Home Financing Costs in the UK: What to Budget For
Buying a home in the UK involves more than the mortgage payment itself — Stamp Duty Land Tax, the deposit, and ongoing costs all need to be budgeted for before you commit.
Stamp Duty Land Tax (SDLT)
SDLT is a tax paid by the buyer on property purchases in England and Northern Ireland (Scotland and Wales have their own equivalents, LBTT and LTT). For a main residence, no SDLT is due on the first £125,000 of the purchase price, with rising bands above that. First-time buyers get relief: no SDLT on the first £300,000 of a home costing up to £500,000. Above £500,000, first-time buyer relief no longer applies. Use the Home Financing Calculator on this site to estimate SDLT alongside your mortgage payment.
The Deposit and the Lifetime ISA Bonus
Most mortgage lenders require a deposit of at least 5-10% of the property value, with better rates typically available above 25%. A Lifetime ISA (LISA) is a dedicated tool for this: save up to £4,000 a year toward a first home costing £450,000 or less, and the government adds a 25% bonus on top — up to £1,000 a year in free money — as long as you're between 18 and 39 when you open it.
Ongoing Costs Beyond the Mortgage
Budget for buildings insurance (usually required by the lender), Council Tax, maintenance, and — for leasehold flats — ground rent and service charges, which can add hundreds of pounds a month on top of the mortgage payment itself.
