Cost of living payment

Hello all,
Please the cost-of-living payment is available for anyone in receipt of DLA(child)
I have a client who is on PIP and had her payment but her daughter who is on DLA had not receives any payment yet.
She is wondering if its per household but i said i believe it’s per person not household.
Thought i drop a text in case i have missed something.

You can report the missing payment here

You will only get one £150 payment even if you get more than one disability benefit. If your child gets a disability benefit, they will get a separate £150, if eligible.
