Section 21 vs Section 8: What Changes for Landlords in 2026
Last updated:
Before 1 May 2026, landlords could use Section 21 (no reason needed, 2 months notice) or Section 8 (specific grounds). From 1 May 2026, Section 21 is abolished and Section 8 is the only route to possession. The key difference is that landlords must now have a legal reason to end a tenancy.
For 35 years, Section 21 of the Housing Act 1988 was one of the most debated provisions in English housing law. It allowed landlords to recover possession of their properties without giving any reason, simply by serving two months notice. Critics called it "no-fault eviction." Supporters called it a necessary tool for landlords to manage their assets. From 1 May 2026, it no longer exists.
The Renters' Rights Act 2025 (Royal Assent: 27 October 2025) abolishes Section 21 and reforms the Section 8 possession framework. Understanding what existed before and what applies now is essential for every landlord in England.
How Section 21 worked
Section 21 allowed landlords to serve a "no-fault" notice requiring a tenant to leave at the end of a fixed-term tenancy or at any time during a periodic tenancy, with two months notice and no obligation to give a reason.
Section 21 was introduced in the Housing Act 1988 alongside the Assured Shorthold Tenancy. The intention was to encourage private landlords to enter the market by providing a straightforward exit mechanism. Without Section 21, the theory went, landlords would be unwilling to rent their properties for fear of being unable to recover them.
How Section 21 worked in practice
To serve a valid Section 21 notice, a landlord needed to:
- Hold an Assured Shorthold Tenancy (almost all private residential tenancies were)
- Have the fixed term ended, or be in a periodic tenancy
- Have complied with all prescribed pre-tenancy obligations: deposit protected within 30 days and prescribed information served, EPC provided, How to Rent guide provided, gas safety certificate current and provided, EICR current
- Serve Form 6A (Section 21 notice) giving at least 2 months notice
- Issue court proceedings within the validity period if the tenant did not vacate voluntarily
Why Section 21 was controversial
Section 21 was criticised because:
- Tenants could be evicted for exercising legitimate rights (complaining about disrepair, for example) with no provable connection between complaint and eviction
- It contributed to housing insecurity, with tenants reluctant to make complaints or put down roots
- The notice period (2 months) was often insufficient for families with children in local schools to find alternative accommodation
- It created a significant power imbalance in an increasingly tight rental market
Landlord groups argued it was necessary to protect property rights and provide flexibility in portfolio management. The abolition reflects the government's view that the balance had tilted too far against tenants.
How Section 8 works now
Section 8 of the Housing Act 1988 allows landlords to seek possession based on specific grounds. From 1 May 2026, it is the only route to possession. The Renters' Rights Act 2025 amends Section 8 significantly, adding new grounds, strengthening some existing ones, and setting new notice periods.
Mandatory grounds (court must grant possession)
| Ground | Reason | Notice period | Restrictions |
|---|---|---|---|
| Ground 1 | Landlord or close family member requires property as principal home | 4 months | Not available in first 12 months of tenancy |
| Ground 1A | Landlord intends to sell the property | 4 months | Not available in first 12 months of tenancy |
| Ground 2 | Mortgagee in possession | 2 months | Specific mortgage conditions apply |
| Ground 7A | Serious antisocial behaviour conviction | No minimum | Criminal conviction required |
| Ground 8 | Rent arrears of 2 months (or 8 weeks for weekly rent) at notice and at hearing | 2 weeks | Arrears must exist at both notice and hearing |
Discretionary grounds (court may grant possession)
| Ground | Reason | Notice period |
|---|---|---|
| Ground 10 | Some rent arrears (below Ground 8 threshold) | 2 weeks |
| Ground 11 | Persistent late payment of rent (even if not currently in arrears) | 2 weeks |
| Ground 12 | Breach of any tenancy obligation (other than rent) | 2 weeks |
| Ground 13 | Deterioration of the property due to tenant neglect | 2 weeks |
| Ground 14 | Nuisance or annoyance to neighbours, or conviction for illegal/immoral use of property | No minimum |
| Ground 17 | False statement made by tenant to obtain the tenancy | 2 weeks |
The new Ground 1A: selling the property
Ground 1A is a new ground introduced specifically by the Renters' Rights Act 2025 to address landlords who want to sell. It is mandatory (court must grant possession if proven) but has two key restrictions: it cannot be used within the first 12 months of a tenancy, and the landlord must genuinely intend to sell. The 4-month notice period means that a landlord who decides to sell will typically not obtain vacant possession for 6-10 months from that decision.
