What Is Section 8 Ground 1B?

Ground 1B is a new mandatory possession ground in Schedule 2, Part 1 of the Housing Act 1988, inserted by the Renters' Rights Act 2025 and effective across England from 1 May 2026. It allows a private landlord to seek possession of a property let on an assured tenancy where the landlord genuinely intends to demolish the building or carry out substantial works of redevelopment, and those works cannot reasonably be carried out with the tenant remaining in occupation.

It is a mandatory ground. If the landlord satisfies the court that both conditions are met — genuine redevelopment intention and incompatibility with continued occupation — the judge must grant possession. Unlike discretionary grounds (Ground 10, Ground 14), the court cannot weigh up the circumstances and decline once the ground is proved.

✓ Ground 1B — key facts

→ Mandatory — court must grant if proved

→ 4 months' minimum notice period

→ Genuine redevelopment intention required

→ Works must require vacant possession

→ Planning permission (or application) strongly advisable

⚠ Ground 1B and the abolition of Section 21

Section 21 “no-fault” eviction was abolished from 1 May 2026 under the Renters' Rights Act 2025. Ground 1B was introduced as part of the same legislative package to ensure landlords with genuine redevelopment plans retain a clear legal route to possession. It is specifically designed for cases where vacant possession is a genuine operational necessity — not a pretext.

When Does Ground 1B Apply? Redevelopment Scenarios Explained

To use Ground 1B, the landlord must satisfy two cumulative conditions at the court hearing. Both must be true simultaneously — satisfying only one is not enough:

Condition A — Genuine redevelopment intention

The landlord intends to demolish the property or carry out substantial works of redevelopment on it, or a part of it that the tenant occupies. The intention must be genuine, settled, and supported by concrete plans — not a vague aspiration or a pretext for recovering possession.

Condition B — Works require vacant possession

The proposed works cannot reasonably be carried out while the tenant remains in occupation. If the works could be done room by room, wing by wing, or while the tenant temporarily vacates a single space, Ground 1B is unlikely to succeed. The incompatibility must be fundamental.

Does your redevelopment qualify? — Common scenarios:

ScenarioLikely to qualify?Notes
Full demolition of the building✓ YesDemolition plainly cannot proceed with a tenant in occupation. Ground 1B is designed for this.
Conversion of a house into flats requiring structural changes✓ YesSubstantial structural works affecting habitability. Works cannot reasonably proceed around an occupant.
Extension or complete internal reconfiguration affecting all rooms✓ YesWhere the scale of works makes the property uninhabitable throughout, Ground 1B may apply. Evidence from a structural engineer is essential.
Change of use — residential to commercial requiring planning permission✓ YesWhere planning permission is granted and the entire property must be vacated, Ground 1B can support possession.
Cosmetic refurbishment (new kitchen, bathroom, flooring)✗ NoDoes not meet the "substantial works" threshold. Minor renovation cannot support a Ground 1B claim.
Single-room works where the tenant could remain elsewhere in the property✗ NoIf the tenant could reasonably remain in part of the property during works, Ground 1B will fail.
Works the landlord intends to carry out at an unspecified future date✗ NoIntention must be genuine, fixed, and substantiated. Vague future plans will not satisfy the court.
Landlord wishes to sell and buyer intends to redevelop✗ NoThe redevelopment intention must be the landlord's own. A buyer's intention does not ground Ground 1B. Consider Ground 1A (selling) instead.

Evidence Required to Support a Ground 1B Redevelopment Claim

Ground 1B is mandatory, but courts scrutinise it carefully precisely because it requires tenants to vacate through no fault of their own. Prepare these documents before serving the notice.

1

Planning permission or pre-application correspondence

Where planning permission is required (almost always for substantial redevelopment), produce either the granted permission or evidence a full application is in progress. Pre-application advice from the local planning authority also supports genuine intention.

2

Architect's drawings or structural engineer's report

Professional drawings or a structural survey confirming the scale and nature of the proposed works. These must show that the works are genuine, designed, and of a scale that requires vacant possession.

