“I have worked with Mark and the Sigma team for many years. We have been involved in multiple different fast track commercial projects and high end residential works. I have always found Mark and his team to be totally professional; their detailed design is second to none and they have always delivered on each project with complete satisfaction."

S . Good - Sales Engineering Manager
"We have had an ongoing partnership with Sigma that started in 2017.
Throughout this time it’s been very clear that their approach to design has commission-ability as a key consideration - As such they repeatedly produce high quality and commission-able systems that leave both ourselves and the client extremely satisfied."
