About Leonis Group
Built on Trust.
Driven by
Excellence.
Leonis Group is a specialist fit out and hard services FM contractor delivering complex, high-value projects for the UK's most demanding commercial environments.
Our Story
Founded at the Highest Level.
Leonis Group was founded by two industry specialists — one with a career in high-end construction and fit out, the other in hard services FM — both having operated at COO and CEO level for multi-million pound organisations. Having worked at the highest levels across the UAE and the UK, they returned with a shared ambition: to build a contractor that genuinely raises the bar.
Today, Leonis Group operates across the UK delivering high-end fit out, multi-trade solutions, and hard services FM under one roof. The founders' integrated model means fewer interfaces, tighter control, and consistently better outcomes — backed by the kind of senior-level ownership that most contractors simply can't offer.

The Standards We Hold Ourselves To

Accountability
We take full ownership of every project. One point of contact, one contract, one team responsible for the outcome.

Quality
We don't compromise on finish, specification, or workmanship. Every project is delivered to the standard we'd be proud to put our name to.
03
Integrity
We say what we mean and do what we say. Transparent communication and honest relationships are the foundation of everything we do.

Expertise
Our people are specialists. Deep technical knowledge across all trades means we solve problems others can't and deliver results others won't.
