Wales Landlord Repairs and Maintenance Obligations Under the Renting Homes Act

Most Welsh landlords know they need to fix things when they break. Fewer realise that since 1 December 2022, the Renting Homes (Wales) Act 2016 imposes two separate statutory duties that go well beyond reactive repairs. Rent is not payable for days the dwelling is legally unfit; a repair failure that does not make the dwelling unfit does not by itself suspend rent.

Section 91 vs Section 92: Two Distinct Duties

Section 91 requires that the dwelling is fit for human habitation at the start of every occupation contract and throughout its duration. This is an absolute obligation — a contract-holder does not need to report a defect before you become liable.

Section 92 covers structural and service repairs: the roof, exterior walls, drains, gutters, external pipes, and all installations for water, gas, electricity, sanitation, and heating. This duty applies once you know (or ought to know) about the defect.

The practical difference matters. A slow leak behind a kitchen wall does not trigger the Section 92 repair duty until you know, or ought to know, about it. But if that leak has caused visible damp and mould that makes the property unfit, Section 91 may already be breached — and rent is not payable for the period the dwelling is legally unfit, regardless of whether anyone told you.

Dampness and Ventilation

Damp and mould is the single most common fitness complaint in Welsh rental properties. Under Matter 1 of the Renting Homes (Fitness for Human Habitation) (Wales) Regulations 2022 (S.I. 2022/6), exposure to moisture, fungal growth, or house dust mites is a prescribed hazard.

Warning signs include black mould (particularly Stachybotrys), tidemarks on walls, peeling wallpaper, and persistent musty odour. Surface moisture readings above 20% WME indicate a structural moisture problem that simple ventilation will not resolve.

Ventilation is not just good practice — inadequate ventilation contributes to both Matter 1 (damp and mould) and Matter 3 (excess heat). You must ensure that habitable rooms have operable windows or mechanical extraction, and that kitchens and bathrooms have extraction adequate to prevent condensation build-up.

What counts as adequate? There is no single Welsh statutory ventilation rate for private lettings, but Building Regulations Approved Document F (which applies to new installations and replacements) sets the benchmark: intermittent extraction of 30 l/s in kitchens and 15 l/s in bathrooms. An electrician installing a new extractor fan should meet these rates as standard.

Structural Repairs and the Exterior

Section 92 covers the structure and exterior of the dwelling, including:

• Roof, chimneys, and flashings
• External walls, pointing, and render
• Window frames, sills, and glazing
• External doors and door frames
• Drains, gutters, downpipes, and external pipework
• Boundary walls and fences (where part of the building structure)

You do not need to improve the property beyond its condition at the start of the contract. But you must maintain it — and "maintain" means keeping it in the state of repair appropriate to its age, character, and prospective life. A Victorian terrace does not need double-glazed sash windows, but it does need sash windows that open, close, and keep rain out.

Service Installations

All fixed installations for water supply, gas, electricity, sanitation, space heating, and water heating fall under Section 92. This includes:

• The boiler and central heating system
• Hot water cylinders and immersion heaters
• Fixed electrical wiring and consumer units
• Soil stacks, waste pipes, and drainage traps
• Cold and hot water supply pipework

When an installation fails, you must repair or replace it within a reasonable time. What counts as reasonable depends on the severity: a total heating failure in January requires emergency-speed response; a dripping mixer tap does not. But leaving a dripping tap for months until it causes water damage crosses into Section 91 territory.

The 24-Hour Access Rule

Under Section 98, you have a statutory right to enter the dwelling to inspect its condition or carry out repairs — but you must give the contract-holder at least 24 hours' written notice. Emergency entry (active gas leak, flooding, structural collapse) is the only exception.

If a contract-holder refuses access after proper notice, you cannot force entry or change locks. The lawful route is a County Court application for an injunction. Document every access request, every refusal, and every piece of correspondence — this audit trail protects you if a disrepair claim later argues you failed to act.

Protecting Yourself With Records

The difference between a compliant landlord and one facing a rent withholding claim often comes down to paperwork. Keep dated records of:

• Every maintenance request received, with the date and method of reporting
• Every contractor quote, appointment, and completion certificate
• Every written notice of access
• Photographs of the property condition at check-in and after repairs

What Happens When You Breach

For each day a dwelling is unfit under Section 91, the contract-holder is not liable for rent. A Rent Repayment Order is a separate remedy for qualifying offences such as unlicensed letting or management; it is not available solely because of disrepair or unfitness. An occupier's application under HMO or selective licensing law requires a qualifying conviction or prior qualifying order, and up to 12 months' rent may be in scope.

Local authority environmental health officers can serve Improvement Notices under the Housing Act 2004. Rent Smart Wales may issue a £150 fixed penalty for a registration offence or a £250 fixed penalty for an unlicensed letting or management offence.

The most effective protection is not waiting for complaints. A structured self-inspection covering the 29 statutory hazard categories, combined with timely professional inspections (EICR, gas safety, EPC), catches problems before they become legal liabilities.
