How we approach extractor fans in Diss
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.
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 Diss
Do you cover Diss and nearby?
Yes. We cover Diss and nearby places including Attleborough, Stowmarket, Thetford and Bowthorpe. 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 Diss?
Guide prices for Diss use East of England rates: like-for-like extractor fan replacement (existing duct and wiring) is typically £185 to £310 inc VAT per fan. We confirm a fixed price in writing before any work starts.
