Best Bathroom Extractor Fans for UK Flats
A good bathroom extractor fan is one of the best defences against condensation and mould in a flat — it pulls moist air out during and after a shower, before it settles on cold walls and windows. Modern fans are far quieter than old rattly units, with timers and humidity sensors that do the work for you. This guide rounds up strong options, with the important note that fitting one is a job for an electrician.
QUICK ANSWER
For most flat bathrooms, a quiet 100mm (4-inch) extractor fan with a timer or humidity sensor clears steam effectively without the old-fashioned racket. Fitting or replacing a fan is electrical work — use a qualified electrician, and if you rent, ask your landlord. Renters who can’t change the fan should lean on a dehumidifier and window vacuum instead.
Who this guide is for
Flat owners (and renters with landlord permission) who want to replace a noisy or weak extractor fan to cut bathroom condensation and mould at the source.

How to choose
- Size and airflow: A 100mm (4-inch) fan suits most flat bathrooms; larger rooms or wet rooms may need more airflow — check the extraction rate.
- Timer or humidity sensor: A timer keeps the fan running after you leave; a humidity sensor switches it on automatically when it’s steamy.
- Noise: Modern “silent” fans are far quieter than older units — worth it if the bathroom is near bedrooms.
- Fitting is electrical work: Installing or replacing an extractor fan should be done by a qualified electrician and must meet wiring and bathroom-zone regulations.
- Renters: You usually can’t change a fixed fan yourself — ask your landlord to repair or upgrade a poor one, and meanwhile use a dehumidifier and window vacuum.
Frequently asked questions
Will a better extractor fan stop bathroom mould?
It helps a lot by removing the moist air that causes condensation and mould, especially with a timer or humidity sensor so it runs long enough after a shower. Combine it with wiping down surfaces, a dehumidifier and treating any existing mould for the best results.
Can I fit a bathroom extractor fan myself?
Installing or replacing a bathroom extractor fan is electrical work in a wet area, so it should be carried out by a qualified electrician to meet wiring and bathroom-zone regulations. It’s not a DIY job, and in a rented flat it’s the landlord’s responsibility.
What can renters do if the extractor fan is poor?
Ask your landlord in writing to repair or upgrade a weak or broken fan — adequate ventilation is their responsibility. In the meantime, run a dehumidifier, clear condensation with a window vacuum, open a window after showering, and keep the bathroom door closed while it clears.
Our recommendation
The Manrose QF100T is our top all-round pick for quiet, effective extraction; the Envirovent Silent-100 is the one to choose if noise really matters. Xpelair and Bosch offer dependable and premium options, with the AirTech-UK fan on a budget — and remember fitting is a job for an electrician.
