M&E in Action: What Real Turnkey Delivery Looks Like

The phrase “turnkey M&E” gets thrown around a lot. But for those delivering the work; on live sites, with tight timelines, across multiple trades, the reality looks very different. At Heb Mechanical & Electrical, turnkey isn’t a tagline. It’s a commitment to getting every stage right: from design and install, through to testing, handover, and long-term performance.

This isn’t about selling services. It’s about raising standards and sharing what works. Because in our experience, successful projects come down to process, clarity, and consistency. Clients don’t just want systems that meet spec, they want systems that work, teams that communicate, and a handover that stands up to scrutiny.

So what does that look like in action? Below, we’ve broken down how we approach each stage of the job and how that ties into the bigger picture of operational performance, risk, and long-term value.

Good design makes everything else easier. The best M&E projects start with conversations, not drawings. We work closely with clients, consultants, and contractors to make sure every system is designed not just for compliance, but for construction. That means checking access, coordination, sequencing, and future maintenance before anything hits site.

Beyond layouts, our design input helps shape energy performance, lifecycle efficiency, and cost certainty. Whether we’re leading the full design process or reviewing another team’s concept, we focus on buildability and long-term value. Read more about our M&E design process.

Installation is where things get real. If design is the plan, install is the execution and the difference between the two is often people, process, and pace. Our installation teams cover the full spectrum of mechanical and electrical systems: HVAC, lighting, power distribution, fire alarms, BMS, and containment.

We also adapt to how projects are really delivered. Sometimes that means working in phased environments, sometimes around live operations, sometimes with partial access. Our job is to make it work and leave every stage ready for the next. Explore our installation capabilities.

Testing and commissioning is where you find out whether everything that came before has actually worked. For us, this stage isn’t just about functional tests, it’s about confidence. It’s where the client gets clarity, the systems get validated, and the handover becomes real.

Just as important as the tests themselves is the information handed over with them. We provide full O&M manuals, asset registers, certificates, and guidance for FM teams and end users. Our goal is to leave clients with systems they understand, not a folder of documents they can’t use. Learn more about how we manage testing and commissioning.

Once a project’s handed over, the real work begins. That’s where our other divisions, Facilities Management and Cleaning & Hygiene + Security, come into their own. We don’t walk away at project completion, we stay close to ensure systems stay compliant, spaces stay safe, and operations stay smooth.

From routine PPM and reactive callouts, to life-cycle reporting and system optimisation, our FM team ensures buildings perform well beyond install. We use smart alerts, asset tracking, and mobile support to fix problems before they escalate, all built on what’s been installed. Also, we don’t forget the human element. Our Cleaning & Hygiene + Security division helps maintain safe, compliant spaces that meet the expectations of staff, patients, tenants, and visitors, particularly in high-footfall or critical environments.

That joined-up approach across M&E, FM, and Cleaning & Hygiene is what creates true operational resilience. It’s what makes buildings work, long after we’ve left site.
