Section 21 notice pending? Deadline is 31 July

If you served a Section 21 notice on a tenant before the Renters' Rights Act changed the rules on 1st May 2026, and that tenant is still in the property, the clock is louder than you might think. You now have until 31st July 2026 to get your court claim issued, not just posted or submitted, but issued by the court. In practice, that means getting your claim issued by the court, not just sent off: under the civil procedure rules, proceedings only formally start once the court has issued the claim form, so a form posted on the 30th with the court still working through a backlog may not count in time. Miss it, and the notice you served simply stops working.

This matters for a small but real group of landlords: those who served a valid Section 21 (no-fault) notice before the cut-off and haven't yet been through the courts. If that's you, here's exactly what the deadline means and what to do with the next three weeks.

Why there's a deadline at all

Section 21 was abolished when the Renters' Rights Act's new tenancy system came into force on 1st May 2026. Fixed-term assured shorthold tenancies became periodic assured tenancies overnight, and landlords lost the ability to serve new Section 21 notices from that date.

But notices served before 1st May weren't cancelled outright. The government built in a transition window so landlords partway through the eviction process wouldn't be left stranded. Under those transitional rules, a valid pre-1st May notice can still be used to apply for possession, but only up to a fixed long-stop date, and that date is 31st July 2026.

More precisely, according to the government's own guidance, you can only use your notice to start court proceedings up to and including whichever date comes first: the time left on the notice itself, or 31st July 2026. Every Section 21 notice already carries its own built-in cut-off for starting court action; the transitional rules haven't extended that, they've simply capped it at 31st July 2026 for anyone still inside their original window. For most landlords who served relatively recently, the 31st July date will be the one that applies, but it's worth checking your own notice rather than assuming.

Section 8 notices served before 1st May are on the clock too

It isn't only Section 21 that's affected. If you served a Section 8 notice before 1st May 2026 and haven't yet started proceedings, the same kind of squeeze applies. Under the government's guidance, you can only rely on that notice up to whichever comes first: 12 months from the date you gave it, or three months on from 1st May 2026, which lands on 1st August 2026. If your Section 8 notice was served early on, this can cut what would normally have been a full 12 months, so check your own dates rather than assuming you have longer.

Start proceedings, don't just post the paperwork

The deadline is about starting court proceedings, not simply sending something off. Possession courts in England have been running with backlogs of several weeks in many areas, and the government's guidance is clear that claims made on or after 1st August 2026 are unlikely to succeed even where a notice was served in good time. If you're planning to rely on your notice, the sensible approach echoed by housing solicitors is to file well ahead of the deadline, not in the final days.

What to do this week

1. Check your notice is still valid. A Section 21 notice can be defeated on technical grounds as well as timing ones. Confirm the tenant's deposit was protected within the required timeframe, that you gave them the prescribed information, a current gas safety certificate, a valid EPC and the government's How to Rent guide at the right point. Courts have thrown out otherwise timely claims over gaps like these.
2. Work out your actual deadline. Check the expiry built into your own notice. If that falls before 31st July, that earlier date is the one that binds you, not the long-stop, so don't assume you automatically have until the end of July.
3. Choose the right form. If you're only seeking possession and not claiming rent arrears, the accelerated procedure using form N5B lets the court decide on paperwork alone in most cases, without a hearing. If you also want to recover unpaid rent, you'll need the standard N5 procedure instead, which does involve a hearing.
4. File without delay. Given court processing times, treat the 31st July date as a last resort, not a target. Filing several weeks ahead gives the court time to actually issue the claim before the window closes.
5. Have a fallback ready. If there's any chance your claim won't be issued in time, start preparing a Section 8 notice in parallel so you're not starting from zero if the Section 21 route closes.

What happens if you miss it

If 31st July passes and your claim hasn't been issued, the Section 21 notice becomes unenforceable. The tenancy carries on as a periodic assured tenancy and you'll need to start again using a Section 8 notice. That means picking a specific ground for possession, such as selling the property, moving in yourself, or rent arrears, and providing evidence to support it. The tenant can challenge the ground in court, so the process tends to take longer and requires more from the landlord than the old no-fault route did.

It isn't the end of the road if you need possession, but it is a slower and more evidence-heavy one, so it's worth avoiding if your existing notice is still usable.

If you don't have a pending notice, none of this applies to you

It's worth saying plainly: these deadlines only affect landlords who served a Section 21 or Section 8 notice before 1st May 2026 and are still relying on it. If every notice you've given was served after that date, none of the above changes anything for you: any possession claim you make will already be going through the current Section 8 grounds and timescales.

Getting it right without the stress

Possession claims are one of the areas where a small paperwork slip can cost weeks or months, especially with a hard deadline in play. If you're managing this alongside everything else that comes with letting a property, and you'd rather not be the one chasing court forms at 11pm, our fully managed service takes the administrative load off your hands, including keeping compliance paperwork in order so notices hold up when they need to.

And if this situation has you thinking about whether it's time to relet with a clean slate rather than go through a possession claim at all, our tenant find service can help you find your next tenant quickly once the property is free.

Whatever route applies to you, the takeaway is simple: if you have a pending Section 21 notice, don't wait for the deadline to remind you. Check your paperwork, file this week if you can, and have a Section 8 backup ready just in case.
