How we approach extractor fans in Totteridge
The rate a fan delivers through a real duct run is often far lower than the number on the box, which is why we size to the room and test the result. 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.
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.

Rules that apply in England
In England, ventilation is covered by Part F of the Building Regulations and its guidance, Approved Document F (2021 edition). For homes, it sets minimum extract rates such as 15 litres a second for a bathroom and 30 or 60 for a kitchen, and expects mechanical systems to be airflow-tested.
Questions from Totteridge
What area around Totteridge do you work in?
All of Greater London. Near Totteridge that includes Barnet, New Barnet, East Barnet and Finchley.
Should I get a fan with a humidity sensor?
A humidistat fan switches on when the air gets damp and runs until it clears, which suits family bathrooms and rentals where people forget the switch. A continuous-running fan is another good option.
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.
