Questions about ventilation for landlords and letting agents in Gwynedd and Anglesey

Is the survey free in Gwynedd and Anglesey?

For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.

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.

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.
