Section 21 abolished: a tenant's action page

One-sentence answer

Section 21 stopped being available for new and existing assured shorthold tenancies on 1 May 2026 in England, but pre-1 May 2026 notices live in a transitional window — so the first thing you do with any "Section 21" or "two months' notice" letter in 2026 is check the date and the court timing, not pack a box.

What "Section 21 abolished" actually means

Until 1 May 2026, a landlord on an assured shorthold tenancy in England could end the tenancy without fault on two months' notice in the prescribed form (Form 6A), provided certain pre-conditions were met — deposit protected, prescribed information given, gas safety certificate, How to Rent guide. That was Section 21 of the Housing Act 1988.

From 1 May 2026 the Renters' Rights Act 2024 took that away:

• No new Section 21 notices can be served. The form is dead.
• Existing ASTs converted to assured periodic tenancies on the cut-off date. The landlord now needs a Section 8 ground to end the tenancy.
• Pre-1 May 2026 notices still work, but only under transitional rules. (Source: GOV.UK — Possession notices before 1 May 2026.)

The transitional question: when was the notice served?

This is the single test that decides which rules apply.

Critical date on the notice: the date the notice was served on you — not the date the landlord typed it, not the date the envelope is post-marked. "Served" usually means the date you actually received it (or the deemed date in the agreement's service clause).

• Served on or before 30 April 2026: transitional Section 21. Go to the next section.
• Served on or after 1 May 2026: cannot be a Section 21. If it is presented as one, it is invalid.

If the date on the notice is missing or has been altered, treat the notice as suspect and ask the landlord in writing for the original service date.

Notices served before 1 May 2026

A Section 21 served in the transitional window still works, but it has a use-by date. Under the GOV.UK pre-1 May 2026 possession guidance, the landlord must start a court possession claim within the prescribed window measured from service. After that window, the notice expires and the landlord must start again — under the new regime, which means a Section 8 with a real ground.

What to check on a transitional Section 21:

1. Was the deposit protected within 30 days of receipt? If not, the Section 21 is invalid regardless of date.
2. Was the prescribed information given? If not, ditto.
3. Was the gas safety certificate given before move-in? If not, the Section 21 can be challenged.
4. Was the most recent How to Rent guide given? If not, defective.
5. Has the court window expired? Compare service date to the pre-1 May guidance. Expired notices are dead.

Notices dated on or after 1 May 2026

There is no such thing as a valid Section 21 dated on or after 1 May 2026. If your landlord has handed you a "two months' notice" dated 1 May 2026 or later, it is one of two things:

• a mis-described Section 8 notice — possible if the substance (a Section 8 ground, the right Form 3, the right notice period) is actually there; or
• a legally meaningless letter — far more common, especially from smaller landlords or agents working off old templates.

Run the notice through the validity test on the pillar (Renters' Rights Act 2026: tenant's guide to your new rights). If no Section 8 ground is named, no notice period is specified, and no Form 3 is used, the letter is meaningless and you are not under any duty to leave. Reply in writing acknowledging receipt and asking the landlord to confirm which Section 8 ground they intend to rely on. That reply is your paper trail.

What landlords sometimes do instead

Three workarounds, and how they fail:

1. "Mutual surrender." Landlord asks you to sign a one-line agreement that the tenancy is ending. Surrendering ends the tenancy by mutual consent — but you give up your right to stay, your defences, and your bargaining position on the deposit. Don't sign without a tenancy review.
2. New "fixed term" you have to sign or leave. Fixed terms ended on 1 May 2026. Your landlord can offer one; you do not have to accept it; refusing it does not end your tenancy.
3. Rent increase you can't afford as a constructive way to push you out. Rent rises must use a Section 13 notice in the prescribed form, no more than once a year, and you can challenge the increase at the First-tier Tribunal (see Periodic tenancies after May 2026: how the new rolling regime works).

Your week-by-week action plan

Week 1:

• Photograph the notice (front, back, envelope, postmark).
• Locate the deposit certificate, prescribed information, gas safety certificate, and How to Rent guide.
• Send a short written acknowledgement: "I have received the notice dated [DATE]. Please confirm in writing which Section 8 ground you intend to rely on, and the notice period for that ground."
• Keep paying rent on time.

Week 2:

• Run the five-question test on the pillar (Renters' Rights Act 2026: tenant's guide to your new rights).
• If anything fails, send a paid tenancy review request through Tenancy agreement review.
• If the notice is transitional (pre-1 May 2026), diary the end of the court window.

Weeks 3–4:

• Continue paying rent.
• If the landlord starts a court claim, get representation.
• If the landlord goes quiet, the notice probably wasn't viable.
