About Simmark

Mark and Dee-Anne Simms started Simmark as a small electrician’s company in North Nowra over twenty years ago. Over time, they grew the company and gradually added more capabilities such that Simmark today occupies a unique position as a versatile and highly flexible multi-service contracting company.

In early 2016, Simmark’s General Manager, Matthew Simms, became a director of the company as part of a generational transition at Simmark. Simmark also brought in a new investor and the company embarked upon an expansion plan.

As of June 2020, Simmark has grown to more than 65 employees and operates in a service area broadly covering the Shoalhaven, Illawarra, Southern Highlands and Eurobodalla regions of New South Wales.

A big team came and installed the lot in one day. A very professional approach. Installed compressor units under house as requested. Called back to better secure underhouse wiring.

Solar Panel - Winaico


They work well and consistently.

Solar Inverter - Enphase


One micro invertor failure in first 6 months replaced under warranty at no cost. Actually diagnosed from the handy phone app. & replacement completed whilst we were 5,000km away from the house!

The onsite visit was a reassuring factor, along with all paperwork, testing, dealing with power company and organising smart meter etc, and local office to deal with any queries. Will look at batteries next year, maybe. Thanks for your help
