The new London office will focus on securing business opportunities within the M25 and South East region.

Speaking about the merger, Arthian Chief Executive Officer, Derek J. McNab (former Managing Director, Mabbett), said: "We are delighted to combine the talented teams at Mabbett and IKM, to create Arthian. The merger will bring huge benefits to the clients of both companies, not to mention the new opportunities that the enhanced service offering and geographical reach will bring to Arthian

"The multi disciplined nature of our combined services will offer an immediate benefit to our client base and the scale of the merged entity will allow us to enter new markets and take on larger contracts.


"Having enjoyed long, successful histories as Mabbett and IKM, we look forward to an exciting future together ahead as Arthian, which we will establish as the premier mid-sized consultancy serving the UK and ROI markets."

Speaking about this significant merger, Arthian Senior Director, Liz Copland (former Director, IKM), commented: "It's exciting to announce that we have joined forces as Arthian and are able to bring our clients an expanded service portfolio to support their business needs. Our geographical reach has significantly increased overnight, bringing greater value to our clients with 200 consultants covering multiple sectors at strategic sites across the U.K.

"There is so much appetite and opportunity in the marketplace right now for the services we both offer, and together, we will be able to better capitalise on them. This is an exciting time for the combined staff base, too, as there will be many future development opportunities ahead as we grow."
