An Adare SEC spokesperson said Viquerat left his position this month as sales and business development director.

He joined the business in 2012 and was responsible for leading and driving the sales and business development teams, and delivering organic growth.

"We’d like to thank Martyn for all his hard work at Adare SEC,” the spokesperson said.

Barry Crich, who joined in 1997 as operations director at the company’s Huddersfield site – previously Adare Halcyon – will leave his current position as chief operating officer on 30 March.

Crich was part of the management buyout team of the business in 2006 and was made group operations director, overseeing the merger of Halcyon and Lexicon.

The merged companies became known as Adare Limited in 2008 and Crich was named as managing director, a role he continued to hold when the company became Adare SEC in 2015, also taking responsibility for Adare SEC’s Secure Solutions site in Redditch.

During this time, Crich was heavily involved in the firm’s acquisitions of Banner Managed Communication and Polestar Applied Solutions.

He was named chief operating officer in June 2017, as part of Adare SEC’s new structure, and continued his Secure Solutions responsibilities.

The spokesperson said: “With over 20 years at Adare SEC, Barry became the longest-serving member of the senior management team where he oversaw many changes throughout the business.

“He is set to leave the business at the end of March to pursue other opportunities. We wish Barry every success in the future.”

Crich’s departure from the business follows that of long-standing operations director Danny Narey who left the company in November 2017, serving as general manager of Adare SEC at the time of his exit, and Robert Whiteside, chairman of both Adare SEC and Adare International, who stepped down from the group at the end of last month.

The company confirmed Crich’s role will not be replaced in the immediate future.

Separately, Adare SEC has become the first communications company to become a member of the Credit Services Association (CSA) under its new Supplier Membership category.

Producing around 100 million print and digital communications on behalf of its debt collection and debt purchase clients each year, Adare has offered services to this sector for more than 20 years.

Adare SEC chief executive Richard Slee, who was appointed last year, said: “Achieving CSA supplier membership status really highlights how we see our business – at the forefront of critical customer communication solutions and continuing to deliver a quality service for our clients and their customers in this industry.

“We are proud to be part of the CSA’s supplier membership alongside being one of the first to sign up, showing our commitment to the sector as we continue to grow and innovate.”

CSA chief executive Peter Wallwork said Supplier Member status would provide Adare SEC with a range of benefits.

“It will afford them even greater visibility of the collections, debt sale and purchase market and in turn gives the CSA’s 300-strong membership greater visibility of a company that can help support their print and digital communications.”

Circa £75m-turnover Adare SEC also recently invested more than £750,000 on the installation of and upgrades to several machines at its sites.
