About StampDutyRate.com
StampDutyRate.com is an independent UK stamp duty reference operated by Digital Signet. Rates are sourced from HMRC for England and Northern Ireland, Revenue Scotland for LBTT and the Welsh Revenue Authority for LTT. No advertising, no lead generation, no commercial bookings.
Why this site exists
UK stamp duty is one tax with three statutory regimes (SDLT for England and Northern Ireland; LBTT for Scotland; LTT for Wales) and at least five buyer-type permutations (standard, first-time buyer, additional property, non-UK resident, and the stacked non-UK-resident-plus-additional combination). Government calculators on gov.uk, revenue.scot and gov.wales each cover one regime in isolation. Lender calculators usually cover only England and only the standard case. Conveyancer pages tend to drift out of date around Budget changes.
StampDutyRate.com exists to compute every regime and every buyer type from a single calculator, with the band-by-band math shown on screen so readers can audit the arithmetic against the statutory rate tables themselves. The post-April-2025 threshold reversion (standard nil-rate £250,000 to £125,000, first-time buyer nil-rate £425,000 to £300,000) and the October 2024 additional-property surcharge change (3% to 5%) both materially shifted the cost of a typical purchase. Lots of conveyancer and lender content still references the pre-April-2025 thresholds; this site is verified against current HMRC publications and Revenue Scotland / WRA pages.
The calculator is the centrepiece. The sub-pages exist to answer the long-tail questions the calculator does not surface on its own: how a first-time buyer compares at a specific price, when the £500,000 FTB cliff bites, how to claim back the additional-property surcharge if you replace your main residence, why Scotland's ADS at 8% on the full price is structurally more punishing than England's 5% marginal surcharge at the same price.
Who builds this
StampDutyRate.com is built and operated by Oliver Wakefield-Smith, founder of Digital Signet, an independent AI-development studio that builds and runs a portfolio of UK consumer-cost reference sites. Digital Signet is not a law firm, not a conveyancer, not a tax adviser and not a mortgage broker. The work product is reference content sourced from public statutory publications, with the math shown so any reader can audit it.
Sister sites in the same UK-statutory-fee cluster cross-link from the footer. Each site follows the same editorial pattern: one statutory source, math shown on page, no paid placements, no lead generation, dates updated only when reality changes. None of the sister sites act as a sales funnel for StampDutyRate or vice versa.

Contact and corrections
Spotted a stale figure, broken band table or out-of-date worked example? Email Digital Signet at [email protected] with the URL and the source you would like cited. Corrections are usually made within 5 business days; if the change is statutory (new Budget, Scottish Budget, Welsh Senedd budget) it is rolled into the next refresh cycle so the LAST_VERIFIED date moves at the same time as the figures.
