Mortgage supervision has shifted from the point of sale to the whole life of the loan. The question is no longer only whether the loan was affordable when it was written, but whether the lender identified and responded appropriately when the customer's circumstances or the rate environment changed.
Affordability at origination
MCOB requires an assessment of whether the customer can afford the mortgage, based on income and committed expenditure, with appropriate verification. Several points recur in supervisory findings.
Income verification. Reliance on declared income, or on income sources that are variable or time-limited, without adequate verification or discounting.
Committed expenditure. Under-capture of existing credit commitments, childcare, maintenance obligations and essential expenditure, particularly where the assessment relies on statistical averages rather than the customer's actual position.
Stress testing. Assessment must consider the effect of plausible future interest rate increases over the relevant period. Stress rates that no longer reflect the plausible range are a straightforward finding.
Term into retirement. Where the term extends beyond expected retirement, the lender must assess income in that period rather than assume continuity.
Interest-only. A credible repayment strategy must be assessed, evidenced and reviewed, not merely recorded.
Payment shock and the end of fixed rate periods
Where a large cohort of customers moves from a low fixed rate to materially higher payments, the lender is expected to have identified the cohort in advance, assessed the likely impact, communicated in good time, and prepared operational capacity for the customers who will need support.
| Stage | Expected lender action |
|---|---|
| Ahead of maturity | Cohort identification, affordability modelling, early communication |
| At maturity | Clear options, accessible routes to discuss, no unnecessary friction |
| Post maturity | Monitoring of arrears emergence in the cohort, proactive contact |
| Support | Forbearance options appropriate to the cause and duration of difficulty |
Arrears and forbearance
Forbearance is judged on whether it works. A defensible approach identifies difficulty early using behavioural indicators, establishes the cause and likely duration, offers options matched to that assessment, documents the customer's understanding, reviews the arrangement at defined points, and considers whether the arrangement resolves or merely defers the position.
Recurrent findings include a single default forbearance tool applied regardless of circumstance, arrangements that leave the balance growing, arrears fees applied in a way that worsens the position, and failure to consider whether the sustainable outcome is a change of product, a term extension or an assisted sale.
Vulnerability in practice
Vulnerability policies are common. Operational identification is less so. What supervision tests is whether front-line staff recognise indicators, whether the system records the characteristic and the adjustment made, whether subsequent contacts reflect that record, and whether outcomes for identified customers are monitored against the wider population.
What the board should see
Origination quality metrics including exceptions to policy and their performance, stress test assumptions and their currency, maturity cohort analysis and payment shock exposure, arrears roll rates and forbearance outcome data, vulnerability identification rates and comparative outcomes, and complaints by root cause.
Our guidance on Consumer Duty outcomes evidence sets out how this data should be presented and challenged.

Frequently Asked Questions
An assessment of whether the customer can afford the mortgage based on verified income and committed expenditure, including stress testing against plausible future interest rate increases and assessment of income where the term extends into retirement.
By assessing and evidencing a credible repayment strategy at origination and reviewing it periodically during the term, with proactive engagement where the strategy appears unlikely to repay the balance.
Advance identification of affected cohorts, modelling of the payment increase, timely and clear communication of options, operational capacity to support customers who need it, and monitoring of arrears emergence in those cohorts.
Early identification of difficulty, assessment of cause and duration, options matched to the customer’s circumstances, documented customer understanding, scheduled review, and an arrangement capable of resolving rather than deferring the position.
By whether front-line staff identify indicators, whether the characteristic and the adjustment are recorded and carried into later contacts, and whether outcomes for those customers are monitored against the wider population.
