British Gas and EDF have become the last of the big six energy firms to announce a price drop this year, cutting the price of gas next month by 5.1% and 5% respectively. But even after the cuts their standard tariffs will cost £100s more than the market's cheapest, so check now to see if you can switch and save.

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. 

Energy firms are facing increased pressure from the Government to pass on a fall in wholesale costs – the price providers pay for energy – to consumers by slashing household bills.

Customers of the big six energy suppliers are paying up to £234 a year too much for their gas and electricity bills, a competition probe has found. But MoneySavingExpert.com has been saying for years that households could save hundreds by switching.

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

Ovo Energy has today announced it's cutting gas prices by 10.4%, which is more than double the recent price cuts revealed by the big six energy providers. But households can still save more by switching.

EDF Energy has today become the last of the big six energy providers to announce a gas price cut this year, but prices will only fall by a tiny 1.3% and not until 11 February.

SSE has today become the fifth of the big six energy providers to announce a gas price cut this year, but the 4.1% drop won't take effect until 30 April.

Customers of electricity provider iSupplyEnergy will no longer be blocked from switching if they don't tell it they're moving elsewhere, following concerns flagged by both customers and MoneySavingExpert.com.
