Pros and cons of Sainsbury’s Energy

Pros

  • Low carbon electricity. E.ON, which provides Sainsbury’s Energy customers, commits to supplying its household customers with electricity from 100% renewable sources. This can come from E.ON’s own generation facilities or matched through regulator Ofgem’s Renewable Energy Guarantees of Origin (REGO) scheme.
  • No exit fees. Customers on either of Sainsbury Energy’s 1 or 2 year fixed tariffs are not charged any exit fees if they want to leave their deal early.

Cons

Our verdict: Is Sainsbury’s Energy any good?

There are limited online reviews from Sainsbury’s Energy customers, but as the trading name of a larger supplier, it could be worth a look if you’re after a long-standing company. Its parent company E.ON has committed in recent years to providing electricity from 100% renewable sources, but there are other companies currently offering green tariffs that are worth considering, if that’s a key factor in your choice.
