I need backdate payment 2017

Hey there @Dhuuh28222 welcome back. 😊

I'm afraid we are not the department for work and pensions, we are a disability charity, so cannot backdate any benefits, you'll need to call the DWP on 0800 169 0310

If you call that number during the week, you'll be able to speak to someone from the DWP who will be able to advise you.
