About TenancyTools.uk

TenancyTools.uk exists because the Renters’ Rights Act turned routine tenancy admin into date arithmetic with expensive failure modes – and because most of the information published about it is either legal commentary written for lawyers, or out-of-date articles describing rules that stopped applying on 1 May 2026.

This site takes a different approach: free interactive calculators that apply the statutory rules to your actual dates, sitting alongside guides written in plain English for the people the rules actually affect – landlords, letting agents, resident directors and tenants.

Who builds it

TenancyTools.uk is built and maintained by James, who runs a property management business in the West Midlands working with landlords, resident management companies and tenants. The tools on this site come from the same questions that come up in that work every week: when can this notice be served, what date goes on the form, is this increase valid, what happens if the tenant challenges it.

That practical grounding shapes how the site is written. The worked examples use the situations that actually occur – mid-month service dates, rent due on awkward days, notices that arrive late in the post – rather than the tidy scenarios that only exist in textbooks.

How accuracy is maintained

• Every rule is checked against the primary sources: the Housing Act 1988 as amended, the Renters’ Rights Act 2025, and the current prescribed forms and guidance on GOV.UK.
• Every page carries a visible “last reviewed” date, and pages are re-reviewed whenever the rules or prescribed forms change – including as Phase 2 of the reforms is implemented later in 2026.
• Calculator logic is tested against published worked examples and edge cases before release.
• If you spot an error, please tell us – corrections are made promptly and noted on the page.

What this site is not

TenancyTools.uk provides general guidance and calculation tools. It is not a law firm and nothing on the site is legal advice. Tenancy disputes turn on individual facts, and where the outcome matters – a possession claim, a tribunal referral, a deposit dispute – you should take advice from a solicitor or a professional adviser. The calculators tell you what the statutory date rules produce for the dates you enter; they cannot tell you whether serving the notice is the right decision.

Coverage

The rules described on this site apply to assured periodic tenancies in England. Wales, Scotland and Northern Ireland have separate tenancy regimes, and pages state their scope where it matters.
