Does salary sacrifice affect a mortgage application in the UK?
Yes -- salary sacrifice reduces the gross salary shown on your payslip, which can reduce the amount lenders are willing to lend. Some lenders add the sacrifice amount back when assessing affordability. Always declare your full package to your mortgage broker.
Full answer
Salary sacrifice is an arrangement where you give up a portion of your gross salary in exchange for a non-cash benefit (pension contributions, electric car, cycle to work, childcare vouchers). While it reduces income tax and National Insurance, it can complicate mortgage applications. How salary sacrifice appears on payslips: - Your payslip will show a reduced gross salary -- the salary after the sacrifice amount has been deducted. - Some payslips make this clear with a line showing "salary sacrifice" as a deduction; others simply show the lower figure as the base salary. Impact on mortgage affordability: - Most lenders base maximum borrowing on a multiple of gross income (typically 4x to 4.5x). - If your payslip shows £45,000 when your real package is £50,000 (with £5,000 sacrificed into pension), some lenders will use the lower £45,000 figure. - This could reduce your maximum mortgage offer by £22,500 to £25,000 at a 4.5x multiple. How different lenders treat it: - Some lenders add the salary sacrifice amount back to your income for affordability purposes. - Others accept a letter from your employer confirming your contractual salary before sacrifice. - Mortgage-specific policies vary widely -- a whole-of-market broker is essential. Benefits that commonly affect applications: - Pension salary sacrifice (most common) - Electric car schemes (car allowance vs. company car also affects lenders differently) - Cycle to Work schemes (typically small amounts, less impact) What to do: - Tell your broker about salary sacrifice schemes before submitting applications. - Obtain a salary confirmation letter from your employer showing the full pre-sacrifice contractual salary. - Consider temporarily pausing or reducing salary sacrifice if you are close to a borrowing threshold.
