Really impressive service from the first phone call to the last set of paperwork. Efficient, quick and a great job. Felt totally comfortable with every aspect. I appreciated their advice and they welcomed my shopping around to compare price and service standards. Gave me confidence in their quality and they didn’t disappoint. On-site the guys were great, explained what they were doing and why and got on with the job. Same day service, great pricing and a terrific result. Totally recommend them.

These guys are really good and very professional. The customer service from Natika was a breeze, the quote was very fair and detailed and they did what they said they would with no surprise cost. Ryan the plumber was really great, prompt, polite, friendly, well presented and on time. He did an awesome job too. The Electricians that came to install my powerpoint were very nice too.I definitely recommend GM Hotwater and would use them again in the future should the need arise.

Professional team of workers, from inquiry to installation we appreciated the information given, advice on product suitability and the ability to install at a date that suited us.

Our experience with GM Hotwater was excellent. My wife sent an email through the website and I got a phone call within around an hour. The young lady on the phone, Natika, was a gem. She has a bright and bubbly personality as well as being very knowledgeable in regards to hot water systems. She answered all of my questions and also informed me of a few things that I did not know. She arranged to get a plumber out promptly and my hot water service was repaired. The young lad that did the repairs was polite, efficient and did the job quickly. Again when I spoke to Natika the following day to pay my account there was more of that vibrant personality again. A pleasure to deal with and I would be more than happy to recommend them....Jeff

Initially spoke with Andrew after existing HWS died. He was very helpful in assisting us to make a decision on a replacement and made arrangements promptly. Then had excellent follow up from Nitika with a quote and answers to a few more questions. Sam arrived earlier than scheduled to do the installation and was professional and friendly.Overall turnaround to get hot water running again was really quick which was greatly appreciated on a cold winters day

We had just moved in to our newly bought house and found that the hot water service was leaking. Made a call to GM Hotwater and the gorgeous lady helped me with my queries and booked us in for a quote/repair/replacement. Ryan arrived on time, was super friendly and he was so helpful. We ended up replacing the unit after our discussions with him. He had great knowledge on the Rinnai products and what we needed. He tided up a few bits and pieces from the previous installer (without asking as he was concerned about some of the fittings) and I would recommend him a thousand times. Great Job Ryan!

We have just enjoyed a hassle free process of changing over from a heat pump that has served us well for almost twelve years to a new one supplied and installed by GM Hot Water Beginning with a prompt quote and other useful information from Natika in the office to the installation by thePlumbers and Electricians we can say without hesitation that thus far it has been a job well done. So keep up that good work.

We have just had a new Rinnai solar hot water system installed by GM Hotwater. Our experience has been excellent right from working out what system we needed to the installation and paying for it. The trades being Plumbers and Electricians were very efficient and tidy throughout the install. Great to converse with and worked right through lunch in order to get the job done. I can definitely recommend this company if your considering a hot water system. Lyndon

Very prompt service and straight to the point supplying a great offer not worthy of shopping around for a better deal! Natika updated myself on weekends and before business hours proving to go above for the customer. The two lads who fitted our HWS were great service men and although having a big job late in the day to complete, they happily removed all our old solar and tanks to make the end product just that little better removing an eye sore we had on the front of our roof!
23:31 22 May 20
Brilliant work. Service was super fast- barely a few hours after calling and my new system was up and running. Staff were also fantastic- very friendly and went out of their way to explain what they were doing and why. Can't rate them highly enough. Will absolutely call again if I even run into any issues 🍻
08:11 21 May 20
It's a pleasure dealing with GM Hot water from A to Z. The quotes were done efficiently and professionally. Within minutes the options were emailed and clearly explained. The service was second to none. A plumber was at my doorstep early next morning and the job was done timely. His pleasant personality and workmanship were admirable.
09:56 20 May 20
These guys did my meter to house install, aswell as gas oven and hot water system. With 15-20meter pipe install. Great professional team. Very accommodating and good at their job, would recommend.
This is what all Service should be measured by/against, from initial call to install took about 36 hours, unit arrived 8:45 the next morning and the installers were here at 8:50, job done everything cleaned and old unit taken away, Well done guys. Fantastic.
