Deposit for a £600,000 House UK 2026 — How Much Do You Need?

Buying a £600,000 house requires a minimum deposit of ££30,000 (5%), though 10% (££60,000) gets you better rates. Full breakdown of costs and monthly payments.

Mortgage information is general guidance only. Mortgages are regulated by the FCA. YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON YOUR MORTGAGE. Consult an FCA-regulated mortgage adviser before making decisions.

To buy a £600,000 house you need a minimum deposit of ££30,000 (5%), but most buyers put down at least ££60,000 (10%) to access better mortgage rates and reduce monthly payments. On top of the deposit, budget for stamp duty (££20,000 for standard buyers, ££20,000 for first-time buyers) plus solicitor and survey fees of around £2,500–£4,000.

Deposit Options for a £600,000 House

Deposit Amount Loan amount Monthly payment (4.5%, 25yr) LTV
5% £30,000 £570,000 £3,168 95%
10% £60,000 £540,000 £3,001 90%
15% £90,000 £510,000 £2,835 85%
20% £120,000 £480,000 £2,668 80%
25% £150,000 £450,000 £2,501 75%

A larger deposit reduces your loan-to-value (LTV). Lower LTV typically means better interest rates — which can save thousands over the mortgage term.
