Manchester Airport - Terminal 2 & Pier 2
Delivering large-scale MEP infrastructure to support the transformation of a major international airport
We deliver high-quality mechanical and electrical engineering services across the built environment. With over a century of experience, we combine technical expertise, offsite innovation and collaborative delivery to create resilient, efficient and future-ready buildings and infrastructure.

We are a leading construction and engineering business delivering mechanical and electrical engineering solutions for complex projects across the UK and Europe.
With more than 105 years of experience, we have built a reputation for reliability, technical excellence and consistent delivery. As an independent, family-owned business, we are financially secure and able to take a long-term, responsible approach to our projects and partnerships.
Our Engineering teams bring deep industry knowledge and proven leadership, ensuring projects are delivered with confidence from concept through to completion.

Our Engineering business specialises in the design, offsite manufacture and installation of mechanical and electrical systems. Supported by over 100 technical designers and managers, more than 60 BIM and CAD specialists and dedicated offsite manufacturing facilities, we deliver efficient, coordinated and high-performing solutions.
We operate nationally with a strong local presence, supported by offices, manufacturing facilities and live project sites across the UK.
We deliver high-performance mechanical and electrical engineering services across the UK’s most complex, regulated and operationally critical sectors. Our depth of expertise, scale of delivery and proven project pedigree enable us to support clients from concept through to long-term operation.

We deliver efficient, high-performing facilities that increase productivity and operational resilience. Our teams regularly work in live manufacturing environments, maintaining continuity while delivering complex upgrades and new facilities.

Our experience in commercial and critical business environments spans more than six decades, beginning with the engineering systems that supported the vision for the National Exhibition Centre.

We deliver resilient, energy-efficient mechanical and electrical systems for mission-critical digital infrastructure. Our expertise supports high-availability environments where performance, reliability and scalability are paramount.

We provide end-to-end engineering services to the UK’s defence estate, supporting over 1,000 MOD locations across the UK and Europe. With more than 1,250 security-cleared employees, our teams deliver resilient, compliant and mission-critical solutions in highly secure environments - at scale and with absolute operational confidence .

From higher education campuses to specialist research facilities, we deliver engineering solutions that support learning, innovation and future growth. Our extensive use of offsite manufacturing minimises on-site disruption, allowing teaching and research activities to continue uninterrupted.

We deliver technically complex engineering solutions across major infrastructure and utilities programmes including water. Leveraging BIM, digital design and offsite manufacture, we create bespoke solutions designed to budget and delivered with minimal disruption - often in fully operational environments where continuity is critical .

We engineer environments that directly support patient outcomes, clinical performance and staff wellbeing. From specialist ventilation and infection control systems to resilient building services for acute care, we understand the demands of live healthcare settings.

Our nuclear engineering heritage dates back to the 1950s, including contributions to Calder Hall, the world’s first full-scale nuclear power station. Today, we continue to deliver precision engineering services across the nuclear lifecycle, operating to the highest safety, quality and regulatory standards.

We deliver flexible, high-quality engineering solutions across retail, leisure and hospitality environments where customer experience, brand standards and operational continuity are critical. From flagship retail destinations to hotels and entertainment venues, we create efficient, adaptable spaces that perform reliably under constant use.

We support major transport infrastructure programmes that improve passenger experience while keeping networks moving. Through careful planning and innovative offsite construction methods, we minimise disruption in some of the UK’s busiest transport hubs.
We use advanced digital design, simulation and 3D modelling to drive better outcomes from the earliest project stages. This enables enhanced coordination, early risk mitigation and informed decision-making, giving clients clear visibility and confidence throughout the project lifecycle.
Our digital-first approach underpins efficient delivery across highly complex environments, from healthcare and transport to nuclear and defence.
By combining mechanical engineering design services, offsite manufacture and installation within a single delivery model, we improve build quality, shorten programmes and reduce on-site risk. This integrated approach enables repeatability where appropriate, while retaining the flexibility required for bespoke, technically demanding projects.
Through in-house integrated delivery we're able to support greater programme certainty, improve coordination and deliver consistent outcomes across complex, multi-site and fast-track environments.
Operational excellence is fundamental to how we deliver. Our teams operate effectively in live, regulated and mission-critical environments, maintaining continuity while executing complex works.
Through disciplined planning, experienced leadership, rigorous quality management and robust governance, we ensure predictable delivery even where constraints are high and tolerance for disruption is low.
We adopt and apply soft landings principles to ensure a smooth transition from construction to operation. By working closely with clients during the final stages of delivery and early occupation, we support building users in understanding and optimising their new assets.
This approach reduces operational risk, improves building performance and ensures engineering systems deliver as intended from day one.
Our mechanical engineering consultancy services prioritise integration, aligning with clients, designers and supply chain partners on a shared project vision. Through collaborative planning, clear leadership structures and defined accountability, we foster an open, high-performing delivery environment.
Our one-team approach enables faster decision-making, more effective problem-solving and outcomes that are aligned to the project’s long-term objectives.
Our focus extends beyond capital delivery to whole-life performance. We design engineering solutions that improve energy efficiency, operational resilience and long-term asset value.
This value-led mindset is strengthened by our local delivery teams, sector-specific expertise and close client engagement, ensuring solutions are practical, efficient and fit for purpose.
Our Group-wide Responsibility and Impact Strategy sets clear long-term ambitions across low carbon, social value, sustainable growth and creating an inclusive and diverse place to work.
We recognise the influence engineering has on the built environment and take responsibility for delivering solutions that support our clients’ sustainability goals while creating positive social and environmental impact.
As an independent, family-owned business, we take a long-term view. Our financial stability enables sustained investment in people, digital capability and offsite manufacturing, giving clients confidence in our ability to deliver today and support assets well into the future.

For more than 25 years, we've been shaping the future of offsite manufacturing. We now operate from five UK facilities with a footprint of over 125,000s q ft.
Our hybrid delivery model is built on a foundation of standardised, repeatable products, providing consistency, efficiency and certainty at scale. From this baseline, we apply targeted customisation through OSM Consult, utilising expert consultants and engineering oversight, ensuring every solution is designed to meet project requirements. The result is a balanced, industrialised approach that combines the reliability of standardisation with the flexibility needed to deliver complex, high-performance outcomes.
Every project tells a story of collaboration, technical excellence and delivery at scale. Discover how we help our clients overcome complex challenges, improve performance and create long-term value through our projects.
