The move follows the recent merger of Scottish firms Mabbett and IKM Consulting, which created one of Scotland’s largest multi-disciplinary consultancies, employing over 200 staff.

Arthian said its new Liverpool hub strengthens its position in England and expands its capacity to support clients with specialist flood risk, environmental assessment, and infrastructure services across the North West and beyond.

Derek J. McNab, CEO of Arthian, said: “Establishing our Liverpool office is a natural next step in our growth journey. As Scotland’s second largest consultancy, we’re now focused on enhancing our presence across the UK, and Liverpool gives us a strong base to support clients in the North West and Midlands.

“We’re already seeing demand for our integrated planning, engineering, and environmental expertise in the region, particularly around water management, regeneration, and sustainable development. This new office reflects our commitment to being a locally present, nationally capable consultancy.”

The Liverpool team will be led by Josh Rigby, an experienced flood risk specialist, who leads a growing technical unit focused on water and environmental resilience.

Mr Rigby said: “Our team will bring market-leading capability in flood risk assessment, drainage strategy, and climate adaptation to clients across the North of England, with more capability to come.

“From major infrastructure schemes to planning support, we’re already building a strong pipeline of work and look forward to growing our presence and team here – watch this space!”
