Our Trusted Partners

A culture of striving for excellence combined with motivated and dedicated staff is what defines CWL Group. Their workmanship is second to none and it is obvious that all of the staff care about what they do. Commitments are met and exceeded and there are no problems that can’t be resolved. I’m looking forward to working with Clayton and his team in the future and have no hesitation in recommending them to anyone.

The team from CWL Group are very reliable, responsive and efficient in their work. They go above and beyond to make sure the job is completed at its highest standard. The knowledge of the guys is exceptional. I would recommend the CWL Group team every time!
- Annemarie Rodrigo, Bellevue Hill House Keeper
I want to thank CWL Group for the outstanding work in installing our hydronic heating system. I have worked with many plumbers over the years and I have never seen such a high standard of workmanship. They came in on time and on budget. I cannot recommend the team from CWL Group highly enough.
