Condensation and mould are among the most common problems in UK homes, particularly in bathrooms and kitchens without effective ventilation. A correctly sized extractor fan, sensibly positioned and wired with an overrun timer or humidistat, makes a real difference.
We install new fans and replace noisy or failed ones, including quiet, low-energy models and fans with humidity sensing. We'll ensure the fan is suitable for the bathroom zone and wired with the correct isolation.

Good to know
Ducting and core drilling
Wall-mounted fans normally require a hole through an external wall. We'll confirm on survey whether core drilling, ducting or a ceiling/loft route is needed.
How much does extractor fan installation cost?
Every job is different, so we price it once we understand what's needed. The main factors are:
- Wall, ceiling or inline fan
- Core drilling or ducting required
- Timer, humidistat or PIR control
- Access to the loft or external wall
We explain charges before we attend and agree the price of any work with you before it starts. Sending photos in advance helps us quote more accurately.
Extractor Fan Installation: FAQs
Should my bathroom fan have a timer?
An overrun timer or humidistat keeps the fan running after you leave the room, clearing moisture that would otherwise condense. It's usually a worthwhile addition.
Can you replace a fan using the existing hole?
Usually, yes, if the new fan is a suitable size. Using the existing aperture keeps the job quick and tidy.
