Section 21 has gone. Now your evidence file is the case

For years, a Section 21 notice rewarded a particular kind of landlord. The one whose paperwork was simply present and correct. Get the prescribed information served, the deposit protected, the gas certificate in date, and the right form completed, and you did not have to explain yourself. You did not need a reason. The documents just had to exist.

Since 1 May 2026 that world has gone. Section 21 is abolished, and possession claims in England now run through Section 8 of the Housing Act 1988. The government’s own landlord guidance puts it plainly. You can only end a tenancy where you have a legally prescribed reason that you can evidence. That last word is the whole game. Your paperwork no longer just has to be present. It has to persuade a judge.

Mandatory and discretionary are not the same fight

Section 8 grounds split into two camps, and the split decides what your evidence has to do.

For a mandatory ground, if you prove the ground, the court must make a possession order. There is no balancing exercise. Your task is narrow but unforgiving. Prove the facts, cleanly, on the documents.

For a discretionary ground, proving the ground is only half the battle. Even when you have made it out, the court still asks whether it is reasonable to grant possession, weighing your evidence against the tenant’s circumstances. Here a thin file does not just slow you down. It can lose you the case, because reasonableness is argued, and arguments tend to be won on evidence.

Rent arrears: the ledger is your witness

The mandatory ground most landlords will reach for is Ground 8, for serious rent arrears. The Act raised the threshold from two months to three, and extended the notice period from two weeks to four. The point that trips people up is the timing. The arrears generally have to be at the required level both when you serve the notice and again at the hearing. A tenant who pays the balance down below the threshold before the hearing may defeat a Ground 8 claim.

This is why a clean, contemporaneous rent record matters so much, and why many landlords also plead the discretionary arrears grounds alongside Ground 8, so that a last minute payment does not leave them with nothing. What a judge will want to see is a rent ledger that is clear, consistent, and obviously kept in real time, rather than one assembled the week before the hearing. If your record of who paid what and when is a scatter of bank screenshots and best guesses, you may be starting on the back foot.

The discretionary grounds live or die on detail

The grounds causing landlords the most heartache now tend to be the discretionary ones, and the comment threads on this site tell the story. Breach of the tenancy agreement, deterioration of the property, and antisocial behaviour are all grounds where you can be entirely in the right and still lose, because you cannot prove it to the standard a reasonableness test demands.

Antisocial behaviour may be the hardest of all. Ground 14 is discretionary, and the familiar problem is that neighbours will happily complain to you and then go quiet when asked to put their name to a statement. A dated, detailed incident log kept as events happened is likely to carry more weight than a recollection offered months later. The same goes for property damage under Ground 13, where dated photographs and a paper trail of reported issues do the work, and for breaches under Ground 12, where you would generally need the clause, the breach, and evidence that the tenant knew the obligation.

I am not going to pretend documentation guarantees a result. Outcomes on discretionary grounds depend on the judge and the facts. But the difference between a landlord who kept records as they went and one who did not is often the difference between a hearing that goes ahead and one that falls apart.

The failures that sink you before grounds are even discussed

There is one more shift worth flagging, because it operates before anyone looks at your grounds at all. The government has confirmed that a court will not be able to make a possession order if you have not protected the tenant’s deposit in an approved scheme. Once the private rented sector database is operational, registration is expected to become a similar precondition, although that part of the Act is not yet in force, so I would treat it as something on the horizon rather than a current bar. Notably, these restrictions are not intended to apply to the antisocial behaviour grounds.

The practical lesson is an uncomfortable one. You could have an unanswerable case on the merits and still be turned away at the door because a deposit was mishandled years ago. The compliance basics are no longer just good housekeeping. They may be the gate you have to pass through to be heard at all.

Build the file before you need it

The thread running through all of this is that the evidence has to exist before the dispute does. You cannot manufacture a contemporaneous record after the fact, and a judge can often tell when someone has tried.

So the unglamorous advice is the honest advice. Keep the rent ledger current. Log incidents on the day. Keep dated proof of every notice served and every certificate in date. Keep the deposit paperwork where you can find it in minutes. The case is now the file, and the file has to be built long before you walk into court.

At LLCR, this is the problem I built the platform to solve. It gives self-managing landlords one place to keep the rent ledger, the served notices, the dated incident logs, and every certificate, so the evidence is being built as the tenancy runs rather than scrambled together before a hearing. Each document is timestamped at upload and tamper evident, so if a notice or a certificate is ever questioned, you can show what existed, in what form, and when.

Not sure where your gaps are? LLCR’s free compliance checker runs through the legal requirements for your tenancy in minutes.

Tell us your experience

Section 21 made paperwork a box-ticking exercise. Section 8 makes it the heart of the case. The landlords who come through the next year in the best shape will not be the ones with the strongest opinions about the reforms. They will be the ones who can open a file and show a judge exactly what happened, and when.

For those who have been through a Section 8 hearing since May, what did the judge actually want to see, and what did you wish you had kept? And on the antisocial behaviour grounds in particular, has anyone found a way to get reluctant neighbours to give evidence that holds up in court? A lot of us are going to learn this the hard way, so the practical experience is worth sharing.
