Extractor Fans and Ventilation
Domestic extractor fan installation and replacement
Extractor fans help remove moisture, odours and stale air from rooms that generate steam or condensation.
A suitable fan depends on the room, duct route, controls, electrical supply and building fabric around the outlet.

What Extractor Fans and Ventilation Includes
Extractor fan installation and replacement for homes.
The exact scope depends on the existing installation, the property or site conditions and the customer-safe information confirmed before work begins.
- Bathroom fans
- Kitchen extraction wiring
- Utility-room fans
- Fan replacement
- Timer and humidity controls
- Fan isolators
Fans and controls must be suitable for the room and installed with appropriate isolation and protection.
Why the service may be needed
Condensation and steam
Poor ventilation can contribute to damp surfaces and uncomfortable rooms.
Failed or noisy fans
Old fans may stop working, become noisy or no longer suit the room.
Renovation timing
Bathroom and kitchen works are a practical time to route wiring neatly.
Common ventilation applications
Extractor work is usually driven by moisture, odour, renovation or replacement needs.
- Bathrooms without fans
- En-suites
- Utility rooms
- Kitchen alterations
- Humidity controls
- Duct route changes
Fans and controls must be suitable for the room and installed with appropriate isolation and protection.
Fan and control options
Timer fans
A run-on timer can keep extraction running briefly after the room light is switched off.
Humidity controls
Humidity-controlled fans may suit rooms with recurring moisture.
Separate switching
A separate control can be useful where fan operation should not always follow lighting.
How We Complete Extractor Fans and Ventilation
Each extractor fans and ventilation project has a service-specific scope, with more detail available in our shared electrical project process.
Step 1
Initial discussion
We confirm the domestic requirement, who the work affects and the practical reason for the enquiry.
Step 2
Site assessment
The existing installation, access, likely cable routes and any constraints are reviewed before the scope is finalised.
Step 3
Scope and quotation
The quotation describes the agreed extractor fans and ventilation scope, known assumptions and exclusions.
Step 4
Planning and access
Dates, isolations, access arrangements and coordination with other trades or site users are agreed before work starts.
Step 5
Installation
The work is completed with attention to room use, fan selection, route constraints, control wiring, isolation and finished testing.
Step 6
Inspection and testing
New or altered electrical work is inspected and tested where required before handover.
Step 7
Certification and handover
Appropriate certification, labels, records and operating information are provided for the work within scope.
Regulations, Safety and Scope
Designed, installed, inspected and tested to the current edition of BS 7671 and applicable Scottish Building Standards requirements.
Earthing, bonding, circuit protection, cable routes and certification are reviewed where they affect the agreed work.

Extractor Fans and Ventilation Questions and Answers
Do you core the hole for a fan?
Where suitable and agreed, hole coring can be coordinated as part of the installation.
Can a fan run after the light is off?
Yes, timer controls can provide run-on operation where wired correctly.
Can a fan be replaced without changing wiring?
Sometimes. The existing wiring, isolation and fan type need to be checked first.
