The hand-over took place at BMW dealership, Williams Rochdale.
Alphabet and Williams negotiated the new fleet deal, which sees Global's roster of Renaults completely replaced by BMW 3 and 5 Series saloons and Tourings.
Mark Bedward, managing director of Global Telecoms and Technology, said, “We want to recruit and retain the very best staff so our customers will receive the highest level service from the best professionals the industry has to offer.
"Benefits such as impressive cars are a part of the overall package and our people are very well looked after.”
Richard Schooling, commercial director of Alphabet, said: "Global Telecoms and Technology’s decision shows that the company car remains as valuable as ever to employers. BMW cars' strong residual values and efficient running costs make an all-prestige car fleet a completely cost-effective proposition."
