What UK small businesses get wrong about credit checks on new clients

By InvoiceReminder Editorial Team · Published 5th August 2026

Failing to run a basic credit check on new business-to-business (B2B) clients is one of the most common and costly mistakes a UK small business can make. Too many freelancers and SMEs, eager to win new work, onboard clients based on a good conversation and a "gut feeling", only to find themselves with a hefty unpaid invoice months later. This article explains why skipping this simple, inexpensive step is a false economy and provides a practical guide to checking the financial health of your next client before you start the work.

The "Good Vibe" Fallacy: Why Gut Feel Isn't a Credit Control Strategy

When you're running a small business, building relationships is key. You meet a potential new client, they're enthusiastic about your proposal, and you have a great rapport. It feels rude or overly formal to then go and investigate their financial background. This is a trap.

Here are the common thoughts that lead to bad debt:

"They seem really nice and professional." A friendly contact person is not the company's accounts payable department. The person hiring you often has no control or visibility over when invoices actually get paid.
"They're a big, well-known company." Big names can be some of the worst late payers, often using their size to dictate long payment terms and stretch them even further. A large company can also be in serious financial trouble without it being public knowledge.
"I don't want to seem untrusting." A credit check is not a personal slight; it's a standard, professional, and prudent business process. Any serious business will be undergoing these checks from their own suppliers and will not be offended. If a potential client is offended, that itself is a major red flag.

The reality is that your "gut feel" cannot see a County Court Judgement (CCJ), it can't spot overdue company accounts, and it can't tell you that the client has a history of paying other suppliers 60 days late. Data, not feelings, should inform your decision to offer credit (which is what any invoice with payment terms is).

What a UK Business Credit Check Actually Tells You

A business credit report is not some mythical, complex document. It’s a straightforward summary of a company's financial health and payment behaviour, compiled from public records and data from other businesses. It gives you objective answers to the most important question: "Is this client likely to pay me on time?"

Here’s what you can expect to find.

Credit Score and Risk Rating

Most credit reference agencies will distil all the complex data into a simple score (e.g., 1-100) and a risk band (e.g., Low, Moderate, High, Severe). This is the headline figure. A high score suggests a healthy business that pays its bills, while a low score is a clear warning sign. The report will often include a recommended credit limit – the maximum amount the agency suggests you should have outstanding with that client at any one time.

Payment History (Trade Data)

This is arguably the most valuable part of a report. Credit agencies collect data from thousands of businesses on how quickly their customers pay them. This is often displayed as 'Days Beyond Terms' (DBT).

If a company's average DBT is 21 days, it means that on average, they pay invoices 21 days after the due date. If you offer 30-day terms, you can expect to be paid in around 51 days. This information is gold; it helps you forecast your cash flow realistically and decide if you can afford to work with that client.

Financial Health

The report will include key information from the accounts filed at Companies House. This can include:

Turnover
Profit & Loss
Balance sheet assets and liabilities
Cash at bank

While these figures can be up to 18-20 months out of date, they still provide a valuable snapshot of the company's scale and historical profitability. A history of losses or negative net assets is a cause for concern.

Adverse Information

This is the section detailing any serious trouble. It includes:

County Court Judgements (CCJs): This means another supplier has already had to take them to court for non-payment and won. It is one of the biggest red flags you can see.
Winding-up Petitions: A formal notice that a creditor is trying to force the company into compulsory liquidation to recover a debt.
Insolvency or Administration Notices: Details of any ongoing or past insolvency proceedings.

Seeing any of these on a report means you should only proceed on a 100% upfront payment basis, if at all.

Common Myths and Misconceptions About Credit Checks

Many small business owners avoid credit checks because of a few persistent myths. Let's debunk them.

Myth 1: "It's too expensive."

A single detailed business credit report typically costs between £10 and £30. Now, compare that to the cost of a single £1,500 bad debt. The time you waste chasing, the stress it causes, and the potential final loss of the entire amount makes the small upfront cost of a check a phenomenal investment. Basic checks using public data are also completely free.

Myth 2: "It's only for big corporations."

This is backwards. A large corporation can absorb a £10,000 bad debt. For a freelancer or a small business, that same amount could be the difference between survival and closure. The smaller your business, the more critical it is to protect your cash flow by vetting every new client.

Myth 3: "It's pointless for sole traders or partnerships."

It's true that non-limited businesses don't have the same public filing requirements as limited companies. However, you can (and should) still perform checks. You can run a consumer credit check on the individual (with their permission) or use a service like Trust Online to check for CCJs against their name and trading address. You can also ask for trade references from their other suppliers, which can be just as insightful.

Myth 4: "A good report means I'm guaranteed to get paid."

A credit check is a snapshot in time. It's a powerful risk assessment tool, not a crystal ball. A company with a great report today could lose a major contract tomorrow and face cash flow problems. That’s why a credit check is the first step in a robust credit control process, which also includes clear contract terms, prompt invoicing, and consistent chasing of overdue payments.

A Practical Guide: How to Credit Check a UK Business Client

You don't need to be an accountant to perform a powerful and effective credit check. Follow this three-step process.

Step 1: Start with the Free Checks

Before you spend any money, use the excellent free resources available to every UK business.

Companies House: The government's register of companies is your first stop. Search for the company name and look at the "Filing history" tab. Are their annual accounts or confirmation statement overdue? This is a classic sign of a disorganised or struggling business. Look at the "People" tab to see who the directors are.
The Gazette: This is the UK's official public record. Search the company name for any insolvency notices or winding-up petitions. A notice here is a serious warning.

These two free checks take less than five minutes and can immediately flag high-risk clients.

