Small increases in phone and broadband bills "could have a big impacts on family finances," according to the chief executive of Citizens Advice.
Speaking after BT announced that prices for phone and broadband packages will rise by up to 6.5%, Gillian Guy said: "Inflation-busting price rises are bad news for cash-strapped households."
She added: "With the extremely tough pressures on household budgets at present and wages that will continue to stay way below inflation, even a small increase in phone and broadband bills could have a big impact on family finances."
Utility providers need to be up front with their customers about when prices are going up and where there are savings to be made, she said, adding that Citizens Advice has dealt with more than 62,000 telephone and broadband debt problems in the last 12 months.
