Section 8 Ground 1A evidence threshold: the tenant defence playbook for landlords claiming sale or move-in (May 2026)

A Section 8 notice citing Ground 1A lands on the doormat. Your landlord says they want to sell. Or move back in. The notice gives you four months to leave. It feels final.

It isn't. Ground 1A is the most evidence-tested possession ground in the post-Renters' Rights Act 2025 toolkit. It is mandatory — if the landlord proves it, the tribunal must grant possession — but the proof bar is real, and the consequences for getting it wrong are large. A landlord who serves Ground 1A and then relets the property within 12 months is exposed to a Rent Repayment Order recovering up to a year of rent.

This guide is for tenants. It walks through what Ground 1A actually requires, the five evidence categories you should probe, how it differs from Ground 1, the 12-month relet rule, three plain-text response templates, and a 30-minute playbook for the moment the notice arrives. Stay calm. You have levers.

What Ground 1A actually requires

Ground 1A was inserted into Schedule 2 of the Housing Act 1988 by the Renters' Rights Act 2025. It allows a landlord to seek possession of an assured tenancy on the basis that they intend to sell the property (or, in a separate strand often discussed alongside it, that the landlord or a close family member intends to move in — see "Ground 1A vs Ground 1" below for how the family-member route now sits).

Three things matter:

• Notice period: four months. The landlord must give at least four months' notice in writing on Form 4A. The notice cannot be served in the first 12 months of the tenancy.
• Mandatory ground. If the landlord proves the ground at the First-tier Tribunal Property Chamber (or, where the case proceeds in the county court, before the judge), the tribunal must grant possession. There is no discretion.
• The proof bar. "Mandatory if proven" cuts both ways. The landlord must show a genuine, settled intention to sell — not a vague plan, not a "might sell next year". Intention is a question of fact, and facts need evidence.

That last point is the whole game. Ground 1A is not a magic word. It is a claim the landlord has to back up. Most don't realise how much.

The five evidence categories a tenant should probe

When you receive a Ground 1A notice, your first job is not to pack. It is to ask — politely, in writing — for the evidence behind the stated intention. The landlord is not legally required to hand over their estate-agent paperwork before tribunal, but a refusal to engage at this stage is itself useful at hearing.

Probe across five categories.

1. Ownership and intention to sell

Has the landlord instructed an estate agent? Is there a draft agency agreement? A valuation letter? A signed sale memorandum? A buyer's solicitor on record? Each rung up the ladder is harder to fake.

What to ask for: a copy of the agency instruction or valuation letter, dated before the Ground 1A notice was served. Dates matter — see "Timing of decision" below.

2. The no-pretence test

The tribunal will ask whether the stated intention is genuine or a pretext to remove the tenant. If the landlord has previously raised the rent aggressively, refused repairs, or made the tenancy unpleasant, that history is relevant context — not proof of bad faith on its own, but the kind of pattern a tribunal will weigh.

What to gather: your own paper trail. Repair requests, rent increase notices, any messages where the landlord expressed frustration with the tenancy. Keep it factual.

3. The family-member test (if move-in is the basis)

If the notice cites a family member moving in, the landlord must specify who, in what relationship, and when. "My daughter" is not enough on its own — they must be a "close family member" within the statutory definition (broadly: spouse or civil partner, child, parent, grandparent, sibling, or the equivalent step-relations).

What to ask for: the name and relationship, and the proposed move-in date. A vague answer is itself an answer.

4. Genuine intention (history matters)

Has this landlord served a Ground 1A or equivalent notice before, and then not sold? Have they advertised the property for let in the last 12 months? Have they previously told you in writing that they planned to keep letting?

What to do: search the property's address on Rightmove and Zoopla rental history (some listings persist in cached pages). Check the agent's window. If you have old emails or texts saying "I'll never sell this place", screenshot them.

5. Timing of the decision

Did the stated intention to sell crystallise before you raised a complaint, requested a repair, refused a rent increase, or asserted a tenancy right? Or did it appear suspiciously soon after?

Sequence is hard for a landlord to rewrite. Note the dates of any disputed events and place them on a single timeline alongside the Ground 1A notice date.

None of these five categories is a knockout blow on its own. Together, they let you build a picture of how solid the landlord's case actually is. They also give the tribunal — if you reach one — something to work with.

Ground 1A vs Ground 1: what's the difference?

Both grounds existed in some form before the Renters' Rights Act 2025, and both are mandatory. The differences are who and why.

Ground 1 covers the landlord (or a specified close family member named in the original tenancy agreement) returning to occupy the property as their only or principal home. It requires that the landlord previously occupied the property as their only or principal home, or that prior written notice was given to the tenant at the start of the tenancy that Ground 1 might be relied on.

Ground 1A, in the form expanded by the 2025 Act, covers the landlord's intention to sell the property with vacant possession, and (in its move-in strand) the landlord or a close family member intending to occupy it as their only or principal home, regardless of whether prior notice was given at the start of the tenancy.

Practical difference for tenants: Ground 1A is the broader, more commonly served ground. Ground 1 has a "prior notice at tenancy start" requirement that catches a lot of landlords out — if your original tenancy agreement does not flag Ground 1, the landlord may have to fall back on Ground 1A, which carries the 12-month relet trap.

The 12-month RRO trap — your 12-month watchlist

This is the part landlords forget. If a landlord obtains possession via Ground 1A and then relets the property within 12 months of the notice expiring (or the tenant leaving, whichever is later), the former tenant can apply to the First-tier Tribunal Property Chamber for a Rent Repayment Order.

