What the work involves
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. Wales, Scotland and Northern Ireland have their own rules, which we follow where the job is.
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 East Dereham
What is the price of new extractor fans in East Dereham?
Guide prices for East Dereham 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.
How much does it cost to fit an extractor fan?

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.
