LONDON, July 29 (Reuters) - British cable and mobile
provider Virgin Media O2 said it would upgrade its entire
network serving 15.5 million premises to full fibre by 2028,
stepping up its challenge to BT in rolling out ultrafast
connections.
Virgin Media 02, a joint venture that brought together
Liberty Global's cable network and Telefonica's
O2 mobile network earlier this year, said there was an
opportunity to enter the fixed wholesale market.
Chief Executive Lutz Schuler said Virgin Media was already
Britain's leading gigabit network - delivering speeds of 1.1
Gbps by the end of this year - and the upgrade would make it
even stronger for the decades ahead.
He said the cost was about 100 pounds per premise, much
lower than competing fibre build because it will use its
existing infrastructure.
Total investment, not including customer migration costs, is
about 1.43 billion pounds, given that 1.2 million homes are
already on its fibre network.
BT has set out an ambitious plan to build fibre to 25
million premises by end-2026.
Schuler said Virgin Media was not on the back foot.
"We are the speed leader, we have been growing for five
consecutive quarters," he said in an interview on Thursday.
"Customers pay a premium for speed and customers come to us,
so we are on the front foot."
He said talks on wholesale access to its network for rival
operators, such as Sky, Vodafone or Talktalk, were ongoing.
"A partner would get a speed advantage for their customers
in the short term on the cable network and long term on the
fibre network," he said. "This is definitely not a bad position
to negotiate from."
Virgin Media is extending its network, adding 89,000 homes
in the last quarter to take the total build in its Project
Lightning plan to 2.5 million.
It has an ambition to extend to a further 7 million premises
in the coming years, which Lutz said would happen once the
building blocks were in place. "Stay tuned," he said.
The company said it added 36,000 broadband subscribers in
Q2, increasing its fixed-line customer base to 5.7 million.
