From 15 November 2013, M&S Energy will be implementing changes to its pricing structure.

This follows a series of changes by SSE, who supplies M&S Energy, to its household energy tariffs and will see the average household energy bill rise by approximately 8%. The increases will not affect existing M&S Energy customers on a fixed or capped price tariff.

Last December, M&S Energy promised not to raise prices until at least the second half of 2013 and we have sought to keep energy prices at their current level for as long as possible. There are, however, now a number of factors that have made these price rises unavoidable. Firstly, the cost of buying energy for this coming winter compared with the same period last year has increased.

In addition, the cost of using the electricity and gas networks has increased, as have the costs of funding government schemes such as energy efficiency programmes and support for low-carbon energy.

We are also making some changes to our tariff structure that will ensure that live tariffs comply with certain elements of the Retail Market Review (RMR) reforms being introduced by Ofgem from 22 October, designed to make the market simpler and fairer for customers.

Rising prices don't have to mean rising bills
Using energy efficiently has a critical role to play in helping to keep bills down. Evidence over the last few years shows that the combined efforts of energy suppliers, governments, Ofgem, consumer organisations and the associated investment have succeeded in helping customers to cut their energy consumption – in the last three years alone.
