The move will see Jubb’s 100 staff join Ridge and expand its presence in the South West and Wales.

Ridge has grown rapidly in recent years with turnover up 50% since 2022 to £140m.

The Jubb deal will add offices in Bristol, Winchester, Plymouth and Cardiff where its core services include civil engineering, structural engineering, ground engineering, and transport and environmental planning.

Jubb also has expertise in key sectors of growth for Ridge including data centres, defence and infrastructure.

Adrian O’Hickey, Senior Partner at Ridge, said: “Our interest in Jubb is driven by the excellent work its team delivers for its clients daily. As well as being established in three of our target growth sectors, its team of talented professionals are known for their technical excellence and client-focused approach. They will be a fantastic addition to the Ridge family.

“It is also worth noting that as our two businesses become one, our values and visions are well aligned. We both believe in putting our people first and we have real synergies in areas such as integrity, collaboration and a client-focused approach.”

Rob Harrhy, Managing Director at Jubb, added: “Jubb has achieved outstanding results in recent years, attracting top industry talent and securing fantastic clients.

“Joining Ridge represents a significant opportunity for us to continue delivering exceptional client experiences and outstanding service, while strengthening our future and continuing to put our people first.

“We have enjoyed getting to know the Ridge team and are confident that their multi-disciplinary approach will greatly enhance our own development and the value we provide to our clients.

“We’re delighted to play a part in the expansion of Ridge into the South West and Wales, and we look forward to consolidating their presence in key markets like data centres and infrastructure.”
