How we approach extractor fans in Chelsfield
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 Chelsfield
What is the price of new extractor fans in Chelsfield?
Guide prices for Chelsfield use South East rates: like-for-like extractor fan replacement (existing duct and wiring) is typically £195 to £325 inc VAT per fan. We confirm a fixed price in writing before any work starts.
Can an extractor fan vent into the loft?
No. A fan should discharge to outside, because warm, moist air dumped in the loft condenses on the cold roof timbers and causes mould and rot there instead.
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.
Is the survey free in Chelsfield?
For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.
