Section 21 Abolished: What Landlords Need to Know

The abolition of Section 21 is the single biggest change to the private rented sector in a generation. No-fault evictions are gone, and landlords must now rely entirely on specific grounds to regain possession of their properties. This guide explains what has changed, what has replaced Section 21, and how landlords should adapt.

What Was Section 21?

Section 21 of the Housing Act 1988 allowed landlords to end an assured shorthold tenancy without giving a reason. It was commonly called a "no-fault" eviction because the landlord did not need to prove the tenant had done anything wrong. The landlord simply served a Section 21 notice giving two months' notice, waited for the notice period to expire, and if the tenant did not leave, applied to the court for a possession order.

In practice, Section 21 was the most commonly used route for landlords to regain possession. It was straightforward, predictable, and did not require evidence of tenant misconduct. Courts were required to grant possession once the notice had been validly served and the correct procedure followed.

However, Section 21 was not without restrictions even before abolition. Landlords could not serve a valid Section 21 notice unless they had protected the tenant's deposit and served prescribed information, provided the gas safety certificate, EICR, EPC, and How to Rent guide, and complied with any improvement notice or emergency remedial action notice from the local authority. These requirements often tripped up landlords who assumed Section 21 was a simple form to fill in.

Why Was Section 21 Abolished?

The government argued that no-fault evictions created insecurity for tenants. Renters could be asked to leave at any time, even when they had paid rent on time and looked after the property. Housing charities reported that fear of a Section 21 notice discouraged tenants from complaining about disrepair or poor conditions, because raising issues could prompt a retaliatory eviction.

While retaliatory eviction protections existed under the Deregulation Act 2015 (which prevented Section 21 notices being served within six months of a local authority serving an improvement notice), campaigners argued these protections were too narrow. The fundamental problem remained: a landlord could end a tenancy for no reason at all.

The Renters' Rights Act 2025 abolished Section 21 entirely. From the date the relevant provisions came into force, no new Section 21 notices could be served, and existing notices that had not yet resulted in a court order ceased to be valid.

What Replaces Section 21?

Section 8 of the Housing Act 1988 is now the only route for landlords to regain possession. Section 8 requires the landlord to specify one or more grounds for possession. The Renters' Rights Act has expanded and strengthened the available grounds to ensure landlords can still recover their properties when they have a legitimate reason to do so.

Our comprehensive guide to Section 8 eviction grounds explains each ground in detail. Below is a summary of the key grounds landlords are most likely to use.

Ground 1: Landlord Wishes to Occupy

You can regain possession if you (or a close family member) intend to live in the property as your only or principal home. You must give four months' notice. This ground is mandatory, meaning the court must grant possession if the ground is proven. However, you cannot use this ground within the first 12 months of the tenancy.

Ground 1A: Landlord Wishes to Sell

This is a new ground introduced by the Renters' Rights Act. You can seek possession if you intend to sell the property. You must give four months' notice, and the ground cannot be used within the first 12 months of the tenancy. This is mandatory. If you use this ground, you cannot re-let the property within 12 months of obtaining possession — if you do, the former tenant may be entitled to compensation.

Ground 6: Redevelopment

You can seek possession if you intend to demolish, reconstruct, or carry out substantial works to the property that cannot reasonably be done with the tenant in occupation. Four months' notice is required. This is mandatory but requires evidence of genuine planned works.

Ground 8: Serious Rent Arrears

If the tenant owes at least two months' rent (for monthly tenancies) both when you serve the notice and at the court hearing, the court must grant possession. This remains one of the strongest grounds available. Notice period: four weeks for monthly tenancies.

Grounds 10 and 11: Persistent Late Payment

These grounds cover tenants who are habitually late paying rent, even if they eventually pay. They are mandatory grounds but require clear evidence of a pattern of late payment over time.

Ground 14: Anti-Social Behaviour

This discretionary ground covers tenants (or their visitors) who cause nuisance or annoyance to neighbours or engage in criminal activity at or near the property. For the most serious cases, no notice period is required and the court can expedite proceedings.

Ground 14A: Domestic Abuse

A new ground allowing possession where one partner has been convicted of domestic abuse against the other. The tenancy can be ended to remove the perpetrator while allowing the victim to remain or be rehoused.

Notice Periods Under the New System

Notice periods vary depending on the ground used. The main notice periods are:

Four months: Ground 1 (landlord occupation), Ground 1A (sale), Ground 6 (redevelopment).
Four weeks: Ground 8 (serious rent arrears), Grounds 10 and 11 (persistent late payment).
Two weeks: Ground 14 (anti-social behaviour) in serious cases.
No notice required: Ground 14 where there is a risk of serious harm.
Two months: Various other grounds including Ground 12 (breach of tenancy) and Ground 13 (property deterioration).

