The Post Office has switched its managed broadband and phone service to a new network, it has been revealed.
Subscribers will now receive broadband and calls over Fujitsu and TalkTalk's unbundled solution, rather than through BT Wholesale.
The firms are offering a "next-generation network broadband experience combined with enhanced customer care and billing solutions".
As such, the Post Office will now be able to offer faster download speeds to end-users.
Dido Harding, Chief Executive of TalkTalk, said the firm is "very proud" of the wholesale opportunities it offers strategic partners.
"We are delighted to be working with the Post Office and Fujitsu to provide next-generation broadband and telephony services in line with our long term strategy for leveraging the scale of our network and growing TalkTalk Business," she stated.
"Our super-fast, highly resilient network reaches over 92 per cent of the population in the UK enabling the Post Office to offer great value products to more people, more of the time."
Duncan Tait, Chief Executive of Fujitsu UK & Ireland, said that as a partner to the Post Office since 1996, the firm had listened carefully to its requirements and aspirations.
"We worked with the customer to leverage Fujitsu’s IT and telecommunications innovation with the best-in-class partners in the UK market," he stated.
Mr Tait commented that Fujitsu is "very excited" to be involved in this project, which will see Post Office customers enjoy enhanced broadband services.
