What is a Discretionary Housing Payment?
A DHP is an extra payment to help people who claim housing benefit and are struggling to pay the rent.
Your council may award you a DHP if for example you're affected by the bedroom tax or benefit cap. You could also get a DHP to help pay a tenancy deposit, but only if you are already getting housing benefit where you live now.
You can also apply for a DHP if you getting universal credit to help pay your rent.
