Blackrow Group and On Line Group Ltd (trading as OLG) have announced a landmark strategic partnership, uniting their capabilities to provide integrated engineering solutions across the UK’s leading industrial regions.
This significant development comes in the wake of Chancellor Rachel Reeves’ 2025 Spending Review, which pledges major investment in energy and transport infrastructure. Against this backdrop, the collaboration between Blackrow and OLG is both timely and transformative, designed to support the delivery of complex, large-scale projects at pace.
A Combined Legacy of Excellence
Together, Blackrow and OLG represent over a century of industry expertise. Their combined annual revenue exceeds £75 million, and they employ a workforce of more than 600 skilled professionals. With operations spanning six key sites – including Grimsby, Immingham, and Leicester – the partnership offers over 250,000 square feet of manufacturing space within the UK’s most prominent industrial hubs.
This alliance enables seamless integration across every project phase: from design, engineering, and fabrication to installation and mechanical services. It creates a truly end-to-end solution for clients seeking reliability, technical precision, and nationwide reach.
Investing in the Future Workforce
A shared commitment to industry longevity is at the core of this partnership. Together, the two organisations support over 50 apprentices across six disciplines, demonstrating a proactive investment in skills, training, and the next generation of engineering professionals.
Both Blackrow and OLG are actively pursuing ISO 44001 certification – an internationally recognised standard for collaborative business relationships. This formalises their approach to partnership working, embedding client value and shared success into the foundations of their operations.
Leading on Sustainability and Innovation
Blackrow Group continues to lead the way in its drive towards carbon net zero. Through initiatives that prioritise energy efficiency, renewable energy adoption, and continuous process improvement, the company is making measurable strides in sustainability.
Its engineering expertise extends across the renewables sector, having delivered components and systems for wind, solar, and biofuel energy infrastructure. These capabilities position the new partnership at the heart of the UK’s green industrial transition.
With both businesses deeply rooted in the Humber region – an area rapidly emerging as a focal point for decarbonisation – the partnership is uniquely placed to support flagship government-backed projects in hydrogen, carbon capture (CCUS), and clean energy.
Under the new alliance, Blackrow will lead on installation and mechanical services, while OLG will deliver design and project management – ensuring a cohesive and fully coordinated delivery model from concept to completion.
Leadership Perspectives
Tony Booker, Managing Director of Blackrow Group, commented:
“This is a momentous and proud milestone for Blackrow Group. At the heart of our ongoing success lies collaboration, which is critical to achieving the ambitious growth we have set for the future. This partnership enhances our ability to deliver engineering excellence not only within the Humber region but across the UK, providing unmatched value to our clients.”
Barry Taylor, Managing Director of OLG, added:
“This is a significant and proud moment for OLG. The aligned and complementary services this partnership offers create synergies and added value for our clients. We believe this alliance will strengthen our competitive edge and support our long-term vision for growth, underpinned by the dedication of our exceptional teams.”
A Partnership with Purpose
This partnership marks a new chapter in UK industrial engineering – one defined by collaboration, sustainability, and shared growth. It reinforces the critical role that joined-up thinking plays in tackling the scale and complexity of upcoming infrastructure demands.
Above all, it represents a joint investment in people, in place, and in progress – delivering not just for the businesses involved, but for the wider communities and industries they serve.
