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.
Like-for-like replacement
A new fan on the existing duct and wiring, often with an overrun timer or humidity sensor.
New fan through an outside wall
Core drilled, sleeved, wired from a fused spur and sealed outside.

Rules that apply in England

Questions from Bayswater
Do you cover Bayswater and nearby?
Yes. We cover Bayswater and nearby places including Lancaster Gate, Hyde Park, Westbourne and Little Venice. Send your postcode and we will confirm.
How much does it cost to fit an extractor fan?
Replacing a fan on an existing duct usually costs £175 to £295 including VAT. A new fan through an outside wall is typically £345 to £545, and a fan ducted to outside through the loft £445 to £745.
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.
