Disabled facilities grant
I think it may have been a reminder of the Disabled Facilities Grant

My own daughters cared for was helped through a grant after their return from hospital after Covid three Christmas’s ago. It did take a while to sort out, and in their case it wasn’t for them to get to a bedroom as my daughter managed to ‘swap’ a downstairs craft room with their bedroom and they managed with a commode for the first few months, but with the main bathroom/walk in shower being upstairs an assessment was finally made and the stairlift fitted.
It is means tested however so in the case of my sister in law she found it better to pay privately for a walk in shower and stairlift rather than leaving the debt against the house for her children to sort out when she passed away a couple of years later.
