Extractor fans
A bathroom or kitchen fan needs two things: a power supply and a route outside for the air, through a wall, window or roof. Replacing an existing fan on the same vent is usually quicker than fitting a new one, because the hole and the wiring are already there.
The type of fan affects the work. A wall fan straight through an outside wall is the simplest. An inline fan in the loft, ducted to a grille in the ceiling and out through the roof or eaves, suits rooms without an outside wall. Some fans come on with the light and run on for a few minutes afterwards. Others have a humidity sensor or a separate pull cord.
In a bathroom, any addition or alteration to a circuit within the zone around the bath or shower is notifiable under the Building Regulations. Fans in that zone also need the right protection rating for where they sit. If the work is notifiable, it should be certified by an electrician registered with a competent person scheme or signed off through building control.
A new hole through a solid wall usually needs a core drill. Some electricians do this themselves and some bring in a builder. In a listed building or a conservation area, check with your local council before cutting a new hole in an outside wall.
What to include when you post
Photos save a lot of back and forth on fan jobs.
- Which room it’s for: bathroom, shower room, en suite, kitchen or utility.
- Whether it replaces an old fan, with a photo of the existing one.
- Whether there’s an existing vent to the outside.
- A photo of the wall or ceiling where you want it, and the outside wall if you can.
- Whether there’s a loft space above.
- How you’d like it to switch on: with the light, a pull cord or a humidity sensor.
- Whether you’ve already bought a fan, and the make and model if so.
- If it’s a listed building or in a conservation area.
What to ask
Ask whether the job is notifiable and, if so, whether they are registered with a competent person scheme. Work in the zone around a bath or shower is notifiable, and a new circuit always is.
A written quote should say:
- which fan is included, or that you’re supplying it
- whether the vent hole, core drilling, ducting and outside grille are included
- how it will be switched and whether it has a run-on timer
- whether filling and making good around the fan and the cable route is included
- what certificate you’ll get
- that the old fan will be taken away
If a builder is needed for the hole, find out who is organising them and whether their cost is in the quote.

Questions
What people tend to ask before booking this job. For anything specific to your home, ask the tradesperson who takes it on when they get in touch.
If there is no existing vent, the fan needs a route outside. The electrician may bring in a builder for a core drill through a solid wall.
Many can be wired to come on with the light and run on for a few minutes after it's switched off. Say if you want that, as it affects the wiring.
Sometimes a clean or a new motor is enough, but a like-for-like replacement is often simpler. It's also worth checking that the duct isn't blocked, crushed or too long for the fan.
If the work is in the zone around the bath or shower, or involves a new circuit, it's notifiable and must be certified by a registered electrician or through building control. Otherwise you should still get a certificate for the electrical work.
A window helps, but a fan clears steam faster and works when the window is shut in winter. For new or refitted bathrooms and kitchens, ask the electrician what extraction the Building Regulations call for.
