Estimates only — not tax, legal or financial advice. 2026/27 rates per gov.uk: nil band to £125,000; first-time buyer relief to £300,000 and withdrawn entirely above £500,000; the additional-property surcharge is 5% on every band and applies from £40,000; the non-UK-resident surcharge adds 2% on the whole price and STACKS on top of the additional-property rates. Fee estimates (legal, survey, mortgage, Land Registry) are typical figures, not quotes. Confirm with your solicitor.
