Extractor fans for Carshalton 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.
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.
Inline fans
A quiet fan in the loft serving one or two ceiling grilles in a shower room or en-suite.

Rules that apply in England
English building work follows Approved Document F (2021 edition) for ventilation rates, installation and commissioning. 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 Carshalton
How do I get a price for new extractor fans in Carshalton?
Use the guide price tool, the form on this page, live chat, WhatsApp or call 0800 088 6341. A postcode and a couple of photos help us give you a useful answer first time.
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.
