UK Mortgage Affordability Index
As of June 2026, the most generous mainstream UK lender will lend about 33.6% more than the least generous to the same borrower. A £50,000 earner can borrow £224,500 or £300,000 — a £75,500 swing — based purely on which lender they approach, with no change to income, deposit or circumstances.

Why the same income produces such different offers
The single biggest driver is the income multiple. Mainstream lenders cluster around 4.49× income, but a handful stretch much further:
- HSBC Premier6.5×
- Nationwide (Helping Hand)6.0×
- Barclays6.0×
- NatWest (higher income)6.0×
- Leeds BS (Income Plus)6.0×
- Aldermore6.0×
Beyond the headline multiple, lenders differ on how they treat overtime, bonus and commission, self-employed and contractor income, and existing credit commitments — which is why a whole-of-market comparison can be worth tens of thousands in borrowing power.

Methodology
- Source:each lender's published income-multiple (loan-to-income) ceiling from their intermediary lending criteria, as of June 2026 — reflecting the 2025 relaxation of the regulatory LTI cap.
- Scenario: single employed applicant, 25-year repayment term, no dependants and no additional debts. A representative sample of leading high-street and specialist lenders is taken at each income band.
- Figures:"lowest", "median" and "highest" are the smallest, middle and largest maximum loan across the sampled lenders for that income. The gap is the cash difference between highest and lowest.
- Updated: refreshed monthly as lender criteria and rates change.
