Healthy start vouchers = change of address?

Dontknowanymore

Hi
I have moved into a womens refuge for a max of 6 months, I tried to phone the healthystart vouchers helpline and before I even got through to a person it said something along the lines of ''this line os not for updating change of address''
So how do I change my address with them?
Is it automatically done via tax credits of do I fill in another form?

It's done automatically when you change your address by tax credits so you don't need to call them.
