UK Landlord Tools is a set of free, plain-English calculators and guides built for UK landlords and property investors - covering everything from rental yield and stamp duty to Section 24 tax, capital gains and the upcoming April 2027 changes to property income tax.
The site is built and maintained by Tim, a UK-based developer who also runs UK Money Tools, a sister site offering financial calculators trusted by thousands of UK users. Both sites share the same approach: clear, accurate tools with no jargon, no sign-up, and no sales pitch - just straightforward answers to real questions.
UK property tax and lettings law changes constantly - and most calculators online are out of date, oversimplified, or hide the real numbers behind a paywall or a sales funnel. UK Landlord Tools aims to be different: every figure is shown in full, every calculation runs entirely in your browser, and the site is updated as soon as the rules change - including the upcoming April 2027 property income tax rate increases and the abolition of Section 21 evictions under the Renters' Rights Act 2025.
