If you’re a landlord, tenant, or letting agent, “notice” is where most possession plans either succeed or fall apart. Get the date wrong, use the wrong form, or rely on the wrong ground, and you can lose weeks (sometimes months) before you’re back on track. With Section 21 abolition now confirmed to start on 1 May 2026, getting your notice strategy straight is no longer optional.
This guide walks you through what notice periods look like right now (before 1 May 2026), what changes from 1 May 2026, and how to plan so you’re not caught out.
If you want a wider overview of the reforms and the practical steps to take, you can also browse Atalaw’s own updates in the Resources section.
What “notice period” actually means (and why it’s misunderstood)
A notice period is not the date a tenant must leave by in real life. It’s the minimum time you must give before you’re allowed to start court proceedings (or, for tenants, before your tenancy can end by notice).
That difference matters because court timelines are already slow. Ministry of Justice stats show the median time from claim to repossession for landlord cases was 27.4 weeks (July–September 2025) — and that’s after the notice stage.
So if you’re building a timeline for a sale, refinance, move-in, or arrears recovery, notice is only the first leg of the race.
Today’s position (before 1 May 2026): Section 21 and Section 8 run in parallel
Section 21 (no-fault): the headline time limit
Right now, a standard Section 21 route typically starts with 2 months’ notice.
But it’s not just about the 2 months. You also have to keep an eye on strict “use-by” deadlines for issuing the court claim once the notice is served (and those deadlines become even more important during transition).
For a practical reform-focused explanation, see Atalaw’s UK-focused primer on where Section 21 stands now and how to plan for what’s next.
Section 8 (fault / grounds-based): notice varies by ground
Section 8 already exists today, but the notice period depends on which ground you’re using.
A few common examples before 1 May 2026:
- Rent arrears (Grounds 8, 10, 11): often 2 weeks’ notice
- Anti-social behaviour / nuisance (Ground 14): you can apply immediately (no minimum notice period)
- Owner-occupier / mortgage-related grounds: often 2 months’ notice
This is why “Section 8” isn’t one single timeline — you need a ground-by-ground approach.
If you’re dealing with possession and tenancy disputes generally, Atalaw’s Landlord And Tenant page is a helpful starting point.
Tenant notice today
If you’re a tenant on a rolling (periodic) tenancy, you can often end the tenancy with around 1 month’s notice (but it must be correctly timed).
From 1 May 2026: what changes under the reformed regime
The Government confirmed the key shift: Section 21 ends and the new tenancy regime starts on 1 May 2026.
From that point, the “default plan” changes:
1) Section 21 goes — notice planning becomes Section 8 planning
Once abolition begins, no new Section 21 notices can be served, and landlords will rely on grounds-based possession instead.
So the big practical shift is: you move from “serve notice + paperwork compliance” to “serve notice + evidence + ground selection + paperwork compliance”.
Atalaw’s explainer on Strengthened Section 8 grounds: arrears, ASB, and sale/occupation – what’s changing? is worth reading if you want the plain-English overview.
2) Notice periods change for key landlord grounds
Under the post-reform guidance, some of the most-used notice periods look like this:
- Serious rent arrears (Ground 8): 4 weeks’ notice
- Any arrears / persistent arrears (Grounds 10 and 11): 4 weeks’ notice
- Breach of tenancy (Ground 12) and property deterioration (Ground 13): 2 weeks’ notice
- Nuisance / anti-social behaviour (Ground 14): you can apply straight away, but the court can’t make a possession order for 14 days from the notice date
- Some “landlord needs the property back” routes (for example, sale/occupation style grounds): often 4 months’ notice
The reform effect is simple: for many scenarios, you should expect longer notice than you’ve been used to, unless the behaviour is serious enough to trigger faster routes.
3) “Protected periods” and guardrails affect when you can even use certain grounds
It’s not only the length of notice. The reforms also introduce timing restrictions designed to prevent misuse — for example, a 12-month protected period is expected for certain sale/occupation routes.
That means your “exit plan” for a property may need to start earlier than it currently does.
4) Tenant notice becomes more flexible, but longer
Post-reform, tenants will generally be able to end the tenancy with 2 months’ notice.
If you’re a landlord, that affects cashflow forecasting and void planning. If you’re a tenant, it affects how quickly you can move if you need to.

Transition planning: what to do between now and the reform start
Here’s the practical checklist most people overlook:
Diary critical dates (and don’t leave them to “memory”)
If you plan to rely on Section 21 before the reform date, you need to understand the transition cut-offs. Atalaw summarises the key point clearly: you may still be able to issue a claim on a valid pre-commencement Section 21 notice after commencement, but only within strict deadlines (including a hard stop linked to 31 July 2026 for legacy claims, depending on the “earlier of” rule).
Tighten evidence habits now
Under the new world, your success is often decided by the quality of your paperwork:
- rent ledgers and arrears schedules
- inspection notes and repair logs
- ASB incident logs, reports, witness notes
- proof that you acted reasonably and proportionately
If repairs are in the background of your dispute (and they often are), don’t ignore it — disrepair arguments can complicate possession. If you’re a tenant dealing with repair issues, you may find Housing Disrepair Services London useful, and the practical guide Using EPA Part III (statutory nuisance) when repairs stall: tenant step-by-step explains an alternative route.
Budget for the real cost of delays (not just legal fees)
If you do end up issuing proceedings, there are direct costs. For example, the Government’s possession claim online route (for rent arrears cases) lists a £404 fee.
But the bigger financial risk is usually time:
- months of rent exposure if arrears continue
- mortgage and service charge outgoings
- insurance and compliance costs
- delayed sales and refinancing
This is exactly why notice planning is now a risk management exercise, not a formality.
When you should take early legal advice
You should strongly consider getting advice early if:
- you’re relying on a “must win” deadline (sale, move-in, refinance)
- there are arrears with a messy payment history
- disrepair is likely to be raised as a defence or counterclaim
- the tenant may be vulnerable (and you need to handle communications carefully)
- you’re not confident your deposit, documents, and prescribed info history is clean
If your dispute overlaps with wider issues (contract, enforcement, debt), it may also touch other areas such as Civil litigation or Debt Recovery.
