The bidding ban means you cannot test the market upwards. The one-increase-per-year rule means underpricing costs you 12 months of income. And tenants can now challenge the initial rent at the First-tier Tribunal within the first six months of a new tenancy. If the tribunal decides you have overpriced, it will reduce the rent. It cannot increase it.

The government published the official Renters' Rights Act Information Sheet 2026 on 20 March 2026. If you are a landlord with existing tenants, you are legally required to send them this document by 31 May 2026. Fines for non-compliance start at £4,000.
