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 Roehampton
Do you cover Roehampton and nearby?
Yes. We cover Roehampton and nearby places including Putney, East Sheen, Barnes and Mortlake. Send your postcode and we will confirm.
Do you need building regulations for a new extractor fan?
Fitting or replacing an extractor fan has to meet the ventilation and electrical rules, and certain electrical work is notifiable. We do the work to the current standards. Electrical work that is notifiable is certified by a registered electrician, and you get a copy of the certificate and our airflow readings.
How long does fitting a fan take?
A straight replacement takes an hour or two. A new fan with a core-drilled hole or a duct through the loft usually takes half a day.
What is the price of new extractor fans in Roehampton?
Guide prices for Roehampton use London rates: like-for-like extractor fan replacement (existing duct and wiring) is typically £210 to £355 inc VAT per fan. We confirm a fixed price in writing before any work starts.
