Opening a letter from your landlord that says they want you out is never a good morning. For years, that letter might have been a Section 21 notice, and the law gave you almost no way to fight it. That changed on 1 May 2026.
The Renters' Rights Act 2025 ended new Section 21 notices for private assured tenancies in England. Landlords need a specific legal ground for a new possession claim. If you rent in England, it pays to understand what replaced Section 21.
The short version: Section 8 is the route for new possession claims, while Section 21 applications made in time can still proceed. Section 8 has rules, grounds and notice periods that landlords must follow. Here is what the Section 21 replacement notice looks like under the Renters' Rights Act, what grounds landlords can now use, and what to do if you receive one.
What a Section 21 notice was and why it's gone
Section 21 of the Housing Act 1988 let landlords evict tenants without giving any reason. The legal term was a 'no-fault eviction'. A landlord could decide they wanted their property back, serve a two-month notice, and the court would rubber-stamp the possession order.
Tens of thousands of these notices were served every year, and many followed tenants raising repair complaints or requesting improvements. The link between complaint and eviction was rarely coincidental.
The Renters' Rights Act 2025 ended new Section 21 notices for these tenancies from 1 May 2026. A notice served on or after that date cannot support a Section 21 claim.
For a Section 21 notice served before 1 May 2026, the landlord had to apply to court before the notice's time limit expired and no later than 31 July 2026. An application made in time can still proceed, and the notice's validity can still be challenged. Our guide explains what Section 21 ending means for your tenancy.
How Section 8 notices work now that Section 21 is gone
Section 8 of the Housing Act 1988 has always existed, but it was secondary to Section 21 because landlords preferred the simpler no-fault route. Section 8 is now the route for new possession claims involving these tenancies.
A Section 8 notice requires a landlord to cite at least one specific ground for possession. Each ground is numbered and has its own rules. Some grounds are mandatory, meaning the court must grant possession if the ground is proven. Others are discretionary, meaning the court weighs the circumstances.
The most commonly used mandatory grounds after the Renters' Rights Act are:
- Ground 8: at least 3 months' rent arrears (13 weeks if you pay weekly or fortnightly), both at the date of notice and at the date of hearing. Arrears caused by an unpaid Universal Credit award you're entitled to don't count towards the threshold.
- Ground 1: the landlord or a close family member genuinely intends to move in.
- Ground 1A: the landlord genuinely intends to sell the property.
- Ground 6: the landlord intends to redevelop the property.
Notice periods vary by ground. Ground 8 requires at least 4 weeks' notice, while Grounds 1 and 1A require 4 months' notice and cannot be used at all in the first 12 months of your tenancy.
The procedural requirements are strict. If a landlord serves a Section 8 notice and gets the notice period wrong, cites the wrong ground, or hasn't protected the deposit correctly, the notice can be challenged.
If you've received a Section 8 notice, check the ground cited, check the notice period given, and check whether your deposit is properly protected. All three matter. Our guide to Section 8 Notice Grounds, Rights and How to Respond covers each ground in detail.
Can a landlord evict you for raising a repair complaint after May 2026?
This was the defining abuse of Section 21 and the Act directly addresses it.
The Renters' Rights Act 2025 introduced protections against what are called 'backdoor evictions'. If a landlord tries to evict you using a legitimate ground shortly after you raised a repair complaint, requested a rent reduction, or exercised a legal right, courts can take that context into account. The Act gives tenants a clear route to argue that the possession claim is retaliatory.
Put plainly, a landlord cannot use Section 8, Ground 1A (intending to sell) as cover for kicking out a tenant who complained about mould. They can use Ground 1A if they genuinely intend to sell, but serving that notice starts a restricted period. It runs from the day of service until 12 months after the date the notice gives as the earliest date for starting court proceedings, whether or not the landlord gets possession. Re-letting or re-marketing the property during that period is an offence carrying a civil penalty of up to £40,000 or prosecution, and you can apply to the First-tier Tribunal for a rent repayment order of up to 2 years' rent. The court can look at the timeline and assess whether the intention is real.
This doesn't mean challenging a Section 8 notice is automatic or simple. You will need evidence. Keep records of every repair complaint, every message, every response or non-response from your landlord. Date everything. If you reported damp in January and received a possession notice in February, that sequence tells a story.

