Lighting Up Nelson for Over 30 Years

Back in 1992, Glenn Roberts started a small family-owned electrical business with a simple goal: to provide reliable service and honest advice to the Nelson community. What began as a one-man operation soon grew, powered by hard work, trust, and a passion for quality. Over the years, that little business evolved into GRE Services—a name that reflects our growth while staying true to our roots. Today, we’re proud to be a locally owned company with a reputation for excellence across the Nelson Tasman region.

From architecturally designed homes to large commercial projects, we’ve tackled it all. Our team brings decades of experience to everything we do—whether it’s a quick repair, a full-scale fit-out, or cutting-edge solutions like solar power and smart automation.

More than 30 years on, our mission hasn’t changed: deliver exceptional electrical services with a personal touch. GRE Services—trusted by generations, ready for the future.

A Bright New Chapter

2024 marked an exciting turning point for GRE Services. We moved into a modern, purpose-built workspace designed to boost efficiency, foster collaboration, and support the growing needs of our customers. This wasn’t just a change of address — it was a step into the future.  Alongside the move, we refreshed our brand to reflect who we are today: a team that values integrity, quality, and progress. GRE Services isn’t just about electrical work—it’s about building trust, solving problems, and creating smarter, more sustainable solutions for our clients.

Another milestone came with Colin White and Rebecca McLean joining Josh Roberts and Nic Strom as co-owners and directors. Their combined experience, leadership and shared commitment to our values strengthen our foundation and ensure we stay true to what matters most: our people, our customers, and our community. Today, GRE Services stands ready for the future—powered by a passionate team, a strong legacy, and an unwavering commitment to excellence.

What Our Customers Have To Say About Us

We have just completed the 1st phase of our kitchen remodel and are so pleased with the work from GRE Services. Allan is certainly the right person for our project as he brings a wealth of knowledge and both Allan and Riley have been a delight to work with. We look forward to our next phase, plus we hope that we are able to continue to have Allan as our sparkie on future electrical work.

Thank you for taking such good care of us. We know we are one of the smallest of your clients, but we feel the attention is the same as one of the largest. We so appreciate working with GRE.

I am delighted with the services of Justin, assisted by Riley, in installing two sets of twin heated towel poles in my residence. While the assignment is not yet completed, the imagination and skill of your sparkie has resulted in a significant visual enhancement of the two ensuites. I don’t think this has been an easy assignment; nonetheless he’s gone about it systematically and diligently, and with good cheer, to achieve exactly the outcome I wanted.

This is the second time I have called on GRE for electrical assistance since I purchased my new Nelson home in October. On both occasions I have been well-served by your competent and pleasant team. Thank you.

My solar panels have been installed and I’m very happy with the service from GRE. The process of getting a quote was clear and easy to follow. All my questions were answered in a way that improved my knowledge of what my system would do.

The installers were respectful and efficient and kept me informed as they went along. I look forward to lower power bills!

Jan Marsh

Michael and I would like to thank your company for the best service I think we have ever had. The young guy arrived exactly on time, as was promised by your company. He did the job quickly, did not leave a mess, followed instructions and completed the job in a very good time. I want to thank your company and the young guy.

I would not hesitate to recommend people to use your company. Once again, thank you.

Diana and Michael Connolly

We have been involved in a number of projects with Glenn Roberts Electrical, the first of which was the Saxton Oval Pavilion.  Since then, we have worked together on a variety of commercial and high-end residential and rest-home projects.  All of the team at Glenn Roberts Electrical have been professional and approachable and we have worked together to deliver some fantastic results. Their ability to perform to a high standard on site, but also provide design solutions and manage costs ensures that they are an electrical firm of choice for us as a main contractor. The site foreman that we have worked with have been the highest quality and their input during projects has been invaluable in their success. Glenn Roberts Electrical has a very good communication channels that allows decisions to be made quickly. I have no hesitation in recommending Glenn Roberts Electrical for projects on any scale and would definitely continue to use them for upcoming projects.

The Suter Art Gallery uses a variety of lighting throughout its building, from specialist exhibition track lighting; lighting for ambiance including uplighting and spotlighting architectural features; lighting for way-finding, working and safety; outdoor lighting.   The KNX system allows the lighting to be selectively turned on and off using a tablet with just a finger swipe and touch onto simple graphics.

I was told we would have had row upon row of switches had we not got KNX control, instead we have 3 very discrete devices controlling several hundred lights and the sun blinds in the entrance lobby – which makes things very easy to use.

GRE were the electrical contractor on our house build in Mapua. Their input was one of the highlights of the build process. They provided great input on the design of all of the electrical systems covering lighting, PV, automation and general power and showed patience while we figured out our final requirements with other contractors. On the job they were courteous, on time, kept us informed, and did what they said they would do.

We love the outcome and would recommend the GRE team to others.

With 6 Radio Brands coming out of the one building – and with MORE FM as the Civil Defence Radio Station for the region – when the lights go out in the city, the power needs to stay on at Fifeshire House.  So, when we identified stability issues with our emergency electricity backup system, we put the call in to Glenn Roberts Electrical.  They’ve responded brilliantly, at times in the ugly hours of the night, to some challenging situations. All throughout they have consulted and worked with our Engineering Department to ensure we get the power we need to stay on-the-air.

Glenn Roberts Electrical deserve their reputation and their 30th anniversary celebration!
