Excell Group's acquisition of London-based City Voice and Data and City AVS adds considerable audio and video conferencing expertise to the business and boosts revenues to over £30m.
The Group will take on both teams of field engineers and ICT consultants and a London-based service desk.
The existing senior management team will continue to run the business, led by directors Robert Boyne and Alex Smith who will report into the Excell Group board.
Darren Strowger, Chairman of Excell Group, said: "The acquisition provides a strong foundation for Excell Group in the audio visual space, and is a great strategic fit for the evolution of our business, helping drive further cross selling opportunities within our enlarged base while also providing City Voice and City AVS customers with direct access to the Group's full portfolio of products and services."
Excell Group's Finance Director Edward Pettit (who heads up the acquisition strategy) said: "We are continuing to pursue our acquisition strategy with intensity.
"The Group has strong cash reserves, meaning we are well placed to quickly capitalise on other opportunities in the near future."
Robert Boyne, co-director of both City Voice and City AVS, added: "The acquisition marks an exciting time for the teams. Excell Group will allow us to continue nurturing our expertise and resource, while also significantly growing our offering."
The acquisition follows last year's purchase of the Resource Utilities and Green Mobile customer bases.
