Broadband companies who run their own networks have brought competition and lower prices to customers.
Broadband bills have dropped by more than 50% since 2005, thanks to more than 7.5 million local loop unbundled (LLU) lines, telecoms regulator Ofcom has revealed.
BT infinity was the main option for getting most people online in the past, but now consumers have a choice of over 30 different providers offering local loop unbundled (LLU) broadband and phone packages.
Ofcom began allowing competitors to install their own equipment into the local telephone exchange in 2005 - a process known as "local loop unbundling". And Ofcom noted: "greater competition has meant lower bills for consumers."
There were 123,000 unbundled lines in 2005, but this increased to 7.53 million by January 2011.
The regulator added: "Ofcom's research shows that there are now over 19 million broadband lines in the UK. Of these, more than 70% are provided by companies other than BT, many on the basis of unbundled lines," it added.