Side-by-side comparison: Section 21 vs Section 8
| Feature | Section 21 (abolished 1 May 2026) | Section 8 (only route from 1 May 2026) |
|---|---|---|
| Reason required? | No. No reason needed. | Yes. Must rely on a specific statutory ground. |
| Court required? | Only if tenant did not vacate voluntarily | Always required if tenant does not vacate voluntarily |
| Notice period | Minimum 2 months | 2 weeks to 4 months depending on ground |
| Can tenant contest? | Only on procedural grounds | Yes, tenant can contest whether the ground is proven |
| Fastest timeline if contested | 4-6 months from notice to possession | Ground 8: 3-5 months; Grounds 1/1A: 6-10 months |
| Available for selling? | Yes (any reason) | Yes (Ground 1A, after 12 months, 4 months notice) |
| Available to move in? | Yes (any reason) | Yes (Ground 1, after 12 months, 4 months notice) |
| Evidence required? | Minimal (procedural compliance only) | Evidence of the ground required at court |
| Court hearing | Accelerated possession procedure possible (no hearing) | Hearing required in most cases |
| Mandatory outcome? | Yes (if procedurally valid) | Only for mandatory grounds (Grounds 1, 1A, 2, 7A, 8) |
| Cost to landlord | Court fee (~£355) + enforcement costs if needed | Court fee + potentially higher legal costs for contested hearings |
What is harder under Section 8 compared to Section 21?
Recovering possession for the purpose of selling or moving in is significantly harder under Section 8 than Section 21 was. You must wait 12 months, give 4 months notice, and go through court. For rent arrears, Section 8 Ground 8 is effective if properly prepared.
Scenarios where Section 8 is more difficult
Selling the property
Under Section 21, a landlord could serve 2 months notice at any point in a periodic tenancy. Under Section 8 Ground 1A, the landlord must wait until the tenancy is at least 12 months old, give 4 months notice, go to court if the tenant does not vacate voluntarily, and prove genuine intention to sell. The total timeline from decision to sell to vacant possession is typically 6-12 months, compared to 3-5 months under Section 21.
Moving back into the property
The same analysis applies to Ground 1. A landlord who could previously serve Section 21 and move in after 2 months now needs to wait 12 months into the tenancy and give 4 months notice.
Redevelopment and major works
Ground 6 (landlord requires possession for redevelopment) remains available but is discretionary and requires proof of genuine redevelopment intention. It cannot be used if the landlord created the need for redevelopment themselves.
Scenarios where Section 8 is comparable or easier
Rent arrears
Ground 8 (2 months arrears) is mandatory and requires only 2 weeks notice. If a tenant is in 2 months arrears at the time the notice is served and at the time of the court hearing, possession is mandatory. Good landlords who document arrears carefully are not significantly disadvantaged for this scenario.
Antisocial behaviour
Ground 14 (antisocial behaviour) has no minimum notice period and courts can grant immediate possession if the behaviour is serious. This is faster than Section 21 was in extreme cases.
What is similar between the old and new system?
The basic court process for possession is similar under both systems. The prerequisites for a valid notice (deposit protection, EPC, How to Rent, gas safety) apply to Section 8 as they did to Section 21.
To serve a valid Section 8 notice, the same compliance prerequisites remain important:
- Deposit must be protected in an approved scheme within 30 days of receipt
- Prescribed information about the deposit must have been served
- EPC must have been provided before the tenancy started
- Current gas safety certificate must have been provided
- EICR (Electrical Installation Condition Report) must be current
- How to Rent guide must have been provided
The court process for Section 8
- Serve a valid Section 8 notice in the prescribed form (Form 3), specifying the ground(s) and the date after which proceedings may be issued
- Wait for the notice period to expire
- If the tenant does not vacate, issue a possession claim at the county court
- Attend the hearing for contested cases
- If possession is granted, the court specifies a date by which the tenant must leave
- If the tenant does not comply with the possession order, apply for a warrant of possession (bailiff enforcement)
Strategic advice for landlords adapting to the new system
Invest in record-keeping from day one
The quality of your records is the most important factor in Section 8 success. Start keeping the following from the moment a tenancy begins:
- A comprehensive signed inventory with photographs
- A rent ledger showing every payment received, missed, or late
- Written records of all communications with the tenant
- Copies of all notices served and evidence of service
- Records of all inspections with photographs
- Records of any neighbour complaints about the tenant
Act early on arrears
Under the Section 21 system, many landlords tolerated small or occasional arrears because they could ultimately serve Section 21 regardless. Under Section 8, you need arrears to reach the Ground 8 threshold (2 months) for mandatory possession. Act swiftly: contact the tenant in writing within 48 hours of a missed payment, follow up with a formal letter if not resolved within 7 days, and serve Section 8 on Grounds 10 and 11 once arrears reach 1 month.
