TalkTalk Telecom's full year results (12 months to 31st March 2016) saw EBITDA come in at £260m with TalkTalk Business revenues accounting for 30% of the Group, growing by over 5% year-on-year.
The on-net wholesale base, comprising the retail customers of businesses such as the Post Office and Utility Warehouse, grew year-on-year, as did TalkTalk Business' direct channel on-net base.
TalkTalk Business has also seen demand for data services continue to rise, with over 9,000 new high speed data lines connected and a strong pipeline of orders for the end of the year, up 23.7% year-on-year.
High speed data now accounts for 31% of the Group's corporate revenue, offsetting a decline in voice revenues (-16.2%).
TalkTalk Business MD Charles Bligh stated: "We expect to see this growth continue over the next year as we focus on strengthening our next generation network and delivering new services such as MyNet, SIP and unified communications to both our partners and direct customers."
