What does a bathroom extractor fan cost in Bushey?
In Bushey, a bathroom extractor fan typically costs £265–£650 including VAT, based on East of England prices. Prices in East of England run at about 6% 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 Bushey
In Bushey we cover WD1, WD19 and WD23; we also cover Watford, 1.7 miles away, and North Watford.
Homes in and around Bushey vary, so we look at the floor, the walls and the water system before we price anything. In Bushey flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. If your Bushey bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check.
Supplies across most of Hertfordshire are very 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
Decisions to make first
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.
Wall or ceiling
A wall fan on an outside wall is the simplest. A ceiling fan over the shower takes steam away at source but needs ducting through the loft.
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.
