The Renters Rights Act killed Section 21 on 1 May 2026. Here is how Section 8 grounds actually work, ground by ground, with notice periods and proof.
If you own rental property in England, the way you take possession has changed for good. Section 21, the so called no fault notice that quietly underpinned the private rented sector for thirty years, is gone. Every possession claim from 1 May 2026 onwards must rest on a Section 8 ground. That sounds clinical until you realise it is the difference between getting your property back in four weeks and losing twelve months in the county court.
This week we walk through the post Renters Rights Act grounds in detail. Which are mandatory. Which are discretionary. What notice periods apply. And the evidence you need to keep on file so the day you do need to serve, your claim does not collapse on a technicality.
Before the Act, there were seventeen possession grounds. There are now thirty seven. That sounds like more options, and in some respects it is, but the real shift is structural. You are no longer choosing between Section 21 (quick, no reason needed) and Section 8 (slow, reason required). You are choosing between Section 8 grounds, and every ground demands paperwork, notice, and in many cases hard evidence the court can test.
The grounds split into two big buckets. Mandatory grounds mean the court must grant possession if you prove the facts. Discretionary grounds mean the judge can refuse even if you prove the facts, if they think eviction is unreasonable. Mandatory is what you want where it is available. Discretionary is what you live with when it is not.
The other shift worth flagging up front: notice periods have lengthened. The headline grounds (sale, moving in, redevelopment) now require four months of notice. Rent arrears mandatory has moved from two months to three months in arrears, with four weeks notice. That changes your cash flow planning, your insurance arrangements, and your tolerance for slow paying tenants.
Mandatory grounds are the workhorse of post RRA possession. If you can fit your situation into one of these and prove it, the court grants possession. Here are the ones you need to know.
Ground 1, landlord or close family moving in. Previously this was you, your spouse, or civil partner. The Act widens it to close relatives (parent, child, sibling, grandparent, grandchild, and step versions of the same). You must give four months notice and you cannot use this ground in the first twelve months of the tenancy. If you re let the property within twelve months of the tenant leaving without the named relative actually moving in, you are exposed to a civil penalty of up to £40,000 in serious cases. Refer to gov.uk for the current cap and further guidance.
Ground 1A, sale of the property. Entirely new. You must intend to sell with vacant possession, give four months notice, and again you cannot use it inside the first twelve months. The same twelve month re letting bar applies. The evidence the court will look for includes a signed estate agency agreement, a memorandum of sale, or correspondence with a conveyancer. Vague “thinking about selling” will not survive a contested hearing.
Ground 6, redevelopment. You intend substantial works that cannot be done with the tenant in situ. Four months notice. Expect to produce planning permissions, builder quotes, and a realistic timetable.
Ground 6A, compliance with enforcement. New ground covering situations where you are required by an enforcement notice (banning order, HMO licensing decision, prohibition order) to take possession. Four months notice. You will need the relevant order on file.
Ground 8, serious rent arrears. The big one. The threshold has moved from two months to three months arrears for monthly tenancies, or thirteen weeks for weekly. Four weeks notice. Crucially, any arrears the tenant clears caused by a delayed Universal Credit payment do not count toward the threshold. That is a significant carve out and a reason to confirm UC status before serving.
“The single biggest change is not that Section 21 has gone. It is that every notice you serve now has to survive contested scrutiny. Sloppy paperwork is the new void.”
Discretionary grounds are where landlords get caught out. The court can refuse possession even with proof, so you need both the facts and a clean conduct record on your side.
With discretionary grounds, the gap between winning and losing is almost always the documentation. A landlord with a date stamped log of complaints, photographs, contemporaneous emails, and a clean rent ledger wins. A landlord with a memory and a few WhatsApps does not.
Notice periods under the new regime are the single biggest source of pub conversation confusion. Here is the clean version:
Get the notice period wrong and your Section 8 notice is invalid. You cannot quietly cure it later. You serve again, the clock restarts, and your tenant has another four months or more in the property. This is not a place to guess.
From talking to letting agents and landlords across England in the first ten days post commencement, three patterns are already emerging.
One: serving on the wrong ground. Some landlords are reflexively defaulting to Ground 8 because they have heard “rent arrears” is the easy one. If the arrears sit below three months, Ground 8 fails. You needed Ground 10 or 11. Same facts, different ground, different notice period, different outcome.
Two: skipping the Information Sheet. Every assured tenant must receive the government Information Sheet by 31 May 2026, or at the start of a new tenancy. If you have not served it and you go to court on a Section 8 ground, expect the judge to take a dim view. The Act is explicit that prescribed information is a precondition to certain enforcement steps.
Three: poor record keeping on rent arrears. The Universal Credit carve out in Ground 8 means you need to know, at the date you serve, whether any of the arrears are caused by a UC payment delay. If they are, you strip them out and the remaining arrears may fall below threshold. Landlords who cannot tell UC delayed arrears from genuine arrears are walking into avoidable failed claims.
The fix for all three is unglamorous: a clean tenancy file, a real rent ledger, dated copies of every notice served, and a clear record of what ground applies to what fact pattern. Proxera exists to make that file build itself in the background, so when you do need to serve, the evidence is already there. See how it works for agents.
If any one of those eight steps is shaky, your possession claim is shaky. Tidy them up before you serve, not after.
The Renters Rights Act has turned every landlord into part time evidence officer. Proxera pulls your rent ledger, tenancy documents, compliance certificates, and correspondence into one place so the file for any Section 8 claim is built quietly, in the background, while you get on with running your portfolio. See what’s included from £14.95/month.
For letting agents, Proxera’s agency workspace lets you serve, track, and document Section 8 notices across every managed property, with audit trails your insurer and your clients will actually thank you for. See the agent workspace. If you are still running this on spreadsheets and a shared Dropbox, you are one contested hearing away from a very bad afternoon.
The landlords who win in the post Section 21 era are not the ones with the angriest notices. They are the ones with the cleanest files.
Build the file before you need it. The day you do need it, you will not have time to fix it under pressure.
