Most landlords found out about the Renters' Rights Act 2025 from a headline, not a briefing. That's a problem, because the Act doesn't tweak the old rules — it replaces the framework most UK landlords have operated under for two decades, and the practical change is not a single new document but a genuinely different tenancy model.
The Core Changes That Took Effect
The Act received Royal Assent in October 2025, with the first major tenancy-reform phase taking effect on 1 May 2026. From that date: most existing assured shorthold tenancies automatically became assured periodic tenancies, and new tenancies are periodic rather than fixed-term. Section 21 can no longer be served — possession now requires a valid statutory ground and the correct process. Written advertising must state a specific asking rent, with rental bidding above that figure prohibited. Rent-in-advance rules changed, restricting what can be requested before and after signing. Rent increases for assured periodic tenancies now use the statutory section 13 process with its own prescribed form and notice period. Landlords must consider written pet requests within a 28-day framework rather than refusing at will, and new rules prohibit discriminating against applicants because they have children or receive benefits.
What You Didn't Need to Do
For a tenancy created before 1 May 2026 that already had a written record of its terms, you did not generally need to replace the tenancy agreement just because it became periodic. Instead, the government required the official Renters' Rights Act Information Sheet to be supplied to all named tenants by 31 May 2026 — a real, dated obligation, but a different one than rewriting every agreement in your portfolio.
The Timeline Beyond May 2026
This didn't all happen at once, and it isn't finished. Royal Assent came 27 October 2025. Certain new local-authority enforcement powers came into force 27 December 2025. The core Phase 1 reforms took effect 1 May 2026, with the Information Sheet deadline following on 31 May 2026. From late 2026, Phase 2 begins a staged, regional rollout of the PRS Database. A 2028 milestone is set for mandatory landlord sign-up to the PRS Landlord Ombudsman after it scales up. Awaab's Law and the Decent Homes Standard are intended to extend to the private rented sector eventually, but their implementation timing remains subject to consultation — don't treat any of these later phases as settled dates the way 1 May 2026 now is.
Who Should Take Extra Care Before Assuming the Standard Rules Apply
Resident landlords and lodger arrangements, purpose-built student accommodation, very high or very low rent arrangements outside normal assured periodic tenancy conditions, business tenancies, holiday lets, and long leases all sit outside the standard framework or follow different rules — as do any properties already involved in licensing, HMO, deposit, or enforcement issues. If your situation touches any of these, the general rules covered here are a starting point, not the final answer.
