What does a bathroom extractor fan cost in Formby?
As a guide, budget £235 to £550 including VAT for a bathroom extractor fan in Formby; your written quote will pin it down.

Working in Formby
We cover every part of Formby, including L37 and L38, and nearby Maghull (6 miles) and Southport (6.5 miles).
Being a smaller town does not change how we work in Formby: free survey, written quote, one team. If your Formby 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 Formby surveys, because a short, straight run to outside matters more than the fan's headline figure.
Supplies across most of Merseyside are soft. Even so, condensation is the bigger problem in any bathroom, and a properly sized extractor is what deals with it. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Wiring by a qualified electrician, with an isolator outside the room and RCD protection
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
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.
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.
