Our Story

Specialist expertise. Genuine independence.

JDE Engineering Services Ltd is a specialist consultancy focused on data centre commissioning and Safe Systems of Work. We work with operators, contractors and hyperscale developers across the UK and Europe to ensure critical infrastructure is delivered safely, compliantly – and proven to perform before it goes live.

Our team brings deep technical expertise in electrical systems, mechanical systems and integrated testing, combined with a practical understanding of the pressures, risks and complexity of live data centre environments.

“Commissioning is the point where systems are tested under real conditions, verified against design intent, and certified ready for operation. That is what we exist to deliver.”
Josh Holland – CEO

How we Work

Our Approach

We engage from the earliest stages, reviewing designs, identifying commissioning risk, and building a strategy that protects delivery.
02

Testing & Verification

Rigorous pre-functional and functional testing, overseen by experienced engineers who know what good looks like.
03

Certification

Evidence-based reporting and formal certification that gives clients and operators confidence at handover.

What we Stand For

Our Values

The principles that guide every project we take on.

Safety First

No project outcome is worth compromising the safety of people or assets. We build safe systems of work into everything we do.

Independence

We provide genuinely independent assurance. Our job is to verify performance,not to sign off what we’re told.

Technical Rigour

We apply engineering discipline to every engagement. Evidence-based. Methodical. Thorough.

Reliability

We show up, we deliver, and we are accountable for the quality of our work – every time.

Collaboration

We work as part of the wider project team, communicating clearly and supporting everyone involved to achieve a successful outcome.

Integrity

We operate with transparency and honesty with clients, partners, and the people on our projects.