3

Evidence the works cannot proceed with the tenant in occupation

A statement from the contractor, structural engineer, or architect confirming that the works require full vacant possession — for example because the entire structure will be affected, utilities must be disconnected, or the building will be uninhabitable throughout.

4

Contractor quotes or signed building contract

A signed quote or contract with a named contractor, showing the scope of works, estimated duration, and proposed start date. This demonstrates that the redevelopment is not merely a future aspiration.

5

Landlord's signed witness statement

A detailed witness statement from the landlord (or managing director if a company) setting out the genuine intention to redevelop, the reasons vacant possession is required, and the proposed timeline.

6

The tenancy agreement

A copy of the tenancy agreement naming all tenants, confirming it is an assured tenancy, and showing the property address that is the subject of the redevelopment.

7

Certificate of service

Proof that the Form 3A Section 8 notice was properly served on the tenant with the correct date and method of service. Without this the court cannot list a possession hearing.

📌 Practical example — house conversion to flats

A landlord owns a three-storey Victorian house let on a single assured tenancy. The landlord has obtained planning permission from the local planning authority to convert the house into five self-contained flats, requiring full structural reconfiguration on every floor. An architect has confirmed that the works require the building to be completely vacated. The contractor has provided a signed quote with a proposed start date of six months hence. The landlord serves a Section 8 notice on Form 3A citing Ground 1B, giving 4 months' notice. If the tenant does not vacate by the expiry date, the landlord files Form N5 at the county court with all the supporting evidence.

⚠ Courts are alert to pretextual Ground 1B claims

Where the landlord obtains possession under Ground 1B and then re-lets immediately without redeveloping, the tenant (or a regulator) may challenge this as a bad-faith use of the ground. The Renters' Rights Act 2025 introduced enhanced protections in this area. Always seek legal advice before proceeding if there is any uncertainty about the permanence and scale of the proposed works.

Notice Period for Ground 1B and How to Complete Form 3A Correctly

Ground 1B requires a minimum of 4 months' notice from the date the tenant receives the Section 8 notice. This is one of the longer Section 8 notice periods, reflecting the significant disruption caused to a tenant who has done nothing wrong. The clock starts from the date of receipt by the tenant, not the date the notice was written or posted.

How to complete Form 3A for Ground 1B

Ground cited

Ground 1B of Schedule 2 of the Housing Act 1988. You may also cite other grounds on the same Form 3A — for example, Ground 1A (selling) if the landlord is selling after redevelopment — but cite only grounds that genuinely apply.

Reason for possession

State clearly that you intend to demolish or carry out substantial redevelopment works. Describe the nature of the works, reference the planning permission, and confirm they cannot proceed with the tenant in occupation.

Service and expiry dates

The expiry date must be at least 4 months from the date of service. For first-class post, add two working days to the posting date to determine when service occurs. Our generator calculates the expiry date automatically.

Tenant names and property address

Must exactly match the tenancy agreement. Full property address including postcode. All joint tenants must be named — a notice missing any tenant is defective.

📌 How notice periods are counted

The 4-month notice period runs from when the tenant receives the notice. For first-class post, HMRC and court practice treats service as occurring two working days after the date of posting. Add those days to your posting date before calculating the expiry. Do not count the service date itself in the 4-month period. Our generator handles this calculation for you.

Ground 1B — Step-by-Step Process for Landlords

01

Confirm the tenancy type

Ground 1B applies to assured tenancies in England only. Check the tenancy agreement was created after 15 January 1989 and is not a company let, licence, or regulated tenancy.

02

Secure planning permission and professional reports

Before serving any notice, obtain planning permission (or at minimum a formal pre-application submission), architect's drawings, and a structural engineer's report confirming vacant possession is required.

03

Obtain a contractor quote or signed building contract

A signed quote or contract with a named contractor showing the scope, start date, and duration of works is the clearest evidence of genuine redevelopment intention. Courts are sceptical of bare plans without commercial commitment.

04

Serve Section 8 notice on Form 3A citing Ground 1B

Complete Form 3A, select Ground 1B, state the reason for possession clearly — describing the proposed works — and calculate the expiry date: at least 4 months from the date the tenant receives the notice. Use OfficeDraft's generator to produce the correct Form 3A PDF.

