As many as seven in ten broadband customers could switch service provider during 2012, a new poll has suggested.
Research conducted by ISPreview.co.uk found that 34.1 per cent of consumers are definitely looking to switch broadband provider, up from 31 per cent at the start of 2011.
And another 34.1 per cent said they would possibly migrate to a different vendor during the course of the next 12 months.
Just 30.1 per cent of customers - potentially those who have invested in broadband bundles including TV and home phone services - said they would definitely not be moving.
The ISPreview.co.uk poll found that 55.4 per cent of consumers are happy with their broadband services, unchanged from last year.
Despite the major advances in download speeds experienced during 2011, 37.1 per cent of consumers identified these as their main gripe.
Another 19.3 per cent said service and support issues made them most unhappy, while high prices were the major gripe for 16.5 per cent.
Of those surveyed, 43.3 per cent said they were definitely paying more for broadband services than one year ago, while a further 5.4 per cent were unsure as to whether this was the case.
Some 10.2 per cent of consumers surveyed said they were most annoyed by service restrictions.
Speaking in August, TalkTalk's Director of Product Management Alex Hollingdale said it is "really easy" to change to a new broadband provider.
He explained that the new vendor takes care of migration and support issues, meaning the process does not need to be stressful for the consumer.
