What does a bathroom extractor fan cost in Cowley?
As a guide, budget £280 to £650 including VAT for a bathroom extractor fan in Cowley; your written quote will pin it down. We adjust the national guide for South East England, where prices are typically about 12% above the UK average. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Cowley
As well as Cowley itself (OX1, OX3 and OX4), we survey in Oxford, Abingdon and Didcot.
Cowley gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We check the duct route at Cowley surveys, because a short, straight run to outside matters more than the fan's headline figure. In Cowley flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.
Water across much of Oxfordshire is hard. Steam carries that scale onto mirrors and glass, so a fan that clears the room quickly helps on both counts. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A backdraught shutter and external grille, so cold air does not blow back in
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
Decisions to make first
Timer or humidistat
A timer keeps the fan running after the light goes off. A humidistat starts it whenever moisture rises, which suits rooms where people forget.
Replacement air
A fan needs air to replace what it removes, so leave a gap of around 10 mm under the door or fit a door grille. A sealed room starves the fan.
Rules that apply in England
In England, Approved Document F sets bathroom extract at 15 l/s for an intermittent fan or 8 l/s for continuous extract. Wiring a new fan alters a circuit in a room with a bath or shower, so it is notifiable under Part P.
