Hi. I want to change my mum to a new, cheaper tariff with her existing supplier (British Gas). The new tariff is only available on compare sites, but the article I learned about this new tariff from says it is available to existing customers.
My question is, do I do this switch exactly the same as I would if switching her to a new company (though all the questions asked/details needed are obviously worded as if changing suppliers)?
I have just filled out the online form to switch her, but then then started wondering if there might be more to it, something that I have overlooked!
