Renters' Rights Act 2025: Implementation Timeline and Transitional Rules

The Renters' Rights Act 2025 received Royal Assent in 2025, but Royal Assent on a UK statute is not the same as commencement. Most substantive provisions of this Act come into force on appointed days set by statutory instrument made by the Secretary of State for Levelling Up, Housing and Communities. This two-stage structure is normal for major legislation — Parliament passes the framework, government chooses operational dates after consulting on the implementing regulations and giving the courts, councils, the database operator, and landlords time to prepare. Until the relevant commencement order is made, the old law continues to apply. The Housing Act 1988 still permits Section 21 no-fault notices, fixed-term assured shorthold tenancies are still valid, and the existing Section 8 grounds remain unchanged. Watch the gov.uk announcements and Hansard for commencement orders — the legislation page at legislation.gov.uk also flags 'not yet in force' next to each section that awaits commencement.

Several preparatory provisions of the Act came into force on Royal Assent or shortly afterwards. These include the framework powers for the Secretary of State to make regulations, to designate the database operator, and to consult on the Decent Homes Standard for private rentals. They also include the offence framework — the criminal offences for letting without a licence, providing false database information, and unlawful eviction are defined and ready to be activated when the operational provisions commence. None of these affect day-to-day landlord and tenant rights yet, but they explain why landlord and council compliance teams have been preparing throughout 2025 and 2026. If you are a landlord, this is the window to update your tenancy templates, get your right-to-rent processes ready, and budget for the database registration fee. If you are a tenant, you do not yet have the new protections — your existing tenancy is still governed by the pre-2025 regime.

The headline change — abolition of Section 21 and conversion of all assured shorthold tenancies to periodic tenancies — commences on a single appointed day expected in late 2026 or 2027. On that day three things happen at once. First, no new Section 21 notices can be served. Second, all existing fixed-term assured shorthold tenancies convert into periodic (rolling) tenancies, regardless of how much of the fixed term remained. Third, the new and expanded Section 8 grounds become available to landlords as the only route to recover possession outside surrender or court forfeiture. There is no transitional window where both regimes run in parallel — the switch is sharp. Section 21 notices that were served before the appointed day and whose claim was issued at court before the appointed day continue under the old rules; everything else falls under the new regime. Landlords planning to recover a property for sale or moving in should consider whether to serve and issue before the changeover (using Section 21) or wait and use the new Ground 1A (sale) or Ground 1 (moving in) after — each route has different notice periods and protected periods.

The new Private Rented Sector Database — a national landlord and property register — opens in two phases. The voluntary phase begins first, allowing landlords to register early and councils to enrol properties already known to them through selective licensing. The mandatory phase begins on a later appointed day; from that day, letting a property in England without registration is a criminal offence punishable by fine and rent repayment order. The database will hold each landlord's identity, their portfolio addresses, their compliance record (gas, electrical, EPC, deposit protection, banning orders), and any criminal convictions or enforcement actions. Tenants will be able to check whether a prospective landlord is registered, and councils will use the database for enforcement targeting. Registration is expected to cost a small annual fee per property. The exact go-live date and fee structure will be set by regulations and confirmed by the operator (likely a designated arm's-length body) before mandatory operation begins.

Awaab's Law — the rules requiring landlords to investigate and remedy specified hazards within fixed timeframes — was introduced for social housing through the Social Housing (Regulation) Act 2023 and extended to the private rented sector through the Renters' Rights Act. The private-sector extension commences by regulations expected in 2026. Once in force, private landlords must investigate a reported damp, mould, or other specified hazard within 14 days, complete emergency repairs within 24 hours of identifying a significant risk, and complete other repairs within a further fixed window. The Decent Homes Standard, currently a non-statutory expectation for social landlords, also extends to private rentals from a date to be appointed — properties that fail the standard cannot be let, and tenants will have a route to enforce through the council and the First-tier Tribunal. The combined effect is that private landlords face the same legal repair obligations as social landlords, with the same penalties for breach.

Three further provisions commence on separate appointed days within the Act: the cap on rent in advance (one month maximum, replacing the unregulated practice of demanding six or twelve months upfront from tenants whose income or credit history was 'risky'); the right to request a pet, which the landlord can only refuse on reasonable grounds and where insurance is offered as a condition; and the strengthened anti-discrimination provisions that make it unlawful to refuse to let or to advertise a property as 'No DSS' or 'no children'. The anti-discrimination provisions are expected to commence on or around the same date as the Section 21 abolition. The pet rights and rent-in-advance caps may commence earlier as standalone reforms. Each has its own consultation and statutory instrument process, so check the legislation.gov.uk status of section 25–28 of the Act before assuming a particular provision applies.

Tenants: keep records of any rent-in-advance demand, deposit protection, gas safety certificates and EPC, and any repair requests you make — once the new regime starts, your access to enhanced remedies (RROs, database evidence, Awaab's Law claims) depends on having documented history. If you receive a Section 21 notice before the appointed day, take advice from Shelter or Citizens Advice; the notice must still meet the four-month minimum, the gas/EPC/deposit prerequisites, and the prescribed form (Form 6A). Landlords: update your tenancy templates so they are ready to drop the fixed-term clause and rely on periodic tenancy from the appointed day; budget for database registration fees; audit your properties against the draft Decent Homes Standard; and review your Section 8 grounds knowledge — once Section 21 goes, every possession claim runs through Section 8. Letting agents should brief clients on both regimes during the transition window so that decisions about renewals and possession are based on the up-to-date timetable.
