Can a household name for groceries help you save on your energy bills as well? The answer is yes! With Sainsbury’s Energy, you can save on not only grocery bills, but energy bills too. So, if you are thinking of switching, some reasons you might want to consider this supplier are:


  • A longstanding partnership between Sainsbury’s and British Gas.
  • Tariffs that are easy to understand and make use of with Nectar Points.
  • While they do not provide smart meters, they offer 100% renewable energy.
  • Strong customer rating on Trustpilot.

Who is behind Sainsbury's energy?

Sainsbury’s is one of the UK’s most established brands, and its foray into the energy market has been fairly successful, especially since its partnerships with British Gas in 2011, and nPower in 2019. It is the only energy supplier that offers fixed price energy tariffs with the chance to earn Nectar reward points when you switch to them. In addition to this, you can also earn up to triple the Nectar points on Sainsbury's shopping for as long as you are an energy customer.

What do Sainsbury's gas and electric tariffs offer?

Sainsbury’s Energy offers a fixed rate tariff for either gas, electricity, or dual fuel. It is known as the Fix and Reward Tariff.


The contract can be one or two years in length, and there is an exit fee of £30 per fuel if you wish to terminate your contract early. Opting for this tariff gives you the opportunity to earn bonus Nectar Points upon signup, as well as extra Nectar points every time you shop at Sainsbury’s. Additionally, you can enjoy 100% renewable energy, plus, access to the Warm Home Discount in case your home is eligible.


The one thing to note about this energy supplier is that there is a standing charge that applies to the tariff. Additionally, payment can only be done by monthly direct debit.  You can manage your account via the website or the mobile application.
