Stamp Duty UK Estimator

Stamp Duty UK Estimator is a Chrome extension that estimates UK land tax (Stamp Duty) for freehold property purchases by individuals. It covers England, Scotland, Wales and Northern Ireland and accounts for factors like first-time buyer status, purchasing an additional property, and whether the property is residential or non-residential. The tool shows a transparent breakdown of the tax calculation and can email the details.

It also offers a beta search for sold prices in England and Wales using HM Land Registry data and includes an attribution statement. Note that figures are estimates subject to tax rules and lender quotes; the app is ad-supported with an option for non-personalised ads.
