How we approach extractor fans in Southampton
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.
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.

Rules that apply in England
In England, ventilation is covered by Part F of the Building Regulations and its guidance, Approved Document F (2021 edition). For homes, it sets minimum extract rates such as 15 litres a second for a bathroom and 30 or 60 for a kitchen, and expects mechanical systems to be airflow-tested.
Questions from Southampton
Do you cover Southampton and nearby?
Yes. We cover Southampton and nearby places including Woolston, Portswood, Hythe and Totton. 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 Southampton?
Guide prices for Southampton 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.
