How much can I borrow for a mortgage in the UK?
Most UK lenders use an income multiple of 4–4.5× your gross annual income (or joint income). On a £50,000 salary that is £200,000–£225,000. Some lenders go to 5× or 5.5× for higher earners or first-time buyers. Your credit score, deposit size and existing debts also affect the offer.
Full answer
UK mortgage affordability is assessed in two ways. Income multiple: typically 4–4.5× single income or combined household income. A £70,000 joint income could borrow £280,000–£315,000. Stress test: lenders must confirm you can afford payments if rates rise by ~3%; this can reduce the maximum below what the multiple suggests. Deposit: a 5% deposit is the minimum (Help to Buy/95% LTV), but 10%+ opens lower rates and better lenders; 40%+ typically gets the keenest rates. Credit score: defaults, CCJs or missed payments will reduce what you are offered or whether you are offered anything at all. Existing debt: personal loans, car finance and credit-card limits are factored into affordability. First-time buyers note: Stamp Duty in England is 0% on the first £425,000 (until 31 March 2025; then £300,000) on purchases up to £500,000.
