A study by Moneysupermarket shows over two-thirds of adults do not use the same provider for broadband, TV and home phone, meaning they could be wasting £40 every month on standalone products.

Despite triple bundle costs dropping in the last 12 months, the survey shows the majority of those who do have bundled deals haven’t reviewed the costs for at least a year. Three in 10 said they reviewed their deal over a year ago and 23% nine months ago.

Rob Barnes, head of broadband and mobiles at Moneysupermarket, said: “One of the advantages of bundled deals is the amount of money people can save. With providers fighting for new customers and dropping their prices, customers can easily swap onto a better deal.

“Dealing with different providers and organising various bills can be a nightmare. However, with bundled deals you’ll receive just one bill each month making it far easier to keep an eye on expenses. Also if something goes wrong you only need to ring one provider.”

“Over the next year I think bundled packages will continue to dominate the TV, phone and broadband market. We’re likely to see prices become more competitive as broadband providers jostle for greater market share. This will be a huge benefit to customers as they can save hundreds of pounds by bundling products together.”

Moneysupermarket’s top tips for bundling include checking if there is a download cap on the broadband contract, checking the internet connection speed and looking for a deal with free phone calls to save even more money.
