How we approach extractor fans in Greenwich

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.

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.

How much does it cost to fit an extractor fan?
