EDF

Energy customers on EDF's standard variable tariff will be hit by a second round of price hikes from June, after the firm announced it will increase dual fuel bills by an average of 7.2%. If you're on its standard tariff you're almost certainly overpaying already, so check NOW if you can switch and save.

Many of the UK's four million households which prepay for their energy will see prices drop on 1 April when a new price cap comes into force, but savings will vary hugely and at least 200,000 customers will see an increase, new figures obtained by MoneySavingExpert.com reveal.

Energy price hikes are coming. EDF has already announced it'll raise electricity prices by 8.4% in March. Many other big names have frozen prices till April, but it's highly likely we'll see rises when those promises come to an end.

We've been shouting it till we're blue in the face - if you're on a standard tariff, fixing can save you £100s. For the 66% of you on one with a Big 6 provider it's doubly important you ACT NOW. First, their prices are set to rise. On Monday smaller player Ovo Energy sneaked out a 5% rise starting in Jan - others are likely to follow.

Big six energy suppliers have been accused of keeping 1.5 million vulnerable and low income customers who receive a Government electricity discount on expensive standard variable tariffs.

Customers who move to the cheapest energy tariffs are facing eye-watering price rises once those deals end, research has found. But you can stay one step ahead of these hikes by switching suppliers.

Embattled energy supplier Extra Energy has once again been ranked bottom of the Citizens Advice performance table after receiving a record number of complaints.

If you're switching between many of the big energy providers you'll now benefit from 10 'commitments' guaranteeing a smooth and hassle-free transition – but if suppliers fail to deliver, you may still need to get the Ombudsman involved.

Some energy customers with prepay meters could save an average of almost £120/year by switching to one of the two cheapest new fixed-term tariffs.
