Extractor fans for Warminster 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.
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 Warminster
Is the survey free in Warminster?
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.
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.
