How we approach extractor fans in Bexley
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.
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.
Inline fans
A quiet fan in the loft serving one or two ceiling grilles in a shower room or en-suite.

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 Bexley
How do I get a price for new extractor fans in Bexley?
Use the guide price tool, the form on this page, live chat, WhatsApp or call 0800 088 6341. A postcode and a couple of photos help us give you a useful answer first time.
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.
