Old rules versus new rules after May 2026
After 1 May 2026, the private rented sector in England no longer runs on the old Section 21 plus fixed-term tenancy model. The modern system is periodic tenancies, Section 8 possession grounds, tighter rent increase rules, and faster expectations around serious housing hazards.
The most important change is route selection. A landlord can no longer rely on a new Section 21 notice after 1 May 2026. That means tenants should now ask whether the landlord is using the right modern route before they even start checking the detail.
The same shift applies to rent, tenancy structure, and repairs. The law did not just tweak the old system. It changed the frame tenants should use when they read a notice, a rent demand, or a housing-conditions dispute.

Common questions
- What changed on 1 May 2026?
- That is the key commencement date for the main Renters' Rights Act 2025 reforms in the private rented sector in England. New Section 21 notices ended, tenancies moved to the periodic model, rent increase rules tightened, and the modern Section 8 regime became the main possession route.
- Can a landlord still use Section 21 after 1 May 2026?
- No for any new notice served on or after 1 May 2026. A legacy Section 21 notice served before that date may still matter during the transitional window, but the old route is not available for new notices after the commencement date.
- What is the biggest difference for tenants?
- The biggest change is that landlords can no longer use a no-fault route to end a tenancy. They now need a Section 8 ground, correct notice period, and court process. That gives tenants more scope to challenge a weak claim and more reason to inspect the actual legal route being used.
- Did rent increase rules change too?
- Yes. Rent increases are now locked to the once-per-12-month section 13 route for the main private-sector cases. Landlords must use the correct form and tenants keep the right to challenge at the First-tier Tribunal before the increase takes effect.
- What should I check first if I receive a notice now?
- Check the date, the route used, and the form. If it is a post-1 May 2026 possession case, Section 8 is usually the starting point. If it is a legacy Section 21 notice, date and transitional timing are critical. If there is no real notice and only pressure, the illegal eviction route may be more relevant than either notice checker.
- Do old repair and deposit rules still matter?
- Yes. Deposit protection, prescribed information, repair duties, and damp or mould obligations still matter. What changed is the wider framework around possession, tenancy structure, and some enforcement duties. Old statutory rights were not wiped away, they now sit inside a different possession and tenancy system.
