Most UK lenders cap borrowing at roughly 4.5 times your annual income (sometimes more for higher earners), then run an affordability check on your spending. A larger deposit lowers your loan-to-value and unlocks better rates. Use the UK calculator to turn a loan size into a monthly payment.
How much can I borrow for a UK mortgage?
Most UK lenders cap borrowing at around 4.5 times your annual income (some go to 5–5.5× for higher earners or specific schemes). They then run an affordability check on your regular spending and commitments. Turn a loan size into a monthly payment in the UK mortgage calculator.
What affects how much you can borrow?
- Income: salary, plus a portion of bonuses or self-employed profit.
- Outgoings: credit commitments, childcare, and regular costs.
- Deposit: a bigger deposit lowers your loan-to-value and improves rates.
- Term: a longer term lowers monthly payments (but costs more interest).
How to borrow more
Reduce other credit commitments, apply with a joint income, save a larger deposit, or consider a longer term. The UK has no mortgage insurance — instead, higher loan-to-values carry higher rates, so a bigger deposit both raises borrowing power and lowers your rate.
