Our core business is electrical contracting. We have extensive experience in the commercial and industrial sectors and have worked on major industrial, commercial and residential developments. Our commitment to each project ensures we end up with satisfied clients.

Efficient Energy Management

We commit to a project 100%. When we say we will achieve a deadline, we will achieve that deadline. There is a reason that major names in construction work with us again and again. We have an excellent safety record – our mantra is ‘Safe, good-quality work’.

Maintenance / Services

When you have invested in premium quality electricals it makes sense that the people who installed the job (and in some cases designed it) look after it. That’s why we developed our 24-hour-seven-days-a-week maintenance service. And that’s a genuine 24/7 service – we have a dedicated maintenance fleet on the road ready to respond to your emergency regardless of when it happens. We also perform Portable Appliance Testing (PAT) & Emergency Lighting Testing and Electrical Periodic Inspection Testing.
