What extractor fan installation involves

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. 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.

New fan through an outside wall

Core drilled, sleeved, wired from a fused spur and sealed outside.

Rules 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 about extractor fan installation in Oxfordshire

Which towns in Oxfordshire do you cover?

All of Oxfordshire, including Witney, Cowley, Carterton, Oxford and Banbury. If your town is not listed, send the 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.

Are prices different in Oxfordshire?

Our guide prices are adjusted by region. In Oxfordshire we use South East rates, so like-for-like extractor fan replacement (existing duct and wiring) is typically £195 to £325 inc VAT per fan.

Is the survey free in Oxfordshire?

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.

Book an Oxfordshire visit and we will test the fan you have before recommending a new one.
