The Renters’ Rights Act 2026: what changed, explained

The Renters’ Rights Act 2025 is the biggest reform of private renting in England in a generation. Its main provisions took effect on 1 May 2026, reshaping how tenancies work, how rent can be increased and how possession is obtained. This guide explains the changes in plain English – for both landlords and tenants – and links to free calculators for the parts where the new rules turn on getting a date right.

The end of Section 21 and fixed terms

The headline change is the abolition of Section 21 “no-fault” evictions. From 1 May 2026 a landlord can no longer end a tenancy simply by giving notice without a reason; possession now runs entirely through the Section 8 grounds. At the same time, fixed terms were abolished: every assured tenancy is now periodic, with rent periods of no more than a month, whatever the written agreement says. Existing assured shorthold tenancies converted automatically to the new periodic system.

For tenants this means more security and the freedom to leave at any time on notice. For landlords it means planning around the Section 8 grounds and the new notice periods rather than the old certainty of a fixed term.

Rent increases: Section 13 only, once a year

Rent increases changed fundamentally. A rent increase is now valid only if it follows the Section 13 procedure – served on the prescribed Form 4A, with at least two months’ notice, taking effect on a rent due date – and it can happen only once every 12 months. Rent review clauses in tenancy agreements, including index-linked and fixed-uplift clauses, no longer have any effect, even in agreements signed before the Act.

Because the new rules put all the weight on getting the notice right, a single date error can void the whole increase. These tools and guides cover it:

Challenging a rent increase at the tribunal

Tenants can still refer a proposed increase to the First-tier Tribunal, but the balance shifted in their favour. The tribunal can now keep the rent the same or reduce it to the open market rate, but it can never set it higher than the landlord proposed – removing the old risk that put tenants off challenging. Any increase the tribunal does allow takes effect from the next rent payment date after its decision, not backdated, and can be deferred for undue hardship. The catch is the deadline: the tenant must apply before the effective date on the notice.

Ending a tenancy: the tenant’s notice

Because every tenancy is now periodic, a tenant can end an assured tenancy at any time by giving at least two months’ written notice, timed to end at the end of a rent period. There is no fixed term to sit out. Tenancies that began before 1 May 2026 and allowed a shorter notice period keep that shorter period, and a landlord can always agree an earlier surrender.

Possession and the Section 8 grounds

With Section 21 gone, every possession claim now relies on a Section 8 ground, and the grounds were expanded and re-timed. New grounds were added – including a ground for landlords who need to sell, and one for student HMOs – and existing grounds were amended. The most significant change for rent arrears is that the mandatory Ground 8 threshold rose to three months’ rent (or 13 weeks’ for weekly and fortnightly tenancies), the arrears must be met both when notice is served and at the hearing, and the notice period increased to four weeks.

Bidding, pets, discrimination and rent in advance

The Act also brought a set of tenant protections around how properties are let:

• No rental bidding wars. Landlords and agents must advertise a rent and cannot invite or accept offers above it.
• The right to request a pet. A tenant can ask to keep a pet and the landlord must consider the request and respond within a set time, and cannot refuse unreasonably.
• No blanket discrimination. Blanket bans on tenants who receive benefits or who have children are unlawful; applicants must be assessed individually on affordability and suitability.
• Limits on rent in advance. Landlords cannot demand large sums of rent up front before a tenancy begins.

Exact procedures and penalties for these sit in the regulations and guidance – check the current detail on GOV.UK before relying on any one point.

What is still to come

Not everything in the Act started on 1 May 2026. Several major measures are being introduced in later phases on a rolling timetable, and the dates have shifted as regulations are made, so treat any specific date as provisional:

• The Private Rented Sector Database – a register of landlords and properties.
• A private rented sector Ombudsman – free, binding complaint resolution for tenants, expected after 2026.
• The Decent Homes Standard extended to private rentals, phased in later this decade.
• Awaab’s Law extended to the private sector, setting timescales to fix serious hazards such as damp and mould, with the detail set by regulations.
