What does a bathroom extractor fan cost in Hertford?
In Hertford, 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 Hertford
We work right across Hertford — SG13 and SG14 — and in neighbouring Ware and Hoddesdon.
In Hertford, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Hertford bathroom has black mould on the ceiling or silicone, the fan and its duct are the first things we check. We check the duct route at Hertford surveys, because a short, straight run to outside matters more than the fan's headline figure.
Water across much of Hertfordshire is 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
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
Decisions to make first
Axial, centrifugal or inline
Axial fans suit short, straight runs; centrifugal fans cope better with longer ducts; inline fans sit in the loft and are the quietest in the room.
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.
