How we approach extractor fans in Amesbury
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.
Kitchen extract and cooker hoods
A wall or window fan, or a cooker hood ducted outside rather than recirculating.
Like-for-like replacement
A new fan on the existing duct and wiring, often with an overrun timer or humidity sensor.

Questions from Amesbury
What area around Amesbury do you work in?
All of Wiltshire. Near Amesbury that includes Tidworth, Salisbury, Andover and Devizes.
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.
