Section 21 Abolition UK — What Landlords Need to Know

UK Landlord Daily · Updated March 2026 · 11 min read · This is general guidance, not legal advice. Consult a solicitor for your specific situation.

Section 21 — the "no-fault eviction" notice that allowed landlords to reclaim their property from tenants without giving a reason — has been abolished under the Renters Rights Act 2025. This is the most significant change to the private rented sector in England in decades, and it affects every private landlord.

This guide explains what Section 21 abolition means in practice, what now replaces it, and the specific steps landlords should take to protect their position under the new rules.

Important: This guide provides general educational information. The Renters Rights Act introduced detailed transitional provisions that depend on when your tenancy was created and whether any possession proceedings were already underway. Get specific legal advice for your situation.

What Was Section 21?

Section 21 of the Housing Act 1988 allowed landlords in England to serve a two-month notice on a tenant without needing to give any reason, provided the correct procedure was followed and the tenancy was out of its fixed term (or the fixed term had ended). If the tenant did not leave, the landlord could apply to court for a possession order, and — in theory — courts would grant it without needing to examine the reason for eviction.

It was called "no-fault" because the landlord did not need to demonstrate the tenant had done anything wrong. This gave landlords flexibility, but was criticised for leaving tenants in insecure housing, particularly in high-rent areas where they had limited alternatives.

What Replaces Section 21?

Section 21 has been replaced by a strengthened Section 8 possession system. Section 8 has always existed — it allows landlords to evict tenants who have breached their tenancy agreement, primarily for rent arrears or anti-social behaviour. Under the new rules, Section 8 grounds have been expanded to cover the main legitimate reasons landlords previously used Section 21.

Key New Section 8 Grounds

  • Landlord or family member moving in: New mandatory ground. A minimum tenancy protection period applies before this can be used. You cannot re-let within a set period after using this ground.
  • Genuine intention to sell: New mandatory ground. The property must be genuinely for sale and you cannot re-let within a set period.
  • Rent arrears: Existing mandatory ground, retained. Two months (or 8 weeks for weekly tenancies) arrears at the time of notice and at the court hearing.
  • Anti-social behaviour: Existing ground, retained and strengthened. Covers behaviour affecting neighbours and the community, not just the property.
  • Repeated late rent payment: New ground. Tenants who repeatedly pay late (even if they are never two months in arrears) can now be given notice.
  • Breach of tenancy agreement: Existing ground, retained. Covers unauthorised subletting, keeping pets in breach of the agreement, and similar.

The National Landlord Register

The Renters Rights Act created a mandatory national landlord register. Every private landlord in England must register their properties, providing addresses, contact details and relevant safety certification. Failure to register:

  • Results in significant financial penalties
  • Prevents you from using the new Section 8 grounds including the "sell" and "move in" grounds
  • Is enforceable by local councils

Registration opened in phases through 2025. Check gov.uk for the current status and register immediately if you have not done so.

The Property Ombudsman and Dispute Resolution

Alongside the court system, the new regime introduces a mandatory Property Ombudsman scheme. All landlords must be members. The ombudsman handles disputes about:

  • Repairs and maintenance
  • Rent increases challenged by tenants
  • Deposit disputes (in addition to existing Tenancy Deposit Scheme rules)
  • General tenancy conditions

Tenants must attempt ombudsman resolution before going to court for most issues. This is designed to reduce the court burden but adds a step to the dispute process.

Rent Increase Rules

Under the new rules, landlords can only increase rent once per year. The process:

  1. Serve a Section 13 notice with at least two months' notice of the proposed increase
  2. The increase cannot be above market rent
  3. Tenants can challenge any increase at the First-tier Tribunal if they believe it is above local market rate
  4. The tribunal will set the rent — which cannot be above market rate but also cannot be set below the landlord's existing rent

What Landlords Should Do Now

1. Register on the national landlord database

This is not optional. Register all properties. Without registration you cannot use the critical new Section 8 grounds.

2. Ensure all safety certificates are current

  • Gas Safety Certificate: annual requirement, must be provided to tenants
  • Electrical Installation Condition Report (EICR): every 5 years
  • EPC: minimum Band E required (Band C target on the horizon — start planning)
  • Smoke and CO alarms: required in all rooms with solid fuel burning appliances, smoke alarms on each floor

3. Switch to the new assured tenancy agreement format

All new tenancies must use the updated tenancy agreement format that complies with the Renters Rights Act. Using an old template creates compliance risk. Your letting agent or the NRLA (National Residential Landlords Association) can provide compliant templates.

4. Keep meticulous records

Under Section 8, the burden is on you to demonstrate the legal grounds for possession to the court. Keep:

  • Complete rent payment records with dates and amounts
  • All written communications with tenants
  • Records of repair requests and responses
  • Inspection logs
  • Copies of all notices served and their service dates

5. Consider specialist landlord legal insurance

Legal expenses insurance for landlords covers the cost of possession proceedings, rent arrears recovery and associated legal costs. Given the potential complexity of the new Section 8 process, this has become more valuable than under the old Section 21 regime where costs were more predictable.

6. Join the NRLA

The National Residential Landlords Association provides model tenancy agreements, legal helplines, compliance guidance and lobbying on landlord interests. Membership is a practical necessity for most landlords navigating the new rules.

Frequently Asked Questions

When is Section 21 being abolished?

Section 21 no-fault evictions were abolished under the Renters Rights Act 2025. The Act applies to new tenancies immediately and there were transitional provisions for existing tenancies. Check gov.uk for the latest implementation details.

What replaces Section 21 for landlords?

Strengthened Section 8 grounds, including new mandatory grounds for selling the property and the landlord or family moving in. Rent arrears and anti-social behaviour grounds remain, plus a new ground for repeated late payment.

Can landlords still sell a property with tenants?

Yes — there is a new Section 8 ground for genuine sale. A minimum tenancy protection period applies before this ground can be used and you cannot re-let within a set period after using it.

Do I need to register as a landlord?

Yes. All private landlords in England must register on the new national landlord database. Failure to register results in penalties and prevents use of key Section 8 grounds.

Can tenants still be evicted for rent arrears?

Yes. Two months arrears is a mandatory Section 8 ground — courts must grant possession if the arrears condition is met at both notice and hearing. Keep clear rent records and act early when arrears begin to accumulate.

Should landlords sell up after Section 21 abolition?

This depends on your personal circumstances, tax position, local market and portfolio size. The new rules add compliance complexity and reduce flexibility. Many landlords remain profitable — but the importance of tenant selection and thorough record-keeping has increased significantly.
