More than half (69%) of UK internet users would change broadband supplier if offered a cheaper package, according to a survey by ICM Research.
The survey of more than a 1,000 internet users found that 51% of respondents would move to a supplier that could offer faster connection speeds.
Poor customer service by broadband suppliers was cited by 36% as the reason for considering switching to a new supplier.
However, the survey commissioned by BroadbandChoices.co.uk also found that even though consumers could save around £100 a year by changing broadband supplier, 29% said they would not be bothered to switch, and 43% said they were worried about getting tied into a lengthy contract.
Michael Phillips, product development director at BroadbandChoices.co.uk, said if consumers shopped around, they could save money without entering into a punitive long-term contract.
