Trusted by the nation’s largest and most prestigious organisations to deliver in their business critical environments.


Working with blue-chip organisations in the financial and technology sectors, as well as the healthcare and custodial sectors, Arthur McKay has decades of distinctively diverse “critical environments” experience.

This experience and knowledge has led to tried and tested working practices to ensure the success of any work carried out. From data centres to laboratories and courtrooms to operating theatres, Arthur McKay ensures its clients’ operations remain intact.


Arthur McKay’s ethos is to self-deliver mechanical, electrical and data services, in order to ensure clients consistently receive the best possible service. This is achieved by having a large directly employed team who are developed through an in-house training department, guaranteeing Arthur McKay’s colleagues are some of the best trained individuals in the industry.

For example, when working in data centres only experienced colleagues will be assigned to these projects, using a tried and tested procedure and system of work. This can include providing a temporary plant and equipment, designed to maintain services or a specific set of environmental conditions; therefore ensuring your business continuity and protecting your assets.


When working in critical environments, the importance of planning the commissioning stage cannot be under estimated.

The experts at Arthur McKay are experienced in delivering the most complex of critical infrastructure projects.  By simulating critical equipment failure or power outages, as part of Arthur McKay’s Integrated Systems Testing (IST),  clients have added peace of mind that their standby systems function as intended.

Arthur McKay’s vast operational experience in Risk Assessment, Risk Management and Contingency Planning, within this type of environment, is a key success factor for our clients.


For many clients, their business continuity is crucial and, so, maintaining their services infrastructure is critical.

For example, if a data system becomes unavailable due to direct loss of power or becomes unstable through a mechanical failure, then company operations may be impaired or stopped completely. This could mean losing serious sums of money or, for healthcare clients, it could even mean putting people’s lives at risk. So, when it comes to delivering critical infrastructure projects, you can rely on the Arthur McKay team.

A Proven Track Record

Working at the leading edge, Arthur McKay’s experience includes designing and delivering large, high availability, business critical data centres from N rating to 2(N+1), which is a key differentiator from the usual mechanical and electrical contractors.

Whether your requirements include building or upgrading a data centre, server room / computer equipment room, or even working in a hospital or pharmaceutical clean room environment, you can rely on the proven track record of the Arthur McKay team to successfully deliver your critical infrastructure project.
