Check Safety First has acquired shares in Argent Health and Safety and plans to grown the business.
Argent will continue to operate as a separate limited company within the Check Safety First group, under the stewardship of managing director Claire McKinney.
Stephen Tate, chairman of CSF said: "Argent will also now benefit from Check Safety First group resources, enabling further growth and strengthening of the Argent business model, not only in the UK but in other key EU travel markets.
"We are delighted to welcome the Argent team to the Check Safety First group."
Check Safety First delivers security, hygiene and safety risk management systems to hotels worldwide through its operating brand Cristal International Standards.
Argent Health and Safety provides tour operators and bed banks with a full due diligence health and safety auditing service for thousands of hotels annually.
Tim Oliver, chairman of Argent, added. "We believe that it has never been more important than now to reassure the travelling public that they can expect good standards and a safe environment whenever they travel around the world.
"Working closely with Check Safety First we now have an increased capability and a huge depth of resource which will enable us to deliver our audit programme alongside an enhanced hygiene programme, which is something our clients have been looking for."
