Household spending on entertainment bundles has increased to record levels, a national review of internet users' spending habits has shown.
Vision and Value 2014 - an examination of television, broadband and home phone usage among consumers who choose to bundle the services - found that monthly spending on bundles has increased by £1 since 2013, costing each household an average of £50 per month.
This equates to an overall national spend of £3.3 billion - the highest it has ever been.
The report also found that almost one in five UK bundle users is spending an additional £10 per month for online TV subscriptions.
But nearly two-thirds (62%) of those questioned said they have no idea how much internet data they actually use, while almost a third of respondents (29%) do not know what capacity they are paying for.
The cost of TV "wastage" - the amount spent on paid-for channels that are going unwatched - has decreased since last year. With the cost of TV entertainment within a bundle averaging at £22 per month in 2014, households are spending £195.35 annually on unwatched TV channels.
The report was issued by the Post Office and Freeview.
Hugh Stacey, spokesman for Post Office HomePhone and Broadband, said: "The Vision and Value report has once again highlighted the importance of understanding the needs of your household when it comes to choosing the right TV, home phone and broadband package.
"Bigger isn't necessarily better. Even though consumers are accessing greater levels of content online, most households require just a sixth of the capacity that they are paying for."
Guy North, marketing communications director at Freeview, said: "Although an increasing number of consumers are putting their hands in their pockets to pay for additional online streaming services, there is still a considerable amount of cash wasted on paid-for TV channels which go unwatched.
"People should regularly assess their viewing habits to ensure they are getting value for money from their TV service."
