What Our Clients Say


We have worked with Orion Mechanical for many years on small and large-scale projects. We are very happy with the service they provide and would have no hesitation in recommending them to any company.

Jamie Crookes - Managing Director, Richards Crookes Construction

I worked with OMS, in a design and construct capacity, on several projects. OMS carried out the mechanical design in a professional manner and in accordance with the design brief. During the construction and commissioning phases OMS completed their works on time and met the operation and quality expectations. I have no hesitation in recommending OMS for the mechanical works for future projects.

Richard Edmonds - Project Manager, Deicorp (previously Parkview)

Orion Mechanical have completed the mechanical works on time and on budget, with a strong commitment to working closely with all stakeholders throughout the projects. This coupled with Orion’s attention to detail makes Orion the right choice for future mechanical works.
