Best Bathroom Extractor Fans for UK Homes 2026
Updated June 2026
A bathroom without proper extraction is a mould factory. Every shower pumps litres of moisture into a small enclosed space. Without an extractor fan pulling that moisture out, it condenses on walls, ceilings and windows — and within weeks, you have black mould. The good news: a decent bathroom extractor fan costs £20–£60, fits standard UK 100mm ducting, and most homeowners can install one in under an hour. Here are the 5 best options on Amazon UK.

Check Price on Amazon UK →Manrose MF100T Inline Mixed Flow Fan with Timer
A completely different approach — this fan mounts in the loft or inside the duct, not on the bathroom wall or ceiling. That means nothing visible in your bathroom except a small grille.

Reviewers love it: 'Really impressed with how quiet this is and with the suction which you can feel.'
Pros
- Hidden installation (mounts in loft/duct)

- UK brand (Manrose)
- Mixed-flow design for long duct runs
- Built-in timer
Cons
- Larger unit needs loft space
- More complex installation

- Not suitable for direct wall mounting
Who it's for: Bathrooms without an external wall, long duct runs, or anyone who wants the fan completely hidden

Axial vs inline: which type do I need?
Axial fans mount directly on the wall or ceiling and vent through a short duct to outside. They're simple and cheap. Inline fans mount in the loft or inside the duct itself and are completely hidden — more powerful but more complex to install. If your bathroom has an external wall, an axial fan is fine. If not (an internal bathroom with a long duct run), you need an inline fan like the Manrose.
Do I need a timer, humidity sensor, or both?
A timer keeps the fan running for a few minutes after you leave the room — essential for clearing residual steam. A humidity sensor turns the fan on automatically when moisture in the air rises. A timer is the minimum you should accept; a humidity sensor is the gold standard. Basic models with neither require you to manually flip a switch and remember to leave it running long enough.
Can I install a bathroom extractor fan myself?
If you're replacing an existing fan with one that uses the same 100mm duct, most confident DIYers can do it in under an hour. New installations require wiring and possibly cutting new ducting — consider an electrician unless you're comfortable with basic electrics and Part P regulations. All fans on this list fit standard UK 100mm ducting.
We recommend
How powerful does my fan need to be?
UK Building Regulations recommend a minimum of 15 litres per second (54m³/h) for bathrooms. All fans on this list exceed that comfortably. For larger bathrooms, family bathrooms with multiple showers per day, or long duct runs, choose the Manrose inline fan which delivers 95+ litres per second.
