The term "Smart Switching", it is not only an incorrect description of what this section tries to convey but it is also displeasing in my opinion.
I actually thought it had to do with bank account switching or utilities and telecom account switching.
I would like to suggest that you seriously thing about changing this term.
"Smart Switching" in the context of the specific screen can mean switching/ rebalancing budgets between the different categories.
I thought it was about switching bank accounts, originally, which is something that giffgaff do not provide for in their compariosn site.
I think the term "Smart Switching" may have been copied from marketing material of other comparison sites/ platforms (I actually have one on my mind) and "Switch to Save" maybe more appropriate.
