Our Services
One Team.
Every Trade.
Zero Compromise.
From high-end Cat B fit out to complex multi-trade delivery and ongoing hard services FM — Leonis Group provides a fully integrated, single-point solution for the UK's most demanding commercial environments.
What We Deliver
End-to-End Capability Under One Contract
Most contractors specialise in one discipline and subcontract the rest. Leonis Group is different. Our in-house teams span fit out, mechanical, electrical, joinery, drylining, and hard services FM — giving clients a single point of accountability from initial brief through to long-term maintenance.
01 — Gas. Electrical. Mechanical. Compliant.
Hard Services FM
Leonis Group delivers a fully managed, compliance-led hard services FM solution across gas, electrical, mechanical, and HVAC disciplines — serving both commercial and domestic clients. From planned preventative maintenance programmes through to rapid reactive call-outs, our in-house engineers keep critical building systems operational — with full certification and job records returned after every visit.
Sectors
02 — Cat A & Cat B. Shell to handover.
High-End Fit Out
We deliver high-specification fit out projects for the most demanding commercial clients — from Cat A shell and core preparation through to fully bespoke Cat B interiors. Every project is managed by an experienced team with the technical depth to handle complex specifications, tight programmes, and live building environments.
Sectors
03 — Clean. Maintained. Presentable.
Soft Services FM
A well-maintained environment reflects the standards of the organisation within it. Leonis Group delivers a comprehensive soft services FM offering — from daily cleaning and building washes through to grounds maintenance and waste management — ensuring your premises remain presentable, compliant, and fit for purpose at all times.
Sectors
04 — All trades. One contract. No interfaces.
Multi-Trade Solutions
Our multi-trade capability removes the complexity of managing multiple specialist contractors. Mechanical, electrical, plumbing, joinery, drylining, and more — all coordinated and delivered by Leonis Group under a single contract, with a single programme and a single point of responsibility.

How We Work
A Process Built Around Your Project
01
Brief & Discovery
We start by understanding your project in full — scope, programme, budget, and any constraints. Senior leadership is involved from day one.
02
Programme & Pricing
We develop a detailed programme and transparent cost plan. No hidden costs, no vague allowances — a clear picture of what we'll deliver and when.
03
Mobilisation
Our in-house teams are mobilised quickly. Trade coordination, logistics, and site setup are managed by our own project managers — not third parties.
04
Delivery
We execute to programme, managing quality, safety, and client communication throughout. Regular reporting keeps you informed at every stage.
05
Handover & Beyond
We don't disappear at handover. Snagging, commissioning, O&M documentation, and ongoing FM support are all part of the Leonis Group service.
