Sainsbury’s used EDF as their supplier for all their in-store energy promotions and although their cheapest tariff is not always in the top 10 from the major suppliers they are worth getting a quote for in your area because prices are different around the country. Here are the following tariffs and rates that are currently on offer for domestic customers from the cheapest to the most expensive.

Green Tariff and Climate Balance

This supports the development of renewable energy initiatives and helps offset your CO2 carbon footprint. These tariffs carry a premium and these are sent to the Carbon Neutral Company to support companies that offset emissions. The premium is actual just a few % higher than standard tariff (although some other energy companies offer a green tariff and the same price as standard).

How to save more with EDF Energy

Like most of the electricity and dual fuel suppliers the easiest way to save money is to pay via direct debit and with EDF you receive an additional 6% discountif you pay by monthly direct debit. Sometimes it’s also cheaper to buy a dual fuel tariff but this is not always the case. So when you are looking at switching your supplier it’s best to get quotes separately for electricity and gas and then get a quote for both and see what the overall costs and savings are.
