The Fundamental Difference
Section 21 allowed landlords to recover possession at the end of a fixed term tenancy without giving a reason. It required no ground, no allegation against the tenant, and no court hearing if the tenant vacated — just the notice and, if contested, a generally straightforward court process.
Section 8 requires the landlord to prove a specific statutory ground for possession — typically rent arrears, breach of tenancy, or one of the new grounds introduced by the Renters' Rights Act 2025 such as Ground 1A (selling). The tenant can contest the claim on the merits, the ground must be proven at a court hearing, and the court has discretion on many grounds.
This is a more process-heavy route — but for landlords who maintain compliant tenancies, it is not as difficult as headlines have suggested.
Side-by-Side Comparison
| Aspect | Section 21 (abolished) | Section 8 (current) |
|---|---|---|
| Reason required? | No — no-fault | Yes — must prove a statutory ground |
| Notice period | 2 months | 0–4 months depending on ground |
| Court hearing required? | No (if tenant vacates) | Always — even if uncontested |
| Compliance requirements | All docs must be in order | All docs must be in order |
| Tenant can contest? | On compliance only | On ground AND compliance |
| Timeline (uncontested) | 8–12 weeks | 16–24 weeks |
| Still available? | No — abolished 1 May 2026 | Yes — only route to possession |
What Stayed the Same
The compliance pre-conditions are virtually identical. Under Section 21, a landlord could not serve a valid notice without first having served: a valid Gas Safety Certificate, a valid EICR, the current How to Rent guide, and deposit prescribed information. Under Section 8, all of these same documents must be in order and evidenced before serving any notice.
In this sense, the Renters' Rights Act has not changed the compliance burden — it has simply made it more visibly consequential. A landlord who maintained compliant tenancies under the old regime faces a largely familiar compliance landscape under the new one.
What Actually Changed for Landlords
The practical difference is that Section 8 always requires a court hearing — even for an uncontested claim where the tenant has already moved out. Under Section 21, if the tenant vacated before the hearing, the landlord simply didn't attend and had their property back without any court involvement. Under Section 8, a possession order is always required, which means a court fee, paperwork, and a hearing date.
The other significant change is that the ground must be proven. Ground 8 (serious rent arrears) is mandatory — if arrears are 3 months or more at the notice and hearing dates, the court must grant possession. But discretionary grounds require the court to be satisfied that it is reasonable to grant possession, which introduces uncertainty that Section 21 never had.
