What does a bathroom extractor fan cost in Witney?
For Witney, our guide range for a bathroom extractor fan is £280 to £650 including VAT. Prices in South East England run at about 12% above the national guide, mainly because of labour rates. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Witney
As well as Witney itself (OX28), we survey in Carterton, Oxford and Abingdon.
In Witney, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Witney home is listed or in a period terrace, a fan ducted through the loft to a roof vent can avoid a new hole in the front wall, though consent may still apply. In Witney 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 check of the room, any existing fan or vent, and the shortest route to the outside
- A backdraught shutter and external grille, so cold air does not blow back in
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Making good around the fan and checking that it extracts properly at the grille
Decisions to make first
Intermittent or continuous
An intermittent fan runs during and after use. A continuous fan runs quietly all the time at a low rate and boosts when humidity rises.
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.
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.
