Our portfolio of projects is second to none


Every electrical job is different, and each has its unique challenges. The collective experience of our electricians is so broad that they're equipped to handle any challenge that could possibly pop up on the job site.

From the replacing a distribution board to the construction of a new clean room, we bring the best practices and industry knowledge with us to every job. We've worked with blue-chip companies in the following industries:

  • Pharmaceutical 
  • Food & Beverage
  • Healthcare
  • Education.


We have a reputation for completing first rate, quality, on-time & on-budget projects.
We have a portfolio of satisfied customers whose trust we've earned with quality work and the highest levels of professionalism.


Whatever your project, we've got the experience

Expert Work

All of our trade staff are time-served & hand-picked. We DO NOT use agency staff. All of our staff hold JIB Approved Electrician status as a minimum.

Accurate Estimates

We have a policy of open-book pricing and are happy to demonstrate how your money is being spent. We won't always be the cheapest but we endeavour to be the best.

We are committed to providing a quality, best-in-class service to our clients.

Industry-best Quality

We never cut corners on a job, and we never will.

Safety First

Every day at SIGMA begins with a safety tool-box-talk. Staff are required to actively engage in this philosophy & are empowered to stop the job in the event that they witness unsafe behaviour. All of our construction sites are audited for safety compliance by senior management on a weekly basis.
