About this site

Tenancy Tools Online is a small, independent set of free calculators for landlords and tenants in England. It exists to give clear answers without clutter.

Every tool is free. There are no accounts, no paid tiers and no upsell. The site may show advertising in future to cover its costs, and if so it will say so here.

The calculators follow the Housing Act 1988, the Housing Act 2004, the Tenant Fees Act 2019 and the Renters' Rights Act 2025, plus official GOV.UK guidance. See how we calculate and our sources.
