How big a mortgage can I get on a £155,000 salary?

Typically around £620,000 to £698,000, based on the common 4x to 4.5x income multiple lenders apply (4 to 4.5 times £155,000). Some lenders stretch further for high earners with clean credit, but affordability checks on outgoings can pull the figure down.

Full answer

Most UK lenders cap borrowing at roughly 4 to 4.5 times gross annual income, so on a £155,000 salary you could typically borrow between £620,000 and £698,000. A handful of lenders offer 5x for high earners with strong credit, potentially reaching £775,000, though this depends heavily on outgoings, other debts and the lender's own affordability model. Worked example: borrowing £698,000 over 25 years at 5.0% costs about £4,080 a month. Take-home pay on a £155,000 salary is roughly £7,952 a month for 2026/27 after Income Tax and National Insurance (including the Personal Allowance taper, which reduces the tax-free allowance by £1 for every £2 earned above £100,000), so this payment is around 51% of net income -- lenders generally prefer mortgage costs below 35-40% of net pay, meaning the maximum multiple is rarely achievable in practice without a smaller loan or larger deposit. Adding a deposit increases the property price you can target: £698,000 borrowing plus a £150,000 deposit buys a property around £848,000. At this income level lenders will also scrutinise bonus, commission or variable pay treatment closely. Use the mortgage affordability calculator to factor in your deposit and outgoings, and the take-home pay calculator to check your real monthly budget.
