What is Section 21?
Section 21 of the Housing Act 1988 allows landlords in England to evict tenants without giving any reason. Known as "no fault evictions", these notices require just 2 months' notice and then become mandatory — if the tenant doesn't leave, the court must order possession.
Section 21 notices can be served at any time during a tenancy, regardless of whether the tenant has done anything wrong. The landlord doesn't need to prove rent arrears, property damage, or any other breach. They simply need to follow the correct procedure and wait 2 months.
This system has made private renting fundamentally insecure. Over 11 million private renters in England live with the constant knowledge that they could be forced out of their home with minimal notice and no wrongdoing on their part.
Section 21 is also used as a weapon against tenants who complain. Rather than fix a leaking roof or broken boiler, some landlords simply serve a Section 21 notice to get rid of "difficult" tenants.
Key Dates: When Section 21 Ends
The timeline for Section 21 abolition is now confirmed:
27 October 2025: Royal Assent
The Renters' Rights Act 2025 received Royal Assent and became law.
30 April 2026: Last Day for New Section 21 Notices
This is the final day landlords can serve new Section 21 notices. Any Section 21 notice served on or after 1 May 2026 will be completely invalid.
1 May 2026: Section 21 Abolished
From this date:
- No new Section 21 notices can be served
- All existing fixed-term tenancies become periodic
- All new tenancies must be periodic from day one
- Landlords can only evict using Section 8 grounds
What Happens to Existing Section 21 Notices?
Section 21 notices served before 1 May 2026 remain valid and can still be used to obtain possession orders. However, once 1 May arrives, no new Section 21 notices can be served, even if the old one expires or becomes invalid.
This creates a narrow window: if you're a tenant who received a Section 21 notice in early 2026, and you successfully challenge it in court or it expires, your landlord cannot serve a replacement Section 21 notice after 1 May 2026.
What Replaces Section 21?
From 1 May 2026, landlords can only evict tenants using Section 8 grounds for possession. These are specific reasons defined in law, such as:
Landlord Circumstances (Mandatory Grounds)
- Ground 1: Landlord or family member wants to move in (4 months' notice, 12-month protection period)
- Ground 1A: Landlord wants to sell the property (4 months' notice, 12-month protection period)
- Ground 2: Mortgage lender repossessing (4 months' notice)
Tenant Fault (Notice Periods Vary)
- Ground 8: Serious rent arrears (3+ months, 4 weeks' notice) — Mandatory
- Ground 10: Any rent arrears — Discretionary
- Ground 12: Breach of tenancy terms (2 weeks' notice) — Discretionary
- Ground 14: Anti-social behaviour (immediate proceedings) — Discretionary
New Protections for Tenants
The expanded Section 8 system includes important safeguards:
- 12-month protection period — landlords cannot use Grounds 1 or 1A for the first year of any new tenancy
- 4 months' notice for landlord circumstances (instead of 2 months under Section 21)
- Anti-abuse measures — landlords using Ground 1 or 1A cannot re-let the property for 12 months
- Higher rent arrears threshold — mandatory eviction only after 3 months' arrears (up from 2 months)
Impact on Tenants: What This Means for You
The Good News
- No more arbitrary evictions — your landlord must have a valid legal reason to evict you
- Complaint protection — you can report disrepair or poor conditions without fear of retaliatory eviction
- Longer notice periods — 4 months instead of 2 if your landlord wants to move in or sell
- 12-month protection — new tenants get a full year before landlords can use possession grounds 1 or 1A
- Court protection — discretionary grounds mean judges can refuse eviction even if the technical ground is met
The Challenges
- Rent increases may become more common as landlords lose the Section 21 "nuclear option"
- Stricter referencing — landlords may become more selective about tenants
- Ground 8 focus — rent arrears evictions may increase as this becomes the main mandatory ground
Periodic Tenancies: What Changes?
From 1 May 2026, all tenancies become periodic (rolling month-to-month or week-to-week). This means:
- No more fixed terms — you're not locked in for 6-12 months
- 2 months' notice to quit — you can leave with 2 months' notice anytime
- Flexibility — easier to move for work, relationships, or better housing
- Same security — landlords still need valid grounds to evict you
Impact on Landlords: Adapting to the New System
What Landlords Lose
- Quick exit option — no more 2-month no-fault evictions
- Fixed-term security — tenants can now leave with 2 months' notice anytime
- Retaliatory evictions — can't remove tenants who complain about conditions
What Landlords Gain
- Clearer grounds — expanded and updated Section 8 grounds cover legitimate scenarios
- Simpler system — one set of rules instead of complex AST variations
- Professional tenants — stable system attracts better long-term tenants
- Legitimate sale/occupation rights — Ground 1A (sale) and Ground 1 (occupation) remain available with proper protections
Key Changes for Landlords
Evidence requirements: You'll need proper evidence for any eviction. For Ground 1A (sale), courts expect to see estate agent instructions, solicitor letters, or marketing evidence. For Ground 1 (occupation), you need clear intention to move in yourself or immediate family.
12-month restrictions: After using Ground 1 or 1A, you cannot re-let the property for 12 months. Breach this and face penalties up to £7,000.
Longer notice periods: Budget for 4 months' notice instead of 2 for most grounds. Plan property management accordingly.
Court costs: With no guaranteed Section 21 win, budget for potential court hearing costs and legal fees for disputed Section 8 cases.
Defending Against Wrongful Evictions After 1 May 2026
Once Section 21 is abolished, any attempt to evict without proper Section 8 grounds becomes wrongful eviction — a serious matter that can lead to substantial compensation.
Common Wrongful Eviction Scenarios
- Invalid Section 21 notices served after 30 April 2026
- Landlord harassment designed to force you out without proper legal process
- False Section 8 grounds — e.g., claiming Ground 1A (sale) with no genuine intention to sell
- Procedural failures — incorrect notices, wrong notice periods, or missing legal requirements
- Deposit/registration breaches — landlords who haven't protected your deposit or registered on the PRS Database
Your Rights and Remedies
If your landlord tries wrongful eviction after May 2026:
- Stay put — you have the right to remain until a valid court order
- Document everything — keep records of harassment, invalid notices, or threats
- Report to the council — local authorities can issue civil penalties up to £7,000
- Claim compensation — wrongful eviction can result in substantial damages
- Rent repayment orders — reclaim up to 12 months' rent for serious breaches
Small Claims Court Territory
Most wrongful eviction claims fall within small claims court limits (under £10,000). This includes:
- Compensation for unlawful eviction
- Damages for harassment
- Additional accommodation costs
- Stress and inconvenience compensation
