Broadband wholesaler murphx has claimed it will be able to deliver improved 24Mb connections after gaining access to BT's latest network.
Following the signing of a new interconnect deal with the telecoms giant, murphx will be able to operate within BT's 21st Century Network (21CN).
The end result, murphx hopes, is that more users will have access to faster download speeds through ADSL2+ services.
Director of the company, Carl Churchill, said: "21CN currently covers 40 per cent of the UK and our investment is the start of our own migration project from BT's Colossus network over to 21CN.
"This will open up opportunities for people to have ADSL 2+ services (up to 24Mb) over BT's network."
Mr Churchill added that the new network is "considerably more cost-effective" and could increase competitiveness.
BT Broadband is currently the UK's largest high-speed internet provider, with about 4.8 million users.
