Look After My Bills

..just wondering if anyone has any experience of the validity of their savings claims. This is my experience, earlier today:

I am with Powershop on their Baseline 2018 version 1 tariff which I entered.

The comparison said it'd save me £427 a year by switching to Igloo. On checking the tariff the Igloo rates quoted were 13.485p per kwh and 24.5p per day for electric and 3.374p per kwh and 24.5p per day for gas.

[/INDENT]On my most recent bill, for December 2018, I paid 10.1549p per kwh incl standing charge for electric and 2.1697 per kwh including standing charge for gas.[/INDENT]
