Given PIP payments are made in arrears, payment will be taken/redirected to motability on your next payment date and every 4 weeks from then on. What I think, but can’t remember is whether mb will take a 2 week payment and DWP pay 2 weeks in to your bank account, given your are in the middle of your payment date. Hopefully someone will be along shortly and give you a more direct answer. @wmcforum can be quite clever, but don’t tell him I said that 🙂
