Extractor fans for Redhill 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.
Inline fans
A quiet fan in the loft serving one or two ceiling grilles in a shower room or en-suite.
Kitchen extract and cooker hoods
A wall or window fan, or a cooker hood ducted outside rather than recirculating.

Questions from Redhill
What is the price of new extractor fans in Redhill?
Guide prices for Redhill 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.
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.
Is the survey free in Redhill?
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.
