How we approach extractor fans in Swanley
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.

Questions from Swanley
Do you cover Swanley and nearby?
Yes. We cover Swanley and nearby places including Bexley, Chelsfield, Orpington and Sidcup. Send your postcode and we will confirm.
How much does it cost to fit an extractor fan?
Replacing a fan on an existing duct usually costs £175 to £295 including VAT. A new fan through an outside wall is typically £345 to £545, and a fan ducted to outside through the loft £445 to £745.
What size extractor fan does a bathroom need?
In England a bathroom fan should extract at least 15 litres a second, measured at the fan, under Approved Document F. Long or bendy duct runs reduce flow, so the fan often needs to be rated higher than the minimum.
