BT is set to raise call charges by nine per cent from 28 April, it confirmed today.
The increase will result in UK landline calls going up from 7p a minute to 7.6p a minute.
The price for the line rental will also go up by 30p, reaching 13.90 a month, and the setup fee for landline telephones will rise to 12.5p.
Some eight million BT customers have been informed of the fare changes via letter but a further four million have yet to be contacted.
In a public statement, BT said the impact of the foreseen price changes would be "minimal."
"We are happy to discuss with customers the savings they could make with Line Rental Saver and an inclusive calling plan," BT added.
BT claimed not all its services would increase in price, with some costs staying the same and a select few falling. Amongst the latter is the Anytime calls package, which will go down from 5 to 4.70.
