Igloo to Eon Next

[mrst3]

Anyone been switched from Igloo to E on Next
I'm astounded by my December to Jan bill!!!??
Seems to be double what we've had in past 😢😢😢

What are your unit costs with both suppliers?

New supplier Elec unit 22 standing charge 23.50
Gas 4.07 standing charge 26.12

Old elec 19.741 standing charge 23
Gas 3.794 standing charge 26

But they're telling me my bill for Dec to Jan is 481.55 😳 yet when I click on actual breakdown it's showing that's for Nov to Jan if it's latter then I can live with that but not for one month
