With a renewed strategic vision, robust partnerships with original equipment manufacturers, and a multi-division structure, Duo Group is scaling new heights in the quarrying, aggregates, and construction sectors, underpinned by its unwavering belief that ‘There’s Always a Way’.
Duo Group (Duo) is redefining what it means to deliver excellence in the UK quarrying and infrastructure industry. With end-to-end engineering, procurement, and construction (EPC) capabilities, Duo provides comprehensive plant solutions, from concept to commissioning.
“Trust, expertise, and delivering solutions no matter how complex, that’s what drives us,” Duo Group managing director Martin McWilliams said.
“We’ve brought the business under one brand and one culture, with a clear mission: grow sustainably and deliver outstanding value. That’s what ‘There’s Always a Way’ truly means.”
Headquartered in Coventry and employing more than 150 people nationwide, Duo Group is structured across six specialised divisions.
These include
- Duo Turnkey: complete EPC project delivery
- Duo Processing: aggregate and recycling operations
- Duo Construction: civil engineering and infrastructure
- Duo Engineering Services: refurbishment, fabrication, site installations
- Duo Site Services: emergency response, maintenance and repairs
- Capital Equipment Sales: official distributor for Metso, Telestack, and Terex Washing Systems.
While all divisions play a critical role, Metso lies at the heart of Duo’s capital equipment and lifecycle solutions strategy. As the official UK distributor, Duo delivers Metso’s comprehensive range of equipment, including jaw, cone, and impact crushers, as well as modular plants, vibrating screens, feeders, conveyors, and air classifiers.
This strategic partnership was recently recognised with Metso’s 2024 Sustainability Award for Dealers, highlighting Duo’s contributions to eco-efficient projects and lifecycle service contracts (LCS).
“Our partnership with Metso is a cornerstone of our success,” Duo Group sales director Padraig McDermott said.
“Metso’s reputation for performance, innovation, and durability allows us to deliver plant solutions that maximise uptime and sustainability for UK operators. From sales to service, Duo is deeply embedded in every project phase.”
Duo’s equipment offering also includes key partnerships with Telestack and Terex Washing Systems (TWS). Telestack delivers high-efficiency, mobile bulk handling for quarries and ports, while TWS provides advanced wet processing and water management solutions for aggregates, sands, and recycling.
Beyond equipment, Duo Turnkey delivers complex plant builds as principal contractor, managing everything from civil foundations and steelwork to mechanical installation and electrical commissioning. Backed by in-house design and engineering teams, the division ensures seamless project delivery.
Duo Construction has continued to expand its civil engineering capabilities by supporting projects across roads, rail, drainage, utilities, flood protection, and brownfield remediation.
Duo Engineering Services, operating from a 25,000m² facility in Stoke, offers precision fabrication, refurbishment, and structural steelwork services. Its team provides full-scale mechanical installations, retrofits, and bespoke component manufacturing.
Duo Site Services ensures long-term reliability through rapid emergency response, planned maintenance, on-site repairs, and refurbishment, all of which are backed by national coverage.
Duo’s client portfolio includes major UK companies like Breedon, Holcim, Heidelberg Materials UK, Tarmac, Vinci, and Balfour Beatty.
Duo’s full-package offer was demonstrated by the delivery of the Bayston Hill project, one of the UK’s most advanced material processing facilities. Designed and built in partnership with Metso, the site showcases Duo’s end-to-end, turnkey strength across design, fabrication, and electrical integration, all of which are handled in-house.
Bayston Hill features a comprehensive suite of Metso equipment, including the C150 jaw crusher, GP500S, HP3, and HP4 cone crushers, among others, which support every stage of the process, from primary to advanced quaternary crushing. The setup serves as a benchmark for performance and reliability.
As the business looks to the future, Duo’s focus is on expanding into high-growth sectors, including ports, sustainable infrastructure, energy, and circular economy solutions.
“This isn’t just about growth in numbers. It’s about building smarter, greener, and more valuable solutions,” McWilliams said.
“We’re proud of our journey so far, and excited for what lies ahead. With our people, our partners, and our belief that there’s always a way, the best is yet to come.”
