Hole Coring for Electrical Installations
Clean wall openings for suitable electrical and ventilation work
Some electrical and ventilation installations need a neat opening through masonry or other suitable construction.
Coring is a supporting service and should be planned around the route, hidden services, structure and finish.

What Hole Coring for Electrical Installations Includes
Core drilling for electrical and ventilation installations.
The exact scope depends on the existing installation, the property or site conditions and the customer-safe information confirmed before work begins.
- Extractor fan openings
- Suitable cable routes
- External outlet coordination
- Route assessment
- Dust and finish planning
- Electrical installation coordination
Before coring, the route should be checked for hidden services, structural concerns and finish issues.
Why the service may be needed
Neater penetrations
A cored opening can be cleaner than rough breakout where the wall is suitable.
Extractor routes
Fans often need an external route through a wall.
External supplies
Some outdoor circuits need a controlled route from inside to outside.
Common applications
Coring is used only where the route and building fabric are suitable.
- Bathroom extractor fans
- Kitchen extraction
- Outdoor electrical routes
- Garage supplies
- Garden supplies
Before coring, the route should be checked for hidden services, structural concerns and finish issues.
Coring considerations
Diameter and route
The opening size and angle must suit the duct or cable arrangement.
Internal and external finish
Access, dust, brickwork, render and sealing should be considered.
Electrical coordination
Coring is planned with the electrical route rather than guessed separately.
