Homes (Fitness for Human Habitation) Act 2018: the section 9A tenant claim walkthrough (2026)

A flat with bedroom damp running halfway up the wall, a kitchen extractor that has not worked since the tenant moved in, a boiler that cuts out three times a week, a flat above a takeaway with cooking smells and vermin no one will deal with — these are the cases section 9A was written for. Before 2019, a tenant facing this kind of unfitness had to either persuade their local environmental health team to act, or shoehorn the complaint into section 11 of the Landlord and Tenant Act 1985, which is narrower and requires formal notice. The Homes (Fitness for Human Habitation) Act 2018 changed that by inserting section 9A into the 1985 Act — a fitness covenant implied into every short tenancy, enforceable by the tenant themselves in the county court, with no notice requirement.

This walkthrough is for a tenant living in a property that is in poor condition and wants to know how to bring, or threaten, a section 9A claim. It covers what the fitness covenant says, how the 29 HHSRS hazards feed into it, the difference from section 11, the Pre-Action Protocol for Housing Conditions Claims, the evidence the case turns on, the N1 court route, the remedies on offer (damages, specific performance, repair order), and how it sits alongside Awaab's Law and the Decent Homes Standard. There is a templated letter before claim at the end with the 20-working-day clock baked in — that letter is the single most useful piece of correspondence a tenant in this position can send.

What section 9A actually says

Section 9A of the Landlord and Tenant Act 1985, inserted by the Homes (Fitness for Human Habitation) Act 2018 and in force from 20 March 2019 for new tenancies and 20 March 2020 for all tenancies, implies into a lease of a dwelling for less than 7 years a covenant by the lessor that the dwelling is fit for human habitation:

• At the time the lease is granted, and
• At all times during the term of the lease.

It is a continuous covenant. The landlord is not just promising the dwelling will be fit when the keys are handed over — they are promising it will stay fit for as long as the tenancy lasts. If unfitness arises, the landlord is in breach. If they fix it, they are no longer in breach. If they let it fester, the breach continues and the damages run alongside it.

The "fit for human habitation" test is set out in section 10 of the 1985 Act, as amended. A dwelling is unfit if it is so far defective in one or more of the following respects that it is not reasonably suitable for occupation in that condition: repair, stability, freedom from damp, internal arrangement, natural lighting, ventilation, water supply, drainage and sanitary conveniences, facilities for the preparation and cooking of food and disposal of waste water. The list is then extended by the 29 Category 1 and Category 2 hazards of the Housing Health and Safety Rating System (HHSRS) under the Housing Act 2004 — meaning any prescribed hazard at a Category 1 level, and many at Category 2, is capable of making the dwelling unfit.

The 29 HHSRS hazards

The HHSRS is the technical assessment framework local authority environmental health teams use, and it is the framework a surveyor will use when producing a section 9A report. The 29 hazard categories, grouped roughly: physiological (damp and mould, excess cold, excess heat, asbestos, biocides, carbon monoxide, lead, radiation, uncombusted fuel gas, volatile organics); psychological (crowding and space, entry by intruders, lighting, noise); protection from infection (domestic hygiene, food safety, personal hygiene, water supply); and protection from accidents (falls on the level, falls on stairs, falls between levels, falls in baths, electrical hazards, fire, hot surfaces, collision and entrapment, explosions, position and operability of amenities, structural collapse).

Each hazard is scored numerically and rated Category 1 (most serious) or Category 2. A Category 1 hazard puts the dwelling unfit almost automatically. A Category 2 hazard can do so depending on severity and combination with others. A surveyor's report that flags two or three Category 2 hazards in combination is a strong section 9A case.

How it differs from section 11

This distinction matters because tenants and even some landlords get them muddled.

Section 11 is narrower. It covers disrepair — that is, the structure and exterior of the dwelling, and certain installations (gas, water, electrics, heating, sanitary). It requires the defect to have actually broken (you cannot rely on section 11 for inherent design defects that have not failed). And critically, it requires the tenant to have given the landlord notice of the defect and a reasonable opportunity to repair. Without notice and opportunity, no breach.

Section 9A is broader and more demanding on the landlord. It covers fitness, which includes condensation damp from poor ventilation, inadequate heating, fire risk from missing alarms, electrical hazards, overcrowding, vermin, and many things that are not "disrepair" in any meaningful sense — they are inherent or design problems that make the dwelling unfit. It does not require notice. The landlord must keep the dwelling fit; if it is unfit, they are in breach.

