Bathroom extractor fan installation in Southall
Remove moisture and meet Building Regs in Southall
A bathroom extractor fan removes moisture from the air before it condenses on walls and ceilings. In Southall properties — many of which are Victorian and Edwardian conversions with solid walls and limited natural ventilation — condensation and mould are common without adequate extraction. A correctly ducted fan drawing at least 15 litres per second resolves most condensation problems.
Building Regulations Part F requires mechanical ventilation in bathrooms without an openable window. Part P requires that any new wiring in a bathroom — including a fan circuit — must be carried out by a Part P registered electrician and registered with Building Control. Our electricians serving Southall self-certify all installations and notify Ealing Building Control automatically, providing a completion certificate.
Fan types available for Southall properties include axial ceiling fans with direct ceiling void ducting (the most common and most economical), inline centrifugal fans for quieter operation and longer duct runs, humidity-sensing fans for automatic control, and overrun timer fans for post-use extraction. All installations use rigid duct where possible and include a non-return flap at the external outlet.

What we install
Extractor fan services
Ceiling extractor fan
Core drill through ceiling into ceiling void with duct run to external vent tile or wall outlet. Wired to switched live, overrun timer, or humidity sensor. Most common installation for London bathrooms.
Wall extractor fan
Core drill directly through an external wall — the simplest ducting route. Suited to ground-floor bathrooms and rooms with accessible external walls. Non-return flap fitted at the external vent.
Inline centrifugal fan
Fan motor sits in the loft or ceiling void rather than in the bathroom — significantly quieter. Ideal for large bathrooms, en suites, and properties where noise is a concern. Rigid duct run included.
Humidity sensor fan
Automatically activates when humidity rises above the set level — no switch required. Ideal for rental properties and landlords with HMO licences. Overrun continues until humidity drops below threshold.
Fan with overrun timer
Fan continues running for a set period (typically 15 minutes) after the light is switched off. Removes residual moisture after the bathroom is vacated. Adjustable timer included on most models.
Duct cleaning and inspection
Check existing duct run for disconnected sections, blockages, and collapsed flexible duct. Non-return flap inspected for free operation. Duct cleared and resealed where required.
