The telecoms giant is increasing prices by up to €84 a year and it is ending some of its older mobile phone plan deals.
The company confirmed that broadband prices are rising by between €5 and €7 a month from November on wards.
In a statement, the company said: “This adjustment is in response to increased operational costs, primarily due to the rise in wholesale prices.”
It added that the price of its recently added TV, broadband, home and mobile package will not be affected by the increase.
A spokesperson said: “Customers have the option of changing their plan and should contact a Vodafone customer service agent for details.”
Vodafone is also ending some low-priced mobile phone plans.
“A small number of customers who are currently on old, outdated plans are currently being moved to the new Vodafone Red 30 Day plan as Vodafone upgrades its internal systems,” a spokesperson said.
“Vodafone has been in contact with affected customers to inform them of the move.”
Managing director of price comparison site Switcher.ie, Eoin Clarke, said: “In June, Open Eir confirmed an increase of €3.50 a month in its fibre broadband prices for wholesale customers.
“Now, we’re seeing Vodafone raise its prices by between €5 and €7 per month as a result of costs associated with this wholesale hike – although not all customers are affected.”
He warned that we could see price increases from other broadband providers too.
Sky, Eir and Virgin have already increased prices for their services this year.
