About Keltbray

We have spent 50 years shaping our future and the built environment, building a reputation as a trusted engineering partner to leading private and public sector clients. Five decades of solving construction’s most complex engineering problems have given us an unparalleled depth of capability, technical judgement and expertise.

Our Expertise  

We are engineering-led, not generalist. Our multi-disciplinary teams have the specialised plant and skills to deliver standalone services and integrated solutions. 

Our services span the full breadth of the construction value chain: from pre-construction and design engineering consultancy, through enabling works, piling and ground engineering, to demolition, decommissioning, remodelling, structures and specialist construction delivery. We provide integrated engineering expertise at every stage of a project’s life cycle. 

Our Clients 

Keltbray operates across highly regulated sectors — including energy, utilities, petrochemicals and nuclear — and supports the infrastructure, including data centres and transport, that keeps the UK moving and growing.  

Complex delivery depends on strong relationships. That means building trusted partnerships, putting clients first, and consistently delivering on our promises. We lead through innovation to deliver with pride.
