Questions about ventilation for landlords and letting agents in Clwyd
Which rules apply to ventilation in Clwyd?
In Wales, the Welsh Government's own Approved Document F (2022 edition) applies to ventilation in homes, with a new edition taking effect on 4 March 2027. Rented homes must be fit for human habitation under the Renting Homes (Wales) Act 2016, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
Do you give landlords paperwork?
Every job comes with photos, product details and measured airflow, so you can show what was done and when.
Is a landlord responsible for condensation and mould?
A landlord is responsible for the condition of the property, including adequate ventilation and heating, and serious damp and mould can be a hazard under housing law. Tenants also have to use the home reasonably, but ventilation that works without effort removes most disputes.
