Identify the credit product and governing rules
The starting point is the actual legal and contractual arrangement, not the marketing label. Record the creditor, borrower, repayment structure, amount, term, fees and how the customer becomes bound. Determine whether the transaction falls within the relevant consumer credit rules, and identify any exemption or special regime using the operative legislation. A conclusion reached for one type of credit cannot automatically be applied to an instalment loan, overdraft or revolving account. Also distinguish a customer application from a later material increase in available credit. The creditor should document which entity is legally responsible for the assessment when an intermediary, merchant or technology provider collects information. A reproducible scope decision is necessary before selecting evidence, a decision model or a disclosure process.
BNPL structures must be classified before assessment
Buy now, pay later is a commercial description covering distinct arrangements. A third-party lender financing a purchase, a supplier offering deferred payment and an arrangement with fees or late charges may not have identical legal treatment. Establish the contracting creditor, whether an agreement is regulated, the instalment schedule and who carries repayment risk. A merchant's eligibility widget may not be the legal creditor's full assessment. Capture whether the consumer already has other instalment plans and how concurrent obligations affect repayment capacity. A zero-interest description does not establish exemption from every creditworthiness or consumer-protection obligation. Keep evidence of the actual product terms and the legal scope determination.
A creditworthiness score does not settle affordability
A model predicting the probability of missed payments can provide useful information, but may not show whether payments will place the customer under financial strain. Credit history can be thin, income variable and household expenditure difficult to estimate. Establish what is being predicted, how the proposed repayment schedule affects the customer and whether the data are sufficient for the legal standard in question. A lender should avoid concluding that an apparently low-risk applicant can afford all offered amounts. Existing debt service, essential costs and repayment timing may be relevant even where an individual instalment is modest. Where information conflicts, define an escalation procedure and keep the reasoned outcome. The decision should connect the evidence to the proposed commitment rather than merely repeat a numerical threshold.
EU CCD2 timing and national implementation
Directive (EU) 2023/2225 Article 18 establishes a revised creditworthiness framework intended to prevent irresponsible lending, while Article 19 addresses database access. Member States had to transpose the directive by 20 November 2025, and national implementing measures generally apply from 20 November 2026, subject to transition. In October 2026 the revised requirements should not be described as already universally applicable. Existing national law and any national implementing act must be examined for the agreement date and product. Differences in domestic legislation can affect information sources, verification, consumer rights and the consequences of an unfavourable assessment. Maintain a register showing which national rules apply and when changes take effect. A general EU explanation cannot replace the operative Member State rules.
UK FCA responsible lending approach
FCA CONC 5.2A requires a reasonable creditworthiness assessment for relevant regulated consumer credit agreements and certain significant credit increases. The assessment covers both the risk that the consumer will not repay on time and the affordability risk to the consumer. Its depth depends on circumstances and relevant proportionality requirements rather than an identical checklist for every application. Existing information may be useful where it remains reliable, but contradictory evidence and known financial difficulty warrant attention. Verify the exact product scope and exceptions instead of assuming that a loan's size or digital application route decides the matter. Record any income, expenditure or existing obligation estimates and the justification for reliance on them. Automated approval does not remove the creditor's duties.
US requirements are not a copy of EU or UK rules
United States requirements depend on the product, creditor and applicable federal and state law. ECOA and Regulation B govern discriminatory credit evaluation and adverse-action notices under their conditions. Certain residential mortgage transactions have specific ability-to-repay obligations under Regulation Z section 1026.43. Other consumer products do not automatically inherit the same mortgage test or the UK's CONC 5.2A proportionality provisions. Use consumer reports only with the relevant permissible purpose and observe applicable Fair Credit Reporting Act duties. If an application is denied, ensure any required explanation reflects the factors actually used in the decision. A cross-border decision system must distinguish the substantive assessment from separate notice and reporting responsibilities.
Short repayment schedules and cumulative exposure
BNPL instalments are often small and spread over weeks, which can make them appear manageable in isolation. The important question is how all due payments align with the consumer's income and existing commitments. Several simultaneous plans can create payment bunching even when each individual transaction has a modest face value. A creditworthiness process should use relevant obligations and data available lawfully and proportionately under the applicable regime. Avoid assuming a low historic default rate proves every new purchase affordable. Model testing should cover repeat purchases, missed instalments, refund delays, returned goods, split merchant orders and recent unpaid obligations. Clear assignment of responsibility among merchants, intermediaries and lenders is important when a transaction changes after checkout.
Operational evidence and independent testing
Preserve the product and borrower context, information source, observation date, assumptions, policy version, automated model build, reviewer authority, decision and customer communications. Distinguish a declared value from a verified value or a statistical estimate. Test scenarios with irregular income, recently opened debt, disputed bureau information, multiple obligations and unexpected payment dates. Review fairness, data accuracy, exceptions, consumer complaints and repayment stress for indications that the assessment process is failing. Changes to legislation, product terms or model features require controlled review and regression testing. A record should make it possible to reproduce why the decision was reasonable at the time, without retaining unnecessary personal information indefinitely. Vendor outputs should be reviewed as part of creditor accountability.
Frequently asked questions
Does a small payment automatically remove the assessment duty?
No. The legal scope and any exemption depend on the jurisdiction and credit product.
Is a credit score alone sufficient?
Not necessarily. The legal assessment may require other relevant information about repayment capacity.
When do revised CCD2 implementing provisions generally apply?
From 20 November 2026, with national transitional arrangements.
