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.
Kitchen extract and cooker hoods
A wall or window fan, or a cooker hood ducted outside rather than recirculating.
Like-for-like replacement
A new fan on the existing duct and wiring, often with an overrun timer or humidity sensor.

Questions from Abbots Langley
How do I get a price for new extractor fans in Abbots Langley?
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.
