Extractor fans for Gerrards Cross homes

Many existing fans were never doing their job: undersized, ducted into the loft space, fitted with a flex duct crushed in the joists, or switched off by occupants because they were noisy. 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.

Inline fans

A quiet fan in the loft serving one or two ceiling grilles in a shower room or en-suite.

Kitchen extract and cooker hoods

A wall or window fan, or a cooker hood ducted outside rather than recirculating.

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 Gerrards Cross

Do you cover Gerrards Cross and nearby?

Yes. We cover Gerrards Cross and nearby places including Chalfont St Peter, Uxbridge, Beaconsfield and Rickmansworth. Send your postcode and we will confirm.

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.
