Extractor fans for Hanworth 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.
Like-for-like replacement
A new fan on the existing duct and wiring, often with an overrun timer or humidity sensor.
New fan through an outside wall
Core drilled, sleeved, wired from a fused spur and sealed outside.

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.
