A rating tells you how they behave — not what they’d charge you
Service scores are national. Prices are not: So Energy’s unit rates and standing charges vary by distribution region and by how much you use. Enter your postcode to see what So Energy would actually cost at your address, next to the rest of the market.

So Energy’s official customer service rating
At 2.86 out of 5, So Energy sits worse than the 3.26 industry median for the quarter, placing it 12th of the 16 suppliers Citizens Advice ranks.
We use the Citizens Advice rating rather than a score of our own because it is independent, published quarterly, and covers every supplier with more than 25,000 customers on the same measures. It combines complaint volumes, contact wait times, billing and metering accuracy, and customer commitments.
Citizens Advice revised its methodology on 24 March 2026, so scores from January to March 2026 onwards are not directly comparable with earlier quarters.
What we can and can’t tell you
We do not collect our own customer reviews of energy suppliers, and we do not publish a star rating of our own. The only score on this page is the Citizens Advice figure above, attributed and dated.
What we do hold is pricing. So Energy currently has 11,383 tariff combinations in our live comparison feed, which is what the postcode check above prices for your address and usage.
A good service score and a good price are different questions. A supplier can rank well on complaints and still be expensive for your usage, or rank poorly and be the cheapest deal available to you. Check both before you switch.
Frequently asked questions
Is So Energy any good?
On the official Citizens Advice star rating for January to March 2026, So Energy scores 2.86 out of 5 — below the industry median, ranked 12 of 16. That measures service, not price, so run your postcode to see what it would charge you.
What does the Citizens Advice rating measure?
Complaint volumes, how long customers wait to make contact, billing and metering accuracy, and customer commitments. It is published quarterly and covers suppliers with more than 25,000 customers.
Is So Energy cheap?
That depends entirely on your region and usage — the same tariff is priced differently across distribution areas. We hold 11,383 So Energy tariff combinations and price them against the £1,663 Ofgem cap on your own consumption.
Does a low service score mean I should avoid them?
Not on its own. Your gas and electricity supply is identical whoever bills you — the score reflects how easy the company is to deal with when something goes wrong. Weigh it against the price difference for your home.
