Built on relationships. Growing through expertise.

Spectrum Group is a family of specialist divisions committed to delivering high-quality, sustainable solutions across the built environment. What sets us apart isn’t just what we do – it’s how we work. For more than two decades, our growth has been shaped by collaboration, trust, and long-lasting partnerships with the clients and communities we serve.

OUR STORY

Spectrum began its journey in May 2000, originally founded as Spectrum Electrical.

We started as a dedicated electrical contractor with a clear focus on quality workmanship, reliability, and strong client relationships. And that focus remains unchanged.

As demand for integrated services grew, our business expanded during the 2010s to include a full mechanical offering, evolving into a complete Mechanical & Electrical provider. This expansion reflected our belief in providing clients with a seamless service built on technical capability and coordinated delivery.

With the changing energy landscape and the increasing importance of low-carbon solutions, we broadened our expertise once again, establishing Spectrum Solar. This specialist division was created with a focus on solar PV, battery storage, and sustainable energy technologies.

Recognising the opportunity to deliver an end-to-end construction journey, we launched Spectrum Construction. This strategic step allowed us to bring all our skills under one roof, offering clients a fully integrated design, build, power, and energy solution.
Our evolution has always been shaped by the same principles:

  • Quality
  • Integrity
  • Collaboration
  • Long-term value
THE HERE AND NOW

Today, Spectrum Group brings together three specialist divisions:

Each division operates with its own dedicated team and specialist focus – yet all share the same values, the same commitment to excellence, and the same belief in doing things the right way. Working together, they allow us to offer a truly integrated approach that benefits clients through better coordination, greater cost certainty, and smoother project delivery.

What our clients have to say

I have worked with Spectrum for nearly nine years, across multiple roles within McCarthy Stone, and they continue to be one of the most reliable and professional contractors I have ever partnered with.

During my time as a Site Manager, Spectrum consistently delivered high-quality plumbing installations on new retirement apartment developments. Their team showed excellent technical knowledge, strong communication skills, and a proactive approach that made them a trusted part of our build process.

In my current position as a Project Manager within the Recovery & Repairs department, I have continued to rely on Spectrum for remedial works and assistance on latent defect projects. Their responsiveness, integrity, and commitment to resolving issues efficiently have been invaluable. They approach every challenge with a solution-focused mindset and maintain the same high standards regardless of the size or complexity of the job.

Spectrum has proven themselves to be dependable, professional, and consistently excellent in the services they provide. I highly recommend them.

I’ve worked with Spectrum at various points over the last decade, and they have consistently stood out as a dependable and professional contractor.

In my earlier role as a Project Manager, I regularly oversaw their plumbing installations on new retirement developments and was always impressed by the standard of their workmanship. Their team combined strong technical ability with clear communication and a proactive, collaborative attitude that made project delivery noticeably smoother.

Spectrum’s plumbing and electrical teams are actively involved in the development I’m currently overseeing. I continue to trust them with both day-to-day works and more complex remedial or latent defect tasks. They are quick to respond, solution-driven, and consistently demonstrate honesty and accountability – qualities that make a real difference on a busy site.

Across every project, Spectrum has been reliable, professional, and genuinely committed to doing things properly.