All notices must be served using the correct prescribed form. An incorrectly served notice is invalid and will be thrown out by the court, meaning you have to start the process again.

The 12-Month Restriction

Several of the most important grounds — including Ground 1 (landlord occupation) and Ground 1A (sale) — cannot be used within the first 12 months of a tenancy. This is designed to give tenants a minimum period of security. If you know you may want to sell or move into the property within a year, you need to factor this restriction into your plans before granting the tenancy.

The 12-month restriction applies from the start of the tenancy with a particular tenant. If you grant a tenancy knowing you plan to sell within months, you will be locked in for a full year regardless.

Anti-Avoidance Measures

The Renters' Rights Act includes provisions to prevent landlords from misusing possession grounds. If you obtain possession using Ground 1A (intention to sell) but then re-let the property instead of selling it, the former tenant can seek compensation. Similarly, if you use Ground 1 (landlord occupation) but do not actually move in, you face potential penalties.

These provisions are enforced through local authorities and the courts. Landlords who abuse the system risk financial penalties and reputational damage. Courts can also take prior misuse into account when considering future possession claims.

What This Means Practically for Landlords

The shift from Section 21 to Section 8 has several practical consequences that every landlord needs to understand.

Documentation Is Now Critical

Under Section 21, landlords did not need to justify their decision. Under Section 8, every possession claim requires evidence. For rent arrears, you need clear rent payment records. For anti-social behaviour, you need dated incident logs and, ideally, reports from neighbours or the police. For property deterioration, you need photographic evidence from your inventory and subsequent inspections.

Equally, tenants can now defend against possession claims by arguing the landlord has not met their own legal obligations. If you cannot prove you provided the required documents at the right time, a tenant can use your non-compliance as a defence. This is why having the right evidence for tribunal is so important.

Longer Timelines

Section 21 possession claims were processed through the accelerated possession procedure, which was relatively quick and did not usually require a hearing. Section 8 claims go through the standard court process, which typically takes longer. You should expect the process from serving notice to obtaining an order to take several months, and potentially longer if the tenant contests the claim.

Building in this additional time is essential for planning. If you need to sell with vacant possession or move into the property, start the process well in advance.

Tenant Screening Matters More

When you could fall back on Section 21, a problematic tenancy could be ended relatively simply. That safety net no longer exists. Thorough referencing, credit checks, and previous landlord references are more important than ever. Taking the time to find reliable tenants upfront saves significant cost and stress later.

Compliance Must Be Watertight

Under the old system, compliance failures could invalidate a Section 21 notice, but a landlord could fix the issue and serve a new notice. Under the new system, compliance failures give tenants a defence against any possession ground. If you have not provided the required safety certificates, served the How to Rent guide, or protected the deposit correctly, you weaken your position in every possession scenario.

Our guide on what landlords must do under the Renters' Rights Act covers the full set of obligations.

Periodic Tenancies: The New Default

The Renters' Rights Act has also abolished fixed-term tenancies for new assured tenancies. All tenancies are now periodic from the start. Tenants can leave by giving two months' notice at any time. You cannot include a break clause or minimum term that prevents the tenant from leaving.

This changes the dynamic of the landlord-tenant relationship. Good tenants will stay if they are happy; poor conditions or unreasonable behaviour will prompt them to leave. Landlords who maintain their properties well and treat tenants fairly are likely to see less turnover than those who do not.

Preparing for Possession Claims

If you do need to seek possession, preparation is everything. Before serving a Section 8 notice:

Confirm you have provided all required documents and can prove delivery.
Check that the deposit is properly protected and prescribed information has been served.
Gather all evidence supporting the ground you intend to use.
Use the correct prescribed notice form.
Ensure you give the correct notice period for your chosen ground.
Keep records of how and when the notice was served.
Consider taking legal advice, particularly for discretionary grounds.

The court will scrutinise every step of the process. Technical errors in serving notice or gaps in your evidence can result in the claim being dismissed, costing you time and money.

Key Takeaways

The abolition of Section 21 is not the end of landlords' ability to manage their properties. The enhanced Section 8 grounds cover the legitimate reasons landlords need to regain possession: selling, moving in, dealing with rent arrears, tackling anti-social behaviour, and carrying out major works.

What has changed is the burden of proof. You must now demonstrate a valid reason and back it up with evidence. Compliance with your legal obligations is no longer just about avoiding fines — it directly affects your ability to recover your property when you need to.

Landlords who keep organised records, meet their document delivery obligations, and maintain their properties to the required standard will navigate the new system successfully. Those who rely on informal arrangements and poor record keeping will find the process far more difficult.
