Exactly. You don't actually get any money back but it is offset against your personal taxable allowance when you do your end of year self assesment.Still pretty confused?
I know i can register as self employed online but as for claiming
Im assuming that means spending the money then putting my earnings in deducting the 'claimed' stuff and i then grt taxed on the remainder
So really you dont get the money back it jus means u are taxed less
