How Onyx started

It started with one question

“Why do organisations with good information still struggle to make confident decisions?”

After more than 15 years across education, healthcare, defence, pharmaceutical manufacturing, leisure and commercial property, Shaun kept coming back to that question. The answer wasn't a lack of information. Fire risk assessments, legionella reports, condition surveys and contractor certificates were all there. What was missing was the time to step back and see the bigger picture.

That became the foundation of Onyx: not another compliance company, not another facilities management provider, but a consultancy focused on understanding. Through monthly estate assurance, hands-on project and CDM support and independent consultancy, we help the people responsible for buildings know where they stand and what to do next.

What we believe

How we work with you

01

Independent

We don't sell products or services you don't need. Our advice is objective, honest and focused on your long-term interests.

02

Evidence first

We join up the information you already hold, so decisions are made on evidence rather than assumptions.

03

Practical and plain

Clear priorities, plain English and recommendations you can act on, not reports that sit in a drawer.

04

A partnership that grows

Every visit adds to what we know about your estate, so our advice gets better the longer we work together.
