Frequently asked questions
How much can I borrow based on my salary?
UK mortgage lenders typically offer 4 to 4.5 times annual salary. On a £40,000 salary, you can borrow approximately £160,000–£180,000. On £60,000, approximately £240,000–£270,000. Some lenders offer up to 5× for high earners or professionals.
What is the minimum deposit for a mortgage in the UK?
The minimum deposit is typically 5% (95% LTV mortgage). However, most lenders require at least 10% for standard rates. First-time buyers can use the government mortgage guarantee scheme for 5% deposits on properties up to £600,000.
How do I improve my mortgage affordability?
Reduce monthly debt commitments (credit cards, car finance), avoid taking on new credit 6 months before applying, save a larger deposit to reduce LTV, and consider paying off existing debts. Pension contributions may help by reducing taxable income for some affordability calculations.
How UK mortgage affordability is calculated in 2025-26
UK mortgage lenders use two methods to determine how much you can borrow: the income multiple (a quick ceiling based on salary) and a full affordability assessment (stress-tested against your actual income and outgoings).
The income multiple is the starting point. Most high-street lenders cap at 4.5× your gross annual salary for single applicants, or 4.5× combined income for joint mortgages. The FCA's mortgage market review requires all lenders to verify that the mortgage is affordable even if rates rise by 3 percentage points.
Monthly repayments depend on three variables: loan size, interest rate, and term. The figures on this site use a 5% annual rate and 25-year term as a realistic benchmark for 2025-26. If you secure a fixed rate below 5%, your payments will be lower; if rates rise, they will be higher.