You can plead both in the alternative, and tenants regularly do. Section 11 covers the broken boiler. Section 9A covers the inherent damp the landlord has never addressed. Damages can flow under either or both.

The Pre-Action Protocol for Housing Conditions Claims

Before a tenant can issue a section 9A claim in the county court, the Civil Procedure Rules expect them to follow the Pre-Action Protocol for Housing Conditions Claims (England). The protocol is not technically mandatory but a court will look unfavourably on a tenant — or a landlord — who has ignored it, and costs orders can flow accordingly.

The protocol does three useful things:

It sets the timetable. The tenant sends an early notification letter (optional but useful) and then a letter of claim. The landlord has 20 working days to respond with a full reply that says either they admit the claim and what they propose to do, or they deny it and why. They must disclose specified documents in their reply.

It opens disclosure early. The landlord is required to disclose documents the tenant would otherwise have to extract on disclosure later — gas safety records, electrical certificates, EPCs, the tenancy agreement, repair history, surveyors' reports, asbestos surveys.

It steers the case to settlement. Most section 9A cases settle in the protocol phase — once the landlord realises the surveyor's evidence is real and the damages exposure is mid-thousands rather than nothing, the calculation usually shifts.

The clock starts when the letter of claim is received. Use recorded delivery or email with read receipt and keep proof.

Letter before claim under section 9A of the Landlord and Tenant Act 1985 — template

Send this letter (with the surveyor's report ideally already attached, but if not, signalling that one is being commissioned) by email and by recorded delivery. Keep copies of both.

Dear [Landlord / Agent name],

Re: [Property address] — Letter before claim, section 9A of the Landlord and Tenant Act 1985

1. I am the tenant of the above property under a tenancy granted on [date]. I write in accordance with the Pre-Action Protocol for Housing Conditions Claims.

2. The property is not fit for human habitation. In particular:

   a. [Description of hazard 1, location, date first arose, any photographic evidence] — this is a HHSRS Category [1 / 2] hazard of [hazard category].

   b. [Description of hazard 2, location, date first arose] — HHSRS Category [1 / 2] hazard of [hazard category].

   c. [Description of hazard 3, etc.]

3. The conditions described above amount to a breach by you of the implied covenant of fitness for human habitation under section 9A of the Landlord and Tenant Act 1985. The covenant is continuous and applies for the duration of the tenancy. The breach has subsisted since at least [date].

4. I have raised these matters with you previously by [list — e.g. emails dated 3 February 2026, 18 February 2026 and 4 March 2026; copies attached]. The works have not been carried out.

5. [If applicable] A copy of an independent surveyor's report dated [date] is enclosed. The surveyor has assessed the property and identified the hazards above using the HHSRS framework.

6. I request that within 20 working days of receipt of this letter you:

   a. Confirm whether you accept that the property is unfit for habitation.

   b. Set out a programme of works, with start and completion dates, to remedy the unfitness.

   c. Make a proposal for damages for the period of unfitness to date. I will provide a calculation if helpful.

   d. Provide, in accordance with paragraph 5.5 of the Pre-Action Protocol, copies of: the tenancy agreement, gas safety records for the last 6 years, electrical installation condition report, EPC, asbestos survey if held, repair and maintenance records for the property, any inspection reports, and the landlord's complaints policy.

7. If a satisfactory response is not received within 20 working days, I will consider issuing proceedings in the county court seeking specific performance, damages, and an order for costs.

8. I am willing to settle this matter without litigation and would welcome a constructive reply.

Yours, [Name, date]

If the 20 working days elapse without a full reply, you are in a position to issue. If the reply is partial or evasive, you can press for completion — and either way, the absence of a proper reply is a costs point at the end of the case.

Evidence — what wins these cases

Section 9A claims are won on documents. The five pillars of evidence: dated photographs (with the date visible in file metadata — wide shots and close-ups), diary log (a chronological list of date, what happened, who was told, what they said), correspondence pack (every email and letter to the landlord with their replies or annotation showing none received), surveyor's report (a RICS-qualified surveyor experienced in HHSRS assessments — typically £400-£600, often arrangeable on no-win-no-fee terms through Shelter or a housing solicitor), and medical and impact evidence (GP letters confirming any health condition affected by the conditions, receipts for ruined possessions, bills for additional heating).

