What our clients say…

At Level Construction we believe that whether you are an independent customer or a small to large contractor, Optum offers the same personalised service and attention to detail for every single project. Dealing with a like minded company who are result focused is not only important to us from a continuity perspective but is also a valuable marketing tool to promote to future clients. We can offer our clients quality assurance that we use only the very best subcontractors on all our builds. Regardless of your requirements, Optum can advise on old school plumbing practices or offer innovative ideas and advice, so that we can best support our clients to build their dream home. Optum Plumbing Wanaka are certainly one of the most professional and skilled subcontractors we have ever worked with, not only as individuals but a company who prides itself on working as a team.



Optum carried out the plumbing, gas and drainage services for our latest project in Wanaka. The work was of the highest standard with great communication throughout the project. Their work is the tidiest we have ever seen. We would have no hesitation to recommend Optum to all future clients.



Optum Plumbing & Energy Solutions designed and installed an efficient and modern underfloor heating, solar water heating, a Woodpecker pellet boiler and associated controls to our new house build near Cromwell. The design and consultation process was detailed and easily understood and Kevin from Optum expertly outlined the benefits and downfalls of various systems. The entire system is very easy to operate and provides considerable savings on our home and hot water heating. Any initial issues were quickly and expertly resolved and back-up support is always promptly dealt with if required. We are thoroughly impressed with the system and enjoy a warm and comfortable house without excessive energy bills. We could not imagine a better plumbing company to work with.


I’d just like to say thanks for the prompt service and the two tradesman/persons did a great job and were a pleasure to work with! As I’m not a builder from the area I have given my clients your details for any work they may need done in the future.



Just wanted to convey our thanks to you and your team for your contribution to our project. It has been,overall, as straightforward as it could possibly have been-although the complexities of an off grid system have at times seemed daunting! Kurt and all the others have always been obliging and helpful-including with the ongoing fine tuning of the system.


Our architect had recommended electrical underfloor heating and whilst the initial capital cost was much less, Kevin convinced us to pay a higher initial cost and pay substantially less as running costs through the year. It took a little while to settle down, but to be fair that was due to incompetence from our electrician and when we got an electrician as competent as our plumber all was fixed and we are good now.


Kevin Henderson (Optum Ltd) did all the plumbing work for our house in Bannockburn, built in 2007. Kevin and his staff brought a high level of expertise to what was a complicated job, which included solar and gas installation, under floor heating, storm water reticulation, and plumbing of kitchen, laundry and bathrooms. They were a pleasure to have on the job and Kevin ensured that all work was done in a timely manner. The back up and maintenance provided by Optum since the house build has been excellent. Kevin stands by his work. I would have no hesitation in recommending Kevin and his firm. He offers clients integrity, expertise and a professional approach.



We found Optum Plumbing to be a very professional and easy company to work with, starting from initial consultation and design, right through to installation. The whole job, including ground works for storm water and sewerage, general plumbing and an integrated solar/wet back/radiator central heating system, was completed on time and to quote. Their advice was invaluable, particularly for the central heating system. Their employees worked to high a standard, taking obvious pride in their craftsmanship. Ultimately we have what we want, a simple to heat and warm house, thanks to Optum Plumbing.


We were very pleased with both your promptness & workmanship and will recommended your firm to others.


I did a big build out in Dalefield. I paid top dollar to get the best of everything. However, I used different suppliers and I ended up with a system that wasn’t integrated, was difficult to use, and just didn’t achieve what was promised.

I got Kevin and Optum involved and they took action to integrate everything and actually make it work.

If I’d had them involved from the start I’d have saved tens of thousands of dollars and I’d have gotten what I wanted.

Don’t make the mistake I did!


We had a complex build in Wanaka for our home. 

Optum service was excellent and of the highest quality critical to  the success of the build.

After completion when further extensions were planned also  they were interested efficient and approachable in their service with a total professional standard.

Both Isabelle and I would highly recommend them to any person contemplating  a build, extension  or repair.

We made the right choice using Optum for our plumbing. Our rural block and non-standard heating system were well designed and the team went above and beyond to fine-tune and have it working as we wanted. We learned that plumbing is not an area to cut costs and it really makes a difference having a team who are skilled and familiar with complex systems and new technologies. We would certainly use Optum again.
