Rising line rental prices mean UK consumers are being forced to pay more for their TV, phone and broadband bundles.
Research conducted by uSwitch.com shows the average cost of renting a landline has increased by more than a quarter (29 per cent) since 2011.
And each of the main fixed-line service providers - BT, Sky, TalkTalk and Virgin Media - are planning to further increase line rental costs in the near future.
BT, Sky and TalkTalk are putting their prices up at the start of December, while Virgin Media subscribers will be hit with higher costs in February 2015.
Costs are set to increase by an average of six per cent - 4.7 per cent above the current rate of inflation. This means Brits will be paying, on average, £42 per year more than in 2011 for landline services.
Ewan Taylor-Gibson, broadband expert at uSwitch.com, said rising landline costs are "an industry-wide problem that’s getting worse, year after year".
"Our landlines are, in most cases, a requirement for home broadband, so many of us have little choice but to pay the increase," he stated.
"It’s all the more irritating when our hardly-used home phones are sitting there, gathering dust."
Mr Taylor-Gibson said service providers are "working hard" to keep broadband prices as competitive as possible, but additional costs are creeping into other areas.
"The price hikes especially affect those who tend to be less regular home internet users, such as the older generation, who are forced to swallow the higher cost without seeing any of the benefits," he stated.
In many cases, consumers can reduce their line rental costs by paying 12 months' in advance. Savings of up to £80 per year are possible with some broadband providers.
