What does a bathroom extractor fan cost in Lewes?
As a guide, budget £280 to £650 including VAT for a bathroom extractor fan in Lewes; 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 Lewes
We cover every part of Lewes, including BN7, and nearby Rottingdean (5.3 miles) and Peacehaven (5.7 miles).
Being a smaller town does not change how we work in Lewes: free survey, written quote, one team. If your Lewes 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 Lewes bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Supplies across most of East Sussex 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
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Making good around the fan and checking that it extracts properly at the grille
- A check of the room, any existing fan or vent, and the shortest route to the outside
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.
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.
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.
