My husband was awarded lower rate care and low rate mobility dla last August 2012. This was 2 years after he applied (had to appeal as got turned down first of all) , so this award was based on how he was August 2010.
He seems to have got worse since then, particularly with regards to how far he can walk.
I see on the DLA gov site that if you have a change of circumstance including if your condition has got worse, you can just phone up the help line.
Wondering if anyone has done this and what the process is i.e. is there more form filling, medicals etc.
