Providers renting BT's telephone lines to provide broadband could see prices increase in the near future following Ofcom's drafting of new tariffs.
The regulator has proposed the pricing changes in response to BT's claims that costs have increased and that local loop unbundlers are providing added competition, reports the Times.
Providers using BT lines for broadband and telephony services could see an 11 per cent rise, while those involved solely in broadband provision are set to pay four per cent more.
Ofcom says that the new tariffs "are designed to promote continued competition in the provision of voice and broadband services and to ensure that Openreach has the appropriate incentives to invest in delivering the services required by customers".
The consultation also projects how pricing may change over the next four years, with the recently-set out hikes planned to take effect by April next year.
