For as long as most landlords have been letting property, the worst case was containable. If a tenancy went wrong, Section 21 gave you a defined way out. You did not have to prove anything. You served notice, and in most cases the tenant left.
That route closed on 1 May 2026.
Every possession in England now runs through Section 8, which means proving a ground to a court. Most landlords have absorbed that as a piece of legislation. Far fewer have worked through what it does to the economics of a single bad letting.
It changes them completely, and it moves the most important decision in the whole process right to the beginning: who you hand the keys to.
What a failed tenancy actually costs
Take the most common failure, which is rent arrears.
Ground 8 is the mandatory arrears ground, the one where the court must order possession if the conditions are met. Since May, the threshold has been three months of unpaid rent rather than two. So before you can even serve notice, three months of rent has already gone.
Then there is four weeks' notice, up from two.
Then you file a claim. The most recent Ministry of Justice figures, covering April to June 2026, put the median time from a landlord filing a possession claim to actually getting the property back at 27.1 weeks. That is a little over six months. It has fallen slightly over the past year, from 27.9 weeks, but it remains far longer than most landlords assume when they picture going to court.
Add those together and you are looking at roughly ten months from the first missed payment to standing in your own property again.
What that costs depends on where you let. The latest Office for National Statistics figures put average monthly private rents at £1,213 across Eastleigh borough, which covers Hedge End and Fair Oak, £1,253 in Southampton, which covers Bitterne, and £1,504 across Winchester district, which covers Bishop's Waltham. Ten months of lost rent is therefore somewhere between £12,000 and £15,000 depending on the property, and that is before court fees, legal costs, any repairs needed at the end, and the void period while you re-let.
A court can award you a money judgment for the arrears. Collecting it is a separate problem.
The part most landlords have not been told
Ground 8 has a trap in it.
The three months of arrears must exist both on the day you serve notice and on the day of the hearing. A tenant who pays a few hundred pounds shortly before the hearing drops below the threshold, and the mandatory ground fails. You are then left arguing a discretionary ground, where the court decides whether eviction is reasonable, having already lost several months.
There is a second adjustment worth knowing. Where arrears exist because a Universal Credit housing payment has not reached the tenant, that amount is stripped out of the calculation for the mandatory ground.
Neither of these is a reason to panic. Both are reasons to make sure the problem never gets that far.
And from later this year, Section 8 comes with a precondition
One more change is worth building into your planning now, because it affects the only possession route you have left.
The second phase of the Renters' Rights Act introduces a national database of landlords and rental properties in England, which the government has confirmed will be called Register your rental property. It began testing with real landlords and properties over the summer and will roll out region by region from late 2026, with national coverage expected during 2027. Registration will be mandatory, will carry an annual fee, and will require your contact details, property information and current gas, electrical and energy performance certificates.
The detail that matters is what happens if you are not on it. An unregistered landlord cannot rely on the possession grounds. So the route described above, slow as it already is, does not open at all until you have registered.
Which is another argument for keeping the certificates and the paperwork in one place rather than across three folders and an email account.
Which is why tenant selection is now the whole game
If unwinding a bad tenancy takes the best part of a year, the first real protection is not letting to the wrong person at all.
Proper referencing is not a credit check. It is affordability tested against the actual rent rather than a rough multiple. Employment verified with the employer, not just with a document the applicant supplied. The previous landlord contacted directly and asked the questions that matter. And any guarantor assessed to the same standard as the tenant.
It also means reading what the references do not say. A previous landlord who confirms the dates and offers nothing else has told you something.
The highest offer is not always the best tenant
This is the point that most often catches out landlords managing on their own.
When two applicants want the property and one offers above the asking rent, the temptation is obvious. But an applicant stretching to afford a property is an applicant with no margin when their circumstances change, and circumstances change.
An extra £50 a month is £600 a year. A tenancy that fails costs twenty times that. The strongest applicant is usually the one who can comfortably afford the rent, has a settled reason for being in the area, and can be verified quickly.
Why landlords across south Hampshire can afford to be selective
Demand here supports a careful approach. In the year to June, average rents rose 3.4% across Eastleigh borough and 3.6% across Winchester district, both ahead of the 2.3% recorded across the wider South East, and the demand behind that is structural rather than temporary.
In Hedge End and the villages around Bishop's Waltham and Fair Oak, it is families who want the schools and the space. In Bitterne, much of it comes from hospital staff, the port economy and the universities on the other side of the Itchen, which means applications tend to arrive quickly and in volume.
A well-presented property in any of these areas will generate multiple applications. That is precisely the position from which you can afford to turn the wrong one down.
Referencing tells you about a moment, not about the next five years
Here is the part that changes what selection on its own can achieve.
Under the Renters' Rights Act, every tenancy is now periodic from day one. There is no fixed term and no end date, which means there is no longer a natural point at which everyone stops and reassesses. A tenancy you selected perfectly in 2026 simply continues until somebody ends it.
So the applicant who referenced impeccably can still lose their job in 2028. Referencing tells you who somebody is on the day they apply. It cannot tell you what happens in year three, and there is now no fixed term coming to an end to catch it.
Which is why what happens after move-in matters as much as who moved in.
Most arrears cases that reach three months did not begin there. They began with one late payment that nobody chased properly. A managed tenancy monitors rent from the first day it is due, contacts the tenant the moment a payment is missed, and documents every step. That documentation is what a court needs to see later, and it is usually the reason a court is never needed at all.
Regular inspections do the same job for condition. A problem found at a six-month inspection is a repair. The same problem found at the end of a tenancy is a deposit dispute.
On a let-only arrangement, all of that sits with you.
Choosing a letting agent is part of choosing the tenant
There is one more thing worth saying plainly, because it affects the quality of the selection itself.
A letting agent who only finds you a tenant is paid when that tenant moves in. A letting agent who manages the property has to live with the same tenant for as long as the tenancy runs, which under the new rules could be many years. That difference shows up in how carefully an application gets assessed, and it is worth asking any agent about directly.
White and Guard has been letting and managing property across south Hampshire for twenty years, across our four branches. We are independent and locally owned, so the person who lets your property is the person accountable for how it runs.
If you are letting a property yourself, the question worth asking is not whether you are doing it well. It is what happens if it goes wrong, and how quickly you would know.
Talk to your local branch about moving to full management, or about how we reference applicants before you decide. Either conversation is free, and neither commits you to anything.
