Extractor fans for King's Cross 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.

Questions from King's Cross
Do you cover King's Cross and nearby?
Yes. We cover King's Cross and nearby places including Barnsbury, Holborn, Islington and Camden Town. Send your postcode and we will confirm.
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.
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.
What is the price of new extractor fans in King's Cross?
Guide prices for King's Cross use London rates: like-for-like extractor fan replacement (existing duct and wiring) is typically £210 to £355 inc VAT per fan. We confirm a fixed price in writing before any work starts.
