Fitness for Human Habitation Act 2018: How Tenants Can Claim

The Act amends the Landlord and Tenant Act 1985 to create an implied term in every tenancy agreement in England. Your landlord must ensure the property is fit for human habitation at the start of the tenancy and remains fit throughout. This applies regardless of how you pay rent, and it covers both private landlords and social housing providers.

A property is "unfit" if defects make it not reasonably suitable for occupation, having regard to the condition and character of similar properties in the area. Courts look at a checklist of matters including: structural instability, dampness, natural lighting, ventilation, water supply, drainage, cooking facilities, and fire safety. If any combination of these creates a health or safety risk, the threshold may be met.

One specific point matters a lot in practice: courts assess unfitness based on the actual tenant's circumstances, not a hypothetical vulnerable occupant. If you have a young child and there is lead paint peeling in the kitchen, that context is relevant. This differs from how local councils assess properties under the Housing Health and Safety Rating System (HHSRS), which uses a notional vulnerable person as its benchmark.

Landlords cannot contract out of this obligation. Any clause in your tenancy agreement that tries to waive it is unenforceable. The law is clear on this, and it applies automatically to your tenancy without you needing to negotiate it in.

Mould and damp are the most common triggers. The English Housing Survey 2024-25 found that 9% of dwellings, around 2.3 million homes, still contained a Category 1 hazard under HHSRS. That is the kind of hazard the Act is designed to address.

Beyond mould, the following have been accepted in claims:

• Structural instability: cracks in load-bearing walls, subsidence, collapsing ceilings
• Inadequate heating: no central heating, a broken boiler left unrepaired for weeks
• Fire safety failures: missing smoke alarms, blocked escape routes, faulty electrics
• Pest infestations: mice, cockroaches, or rats that the landlord has not addressed
• Sewage or drainage problems: blocked drains backing up into the property
• Lack of clean water supply: broken pipes, contamination

Defects that are cosmetic or minor inconveniences generally do not meet the threshold. A dripping tap or a scuffed wall does not make a property unfit. The question is whether the defect creates a real risk to health or safety.

The Act also covers situations where the property was unfit at the start of the tenancy, even if the defect was not visible. If a competent inspection at the point of letting would have identified the problem, the landlord is on the hook. You do not need to prove they knew about it. You need to prove it existed and posed a risk.

This is where renters get confused, and it matters.

A traditional housing disrepair claim relies on common law obligations under Section 11 of the Landlord and Tenant Act 1985, which covers repairs to the structure, exterior, and installations. The Housing Disrepair Protocol sets out a formal pre-action procedure: you send a letter before claim, the landlord has time to inspect and respond, and both parties exchange expert reports before anything goes to court.

The Homes (Fitness for Human Habitation) Act 2018 is different in two ways. First, it covers a broader range of hazards. A property can have a working boiler and intact walls and still be unfit if severe mould has rendered a bedroom unusable. Second, and more usefully for tenants, the standard is fitness for the actual occupant, not just structural adequacy.

In practice, most solicitors run both claims together because they overlap considerably. If your landlord has failed to repair a structural defect and that failure has made the property unfit, you have arguments under Section 11 and Section 9A at the same time.

One important procedural note: while the Act does not technically require you to give formal notice before suing, courts expect it. Send a written complaint, describe the defect clearly, and give a reasonable timeframe for a response, typically 14 to 28 days for urgent issues. If you skip this step, a judge may penalise you on costs even if you win.

For the full procedural picture, our housing disrepair protocol UK tenant guide covers the pre-action steps in detail.

Courts award two main types of remedy under the Act: an injunction forcing the landlord to carry out repairs, and damages for the period the property was unfit.

Damages are calculated as a percentage of rent for the period of unfitness, based on how severely the defects affected your enjoyment of the property. In 2024, one judge awarded damages equivalent to a 90% rent reduction for a property deemed unfit throughout the tenancy (Smith v Jones, County Court, 2024). That figure is at the extreme end, reserved for properties that are practically uninhabitable. Typical awards range from 25% to 50% of rent for the affected period.

To illustrate what that means in practice: if your rent is £1,400 per month and your property had severe mould in two rooms for 12 months, a 40% reduction would produce a damages award of £6,720. That is not a small sum.

You can also recover consequential losses, including the cost of alternative accommodation if you had to leave temporarily, damage to personal belongings caused by the disrepair, and medical costs directly attributable to the condition of the property.

Between 2020 and 2024, housing disrepair claims against councils rose by 392%, with related legal costs increasing by 428% over the same period (Local Government Association, 2024). Courts are awarding real money, and the precedents are moving in tenants' favour.

For claims under £10,000 in total value, the Small Claims track in the County Court is available. You can represent yourself, and costs are limited, which reduces risk.

Document everything before you do anything else. Take dated photographs and video of every defect. Keep a written diary of when you reported problems, what you said, and what response you received. Save every text, email, and WhatsApp message.

Then contact your local council's environmental health department. They will inspect for free and can issue an improvement notice if they identify a Category 1 or Category 2 hazard. That notice is strong legal evidence because it is an independent, official assessment. If your landlord ignores it, they are now ignoring both a contractual obligation and a statutory notice.

Send a formal letter before claim. This should describe the defects, reference the Homes (Fitness for Human Habitation) Act 2018, state that the property is unfit, and give a deadline for the landlord to respond and commit to a repair schedule. 14 days is a reasonable deadline for urgent issues. Keep a copy and send it by recorded post or email so you have proof of delivery.

If the landlord does not respond or refuses to act, you have two options: issue proceedings in the County Court yourself, or instruct a no-win no-fee solicitor. Many solicitors handle these claims under a Conditional Fee Agreement, typically taking around 25% of the damages award.

For claims where the primary issue is mould, see our guide on mould and damp landlord obligations and tenant claims for specific advice on that category.

Remedy can help you build your claim before it reaches that point. Start with a free instant assessment of your situation, and Remedy will tell you whether the Act applies, what your case is worth, and what to do next. The platform can also draft the letter before claim on your behalf, referencing the relevant legislation, so you do not have to figure out the wording yourself.

Once you assert your rights under the Act, your landlord cannot lawfully evict you in retaliation. The Renters' Rights Act 2025 significantly limits the ability to use Section 21 notices, and Section 21 will be abolished entirely on 1 May 2026. Any eviction notice served shortly after you make a disrepair complaint is a red flag and may constitute retaliatory eviction.

Under current law, if your landlord serves a Section 21 notice within six months of you making a formal written complaint about the condition of the property to the local authority, that notice is invalid. Courts treat this seriously. For a full breakdown of your protections in this scenario, see our article on landlord retaliation eviction UK tenant rights.

Landlords also cannot lawfully enter the property without proper notice to inspect or carry out repairs. Entry without your permission, except in genuine emergency, is a separate legal issue. If a landlord is using inspection visits as pressure after you raise a claim, that behaviour has its own legal consequences.

If you receive a Section 8 notice after raising a fitness for human habitation claim, do not ignore it. Respond in writing, note the timing relative to your complaint, and take legal advice. Remedy's section 8 eviction defence UK tenant guide covers how to respond.

The Housing Ombudsman found maladministration in 72% of cases it reviewed in Q2 2025/26, with 44% resulting in compensation orders (Housing Ombudsman Service, 2025). Landlords who ignore disrepair complaints are losing. The data is not ambiguous.
