Section 21 Replacement Notice: Renters Rights Act

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.

The human cost of that system was significant. Shelter recorded over 30,000 Section 21 notices issued between July 2024 and June 2025, with 11,400 households actually evicted via bailiff in the year after the government committed to banning the notices (Shelter, 2026). Many of those evictions followed tenants raising repair complaints or requesting improvements. The link between complaint and eviction was rarely coincidental.

The Renters' Rights Act 2025 ended that. From 1 May 2026, Section 21 notices no longer have legal force. Any notice served after that date is void. Any eviction attempt relying on one should be challenged immediately.

If your landlord served a Section 21 notice before 1 May 2026, there were transitional rules to consider. Notices had to be valid on their face, and landlords had to meet procedural requirements around deposit protection before they could rely on one. You can read more about the timing and your rights in our article on Section 21 ends on 1 May 2026. What that means for your tenancy.

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. Now Section 8 is the only option.

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 two months' rent arrears at the date of notice and at the date of hearing.
• Ground 1 (new version): the landlord genuinely intends to move in or sell the property.
• Ground 6: the landlord intends to redevelop the property.

Notice periods vary by ground. Ground 8 requires at least four weeks' notice, whereas grounds linked to landlord intention, such as moving in or selling, have their own specific notice requirements under the new rules.

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. Kennedys Law specifically flagged that meticulous compliance with procedural requirements is now essential to avoid invalidating possession claims (Kennedys Law, 2026).

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.

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 1 (intending to sell) as cover for kicking out a tenant who complained about mould. They can use Ground 1 if they genuinely intend to sell. 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.

The Renters' Rights Act abolished assured shorthold tenancies (ASTs) from 1 May 2026. If you had an AST before that date, it automatically converted to a new-style periodic tenancy on that date.

This matters for a few reasons. Fixed-term tenancies no longer exist in the traditional sense for private renters. You're now on a rolling periodic tenancy by default, which means there's no cliff-edge at the end of a 12-month contract where your landlord could previously serve a Section 21 notice.

The trade-off is that landlords can use new grounds to recover possession when their circumstances genuinely change. Ground 1 for selling and Ground 1A for moving in are both available after the tenancy has been running for a set period, with four months' notice required.

If you're unsure what type of tenancy you have, or whether the automatic conversion applies to you, Remedy Legal offers a free instant situation assessment. Share the key details and Remedy gives you a clear read on your legal position, without jargon or a costly consultation.

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 four 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.

5. Does your landlord have a valid licence? If your property is an HMO or falls within a selective licensing area, an unlicensed landlord faces restrictions on possession proceedings and may owe you a rent repayment order of up to 12 months' rent.

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.

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 housing law practitioners are clear that delays will increase.

Higgs LLP advised landlords to prepare thorough documentation and have their legal arguments in order before issuing proceedings, precisely because courts now require proof of every ground (Higgs LLP, 2026). 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.

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.
