The firm said the change of name reflects its recent growth to around 36,700 people globally with 7,100 based in the UK. The new name will cover more than 85 small and mid-sized to large companies that have previously come together.

Mouchel Consulting, which was acquired in October 2016, will also become WSP in July when it is fully integrated with the wider business.

The name currently used on the Toronto Stock Exchange will remain unchanged as WSP Global Inc.

The combined WSP | Parsons Brinckerhoff and Mouchel Consulting business has been involved in many high profile UK projects including the Queen Elizabeth University Hospital in Glasgow.

Mark Naysmith, UK CEO, said: “WSP is a successful story of global growth. We have decided to change our name after speaking to our people and our clients extensively. Our conversations with clients showed they have a genuine curiosity about us and the services we provide. For our 7,100 people in the UK, being WSP will allow us to focus on our shared future, combined talent and common vision as one of the country’s fastest growing engineering professional services consultancies.

“From the Shard to Alder Hey Children’s Hospital, Crossrail and HS2 to the Smart M1 Motorway, and Exeter’s supercomputer to Glasgow’s Athlete’s Village, we are proud of the contribution we make to societies throughout the UK. As part of a 36,700 strong global consultancy, we will continue to deliver for all our clients the same legacy: great places for people to live, travel, work and enjoy.”
