What does a bathroom extractor fan cost in Gosport?
In Gosport, a bathroom extractor fan typically costs £280–£650 including VAT, based on South East England prices. 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 Gosport
We cover every part of Gosport, including PO12 and PO13, and nearby Portsmouth (1.7 miles) and Southsea (1.9 miles).
Gosport has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. If your Gosport 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. Fans fitted in Gosport bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Supplies across most of Hampshire are 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
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- 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
- 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.
Noise
Compare the stated noise level in decibels. Inline fans and low-speed continuous fans are much quieter in the room than budget axial fans.
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.
