Cheap Energy Club

Ovo Energy says its two-year fixed energy tariff – the market's cheapest two-year fix on average and our overall top-pick energy deal – is to end on Saturday morning. So if you want to lock in your rate for the coming two winters with a big-name supplier offering top customer service, go quick.

Customers could be stuck on pricier energy tariffs for up to an extra three weeks as all gas switches are delayed while an IT system is updated.

Engie, one of the biggest power companies to rival the 'Big Six' energy giants for years, is launching a new 'roll over' deal which switches existing customers onto its cheapest deal when an offer ends.

Not-for-profit supplier Robin Hood Energy has announced it is hiking prices for its standard domestic gas and electricity customers by a whopping 17% on average - one of the largest increases we've seen.

Energy customers switched suppliers at the highest rate in six years in 2016, regulator Ofgem has confirmed, with 7.7 million such moves taking place.

Energy customers may have to fork out £30 more a year on their bills by 2020 to prevent winter blackouts sweeping the country, a group of MPs has warned.

British Gas and E.on are freezing the price of their standard variable tariffs until at least the end of March 2017, hot on the heels of a similar move by rival supplier SSE last month.

The Business Secretary is to investigate an allegation that the 'big six' energy suppliers are making more money out of loyal customers than they're admitting to. But regardless of the outcome of the inquiry, switching your supplier is the best way to bag big savings on your energy bills.

Concerns about energy provider SSE's approach to switching its customers – and particularly those in vulnerable situations – onto prepay meter tariffs has sparked an investigation by the energy regulator.