Plan ahead for selling or moving in
The 12-month waiting period and 4-month notice for Grounds 1 and 1A mean you need to plan significantly further ahead. If you think you may want to sell in the next 2-3 years, note the tenancy start date and when Ground 1A becomes available (12 months from start). Consider whether selling with the tenant in situ (to a buy-to-let investor) might be faster than seeking vacant possession.
Consider rent guarantee insurance
With Section 8 proceedings taking longer than Section 21 did for non-arrears cases, rent guarantee insurance becomes more valuable. Look for policies that cover arrears from the first missed payment, include legal costs for Section 8 proceedings, and provide cover for 12-18 months to account for longer possession timelines.
Get compliant and stay compliant
The compliance prerequisites for serving notice remain essential. Courts take compliance seriously and a pattern of non-compliance weakens your overall position. Stay on top of all renewal dates for certificates and documents. LandlordOS tracks all compliance deadlines and sends reminders before certificates expire.
What landlords with outstanding Section 21 notices should do now
If you have a valid Section 21 notice outstanding before 1 May 2026, act promptly. The notice remains valid after the abolition date, but you must issue court proceedings within the validity window. After 1 May 2026, no new Section 21 notices can be served.
If you have served a Section 21 notice and the tenant has not vacated
- Check the date your Section 21 notice (Form 6A) was served and the notice period it gave
- Calculate the end of the validity period (typically 6 months from the end of the notice period)
- If still within the validity period, issue possession proceedings at the county court promptly
- If the validity period has expired, you cannot use that notice and must use Section 8 grounds from 1 May 2026 onwards
If you are considering serving Section 21 before 1 May 2026
You can still serve a Section 21 notice before 1 May 2026 if all compliance prerequisites are met: deposit protected, prescribed information served, valid EPC, current gas safety certificate, EICR current, and How to Rent guide provided. A notice served before 1 May 2026 remains valid and can be enforced through the courts even after the abolition date. If you have a situation where Section 21 is appropriate and you can meet all requirements, acting before 1 May 2026 may give you more options.

Frequently asked questions about Section 21 vs Section 8
Is Section 8 harder than Section 21 was?
For rent arrears cases, Section 8 with Ground 8 (2 months arrears) is straightforward — possession is mandatory if the ground is proven. For cases where you want the property back to sell or move in, Section 8 is harder: you must wait 12 months, give 4 months notice, and go through court. Section 21 required only 2 months notice with no reason and no court if the tenant complied.
How long does Section 8 take compared to Section 21?
Section 21 typically took 4-6 months from notice to possession if contested; often less if the tenant left voluntarily. Section 8 for arrears (Ground 8) takes about 3-5 months. Section 8 for selling or moving in (Grounds 1/1A) takes 6-10 months due to the 4-month notice and potential court proceedings. Section 8 is generally slower than Section 21 was for non-arrears possession.
Do I need a reason to evict a tenant now?
Yes. From 1 May 2026, landlords must have a recognised legal ground under Section 8 and prove it at court if contested. The grounds cover the most common situations (arrears, breach, selling, moving in), but there is no equivalent of Section 21's no-reason provision. Good tenants who pay rent on time and do not breach their agreement have significantly greater security of tenure.
What if I served a Section 21 before 1 May 2026?
A valid Section 21 notice served before 1 May 2026 remains legally effective. You can issue court proceedings based on it even after the abolition date, provided the notice has not expired. Act promptly — Section 21 notices typically expire 6 months after the end of the notice period. If yours is nearing expiry, issue proceedings now rather than waiting.
Can I start eviction proceedings with a Section 21 notice served before the deadline?
Yes. The government has confirmed that pre-abolition Section 21 notices can still be enforced through the courts. Possession orders obtained from valid pre-abolition Section 21 notices will be executed. You must issue proceedings within the validity window of the notice.
What is the fastest Section 8 ground to use?
Ground 14 (antisocial behaviour) and Ground 7A (serious criminal conviction) have no minimum notice period. Ground 8 (2 months rent arrears) requires 2 weeks notice and is mandatory, making it the fastest route for arrears cases. Grounds 1 or 1A (selling/moving in) require 4 months notice and are not available in the first 12 months of a tenancy.
LandlordOS tip
The single best thing you can do to prepare for the Section 8 regime is to have a complete, signed, and photographed inventory for every tenancy, with evidence that it was served on the tenant. The inventory is the foundation of any claim for damage, and documented service of required documents is critical to a valid possession case. If you do not currently use a professional inventory service, start now. If you manage it yourself, ensure every page is initialled by the tenant and the complete inventory is emailed to them with an acknowledgement request.
