Rules that apply in Wales
In Wales, ventilation follows the Welsh Approved Document F rather than the English version, with building control checking notifiable work. Rented homes in Wales must be fit for human habitation under the Renting Homes (Wales) Act, and damp and mould is one of the matters considered.
