Pinergy have announced a price increase from next month.

Accumulated losses at the firm behind the Pinergy brand more than doubled to €5.7m in 2014 as the energy firm continued its expansion phase by doubling its customer base.

A series of advertisements for energy company Pinergy fronted by Irish rugby captain Paul O’Connell have been banned for “misleading” consumers.

Hundreds of thousands of people switched their electricity and gas provider last year to try and cut the costs of their utility bills.
