Cable broadband giant Virgin Media Business has promised to deliver superfast speeds of up to 1Gb to its business customers.
The provider's Big Red Internet "gives companies all the bandwidth they need, without restrictions or extra charges," said Virgin Media Business.
A study by the company said that 69% of IT managers compared restrictions on business bandwidth to "shackles" on their companies.
45% also added that "problems caused by restricted internet connections were the single biggest drain on their time".
The provider is using its fibre optic cable network to offer two new business broadband packages, with speeds of up to 100Mb broadband for smaller businesses or 1Gb connections for companies needing more bandwidth.
Mark Heraghty, Virgin Media Business managing director, said: "In 2010 telecom providers shouldn't be acting as gatekeepers to what British businesses need in order to innovate and grow - bandwidth.
"Whereas other providers often constrain the bandwidth made available to businesses, Virgin Media Business can take advantage of the vast capacity on its national fibre optic network.
"So by removing bandwidth restrictions on business internet, we're liberating British organisations from one of the single biggest factors holding them back today."
Virgin Media already offers speeds of up to50Mb broadband to home internet customers, with plans to launch an even faster 100Mb package by the end of the year.
However, Virgin Media's cable network is only available to just over half of the UK.
BT broadband is currently rolling out its own fibre network, which will cover two-thirds of the country by 2015. But because it still uses copper wire in its connections, the new BT Infinity packages will offer speeds of up to 40Mb broadband.
