Ovo Energy hikes bills by £135 a year
It is also removing the online discount from its variable plan.
The firm blamed an increase in wholesale energy costs, which it said had risen by over 15% since June, for the price rise.
The changes to its standard variable tariff – known as Simpler Energy tariff – mean customers who currently receive the online discount will pay £1,225 a year, up from £1,090 – a 12.4% increase. Customers who don’t get the online discount will pay £1,225, up from £1,150 – a 6.5% rise.
