Over 90 per cent of consumers think a UK-wide broadband network with a speed of 2Mb will be too slow.
Nine in ten web users said the speed is not enough to download video content, while a similar number said 2Mb is not fast enough for using streaming services such as the BBC iPlayer.
A further 83 per cent told Moneysupermarket that the speed is inadequate for online gaming, while 43 per cent think that it is not enough for web browsing.
"The majority of homes with internet have access to fast services," said Manager of Broadband James Parker, highlighting that the average broadband speed in the UK is around 3Mb.
"Despite this, the Digital Britain report seems to think 2Mb is a good enough minimum, even though this report shows a significant majority already find 2Mb too slow for many services such as iPlayer," he added.
Further figures from the study found that 76 per cent of Brits view broadband access as an essential part of modern life.
