Quick to reply to my initial enquiry with the exact information I had requested. The quote was straight forward and easy to understand. The job was arranged and tradesmen turned up on the right day right on time. The tradesmen were friendly, polite and professional, got the installation done quickly, didn't leave any mess. made sure it was working before they left. Took away the old storage tank and the packing from the new one. I was very impressed, can't fault the service, highly recommend them.

The Immerge Group’s installation of my Heat Pump hotwater service was excellent. From my first contact with Jayden in Head Office to the installation with the plumbers and electrician. The results were outstanding, well done team!

I had Julian attend my property to replace the front tap and the part as the pressure had dropped. What a sterling job he did. He seemed to know everything fixed the problem very polite and great customer demeanour he had. He fixed the hot water system issue gave tips how to address things. He and his partner were amazing. Thank you Julian and classic example of great customer service that I will remember. 5 stars to you mate. Keep up the great work.
