About Calderstone 
Calderstone started with a simple idea: electrical contracting should be dependable. Our crews turn up when promised, work safely, leave clean sites and hand over systems that have been properly tested.
Cable pulling, glanding and termination, panel installation, containment, testing and commissioning.
Fire alarm and emergency cabling, BMS installation and structured cabling under one accountable team.