A bundle with these five elements puts a section 9A claim into "this will probably settle" territory long before trial.

The N1 court route

If the protocol does not resolve matters, the tenant issues a claim using Form N1 in the county court. The court fee is on a sliding scale based on the damages sought (typically £35-£500 for claims under £10,000 — many section 9A claims fall here for the damages element, with the works order being non-monetary). Fee remission is available for tenants on means-tested benefits.

The claim form pleads:

• Section 9A of the Landlord and Tenant Act 1985 (and where relevant section 11 in the alternative).
• The unfitness — list each hazard.
• The breach — that the landlord has failed to keep the dwelling fit despite knowledge / despite the surveyor's report.
• The remedies sought — specific performance (an order requiring named works to a named timetable), damages for the period of unfitness, special damages for consequential loss, costs.

Many county courts list a case management conference first, where directions are set for disclosure, expert evidence (the surveyor), witness statements, and a trial date. Section 9A trials are typically half a day to a day. Most cases settle before trial.

The remedies

Three remedies are commonly sought and granted.

Specific performance. A court order requiring the landlord to carry out specified works by a specified date. The order is enforceable — failure to comply is contempt. Most landlords comply once an order is in place because the alternative is significantly more painful.

General damages. Damages for the discomfort, inconvenience and reduced amenity of living in an unfit property. Calculated typically as a percentage of the rent paid during the period of unfitness. 25-50% of rent is the usual range, with single rooms uninhabitable giving lower percentages and whole-flat severe unfitness giving higher. A two-year claim at 30% of £900 rent is £6,480 — meaningful money.

Special damages. Money to compensate specific provable losses — replacement of ruined clothes, bedding, furniture, electronics; additional heating bills; alternative accommodation costs where the tenant has had to move out temporarily; medical costs not covered by the NHS.

The court can also order that, if the landlord fails to do the works in the timeframe set, the tenant may instruct contractors and recover the cost — a "self-help" remedy that focuses minds.

How it sits alongside Awaab's Law and Decent Homes

Section 9A is not the only fitness route, and the landscape has thickened considerably in the last 18 months.

Awaab's Law (covered separately in our 2026-05-07 walkthrough) imposes strict statutory time limits on social landlords for emergency hazards and damp and mould, with the Housing Ombudsman as the enforcement mechanism. It applies to social tenants only, and works through the regulator, not the courts.

The Decent Homes Standard (covered separately in our 2026-05-07 walkthrough) is being extended to the private rented sector under the Renters' Rights Act 2025, and is enforced by local authority environmental health teams.

Section 9A is the tenant's own private right of action. It pre-dates both of those frameworks, survives both of them, and is available to any tenant of any short tenancy (private or social) in England — directly, in the county court, without needing the regulator or the council to act first.

The three routes are not alternatives. They reinforce each other. A tenant can complain to the Housing Ombudsman under Awaab's Law, can complain to environmental health under HHSRS or the Decent Homes Standard, and can issue a section 9A claim in the county court — at the same time. Each route puts pressure on a different part of the landlord's organisation, and a landlord facing all three usually moves.

When to use RentSOS

RentSOS focuses on rent increase challenges under Section 13 rather than disrepair, but housing conditions and rent are tightly connected. If your landlord is putting up the rent on a property that is, on any honest view, not fit for habitation, you have two parallel arguments to make: section 9A on the condition, and a Section 13 challenge on the rent itself. The RentSOS check will tell you whether the increase notice has procedural defects and whether the proposed rent is justifiable against local comparables. A poor EPC, flood risk, and below-market amenity all feed into both arguments. Running a section 9A claim and a Section 13 challenge in parallel is one of the strongest positions a tenant in this situation can be in.

A calmer last word

A home in poor condition is hard to live in, and the prospect of taking the landlord to court can feel out of proportion to the energy available. Section 9A was written to change that — to give tenants a direct, enforceable, named right that does not depend on environmental health priorities or the goodwill of an Ombudsman scheme. The pre-action protocol is the path of least resistance: a clear letter, a 20-working-day clock, a surveyor's report, and most of the time the landlord moves before a claim is ever issued. Build the evidence carefully, send the letter calmly, and remember that an enforceable repair order is, in practical terms, the outcome most tenants actually want.
