About M&S Energy

M&S Energy launched in 2008, originally in partnership with SSE in a 'white label' agreement in which SSE handled the energy supply and customer service and Marks and Spencer simply promote the same service under their own M&S Energy branding.

However, this deal ended in September 2018 M&S Energy is now supplied by Octopus Energy instead, with a similar setup.

Their energy mix with SSE was as follows at launch:
  1. Coal: 54%
  2. Natural gas: 28%
  3. Nuclear: 1%
  4. Renewable: 15%
  5. Other: 2%

M&S Energy Tariffs & Prices

M&S Energy electricity and gas prices are similar to those of Octopus Energy except that new customers get M&S vouchers when they join. This makes M&S Energy a reasonably attractive electricity and gas supplier in terms of pricing, though it is not the cheapest by any means.

To give you a more concrete idea of pricing, here are M&S Energy’s estimated annual dual fuel, national electricity and gas costs for a home on the UK’s average electricity and gas consumption (3,200 kWh for electricity and 13,500 kWh for gas) for June 2014. Prices vary according to usage and location so this is only indicative.
