How we approach extractor fans in Sutton

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

Questions from Sutton

Do you cover Sutton and nearby?

Yes. We cover Sutton and nearby places including Belmont, Cheam, Carshalton and Banstead. Send your postcode and we will confirm.

Should I get a fan with a humidity sensor?

A humidistat fan switches on when the air gets damp and runs until it clears, which suits family bathrooms and rentals where people forget the switch. A continuous-running fan is another good option.

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.

What is the price of new extractor fans in Sutton?

Guide prices for Sutton 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.

Is the survey free in Sutton?

For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.
