Almost two-thirds of UK broadband consumers remain in the dark over how much bandwidth or data they are allocated in their broadband connection.
According to research conducted by Eclipse Internet, 82 per cent of consumers understand what bandwidth is, but just 62 per cent are aware of how much they are able to use.
The study of 1,200 broadband subscribers revealed that in 72 per cent of cases, consumers were given no advice or support from their internet service provider (ISP) in order to maximise their allocation.
Clodagh Murphy, Director of Eclipse, said the findings provide evidence that "many consumers are no longer clear" about the broadband packages they are buying.
"Unfortunately, the majority of broadband advertising has become more and more dependent on clever claims about speed allocation and fair usage policies, undermined by large quantities of confusing jargon used to bamboozle users," she said.
"It's critical that all ISPs focus on a more open, honest and trustworthy way to sell internet services."
Eclipse Internet triumphed in the Best Business Email and Best Business ISP categories at the 2008 Internet Service Providers' Association awards.
