Questions about ventilation repairs and fault finding in South Glamorgan
Is the survey free in South Glamorgan?
This is a charged visit because it is servicing, testing or repair work. We tell you the cost before booking. Surveys for new installations on the UK mainland are free.
Can you repair any make?
We repair most common makes. If parts are unavailable we will tell you before the visit and suggest options.
Can you come out urgently?
We cannot promise an out-of-hours or same-week visit. We try to fit in failed kitchen extract and commercial plant first, so ask about the earliest available visit when you call.
Which rules apply to ventilation in South Glamorgan?
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.
