Irish contractor Designer Group is working on 10 separate schemes across Heathrow Airport, covering essential infrastructure and passenger-facing improvements at one of the world's busiest aviation hubs. The programme spans everything from a new Virtual Control Facility to airline lounge fit-outs, at an airport handling more than 80 million passengers a year.

Designer Group, headquartered in Blanchardstown, Dublin, is a mechanical and electrical engineering contractor founded by chief executive Michael Stone in 1992. The company reported turnover of €275 million in 2025 and operates across Ireland, the UK, Europe, Africa and the United States.

Since first commencing work at Heathrow in 2017, Designer Group has strengthened its expertise in delivering engineering solutions within live operational settings, coordinating with multiple stakeholders to minimise disruption to airport activities.

A flagship element of the programme is the Virtual Control Facility, which provides a state-of-the-art backup to the airport's control tower.

Additional projects include upgrades to staff security screening in Terminal 5, the full MEP fit-out of two new staff and vehicle control posts, office refurbishments, installation of pre-conditioned air units at aircraft stands, airline lounge fit-outs and ongoing MEP condition and validation surveys.

The structural driver is Designer Group's specialisation in live-environment MEP delivery, allowing it to secure repeat multi-scheme work across a single operationally critical site rather than competing project by project for standalone contracts.

"We don't chase turnover for its own sake, we pursue opportunities where we know we can add genuine value, and that's in sectors like data, energy, and life sciences," said Paul Nicholls, group managing director at Designer Group.

Delivering within a live airport environment requires meticulous planning, stringent safety measures and careful coordination with numerous parties, in a highly regulated, security-sensitive setting where maintaining operational continuity is critical.

For the sector, the Heathrow programme illustrates how established M&E contractors are building long-term, multi-scheme relationships within operationally critical infrastructure rather than pursuing one-off fit-out contracts.