Key facts:

• Application fee: £300. Help with Fees is available if you are on a low income or qualifying benefits — full or partial fee remission depending on circumstances.
• Maximum recovery: 12 months of rent. The tribunal has discretion on the exact amount, weighing the seriousness of the breach and the landlord's conduct, but 12 months is the ceiling.
• Forum: First-tier Tribunal (Property Chamber). Not the small claims court. The procedure is tenant-friendly — you do not need a solicitor, and the tribunal is used to litigants in person.
• Time limit: generally 12 months from the date of the offence. Don't sit on it.

Your job, if you leave under a Ground 1A notice, is to monitor. For 12 months. Set a calendar reminder.

Your watchlist:

• Rightmove and Zoopla — search the exact address weekly. Save any listing as a PDF the moment you see it.
• OnTheMarket and the high-street agent windows in your old neighbourhood. A landlord who served Ground 1A and quietly went to a different agent is the classic relet pattern.
• Land Registry alerts. You can sign up for free property alerts at the Land Registry — you'll be told if the title changes hands. If no sale completes within 12 months and the property is back on the rental market, the picture is clear.
• Council tax records. In some areas, council tax records are publicly searchable enough to confirm whether a new tenant has moved in.
• Neighbours. If you stayed friendly with anyone on the street, ask them to flag if new tenants appear. Not surveillance — just awareness.

A relet within 12 months does not mean the landlord acted in bad faith automatically. Circumstances change. But it shifts the burden, and the tribunal will want to hear why the stated intention dissolved so quickly.

Three response templates (plain text)

These are starting points. Adapt to your situation. Send by email if you have one for your landlord; otherwise, post by signed-for delivery and keep the receipt.

Template A — Acknowledge receipt and request supporting evidence

Dear [Landlord name],

I confirm receipt of your Section 8 notice on Form 4A dated [date], citing Ground 1A.

So that I can take proper advice and plan accordingly, please provide the following supporting information within 14 days:

1. The basis on which you are relying on Ground 1A (sale, move-in by you, or move-in by a close family member).
2. If sale: a copy of the estate-agent instruction letter or valuation report, dated.
3. If move-in by a family member: their name, relationship, and proposed move-in date.
4. The expected date by which possession is sought.

I am taking this notice seriously and will respond properly. Engaging with these questions now will help avoid disputes later.

Yours sincerely, [Your name]

Template B — Challenge a weak intention with specific evidence asks

Dear [Landlord name],

Thank you for your reply of [date]. I am not satisfied that the stated intention under Ground 1A is supported by the information you have provided to date.

Specifically:

• You have not provided dated evidence of an instruction to sell (estate-agent letter, valuation, or sale memorandum).
• On [earlier date], you stated in writing that [quote — e.g., "I have no plans to sell"]. I attach a copy.
• The notice was served shortly after [event — e.g., my request for repairs to the boiler on (date) / my refusal of the proposed rent increase on (date)].

I am not refusing to leave. I am asking that the ground be properly evidenced. If the matter proceeds to the First-tier Tribunal, I will be raising these points and asking the tribunal to test the genuineness of the stated intention.

I remain open to a sensible discussion, including a mutual surrender on agreed terms.

Yours sincerely, [Your name]

Template C — Post-move-out RRO application notice

Dear [Former landlord name],

I vacated [property address] on [date] in compliance with your Section 8 notice on Form 4A citing Ground 1A.

I am now aware that the property has been relet. [Specifically: the property was advertised on Rightmove on (date) — listing attached / a new tenant has moved in as confirmed by (source).]

Under the Renters' Rights Act 2025 framework, this raises the prospect of a Rent Repayment Order. I am writing to give you the opportunity to explain the change of circumstances within 14 days. If I do not receive a satisfactory explanation, I intend to apply to the First-tier Tribunal Property Chamber for a Rent Repayment Order recovering up to 12 months of rent.

Yours sincerely, [Your name]

Five common landlord mistakes that weaken Ground 1A

These are the patterns the tribunal sees over and over. If your landlord is doing one of them, note it.

1. Vague intention. "I'm thinking of selling" is not the same as a settled intention. The tribunal wants a fixed plan, not a maybe.
2. Notice served just after a tenant complaint or rent dispute. Sequence is the first thing the tribunal looks at.
3. No instruction to an agent and no for-sale evidence. A bare assertion with nothing behind it is the weakest possible case.
4. Family-member move-in with no named family member. A landlord who cannot say who will be moving in is not ready.
5. Prior written contradiction. Any email, text, or message from the landlord saying they intend to keep letting cuts directly against a later Ground 1A claim.

30-minute first-response playbook

Got the notice today? Do this in the next half hour.

1. Don't reply yet, don't panic-pack. Put the kettle on. Take a breath.
2. Photograph the notice and the envelope. Date stamp on the postmark matters. Save copies in cloud storage you control.
3. Open a single document called ground-1a-timeline.md (or paper if you prefer) and start a dated timeline. Notice date at the top. Add the date you signed the tenancy, the date of any rent increase, the date of any repair request, the date of any dispute.
4. Read the notice carefully. Confirm it is on Form 4A. Confirm the four-month notice period. Confirm the date possession is sought is at least four months from the notice date and after the first 12 months of the tenancy.
5. Send Template A (above) within 7 days. Polite, factual, evidence request.
6. Book a free legal call. Citizens Advice (0800 144 8848) or Shelter (0808 800 4444). Both can talk through the notice for free. If the notice has technical defects, they'll spot them.

That's the first 30 minutes. The next four months are about evidence, options (negotiate a mutual surrender? ask for more time? proceed to tribunal?), and — if you do leave — setting your 12-month watchlist.
