Selectra UK is not affiliated with this energy provider.

M&S Energy partners with Octopus Energy to provide gas and electricity to domestic customers. The company claims to offer ‘feel-great energy’ that is affordable and 100% renewable. Read on to find out more about what this energy supplied can do for its customers.

About M&S Energy

M&S Energy provides energy to UK households through what’s called a ‘white label’ agreement with Octopus Energy. In this type of partnership, the latter actually supplies the energy that is then sold under the M&S (Marks & Spencer) brand name.

When Marks and Spencer decided to enter the energy industry in 2008, they originally partnered with SSE. In 2018, the company severed its ties with SSE and announced a new agreement with Octopus Energy.

Through Octopus, M&S Energy has been able to provide 100% renewable energy at a more competitive price than before. The company is able to cut costs by managing all accounts online. However, since Octopus Energy tariffs are generally cheaper, M&S Energy customers are basically paying a higher price for the same energy supply.

Tariffs and prices

M&S Energy does not have a wide range of tariffs to choose from. The provider offers just two energy tariffs at one time: a fixed tariff (where prices are guaranteed for the length of the contract) and a variable tariff (in which energy prices can fluctuate).

All customers are required to provide monthly meter readings, and bills are paid via a monthly direct debit. If you have a traditional prepayment meter, you will not be able to sign up for a tariff with M&S Energy.

Below, we break down the current M&S Energy tariffs and prices for dual fuel customers. Our calculations are based on the average annual consumption rates for a medium-sized household in London, which is 3,100 kWh of electricity and 12,000 kWh of gas.

Fixed tariff

The current fixed-rate tariff that M&S Energy offers is called the M&S Energy 12M Fixed March v2 tariff. If you get an energy quote on the M&S Energy website, this is the tariff that will be presented to you.

After signing up on this plan, customers are guaranteed that their unit rates and standing charges will not change for 12 months. New customers even get an M&S e-gift card when they switch to this tariff from a different energy provider.

While this tariff is currently cheaper than the provider’s variable tariff, there are many other energy companies with much more affordable options.

Unlike most fixed-rate tariffs in the UK, this tariff does not have an exit fee. Customers can change to a different tariff or provider without having to pay to cancel the agreement.

Cost type Price
Electricity unit rate 14.784p per kWh
Gas unit rate 3.1815p per kWh
Electricity standing charge 20.7375p per day
Gas standing charge 20.622p per day
Total estimated cost per month £82.59
Total estimated cost per year £991.05
Exit fee £0

Variable tariff

The M&S Everyday Energy tariff is the provider's deemed variable tariff. Customers are automatically put on this tariff if they move into a property without setting up a formal agreement with M&S Energy. You can also find yourself rolled onto this tariff if you M&S Energy fixed tariff comes to an end and you do not select a new tariff to go on.

Since this tariff also has no exit fee, you can move to a different tariff or provider without being penalised if you find a better option.

Smart Meters

electric meter

M&S Energy uses smart meters that are made by the business Secure. If you switch from a different provider to M&S Energy, your smart meter will lose its smart functionality if it is not a Secure smart meter. The meter will still work — it will just function as a traditional meter and you will need to submit your meter readings manually.

Other companies that use Secure smart meters are OVO, E.ON, Bristol Energy, First Utility and Utilita. If you had a Secure smart meter installed by one of these providers, your smart meter will be compatible with M&S Energy.

If you would like to have a smart meter installed, you will need to contact M&S Energy. Since the provider is overbooked at the moment for installations, it may take some time before you are able to get an appointment.
