Homes (Fitness for Human Habitation) Act 2018 — Landlord Obligations and Tenant Rights

The Section 9A implied covenant — what landlords must ensure

Section 9A LTA 1985 (as inserted by the 2018 Act) imposes two distinct obligations on landlords:

• Fitness at commencement: The dwelling must be fit for human habitation at the time the tenancy is granted. A landlord who lets a property that is, at the outset, unfit for habitation is in immediate breach of Section 9A — regardless of whether the unfitness arises from a matter within the landlord's or tenant's control. The obligation to ensure fitness at commencement is absolute
• Maintenance of fitness throughout the tenancy: The dwelling must be kept fit for human habitation throughout the tenancy. This is not merely an obligation to repair when defects arise — it is a continuing obligation to maintain the property at a standard that makes it fit for the purpose of human habitation. If the property becomes unfit during the tenancy for any reason within the landlord's control (or within the control of the building's structure, external fabric, or common parts), the landlord is in breach
• The 29 categories of hazard: Section 9A incorporates by reference the 29 categories of hazard under the Housing Health and Safety Rating System (HHSRS). A property is 'unfit for human habitation' if it has any of these hazards to a degree that makes it not reasonably suitable for occupation. The 29 categories include: damp and mould growth; excess cold; excess heat; asbestos and MMF; biocides; carbon monoxide; lead; radiation; uncombusted fuel gas; volatile organic compounds; crowding and space; entry by intruders; lighting; noise; domestic hygiene, pests, and refuse; food safety; personal hygiene, sanitation and drainage; water supply; falls associated with baths; falling on level surfaces; falling on stairs; falling between levels; electrical hazards; fire; flames and hot surfaces; structural collapse and falling elements; uncombusted fuel gas; and explosions
• The 'fitness' standard: The fitness standard under s.9A is not the HHSRS Category 1 hazard threshold (which applies to local authority enforcement). The county court applies an objective test of whether the dwelling is reasonably suitable for occupation having regard to all relevant circumstances. A dwelling can be unfit for habitation even where no HHSRS Category 1 hazard exists — a persistent Category 2 hazard that makes living conditions difficult may still breach s.9A
• Common parts obligation: Where the landlord has an estate or interest in the common parts of a building (for example, a freehold landlord of a flat who also owns the staircase and communal hallways), the s.9A obligation extends to those common parts. A damp problem originating in the roof or external walls of the building (which are within the landlord's control) can give rise to a s.9A breach in the individual flat, even if the flat itself is otherwise well maintained

Tenant's right of action — how tenants enforce Section 9A

The 2018 Act's most significant innovation is the tenant's direct private law right to sue in the county court:

• County court claim — no local authority involvement needed: A tenant who believes the property is unfit for human habitation can bring a claim in the county court directly against the landlord — without needing to first report to the local authority. The claim is under the Landlord and Tenant Act 1985 s.9A. The claim can be brought in the tenant's local county court and many tenants now have access to legal aid, no-win-no-fee solicitors, or tenants' rights organisations that can assist with the claim
• Remedies available: The county court can award: (1) a mandatory injunction requiring the landlord to carry out specified works to make the property fit for habitation within a specified timescale; (2) damages for the period during which the property was unfit for habitation — including damages for personal injury, distress, inconvenience, and loss of enjoyment of the property. Damages in habitability claims can be substantial where the unfitness has persisted for months or years
• Quantum of damages: Damages for breach of the habitation covenant are typically calculated as a proportion of the rent paid for the period of unfitness, plus any additional damages for health impacts, personal injury, or consequential losses. In severe cases involving prolonged damp and mould, structural defects, or persistent vermin, damages awards of £10,000-£50,000 are not uncommon. The First-tier Tribunal (Property Chamber) can also hear related rent repayment order applications where the unfitness is connected to an unlicensed HMO
• Tenant's duty to notify the landlord: The s.9A obligation only arises (for defects arising during the tenancy) once the landlord has been notified of the condition. A landlord who is unaware of a defect that has caused unfitness cannot be liable under s.9A until notification. Tenants should notify in writing (email or letter) — and the date of notification starts the clock for the landlord's response obligation. After notification, the landlord must act within a reasonable time to assess and remedy the condition
• Interaction with Awaab's Law: From 27 October 2025, Awaab's Law (Awaab Ishak's Law) applies to all private tenancies under the Renters' Rights Act 2025. Awaab's Law imposes specific timescales for responding to health hazards (investigation within 14 days, written report within a further 14 days, works commenced within a reasonable period and within 7 days for emergencies). A landlord in breach of Awaab's Law timescales is also likely to be in breach of s.9A. The two obligations operate in parallel — Awaab's Law sets the timescale framework while s.9A provides the tenant's private law remedy

