Anyone used MSEs Cheap Energy Club?

Our fixed tariff is about to end. I have looked at the CEC and they say I can save £150/year. However when I do the maths the saving is more like £30 pa. I think it’s because they assume we’d stay on the poor value deal with our provider, whereas I’d go onto current providers better deal and save about £120. I’m wondering why they didn’t flag up our existing provider’s better deal.
Anyone else used the CEC and how did it go?

I have for years, they’ve saved me a fortune. It’s really easy to swap too. I do prefer to go to the bigger companies but have gone to others if they have a good deal and have lots of good reviews.

I also have an spreadsheet to calculate costs based on my usage, in my old house i looked for as cheap as possible for gas as I used a lot of it compared to electricity.

I think there might be rules that the comparison has to be against the standard variable rate, even if it makes no sense if you'd not stay on that rate.

Thanks @BarbaraofSeville

I use it for my energy but stay with British Gas everytime but continue to earn the £25/£30 each time for swapping even though I don't!
