Electricians Services/Electrical Contractors

Switching you on to the best electrical services and contractors.


Crystal Sigma’s electricians are able to professionally carry out any domestic or commercial electrical work, be it the complete rewiring of your home or office, or the installation or relocation of a plug socket.

Since 2005 any work requiring the disconnection of any part of your electrical system must be undertaken by a qualified electrician. This was brought into law for safety reasons, but when the lights go out or some wires need moving we realize you can't wait a week for professional attention.

That's why Crystal Sigma has installed a hi-tech tracking system in all our vans – we can get an electrician to you quickly.

Before any work is carried out, our engineers can provide you with an estimate of the proposed job.

All our electrical work is backed by the Crystal Sigma guarantee of quality workmanship and, unlike other companies, our electricians will always clean up after themselves.

Our team of electrical engineers is qualified to carry out all types of domestic and commercial electrical work, including:

  • Lighting installations
  • New wall sockets
  • Switches
  • Consumer units
  • Appliance connections
  • Extractor fans & hoods
  • Complete rewiring
  • Outside lights
  • Security lighting
  • Fault finding
