And become UK's 2nd largest ISP Sky (BSkyB) is to buy Telefónicas UK fixed-line broadband and telephony business for up to £200 million, the companies announced early on Friday. If the deal is approved it will make Sky the UKs second biggest broadband provider. The deal, which is subject to regulatory clearance, should conclude in April. Customers will then be moved off the O2 and BE Broadband brands and become Sky customers. Telefónica will get £180 million for its broadband business, plus an extra amount up to £20 million upon the successful delivery and completion of the customer migration process. Heres what Sky CEO Jeremy Darroch had to say: Sky has been the UKs fastest-growing broadband and telephony provider since we entered the market six years ago. From a standing start in 2006, we have added more than 4.2 million broadband customers. The acquisition of Telefónica UKs consumer broadband and fixed-line telephony business will help us accelerate this growth. We believe that the O2 and BE consumer broadband and telephony business is a great fit, with customers used to high-quality products and strong levels of customer service. We look forward to welcoming these new customers to Sky and giving them access to our wide range of high-quality products, great value and industry-leading customer service.
