Bathroom Extractor Fans – Prices and Options

Electric extractor fans are used to remove damp moist air from bath and shower rooms.

They are often found in bathrooms that were don’t have any windows, but many homeowners choose to install one, even if they have a window.

Extractor fans can prevent mould and bad odours from persisting in the room.

On this page, you’ll see how much it typically costs to replace an existing fan on a like-for-like basis. We’ll also tell you how much a newly installed fan should cost.

We can also provide you with a written quote for an extractor fan for your property.

Extractor Fan Installation Cost Guide (Updated For 2018)

In 2016 we contacted dozens of electricians and asked them to give us a quote for the installation of a new extractor fan.

In March 2018 we repeated the process and updated the prices that you’ll see further down this page.

You can use our price list as a guide to the prices currently being charged for this type of work.

Project 1 – Swap an Extractor Fan Like-for-Like

Extractor fan cost

Swapping an existing fan for a new one on a like-for-like basis is a simple and quick task, one that could even be completed by a competent DIYer.

The prices shown below are an average of the prices we gathered from dozens of tradespeople:

Project 2 – Cost to Install a New Extractor Fan (in a new location)

The second quote we requested from our selected electricians was for a more complicated project – To install an extractor fan for the first time.

This project involves much more work and costs more:

  • Supply and install all the wiring so the extractor fan activates when the bathroom light is activated.
  • Cut through the wall and install ducting to the outside of the wall where there will be a new exhaust grille.
  • Bury the wiring into the wall and plaster over it.
  • The fan will have a sensor that detects when the moisture from the room has been removed and automatically switches itself off.

While this price is to fit an extractor fan onto a wall, we expect it to cost the same or nearly the same as a ceiling fan with ducting through the ceiling and in the loft space.

Because electrical work in a bathroom has the potential to be dangerous, the work should be done by a tradesperson who can “self-certify” their work OR Building Control will need to be notified of the work details.

Options – Three Types of Bathroom Extractor Fan

There are three ways to remove the moisture from a bathroom:

  1. The most popular option is to install a fan on the ceiling and to duct the moisture out of the roof eaves via the loft space.
  2. Wall mounted fans are often used when the home doesn’t have an accessible loft space.
  3. Window mounted fans are less common these days, the glass needs to be cut and most homeowners are uneasy at the thought of cutting through new double or even triple glazed windows.

Unit Cost

A good quality bathroom extractor fan will cost between £75 – £100, at this price range you can expect the unit to be powerful, yet run silently and efficiently.

There are plenty of units in the £20-£40 range but these are often noisy and less powerful.

We feel it’s worth paying a little extra for the fan and getting a good quality one that will last for years.

Best Place to Buy a Fan

Victoria Plum have a good range of extractor fans, as does the online retailer Amazon.

Most Common Reasons Why Consumers Install Bathroom Fans

Excessive levels of moisture and condensation in the home can cause all sorts of problems:

  • Damp spots on walls and ceilings
  • Bad odours
  • Condensation on walls and windows
  • Black mould on bath and showers

If a bathroom doesn’t have a window then it must have an extractor fan and preferably one with a sensor that only switches the device off when the room is dry.

Landlords often install these fans if they’re concerned their tenants may not open the window to vent the moisture.

If you already have a fan installed but it’s not powerful enough to remove the moisture, you can swap it for a more powerful unit on a like-for-like basis.

    Hi….I am looking to replace my extractor fan in the bathroom via a ceiling vent into the roof…there has been an issue in the past where moisture has managed to drip into the fan and caused the fan to stop working…looking for a competitive quote to replace. Thanks
