The Homes (Fitness for Human Habitation) Act 2018 came into force on 20 March 2019. It has been a legal obligation on private landlords for over seven years. Despite that, it remains one of the least understood pieces of housing legislation in the private rented sector — and one of the most powerful tools available to tenants.

This edition covers what the Act actually requires, how it connects to HHSRS, what the 29 hazards are, what tenants can do if a property is unfit, and — critically — how two changes that came into force on 1 May 2026 have made this obligation significantly more serious for landlords than it was before.

The Homes Act does not introduce new obligations. This is the most important thing to understand about it. The Act doesn't introduce new responsibilities for landlords but reinforces their duty to meet existing standards and safety requirements in rental properties.

What it did was give tenants a direct route to court to enforce those obligations without needing to go through the council first. Before the Act, a tenant with a serious disrepair problem had to complain to the local authority and wait for environmental health to act. The Act created a direct implied covenant — written into every tenancy by law — requiring the landlord to ensure the property is fit for human habitation at the start of and throughout the tenancy.

All landlords have a statutory duty to ensure their properties are fit for human habitation at the start and throughout the tenancy. That duty exists whether or not a tenant knows about it, whether or not they mention it, and whether or not any council inspection has ever taken place. The Independent Landlord

The implied covenant works in two directions. The property must be fit at the start of the tenancy — so a landlord who lets a property with existing defects they knew about is immediately in breach. And the property must remain fit throughout — so a landlord who fails to respond to reported disrepair that renders the property unfit is in ongoing breach for every day the defect persists.

Tenants can take legal action against their landlord for breaches of this statutory duty. The court can order repairs, award damages for inconvenience (typically £1,000 to £10,000 in run-of-the-mill cases), compensation for damaged belongings, and reduced rent for the period of unfitness. Personal injury claims are available where health has been affected, with potentially unlimited damages. Shelter England

That last category — personal injury where health has been affected — is the one that carries the most serious financial exposure. A tenant whose health has genuinely been damaged by prolonged damp and mould exposure can bring an unlimited damages claim. Combined with a repair order and compensation for inconvenience, the total exposure in a serious case can be substantial.

When determining whether a home is unfit for human habitation, regard must be had to its condition in respect of the property's overall condition, structural stability, serious issues with damp, unsafe layout, inadequate natural light or ventilation, insufficient hot and cold water supply, drainage or lavatory issues, inadequate facilities for cooking and washing up, and any of the hazards outlined in the Housing Health and Safety Rating System.

The HHSRS hazards sit at the heart of the fitness assessment. The Housing Health and Safety Rating System (England) (Amendment) Regulations 2026, as updated in June 2026 now covers 21 hazards in the amended framework — the system has been updated alongside the Renters' Rights Act changes. northtyneside

The most commonly identified hazards in private rented properties are:

Damp and mould — the single most common cause of fitness claims. Persistent moisture, condensation that the property's ventilation cannot address, or structural dampness that the landlord has failed to investigate or remedy.

Excess cold — properties that cannot maintain adequate temperatures, particularly affecting vulnerable occupants. A broken boiler not repaired promptly is the most common example.

Electrical hazards — unsafe installations, overloaded circuits, exposed conductors. An EICR identifies these but not fixing remedial items is where liability arises.

Falls on stairs — broken handrails, damaged steps, inadequate lighting. The Category depends heavily on occupant profile — Category 2 in a household of young adults, Category 1 where an elderly or disabled occupant is using the stairs daily. The same physical defect can jump categories based on who is at risk. Shelter England

Fire — inadequate fire detection, blocked escape routes, unsafe gas appliances.

Structural collapse — any element of the property at serious risk of failure.

The fitness assessment is not a pass/fail checklist. It requires consideration of the severity of any hazard and the vulnerability of the occupants. A defect that is a minor inconvenience to a healthy young adult can be a serious risk to an elderly, disabled or immunocompromised occupant in the same property.

The county court assesses the case by reference to the implied covenant and the HHSRS framework. The tenant brings the claim using the N1 Claim Form. If the problem persists and the landlord still refuses to act, the tenant can apply to the County Court under the Homes (Fitness for Human Habitation) Act 2018. Legislation.gov.uk

The court does not require proof that the council has been involved. The tenant can go directly to court without any prior council inspection or enforcement action. This is the significant procedural difference the Act introduced — it removed the council as a gatekeeper for enforcement.

The landlord's main defences are limited. The Act specifically excludes liability where the unfitness is attributable to the tenant's own behaviour, or where the necessary works require consent from a superior landlord or third party that the landlord has genuinely attempted to obtain. Neither defence applies easily where the landlord has simply failed to respond to reported defects.

Change 1 — Section 21 is gone

Before 1 May 2026, a small number of landlords responded to tenants who would report repairs by serving Section 21 eviction notices on them, instead of making the repair. This led in part to the abolition of Section 21 in the Renters' Rights Act. northtyneside

The retaliatory eviction route is closed. A landlord who receives a fitness complaint and responds by trying to end the tenancy is now exposed to a civil penalty of up to £7,000 for misusing possession grounds as well as the underlying fitness claim. The only legitimate response to a fitness complaint is to investigate and fix the problem.

