Ovo

British Gas, Ovo Energy and Utility Warehouse forcibly installed many more prepayment meters than their competitors, the energy regulator has found - and all suppliers have been warned this tactic must be a last resort to recover debt.

Ovo Energy is increasing prices for around 180,000 customers on its standard variable tariff from today (Friday 8 June), MoneySavingExpert can reveal.

The energy regulator is to investigate whether Ovo Energy gave some of its customers inaccurate information relating to how much gas and electricity they'd used.

Smaller energy suppliers are continuing to outperform the big six when it comes to customer service, a new poll of MoneySavingExpert.com users reveals, despite those at the bottom of the table significantly upping their game in the past six months.

Ovo has become the latest energy supplier to hike prices, with 94,000 customers on its dual fuel standard tariff set to see bills rise by an average of 5% from January.

Co-op Energy has become the second small supplier to raise prices as wholesale energy costs surge.

Co-operative Energy has blamed ongoing problems with its new IT system as the reason why it was the most complained about energy provider in the third quarter of the year.

Co-op Energy was a customer service darling last December, with 63% of its customers rating it great and just 7% rating it poor. But in a staggering turnaround, just six months later over half of its customers (56%) rate its service as poor and just 22% rate it great. 

Small energy supplier Ovo has today launched an app, which enables its prepay customers to top up their energy without leaving their homes.

Northern Ireland's main electricity supplier has cut bills by nearly a tenth for all households after falls in wholesale gas prices.
