Compare energy suppliers' customer service

Mae’r cyngor hwn yn berthnasol i Cymru

Although price is often most important, it's a good idea to look at how well your energy supplier deals with customer service.

Every 3 months, we compare suppliers across 5 different categories and rank how good their customer service is - we score each supplier out of 5.

If you can't find your supplier in the table, we might not have enough data to give them an overall score. You can find these suppliers at the bottom of the page.

Click on a supplier to find out more about how we worked out their score.
