Carbon Efficient Buildings
By integrating fit-out and technical maintenance expertise, we design buildings for long-term value and help optimise performance throughout their lifecycle, supporting our clients’ energy transition.
Batteries and Gigafactories
We bring deep engineering expertise across power systems, controls, and high-integrity environments, supporting the delivery, operation, and optimisation of gigafactories and battery facilities
EV Charging Infrastructure
Our integrated engineering capability spans power, grid connections, and digital controls, enabling us to design, deliver, and maintain safe, resilient, and future-ready charging solutions.

Power Infrastructure

We are supporting the transformation of the UK’s power infrastructure through our work on the electricity network, our innovative POC-MAST™ solution, and our expertise in the nuclear sector. We have extensive experience working in highly regulated, safety-critical environments, supporting engineering delivery across construction, commissioning, long-term operation, and decommissioning.

Decarbonising the UK Grid
As the UK energy system transitions to low-carbon generation, the electricity grid must evolve to meet rising demand, integrate decentralised assets, and manage increasing complexity. We provide specialist capability in high-voltage engineering and power distribution, supporting grid reinforcement, modernisation, and integration.
Nuclear New Build
Our expertise in nuclear standards, quality assurance, and full asset lifecycle management enables us to help clients deliver infrastructure that is safe, resilient, and built for the long term.
POC-MAST™
Suitable for both new connections and network upgrades, it reduces programme risk, cost, and disruption while maintaining safety and network integrity.

Modern Methods of Construction

We're championing the adoption of modern methods of construction through our dedicated offsite manufacturing capabilities. We apply our offsite manufacturing expertise to deliver repeatable mechanical and electrical assemblies, enabling components to be designed once and deployed across multiple projects. By integrating design, engineering, and manufacturing expertise, we streamline delivery processes, improve quality, and reduce embodied carbon, helping clients achieve more efficient and sustainable outcomes across their projects.

OSM Assemble
By assembling systems in controlled factory environments, we improve efficiency, reduce waste, and minimise carbon-intensive site activity while supporting faster installation and improved quality.
OSM Fabricate & Ventilation
We utilise advanced fabrication and ventilation manufacturing capabilities to produce high-quality mechanical, structural, and ductwork systems in controlled environments. Through standardisation and precision manufacturing, we optimise material use and reduce embodied carbon while delivering consistent, high-performing systems that support low-carbon construction.
OSM Consult
We provide early-stage consultancy to help clients maximise the benefits of offsite construction from the outset. By guiding designs towards standardised solutions and reducing unnecessary bespoke elements, we reduce waste, rework, and inefficiencies while supporting lower embodied carbon outcomes.
