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.

SSE has cut switching times to 17 days from today, while First Utility has confirmed it will introduce faster energy switching from 10 November ahead of the New Year's Eve deadline given by Ofgem.

MoneySavingExpert.com has today launched what's likely to be the largest collective switch to date and we've negotiated tariffs cheaper than the cheapest energy deals using the power of the 9m recipients of our weekly email and the 1.2m members of Cheap Energy Club.

Ofgem has written to the big energy suppliers demanding they take action on the poor handling of complaints after the regulator found the average customer had to contact their supplier six times before an issue was resolved.

Ovo Energy has topped our poll for customer service for the second time running with more than 80% of its users rating its service as "great". At the other end of the scale, Npower remains last for the third poll running.

Energy prices are unlikely to rise before the end of the year but there is a threat of increases over the next few years, according to predictions from industry experts.

If you're an E.on customer, you could be due a share of a £20 million payout after the energy giant was found guilty of mis-selling on a massive scale by regulator Ofgem.

The big six energy companies could face a full-scale investigation into whether they are preventing competition in the market and making excess profits, reglator Ofgem has announced.

Energy minnow First Utility has undercut its rivals by launching the market's cheapest tariff – but is it worth switching to?

If you've signed up to a fixed price energy tariff in the past few years, your bill could be about to soar as 15 deals are ending soon. But you can beat the hikes – if you act now.