05

Complete and retain a certificate of service

Immediately after serving, complete a signed certificate of service recording the date, method, and person who served the notice. The county court will require this document when you file your possession claim.

06

Apply to court if the tenant does not vacate

If the tenant remains after the expiry date, file Form N5 (possession claim) at your local county court with all supporting evidence. Ground 1B is mandatory — if proved, the judge must grant possession.

Ground 1B Compared to Related Section 8 Grounds

Several Section 8 grounds overlap in practical terms with Ground 1B. Understanding the differences helps landlords choose the correct ground — or combination of grounds — for their situation.

Ground 1B vs Ground 1A (landlord selling)

Ground 1A applies where the landlord intends to sell the property with vacant possession. Ground 1B applies where the landlord intends to redevelop. They serve different purposes: selling and redeveloping are distinct intentions, though a landlord might sell after redeveloping. Both require 2 months' (Ground 1A) and 4 months' (Ground 1B) notice respectively and can be cited on the same Form 3A if both genuinely apply.

Ground 1B vs Ground 1 (landlord moving in)

Ground 1 applies where the landlord or a qualifying family member intends to occupy the property as their main home. Ground 1B applies where the landlord intends to redevelop it. They are mutually exclusive purposes. Ground 1 requires 2 months' notice; Ground 1B requires 4 months'.

Ground 1B vs Ground 6 (demolition or reconstruction — previously)

Before the Renters' Rights Act 2025, Schedule 2 included Ground 6, which covered demolition and substantial reconstruction for assured tenancies. Ground 1B effectively replaces and consolidates this ground in the new legislative framework. If you are reviewing older possession cases, references to "Ground 6" in this context relate to the predecessor provision.

What Happens After the Ground 1B Notice Expires?

Once the Section 8 notice expires, the landlord cannot force the tenant out without a court order. Unlawful eviction — changing locks, removing the tenant's belongings, disconnecting utilities — is a criminal offence under the Protection from Eviction Act 1977 ↗, regardless of whether the Section 8 ground is valid.

✓ Tenant vacates voluntarily

The tenant leaves by the expiry date. No court claim is needed. Conduct a check-out inspection, return the deposit minus legitimate deductions, and retain all documentation relating to the Ground 1B claim for at least 12 months in case of any subsequent challenge.

✗ Tenant does not vacate

File Form N5 (possession claim) at your local county court, attaching all supporting evidence: the Form 3A, planning permission, architect's drawings, contractor quotes, and certificate of service. Ground 1B is mandatory — if proved, the judge must grant possession. Apply for a warrant of eviction (Form N325) if the tenant remains after the possession order.

⚠ 12-month validity of the Section 8 notice

A Section 8 notice remains valid for 12 months from the date of service. If you have not issued court proceedings within 12 months, you must serve a fresh notice before filing a possession claim. If planning permission has lapsed or the redevelopment plans have changed materially, seek legal advice before re-serving.

7 Mistakes That Invalidate a Ground 1B Possession Claim

Ground 1B claims are resource-intensive and fail more often than landlords expect. Courts apply close scrutiny to any non-fault possession ground. Avoid these errors before serving your notice.

1.

Serving Ground 1B for minor or cosmetic works

Ground 1B requires substantial redevelopment — demolition or works that genuinely prevent occupation. A new kitchen or bathroom does not qualify. The court will dismiss the claim and may award costs against the landlord.

2.

No planning permission and no evidence of a genuine application

A bare statement that redevelopment is intended, without planning permission or formal pre-application correspondence, will almost certainly fail. Courts require evidence of a concrete, progressed plan.

3.

Using old Form 3 instead of Form 3A

All Section 8 notices must be served on Form 3A from 1 May 2026. A notice on the old Form 3 is legally invalid and the county court will dismiss the possession claim.

4.

Notice period shorter than 4 months

Ground 1B requires a minimum of 4 months' notice from the date of service. A notice giving less notice is defective and cannot support a court claim.

5.

Serving the notice before obtaining planning permission

If planning permission is refused after the notice is served, the ground may fail at court. Best practice is to secure permission before serving. At minimum, have a formal application submitted and architectural drawings ready.

