Wales holds residential landlords to some of the highest, most rigorously enforced safety and maintenance standards in the United Kingdom.

Under the Renting Homes (Wales) Act 2016, a landlord is legally required to ensure their property is Fit for Human Habitation (FFHH). This goes far beyond fixing a leaky faucet; it requires strict adherence to mandatory safety certifications.

1. The Mandatory FFHH Requirements

For a Welsh property to be legally defined as Fit for Human Habitation, the landlord must possess and supply the contract-holder with valid evidence of three core safety elements.

If any of these three are missing, the property is legally deemed "unfit." If a property is unfit, the contract-holder is legally not required to pay rent for the duration of the unfitness, and the landlord is banned from issuing an eviction notice.

A. Electrical Safety (EICR)

The landlord must have an Electrical Installation Condition Report (EICR) carried out by a qualified electrician at least once every 5 years. A copy of this certificate must be provided to the contract-holder within 14 days of them moving in.

B. Gas Safety Certificates

If the property contains gas appliances (boilers, hobs, fires), a registered Gas Safe engineer must perform a safety check annually. A copy of the valid certificate must be provided within 14 days of move-in, and within 28 days of every subsequent annual check.

C. Working Alarms

• Smoke Alarms: A functioning smoke alarm must be installed on every storey of the dwelling. (For contracts signed after Dec 2022, these must be hard-wired or run on specialized sealed 10-year batteries and be interlinked).
• Carbon Monoxide Alarms: A functioning carbon monoxide alarm must be present in every room containing a gas, oil, or solid fuel burning appliance.

2. General Repair Obligations

In addition to the mandatory FFHH safety checks, the landlord's general repair obligations are enshrined as "Fundamental Terms" in every Welsh Written Statement (meaning landlords cannot contract out of them).

The landlord must:

• Keep the structure and exterior of the dwelling in repair (the roof, walls, windows, and foundation).
• Keep installations for the supply of water, gas, electricity, and sanitation functioning properly (pipes, toilets, sinks, wiring).
• Keep installations for space heating and water heating (boilers) in repair and proper working order.

The landlord has a "reasonable time" to execute a repair once they have been formally notified of the defect by the contract-holder. What is deemed "reasonable" depends entirely on the severity of the issue (e.g., a burst pipe flooding the kitchen requires action in hours; a cracked bedroom window may allow weeks).

The Contract-Holder's Obligations

While the landlord handles major repairs and safety testing, the contract-holder's obligations are outlined in the Supplementary Terms of the occupation contract.

Contract-holders must:

• Act as a "prudent steward," meaning taking sensible care of the property, keeping it clean, and ensuring proper ventilation to prevent mold built up from drying clothes indoors.
• Perform very minor, everyday maintenance (e.g., unblocking a hair-clogged shower drain or changing lightbulbs securely).
• Pay to repair any damage caused directly by their own negligence or the negligence of their guests.

The Right to Claim Rent Repayment

Wales enforces maintenance obligations through financial pain. If a landlord ignores requests to fix a major defect that renders the property unfit (e.g., leaving a family without heating in winter for weeks, or failing to renew an EICR), the contract-holder can apply to the County Court. The judge can order the landlord to repay rent that was collected during the period the property was legally unfit.
