For almost 40 years since The Housing Act was introduced in the UK in 1988, getting a property back came down to one thing: serving the right notice at the right time.

Section 21 let a landlord end a tenancy without giving any reason, as long as the fixed term had ended and the notice period was met. But that route has now closed. With no-fault evictions gone, getting your property back rests almost entirely on proving a case under Section 8, unless you intend to sell the property or you or a close family member plans to move in permanently.

You can only evict by relying on one of its legally defined reasons, known as possession grounds. And proving the ground you’re using comes down to the records you can put in front of a court.

There’s an urgent deadline before any of the bigger changes settle in. If you served a Section 21 notice before the new rules took effect, you have until 31 July to get your case to court. In most cases, if court proceedings have not been started by 31 July 2026, landlords will lose the ability to rely on that Section 21 notice.

After that, every possession claim goes through Section 8. That means relying on a defined ground and proving it holds, rather than just serving notice and waiting out the time.

The problem is bigger than it looks

The first deadline has already passed, and the signs are that a lot of landlords have missed it. Every existing tenant was meant to get a government information sheet explaining how the Renters’ Rights Act changes their tenancy. The cut-off was 31 May, and if missed, you’re exposed to a penalty of up to £7,000 per tenancy.

So how many landlords actually did it? A Freedom of Information request, obtained by Landlord Studio from the housing ministry, found the official sheet was downloaded around 153,000 times in the first four weeks after publication. There are an estimated 2.3 million landlords meant to issue it. Even allowing for agents serving it on behalf of several clients at once, that’s a long way short. It tells you most of the market was running behind on the new rules, if it had started at all.

And the information sheet is the easy part. It’s in one document that’s sent once. The harder change is what sits underneath it. The rules don’t just affect how you end a tenancy, they change what you have to prove. And proof is something you build over months. You can’t put it together the week before a hearing.

Possession now comes down to paperwork

Under Section 8 you have to prove the ground you’re relying on. For rent arrears, still the most common reason, that means showing the arrears are real, and that they’re high enough on the day of the hearing as well as the day you served the notice.

In practice, landlords relying on rent arrears will usually need a clear and dated arrears schedule showing what was due, what was paid and how the balance changed over time. A rough total you’ve added up after the event doesn’t carry the same legitimacy. The same goes for any ground that rests on what the tenant did or a breach of the agreement. If it isn’t written down, then it’s your word against theirs. That’s a weak place to start.

Your correspondence matters just as much. A clear, dated record of what you said to the tenant and when, which includes reminders, notices and any attempt to sort things out, is often what decides whether a claim holds up in court.

The mistakes already showing up

This isn’t a new problem. Section 8 possession has always leaned on evidence. The landlords who struggle usually aren’t the ones without a case. They’re the ones who can’t prove the case they have.

The gaps here are familiar. Cash is taken by hand and never logged, so the arrears figure can be argued over due to a lack of proof. Reminders and warnings are sent by text, then lost when a phone gets replaced. A payment plan is agreed verbally, but now exists only in someone’s memory rather than on paper. On their own, none of these feels like a big deal, but when put together, they give the tenant’s side an easy way to throw doubt on everything.

The facts were never the problem. The record was.

What to do before it costs you

The solution is simple, but it has to start now, not when a tenancy goes wrong.

First, landlords should gather what they can while it’s still there. This includes bank statements, old messages and signed agreements. Pull it all into one running record for each tenancy. Second, landlords should log everything from here on. Every payment on the day it lands, and every bit of contact with the tenant, dated and saved somewhere it won’t get lost.

Finally, keep your arrears record live. Update it as you go rather than rebuilding it under pressure. A running balance you can produce at any moment is worth far more than one you throw together in a hurry.

Doing all of this by hand is where most people slip. It’s the kind of admin that’s easy to put off and easy to lose. This is where the right property management software earns its place. A good system logs each payment as it lands and keeps every document in one place whilst building your arrears history as you go. You’re not hunting through old texts and bank statements the week before a hearing. The record is already there, because something has been keeping it the whole time.

This isn’t about expecting the worst from your tenants. Most tenancies never go near a court. It’s about making sure that, if one does, your position is as strong as your case deserves.

A change in habits, not just rules

It’s easy to see the end of Section 21 as landlords losing control. It’s really more of a change in discipline. Your reason for wanting the property back still has to be genuine. That was always true. What’s changed is that you now have to show it on paper.

Landlords who already run their lettings like a business won’t find much of this new. The ones who’ve relied on informal habits and a good memory have the most to do and the least time to do it.

The 31 July deadline is the first thing to deal with. The bigger picture is that keeping good records has gone from sensible to essential. It’s now the thing that decides whether you get your property back at all.