Landlord defences — what landlords can and cannot rely on

The Section 9A obligation is not absolute — several defences are available:

• Tenant's own default: Where the unfitness arises from the tenant's own breach of their obligations — such as failure to ventilate rooms causing condensation mould, accumulation of rubbish creating a pest hazard, or deliberate damage — the landlord has a defence to the extent the unfitness was caused by the tenant's conduct. The defence requires the landlord to prove the causal link between the tenant's conduct and the unfitness. Evidence from pre-tenancy and periodic inspection reports is critical
• Matters beyond the landlord's control: Where the unfitness arises from an event or condition beyond the landlord's reasonable control (for example, a sudden flood from a neighbouring property, an extreme weather event, or a defect concealed within the structure that a reasonable inspection could not have identified), the landlord may have a partial defence. The landlord must still act promptly once the condition is identified
• Property exceeding the £3,500 cost cap: The 2018 Act does not excuse the landlord from the fitness obligation where the cost of works exceeds the MEES £3,500 cost cap. The fitness obligation and the MEES obligation are distinct — the fitness obligation is a condition of the tenancy and cannot be deferred on cost grounds
• Lack of notification: As noted above, where the tenant has not notified the landlord of the condition, the landlord cannot be in breach of the continuing fitness obligation for defects arising during the tenancy. This is not a full defence — the landlord must have systems to identify obvious unfitness issues during periodic inspections, and cannot wilfully close their eyes to obvious problems
• What landlords cannot rely on: A landlord cannot defend a s.9A claim by arguing: the property was fit when let (if it subsequently became unfit); the works are too expensive; the planning authority has not given permission for necessary works; or the lease terms do not require certain repairs. Section 9A is non-excludable — no contractual term can reduce the landlord's obligation below the statutory standard

Practical compliance — maintaining fitness for habitation

A proactive approach to property maintenance is the most effective defence against s.9A claims:

• Pre-tenancy fitness inspection: Before granting a new tenancy, carry out a thorough inspection of the property to identify any HHSRS hazards. The HHSRS 29-category checklist should be used systematically. Document the inspection in writing, including photographs. Any hazards identified must be remedied before the tenancy commences. A property let with a known hazard is in immediate breach of s.9A
• Respond to repair notifications promptly: When a tenant reports a defect or condition, record the notification in writing (confirm by email), arrange an inspection within a reasonable time (typically within 7-14 days for standard issues, within 24 hours for emergencies), and commence necessary works as soon as possible. Under Awaab's Law, specific timescales now apply. Keep all records of notifications, inspections, contractor instructions, and completed works
• Periodic inspections: Quarterly property inspections (with 24 hours' written notice to the tenant) allow early identification of condensation mould, structural issues, plumbing leaks, and other hazards before they become s.9A breaches. An inspection that identifies a hazard and results in prompt remediation is evidence of good landlord practice — and reduces both the risk of litigation and the quantum of any damages
• Damp and mould — the most litigated area: Damp and mould is the HHSRS Category 1 hazard most frequently the subject of s.9A claims and Awaab's Law enforcement. Landlords must distinguish between: condensation damp (caused by tenant behaviour and typically not a landlord obligation under s.11 — but potentially a s.9A issue if structural ventilation is inadequate) and penetrating or rising damp (a landlord obligation under both s.11 and s.9A). All mould complaints must be investigated — a response letter attributing mould to the tenant's lifestyle without investigation is a significant litigation risk
