For many UK businesses, bad debt does not begin with a missed payment. It often starts much earlier, at the point a customer is approved without a clear view of whether the commitment is realistically affordable.
That is why affordability checks matter. For lenders, landlords, subscription providers and other firms offering credit, payment plans or ongoing services, an affordability assessment can support better decisions, reduce avoidable arrears and strengthen responsible onboarding.
In August, this becomes particularly relevant. Many businesses are managing holiday cover, variable staffing and a push to secure late summer sales before autumn trading begins. In that environment, it is easy for account opening checks to become rushed. A structured affordability process helps maintain consistency when teams are under pressure.
What an affordability check helps you assess
An affordability check is not simply about whether a person wants your product or service. It is about whether the proposed payment is likely to be manageable, based on the information and risk indicators available to your business.
For UK firms, this can form part of a broader due diligence process alongside identity verification, fraud screening and, where relevant, KYC and AML controls. The aim is not to make assumptions about an applicant. It is to make a fair, evidence-based assessment using relevant and proportionate data.
A sound affordability review can help you:
- reduce exposure to non-payment and bad debt
- identify customers who may need different terms or lower limits
- support responsible credit and account approval decisions
- create a more consistent onboarding process across teams
- document the basis for decisions in a clear and auditable way
This is especially important for firms that extend credit, allow deferred payment, offer instalment arrangements or take on customers with ongoing financial commitments.
Why affordability checks matter beyond traditional lending
Affordability assessments are often associated with regulated lenders, but the principle is useful much more widely. Any business that faces payment risk can benefit from checking whether a prospective customer appears able to meet the agreed commitment.
Examples include:
- letting agents and landlords reviewing tenant affordability
- subscription businesses approving higher-value plans
- service providers offering staged payments
- firms opening trade accounts with payment terms
- businesses accepting large orders with delayed settlement
In each case, the core question is similar. Is there enough evidence to support confidence that the customer can keep up with the payment obligation?
In practice, that means affordability should sit alongside customer identity verification and risk scoring, rather than replacing them. A customer may be genuine but still present a heightened risk of arrears. Equally, a customer with acceptable affordability may still require fraud checks and compliance screening.
What to include in a proportionate affordability process
The right level of checking will depend on your sector, your risk appetite and the value of the commitment. A proportionate process is usually the most effective.
1. Confirm identity first
Before assessing affordability, confirm that you are dealing with the right person. Reliable identity verification helps reduce fraud risk and ensures later checks are attached to an accurate customer profile.
For example, mismatched identity details, inconsistent addresses or signs of synthetic identity should be reviewed before moving forward.
2. Review relevant financial indicators
Where appropriate and lawful for your use case, review indicators that help assess whether payments are likely to be sustainable. This may include credit-related data, affordability signals, existing commitments or broader risk markers.
The goal is not to collect excessive data. It is to identify whether the proposed arrangement appears realistic.
3. Match the check to the product or service
A low-value monthly subscription may justify a lighter assessment than a higher-value credit arrangement or tenancy. Your process should reflect the size, duration and risk of the commitment.
4. Record your rationale
If a decision is challenged internally or externally, clear records matter. Document what checks were completed, what risk factors were identified and why the customer was approved, referred or declined.
Practical warning signs for payment risk
Affordability checks are most effective when they sit within a wider payment risk framework. Watch for combinations of issues rather than relying on a single indicator.
Common patterns to review
- the customer is seeking higher limits than expected for their profile
- application details are inconsistent or change repeatedly
- there is urgency to complete onboarding without normal checks
- the requested payment structure appears ambitious for the product type
- available risk data suggests financial strain or over-commitment
None of these points should lead to automatic assumptions. However, they may justify a manual review before terms are agreed.
In August, this is particularly useful for businesses processing applications quickly while key staff are on annual leave. A defined review path helps maintain standards even when decision-makers are rotating.
How affordability checks can reduce bad debt in practice
Used properly, affordability checks can improve outcomes at several stages of the customer journey.
First, they can help prevent unsuitable approvals. That reduces the chance of customers entering agreements they may struggle to maintain.
Second, they can support better account structuring. Instead of a simple yes or no decision, some firms may decide to offer shorter terms, lower limits or upfront payments where risk is higher.
Third, they can improve collections performance. Customers approved on a more realistic basis are generally less likely to fall into early arrears, which reduces internal admin and supports healthier cash flow.
Finally, they help strengthen governance. Businesses that use affordability checks as part of secure, documented onboarding are better placed to show that decisions were made responsibly and consistently.
Building a stronger onboarding process
Affordability should not be treated as a standalone task. It works best when integrated into a wider onboarding and risk framework that includes identity verification, fraud prevention, secure data handling and GDPR-aware processes.
For UK businesses, that means creating a workflow that is accurate, proportionate and practical for day-to-day operations. The strongest processes are usually those that balance speed with control, particularly during busy summer trading periods.
