Be Broadband is unlikely to launch super-fast broadband services until 2013 at the earliest, it has been revealed.
The firm - which is owned by O2 - said it is experiencing delays as it bids to launch fibre broadband services in the UK.
Be Broadband has been targeting unthrottled fibre broadband for some time, but progress on the scheme has been slower than expected.
In a blog posting, the firm said there were a number of reasons for the ongoing delays.
"But the bottom line is we're unlikely to launch a service across the Be network in 2012," the firm stated.
"Many of you told us you were prepared to wait for a fibre service from Be, so we're sorry to bring you this news and for keeping you waiting."
The company added it was looking to launch a fibre service on a limited basis later this year, combining its unshaped, unlimited network with the higher speeds of fibre-to-the-cabinet.
"It's just taking much longer than we'd like," Be Broadband added.
