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.
New fan through an outside wall
Core drilled, sleeved, wired from a fused spur and sealed outside.
Ducted to outside through the loft
Insulated duct to a roof, ridge or soffit outlet so warm moist air does not condense in the loft.

Questions from Portsmouth
Do you cover Portsmouth and nearby?
Yes. We cover Portsmouth and nearby places including Southsea, Gosport, Cosham and South Hayling. 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 Portsmouth?
Guide prices for Portsmouth 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.