6.

Re-letting the property immediately after possession

Courts are alert to landlords who obtain possession under Ground 1B and then re-let rather than redevelop. Such conduct may support a claim that the ground was used in bad faith. The Renters' Rights Act 2025 introduced enhanced protections against this.

7.

Incorrect or incomplete tenant names on the notice

Every tenant on the tenancy agreement must appear on the Section 8 notice, spelt exactly as in the agreement. Any discrepancy may be used to challenge the notice.

Ground 1B and the Renters' Rights Act 2025 — What Changed

Ground 1B is one of several new or significantly amended grounds introduced by the Renters' Rights Act 2025, which came into force on 1 May 2026. Understanding the legislative context is important for any landlord or property professional advising on possession proceedings.

🏗

New Ground 1B introduced

Ground 1B is a new ground in Schedule 2, providing landlords with a clear, codified route to possession for genuine redevelopment. Previously, similar possession claims were pursued under Ground 6, which had a narrower scope and different procedural requirements.

🚫

Section 21 abolished

From 1 May 2026, landlords can no longer serve Section 21 "no-fault" notices. Ground 1B is part of the package of fault-based and need-based grounds that replace Section 21 for landlords with genuine operational reasons for requiring possession.

📋

Form 3A replaces Form 3

The Renters' Rights Act 2025 introduced a new prescribed form — Form 3A — for all Section 8 notices. The old Form 3 is legally invalid from 1 May 2026. All Ground 1B notices must be served on Form 3A.

🛡

Enhanced bad-faith protections

The Act introduced enhanced protections against landlords who obtain possession under grounds like 1B and then re-let without redeveloping. Courts and regulators can scrutinise post-possession conduct. Genuine intention is therefore both a legal requirement and a practical necessity.

Frequently Asked Questions — Section 8 Ground 1B Redevelopment

What is Section 8 Ground 1B?▾
Ground 1B is a mandatory possession ground introduced by the Renters' Rights Act 2025, in force from 1 May 2026. It allows a landlord to seek possession of an assured tenancy in England where the landlord genuinely intends to demolish or carry out substantial redevelopment works, and those works cannot reasonably be carried out with the tenant in occupation. A Section 8 notice on Form 3A must be served giving at least 4 months' notice.
Is Ground 1B mandatory or discretionary?▾
Ground 1B is a mandatory ground. If the landlord proves the conditions at the court hearing — genuine intention to redevelop and works that require vacant possession — the judge must grant a possession order. The court cannot exercise discretion to refuse, even on compassionate grounds.
What notice period does Ground 1B require?▾
Ground 1B requires a minimum of 4 months' notice from the date the tenant receives the Section 8 notice. This is one of the longest notice periods in Section 8, reflecting the scale of disruption to the tenant. If posting first class, add two working days to the posting date to determine the date of service. Our generator calculates the expiry date automatically.
What evidence does a landlord need to support a Ground 1B claim?▾
Courts apply close scrutiny to Ground 1B claims because they require tenants to vacate through no fault of their own. Landlords should assemble: granted planning permission (or a formal pre-application submission), architect's drawings, a structural engineer's or contractor's statement confirming vacant possession is required, a signed contractor quote or building contract, and the landlord's own witness statement. Vague statements of future intention are unlikely to succeed.
Can a landlord re-let the property after obtaining possession under Ground 1B?▾
No — not immediately, and not without serious risk. Ground 1B requires a genuine intention to redevelop. A landlord who obtains possession and then re-lets the property without carrying out the works may face claims that the ground was used in bad faith. The Renters' Rights Act 2025 introduced measures to strengthen tenant protections in this area. Seek legal advice before commencing any Ground 1B proceedings where there is any doubt about the redevelopment plans.

Ground 1B involves a fact-sensitive assessment of the nature, scale, and genuineness of proposed redevelopment works. Every case is different. Before commencing any Ground 1B possession proceedings, we strongly recommend seeking independent advice from a qualified housing solicitor, particularly where planning permission has not yet been granted, where the works are close to the borderline of “substantial,” or where the tenant is likely to defend the claim.