What tenancy type do you have now under the Renters' Rights Act?
Most private assured shorthold tenancies in England converted to assured periodic tenancies on 1 May 2026. Conversion was delayed for qualifying transitional cases, including Section 21 applications made in time. If an older case is continuing, check which rules apply before assuming your tenancy has converted.
For a tenancy that has converted, the old fixed end date no longer ends the tenancy. It continues on a rolling basis, and the landlord needs a legal ground to seek possession.
The trade-off is that landlords can use new grounds to recover possession when their circumstances genuinely change. Ground 1 for moving in and Ground 1A for selling both become available once the tenancy has been running for 12 months, with 4 months' notice required.

How to challenge an invalid possession notice in 2026
Not every Section 8 notice is valid. Landlords are still learning the new system, and mistakes are common. Here's what to check:
1. Is the notice on the correct form? Section 8 notices must use the prescribed form. A letter saying 'we want you to leave' is not a valid Section 8 notice.
2. Is the ground correctly stated? The notice must specify which statutory ground is being relied on. If the landlord ticks the wrong box or cites a ground that doesn't apply to your situation, the notice is defective.
3. Is the notice period correct? Each ground has a minimum notice period. Ground 8 arrears requires at least 28 days. Grounds based on the landlord wanting to sell or move in require 4 months. A notice with the wrong period is invalid.
4. Is your deposit protected? If your deposit was not protected in a government-approved scheme within 30 days of payment, your landlord may be barred from relying on certain grounds and you may have a separate compensation claim. You can read more about Deposit Protection Violations: Claim Compensation.
If any of these fail, the notice can be challenged. Don't move out without checking first. Write to your landlord citing the specific defect and keep a copy of everything. Remedy Legal's letter drafting tool helps you produce a formal letter citing the relevant legislation, which is often enough to make a landlord rethink their position.
A missing licence is not on this list, because it no longer makes a notice invalid. An unlicensed HMO or selective-licensing property once blocked a Section 21 notice, but those bars were repealed on 1 May 2026 and do not stop a Section 8 claim. It is still worth acting on. Your landlord risks a civil penalty or prosecution, and you can apply for a rent repayment order of up to 2 years' rent for offences committed on or after 1 May 2026.
What courts expect from landlords bringing possession claims in 2026
The abolition of Section 21 was always going to increase the volume of Section 8 possession claims going through court. Courts were already under pressure before May 2026, and delays are expected to grow.
Every Section 8 claim now needs a hearing, and the landlord has to prove the ground they cited with proper evidence. For tenants, that scrutiny works in your favour. A Section 8 claim that lacks evidence for the stated ground should not succeed.
If you end up at a possession hearing, you are entitled to present your case. That means bringing evidence that contradicts the landlord's ground, evidence of retaliation, or evidence that the notice was procedurally defective. You do not need to be legally represented to attend, though having a clear argument in writing helps considerably.
Remedy Legal's tribunal bundle generation tool helps tenants upload and annotate evidence, track deadlines, and produce a submission bundle for hearings. The platform also provides deadline tracking so nothing gets missed in the weeks before a hearing date.
What happens if your landlord tries an illegal eviction
Some landlords, faced with the end of Section 21 and the requirements of Section 8, will try shortcuts. Changing the locks. Removing belongings. Cutting off utilities. These are illegal eviction tactics and they were illegal before May 2026 too, but the Renters' Rights Act tightened the consequences.
Illegal eviction is a criminal offence under the Protection from Eviction Act 1977. You can report it to your local council, which has enforcement powers. You can also claim civil compensation through the courts.
If your landlord is pressuring you to leave without a valid notice, failing to make repairs to force you out, or interfering with your quiet enjoyment, that is harassment. The Renters' Rights Act added new protections here. You have grounds to claim compensation and, depending on the behaviour, to stay in the property.
For a full breakdown of what counts and what remedies are available, see our guides on Illegal Eviction Compensation UK: Rights and Remedies and What counts as landlord harassment and how to stop it.
The Section 21 replacement under the Renters' Rights Act is Section 8, and it is a better system for tenants. Landlords now have to prove their case, follow the right procedure, and give proper notice. If they don't, the notice fails.
But 'better system' doesn't mean automatic protection. You still need to check the notice you've received, understand the ground cited, and know whether your landlord has protected your deposit properly.
