Asda payroll office address? help

SandA

Hi

I'm an asda employee on maternity leave, currently filling out tax credits forms.

I need asda's payroll office address + telephone number. Now i'm confused since asda's payroll is done through ceridian, so i dont know if its asda's head office address or ceridians? Ive tried searching for it online, but can't find anything. On my P45 it has their head office address, but on the tax credits form it says 'payroll office address' so i'm not sure if i put the head office address? On the notes it says to check P45 and this is the only address on there, but no telephone number.

If i can't find, i will ring up my asda and ask, although thought i'd try here first as i'm sure i wont be the first to be confused!

thanks