Change 2 — The HHSRS on-the-spot fines increased to £7,000 per hazard

As covered in the HHSRS edition of this newsletter in June 2026, councils can now issue £7,000 fines per Category 1 hazard on the spot, with escalation to £40,000 for continued non-compliance. The council enforcement route and the tenant court route now operate simultaneously. A landlord facing a fitness claim from a tenant may also face a £7,000 fine from the council for the same hazard — two separate financial consequences from the same defect.

A tenant with a unfit property now has three routes available simultaneously:

Route 1 — Direct court action under the Homes Act
County court claim. Repair order, damages for inconvenience, compensation for damaged belongings, reduced rent for the period of unfitness, and potentially unlimited damages if health has been affected.

Route 2 — Council enforcement under HHSRS
Environmental health inspection. Category 1 hazard triggers a mandatory improvement notice. Non-compliance with the notice: civil penalty up to £30,000 or unlimited fine via magistrates' court. On-the-spot fine of £7,000 per hazard available since 23 June 2026.

Route 3 — Rent Repayment Order
If the landlord has committed a housing offence — including failure to comply with an improvement notice — the tenant can apply to the First-tier Tribunal for repayment of up to 12 months rent. Non-compliance with an Improvement Notice can trigger a civil penalty of up to £30,000 per offence or prosecution in the magistrates' court. The tenant can sue directly under the Homes (Fitness for Human Habitation) Act 2018. Shelter England

These three routes stack. A landlord facing a serious fitness claim can simultaneously be defending a county court action, responding to a council improvement notice, and facing a Rent Repayment Order application — each with its own financial consequences, its own timeline, and its own evidential requirements.

The landlords who face fitness claims are not only those with genuinely bad properties. They are often landlords with reasonable properties who responded slowly to repair reports, kept poor records, or assumed that a verbal assurance to a tenant constituted a repair.

The best protection against fitness claims is a documented maintenance process. That means acknowledging every repair report in writing — even a text acknowledgement creates a dated record. Arranging inspection promptly. Instructing contractors with a written record. Following up to confirm completion. Keeping dated photographs of the property condition at the start of each tenancy and after each significant repair.

Evidence of a proactive, responsive maintenance process is the landlord's strongest position in any fitness dispute. The absence of that evidence — even where the landlord believes they responded reasonably — makes the tenant's case significantly easier to establish.

Every edition of The Landlords Brief connects back to this foundation obligation. The Gas Safety Certificate, the EICR, the EPC, the HHSRS inspection, Awaab's Law, the Decent Homes Standard — all of these sit on top of the baseline requirement that a property is fit for human habitation throughout the tenancy.

A landlord who maintains valid safety certificates, responds promptly to repair reports, documents their maintenance process and keeps their properties free from Category 1 hazards is almost certainly compliant with the Homes Act as well. The fitness obligation is not a separate compliance exercise — it is the foundation that all other housing obligations are built on.

✅ Inspect every property before the tenancy starts — document condition with dated photographs and a signed inventory. Fitness at the start of the tenancy is the first limb of the implied covenant.

✅ Acknowledge every repair report in writing — text, email, letter. The acknowledgement creates a dated record that the report was received. Failure to acknowledge makes it harder to establish when the clock started.

✅ Respond promptly — the court will assess reasonableness. A landlord who inspects within days and instructs a contractor within a week is in a very different position to one who lets three months pass.

✅ Keep contractor records — written instructions, dated completion confirmations, photographs of completed work. Your evidence pack is your defence.

✅ Check occupant vulnerability — the fitness assessment is not one-size-fits-all. A defect that poses a moderate risk to a healthy tenant may pose a serious risk to an elderly, disabled or immunocompromised occupant in the same property.

✅ Never use possession as a response to a repair complaint — retaliatory possession is now a £7,000 civil penalty on top of the underlying claim. The only legitimate response to a fitness complaint is investigation and repair.

✅ Know the three enforcement routes — council HHSRS, direct court claim, Rent Repayment Order. All three can run simultaneously from the same defect.

✅ Connect your safety certificates to the fitness standard — a valid Gas Safety Certificate, EICR and EPC are evidence of proactive maintenance. Letting them lapse is evidence of the opposite.

The Homes (Fitness for Human Habitation) Act 2018 is not a complicated piece of legislation. Its core requirement is simple: keep the property fit throughout the tenancy. What has changed in 2026 is the enforcement landscape around it.

With Section 21 gone, retaliatory eviction is no longer an option. With HHSRS on-the-spot fines increased, council enforcement is faster and more expensive. With Awaab's Law coming and the PRS Database requiring compliance evidence on registration — the fitness obligation is becoming harder to ignore and more expensive to breach.

The landlords who will navigate 2026 and beyond without fitness claims are not those with perfect properties. They are those with documented maintenance processes, prompt repair responses, and evidence files that show a landlord who takes their obligations seriously.

Track repair reports, maintenance records and compliance documents across your entire portfolio — the evidence file you need if a fitness claim ever arrives.
