Chess has snapped up Scottish telecoms reseller NetDatatel, its fifth acquisition this year.
The Morayshire company specialises in the oil and gas industry in Scotland and its portfolio includes calls, broadband, data networking and PBX installation.
The reseller will operate under the Chess name and adds £1.5 million to the Chess Groups' turnover.
Chess Chief Executive David Pollock said: "We have acquired a business striving to become a leading telecoms supplier in the important Scottish market."
Richard Btesh, Chess Director, added: "Bringing into the fold of the Chess Group a company with a strong pool of resources in the gas and oil industries is another strong statement for our growth.
"We continue to acquire specialist telecoms, data and ICT businesses. This acquisition follows recent acquisitions Parachute IT, Integra ICT, Avenir Telecoms and The CRM business as strategic additions."
Chess has completed over 70 acquisitions in the past 10 years.
