Two things make a mortgage application need judgement rather than a computer: income that requires extrapolating, and a credit file with something on it.
Contractors with adverse credit have both.
It narrows the market. It doesn’t close it.
The pool shrinks to lenders that will do contract-based underwriting and accept the adverse — an intersection smaller than either group, populated mainly by specialists.
Which means the six-times propositions are generally off the table. Those lenders are lending to clean files at conservative loan-to-values.
That isn’t the same as saying you can’t borrow well.
How Lenders Grade It in 2026
Recency matters most
More than severity. A settled default four years old affects most applications very little. The same default six months old is a different conversation entirely.
Criteria loosen at intervals
Commonly at twelve, twenty-four and thirty-six months after the worst event. Knowing where you sit against those boundaries changes whether you should apply now.
Severity is graded
Roughly ascending: late payments, defaults, county court judgments, debt management plans, individual voluntary arrangements, bankruptcy, repossession. Missed mortgage payments are treated far more seriously than unsecured arrears.
Pattern counts
One event with a clear explanation reads very differently from repeated difficulty over several years.
Deposit compensates
More than anything else on this list. The difference between a 10% and a 25% deposit on an adverse case is often the difference between a handful of options and a reasonable choice.
Case Studies
Case Study 1: Marek – Missed Payment Between Contracts, Peterborough
Marek missed a direct debit during a two-month gap between assignments eighteen months earlier.
Left unexplained, an underwriter had to assume the worst reading. A short factual note and evidence the account was brought back into order made it a minor issue.
Case Study 2: Claire – Close to a Boundary, Wakefield
Claire’s default was twenty-two months old when she started looking.
Waiting until it passed the two-year mark materially widened the lenders available to her, at no cost beyond a short delay.
Case Study 3: Femi – Historic and Minor, Slough
Femi assumed a four-year-old settled default confined him to specialist pricing.
Checking mainstream criteria first showed several would take the case, saving a substantial premium over his fixed term.
Why Outcomes Differ
- How recent the worst event is
- Severity, and whether it was secured or unsecured
- Whether there’s a pattern or a single incident
- Deposit size
- Conduct since the event
- Contract strength and unexpired term
