Section 21 vs Section 8: what UK landlords need to know in 2026

Under Section 21 of the Housing Act 1988, a landlord can recover possession at the end of a fixed-term assured shorthold tenancy without proving fault. Two months' notice in writing. No reason required. The court must grant possession provided procedural requirements have been met (deposit protection, EPC served, How to Rent guide served, valid Gas Safety certificate, etc.).

Section 21 has been the workhorse of private-sector eviction in England since 1988. The Renters' Rights Bill abolishes it. From a date yet to be fixed (likely within 12 months of Royal Assent), landlords will no longer be able to serve a Section 21.

Notices already served before the cut-off will remain valid for their original two-month period, but the limited window will be tight. If you have a possession decision to make in the next 6-12 months, do it before the transition window.

Section 8 of the Housing Act 1988 lets a landlord recover possession by citing a specific ground from Schedule 2. Grounds are split into mandatory (court must grant possession if proved) and discretionary (court can refuse if not reasonable).

Current mandatory grounds most landlords use: ground 8 (eight weeks of rent arrears at the date of service and at the date of hearing), ground 1 (landlord requires the property as their main residence), grounds 2-7 (mortgage repossession, holiday let return, demolition, etc.).

Current discretionary grounds most landlords use: ground 10 (any arrears), ground 11 (persistent late payment), ground 12 (breach of any tenancy clause), grounds 13-17 (deterioration, nuisance, false statement on application, etc.).

Once the Bill commences, the only route to possession is the reformed Section 8. The grounds are expanded and reorganised. Key changes:

**New mandatory ground for sale.** Landlord must own the property for at least 12 months and not have served a sale-ground notice in the previous 12 months. Notice period: 4 months. Tenant must be in occupation for at least 12 months.

**New mandatory ground for landlord or family occupation.** Same 12-month ownership rule. 4-month notice. Family members covered include landlord, spouse, parents, children and grandchildren.

**Tighter rent-arrears ground.** Mandatory possession requires three months of rent arrears at both service and hearing (was two months). Notice period extended.

**Anti-social behaviour ground accelerated.** Court can hear an ASB-ground possession case faster.

**Persistent rent arrears ground retained.** Three months' arrears in three of the previous twelve months is sufficient.

**Tenancies started before the cut-off.** All convert to statutory periodic tenancies on the date the Bill commences. Existing fixed-term clauses fall away. The tenant gains the right to give two months' notice at any time.

**Selling a let property.** Becomes possible only after 12 months of ownership and only by serving the new sale-ground Section 8. Plan disposal timing accordingly.

**Buying tenanted stock.** The 12-month new-ownership clock resets on completion. Buyers cannot serve possession notices for at least a year.

**Rent arrears strategy.** The bar moves to three months from two. Earlier engagement with tenants on arrears is more important — once they hit two months you used to have a hard deadline; now you have a longer runway but a slower court path.

**Court backlog.** The reform comes alongside an already-stretched court system. Realistic time from Section 8 service to bailiff is likely to extend to 8-14 months for contested cases.

**If you have a tenancy you want to end in the next 6 months**: serve a clean Section 21 now, while it remains valid. The two-month notice runs, and the court window remains open under transitional provisions.

**If you have rent arrears building**: don't wait for the new three-month threshold. Open dialogue with the tenant as soon as arrears exceed one month. Mediation through a service like [Citizens Advice or Shelter](https://www.gov.uk/private-renting-evictions) is cheaper and faster than court.

**If you have property you intend to sell**: complete the sale before the Bill commences if at all possible. The 12-month new-ownership rule makes flip-buying significantly slower.

**Update your tenancy agreements**: most existing tenancy templates reference the assured shorthold framework. After commencement, those clauses largely become inoperative. A clean refresh via your solicitor or your letting agent is worth the £100 or so it costs.

Discretionary grounds 10 through 17 will still exist post-reform. They are slower and the court can refuse possession if it thinks the breach is minor, but they remain a route. For chronic late payment, partial arrears, or persistent breach, ground 11 and ground 12 are still your best route.
