A trusted and established partner

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.

Offsite Manufacture -07

Engineering capability at scale

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.

OPERATING ACROSS CRITICAL SECTORS

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.

Engineering that delivers certainty

Technology-enabled engineering

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.

Integrated design, manufacture and installation

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

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.

Soft landings

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.

Collaborative, one-team delivery

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.

Delivering long-term value

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.

Responsible, future-focused delivery

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.

Independence that delivers confidence

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.

INDUSTRIALISED CONSTRUCTION

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.
