements |
| Registered charges | Which lenders have security ahead of you | A rising number of recent charges |
| CCJs and insolvency notices | Payment behaviour and formal proceedings | Recent judgments, insolvency notices or a winding-up petition |
| Directors | Links to other companies | A pattern of failed businesses |
| Payment behaviour | How it pays other suppliers | Consistently slow payment |
Free checks and paid reports
Start with the free tools. Companies House makes its public company data available free, including filing history, charges and insolvency information, and you can follow a company to get email alerts when it files. The Gazette publishes formal insolvency notices. Our guide to Companies House checks for credit control shows what to look for.
Free records show what a company has filed, not how it behaves. Paid reports add payment performance, judgment data and suggested credit limits, which is why our credit checking service covers both UK and international companies. For sole traders and partnerships, use a reputable provider and make sure the check is proportionate, because personal data rules apply.
Turn the result into terms
A credit check is only useful if you act on it. A strong result may justify your standard terms. A weaker one may mean a lower credit limit, shorter terms, a deposit or stage payments. For higher exposure, consider security beyond personal guarantees and a properly drafted retention of title clause if you supply goods.
Build the check into onboarding. Our guide to KYC, contracts and credit limits sets out a practical process, and our piece on using technology to prevent late payment covers automation. The point is that a check is routinely skipped when a new client looks promising, which is exactly when it matters most.
Do not stop at onboarding
A clean check on day one says nothing about month six. Re-check customers periodically, follow key accounts on Companies House and keep aged debtors reporting current, so slow payment shows early. Track credit control KPIs to see whether your collection period is lengthening.
Our wider advice on B2B debt collection tips follows the same order. Check first, set sensible terms, chase early and escalate before an invoice ages.
Sectors and customers that need extra care
Construction suppliers and subcontractors face long payment chains and the highest insolvency numbers, so our construction debt collection team often sees the cost of a skipped check. Overseas customers are harder to assess and harder to pursue, so check them before you ship, and use our international debt collection service if an account stalls.
If a customer has already gone quiet
Do not wait. Our guide on when to escalate an invoice explains the timing, and recovering debt from insolvent customers covers what to do if formal insolvency begins. If chasing is falling behind, outsourced credit control keeps accounts moving.
Frequently asked questions
Are Companies House checks enough on their own?
They are a good start but not enough. Companies House shows filings, charges, company status and insolvency information, but not how the company pays other suppliers. A credit report adds payment behaviour, judgment data and suggested limits.
How often should I re-check a customer?
Check at onboarding, before you raise a credit limit and at regular intervals, such as annually. Check immediately if payment slows, the customer asks for longer terms, accounts become overdue or a new charge or insolvency notice appears.
Can I run a credit check on a sole trader?
Yes, in the right circumstances, but personal data rules apply. Use a reputable provider, keep to the purpose of assessing credit risk and avoid collecting more information than you need.
What should I do if a check shows a CCJ?
Treat it as a warning, not an automatic refusal. Consider a lower limit, shorter terms, payment upfront, a deposit or security. If the exposure is too high, declining the work may be safer than becoming another unpaid creditor.
Check first, chase less
A credit check cannot guarantee payment, but it takes away the biggest avoidable risk, which is trading blind. If you have overdue invoices from a customer you did not check, speak to our team for a free, no-obligation conversation about recovering them.
