Martin Lewis has issued an urgent warning after it was revealed that millions of broadband and phone customers are expected to see hikes in their monthly bills.
Nearly all providers link their annual price rises to December's consumer price index (CPI) which is published in January or the retail price index (RPI) with both being near their highest rate in 40 years. The latest CPI is at 10.5 per cent while RPI is at 13.4 per cent.
BT, EE, Plusnet, and Vodafone broadband contracts saw prices go up by CPI plus 3.9 per cent. TalkTalk saw CPI plus 3.7 per cent, Shell energy saw CPI plus 3 per cent while Sky and Virgin Media contracts did not stipulate a pricing formula in the same way.