Step 2: Use a Commercial Credit Reference Agency

For a deeper dive, especially for a large project, use a paid-for service. The main providers in the UK include Experian, Equifax, and Creditsafe. These services consolidate all the data—Companies House info, CCJs, payment data, etc.—into one easy-to-read report.

You can usually buy a single report or sign up for a subscription which often includes monitoring, alerting you if one of your client's credit ratings changes.

The table below shows what you get from a paid report versus relying on free sources alone.

Feature	Free Companies House Check	Paid Credit Report (from a CRA)
Cost	Free	Approx. £10 - £30 per report (or subscription)
Basic Company Info	Yes (Name, Number, Address, Directors)	Yes (and often verified)
Filing History	Yes	Yes (often with analysis/alerts for late filing)
Credit Score/Risk Rating	No	Yes (e.g., 1-100 score, low/medium/high risk band)
Recommended Credit Limit	No	Yes (a suggested maximum exposure)
Payment History (DBT)	No	Yes (crucial data on how they pay other suppliers)
CCJ & Adverse Data	No (requires separate check)	Yes (consolidated in one place)
Parent/Group Structure	Limited	Yes (detailed view of the full corporate family)
Financials	Yes (raw filed accounts)	Yes (often with key ratios and 5-year trends)

Step 3: Don't Forget Trade References

For a particularly large new client, or one where the data is thin (e.g., a very new company), ask for one or two trade references. This means asking them for the contact details of a couple of their current suppliers.

When you call the referee, be polite and explain you're doing standard due diligence. Ask questions like:

"How long have you been working with [Client Name]?"
"What are your agreed payment terms, and do they generally meet them?"
"Have you ever had to put their account on hold for non-payment?"

A client who readily provides good references is showing confidence in their payment history. A client who refuses is telling you everything you need to know.

You've Done the Check... Now What? Interpreting the Results

The report is only useful if you act on it. Think of it as a traffic light system for your onboarding process.

Green Light: Good Report

The company has a high credit score, a clean record, and a good payment history. You can proceed with confidence. This doesn't mean you can be complacent. You still need to issue clear, accurate invoices and have a process for following up if they're late.

Amber Light: Mediocre Report

The report shows a few warning signs. Perhaps their DBT is a little high (e.g., 15-20 days), their accounts were filed a week late, or the credit score is just average. You don't necessarily have to walk away, but you should take steps to mitigate your risk:

Ask for partial payment upfront: Request 25-50% of the project value before you start work.
Set a low credit limit: Agree to do an initial, smaller piece of work first to test their payment behaviour.
Use shorter payment terms: Offer 14-day terms instead of your standard 30.

Red Light: Bad Report

The report shows active CCJs, a winding-up petition, a history of dissolved companies for the directors, or a "severe risk" rating. This is a clear signal not to offer credit.

Your options are:

Politely decline the work: "Thank you for the opportunity, but unfortunately we're not able to take on this project at this time." You are not obligated to give a reason.
Insist on 100% upfront payment: The only safe way to proceed is on a pro-forma basis. "Based on our standard new client onboarding, we aren't able to offer credit terms. We would be happy to proceed on a pro-forma basis, with payment in full before work commences."

Credit Checks Are Just the First Step

Vetting your clients is the foundation of good financial management, but it's not the whole story. Once you've established a client is a good credit risk, you still need to manage the relationship professionally to ensure you get paid on time.

This involves:

Clear Terms: Having a simple, clear contract or proposal that states your payment terms (e.g., "Strictly 30 days").
Prompt Invoicing: Sending your invoice the moment the work is complete or the milestone is hit.
Systematic Chasing: Having a defined process for following up on overdue invoices.

Even with well-vetted clients, late payments can happen due to administrative oversight, lost invoices, or internal queries. This is where automating the follow-up process becomes crucial. Tools like InvoiceReminder can handle the entire chasing sequence for you, from gentle nudges before the due date to firm final notices, ensuring you stay on top of receivables without the manual effort and awkward conversations. If a payment becomes seriously late, remember you have rights under The Late Payment of Commercial Debts (Interest) Act 1998 to add interest (currently 8% plus the Bank of England base rate) and fixed compensation sums, but prevention is always better than cure.

Frequently asked questions

How much does a UK business credit check cost?

A basic check using public records like Companies House and The Gazette is completely free. For a comprehensive report from a commercial credit reference agency that includes payment history, CCJ data, and a credit score, you can expect to pay between £10 and £30 for a one-off report.

Do I need the client's permission to run a credit check on their limited company?

No. For a limited company (Ltd) or a public limited company (PLC), the information used in a business credit report is compiled from public records. You do not need their permission. For a sole trader or a small partnership, you are effectively checking the individual's credit, which does require their explicit consent under GDPR.

What's the single biggest red flag on a credit report?

An active County Court Judgement (CCJ) or a winding-up petition. A CCJ proves that another company has already had to sue them to get paid and won. A winding-up petition means a creditor is actively trying to force them into liquidation. Both are extremely serious indicators that you should not offer credit.

How often should I credit check clients?

You should perform a check on every new B2B client before you agree to offer them payment terms. For long-standing, high-value clients, it's good practice to run a fresh check annually or use a monitoring service. A company's financial situation can change quickly, and a good client from last year may be a risk this year.

My client has a bad credit report. Should I refuse to work with them?

Not necessarily. It simply means you should refuse to offer them credit. You can protect your business entirely by asking for payment in full upfront (on a "pro-forma" basis). If they agree, you have the money and have eliminated your risk. If they refuse, you have avoided a likely bad debt.

Can I check the credit of a new director, not just the company?

Yes, credit reference agencies offer director reports. These can be very useful as they show the individual's history, including any previous directorships at companies that have failed or been dissolved. This can highlight a pattern of poor management that might not be visible from the current company's report alone.
