Ovo Energy has bucked the trend of falling gas and electricity prices by announcing up to 90,000 of its customers face a hike in their bills. But will the big six follow, which would hit millions of households?
Households are still paying substantially more for their gas and electricity than they were last summer, despite four of the big six energy firms announcing price cuts this week.
Scottish and Southern Energy (SSE) will cut gas prices by a typical 3.8% from 26 March, becoming the third major power firm to announce modest cuts this week.
