Which? Recommended Provider Octopus Energy will take SSE's place in supplying M&S Energy's gas and electricity customers from September, it was revealed today.
The new partnership plans to 'create a more progressive, digital and commercial M&S Energy' which will 'challenge the Big Six' energy firms.
It claims it won't use 'tease and squeeze' pricing, where new customers pay cheaper rates subsidised by loyal customers, and launch instead a 'responsible and transparent price model'.M&S said that it expects eight in ten customers will save money by moving to Octopus compared with their current deal. It will announce its new tariffs in August.
This comes less than two weeks after SSE and M&S Energy announced an end to their 10-year partnership.
M&S Energy is a 'white label' energy supplier. This means that it doesn't have a license to supply gas and electricity in its own right, so it partners with another firm to do this, as well as providing its customer service.
SSE has been M&S Energy's supply partner since the brand launched in 2008.
From 29 September 2018, Octopus Energy will begin supplying M&S Energy customers. Octopus Energy states that M&S Energy customers will benefit fromits digital-first approach to billing and customer service.
If you're an M&S Energy customer, you will be contacted in the next few weeks about your options.
If you're on a fixed tariff with M&S Energy, you can stay on it until the end of your contract and prices will not change.
But if you're on M&S Energy's standard tariff (called Standard Energy) and don't choose a new deal, you'll automatically be moved onto SSE's standard variable rate. These cost the same, but are among the priciest dual-fuel tariffs on the market. Octopus Energy's variable tariff is £244 cheaper per year for the average user.
Until 28 September, M&S Energy customers will continue to be supplied by SSE on their current rate. If you want to stay with SSE, it will write to customers to let them know what tariffs are available.
