Every occupation contract in Wales carries an implied term that the dwelling is fit for human habitation, under sections 91 and 94 of the Renting Homes (Wales) Act 2016. Not a duty you can contract out of, and not a standard the contract-holder has to invoke — it is a term of the contract itself.
The 29 matters
The Renting Homes (Fitness for Human Habitation) (Wales) Regulations 2022 set out 29 matters and circumstances to which regard must be had in deciding fitness. They track the Housing Health and Safety Rating System hazards familiar from England — damp and mould, excess cold, fire, electrical hazards, falls, overcrowding — but here they are wired into the contract rather than into an enforcement regime.
The practical difference: in England the HHSRS is something a council applies to you. In Wales the same subject matter is a term the contract-holder can enforce directly.
The two conditions that catch landlords out
The 2022 Regulations also make two specific requirements conditions of fitness. Fail either and the dwelling is unfit as a matter of law, whatever else is true of it:
1. Working smoke and carbon monoxide alarms
Smoke alarms on each storey, mains-wired and interlinked, and a carbon monoxide alarm in each room with a gas, oil or solid fuel appliance.
2. A valid electrical condition report
An EICR carried out at least every five years, with a copy provided to the contract-holder.
This is the route Wales used, and it is worth understanding. England imposed electrical safety and alarms through standalone regulations enforced by the council with civil penalties — £30,000 for the EICR, £5,000 for alarms. Wales reached the same requirements by making them conditions of fitness, so the consequence is not primarily a penalty but that the dwelling is unfit.
Same destination, different machinery. And the Welsh machinery has a sharper edge: an unfit dwelling means a contract-holder claim, and it blocks a section 173 notice.
