If the bathroom mirror in your Barnet home stays steamed up, the fan probably is not moving enough air.

What the work involves
For England, Approved Document F gives minimum intermittent extract rates: 15 litres a second for a bathroom, 30 for a kitchen with a cooker hood (60 without one), 30 for a utility room and 6 for a WC. Wales, Scotland and Northern Ireland have their own rules, which we follow where the job is.
New fan through an outside wall
Core drilled, sleeved, wired from a fused spur and sealed outside.
Ducted to outside through the loft
Insulated duct to a roof, ridge or soffit outlet so warm moist air does not condense in the loft.

Do you need building regulations for a new extractor fan?
Fitting or replacing an extractor fan has to meet the ventilation and electrical rules, and certain electrical work is notifiable. We do the work to the current standards. Electrical work that is notifiable is certified by a registered electrician, and you get a copy of the certificate and our airflow readings.

A straight replacement takes an hour or two. A new fan with a core-drilled hole or a duct through the loft usually takes half a day.
