Interesting that the DWP has just revealed in correspondence that it appears to have a policy not to stop ESA claimants' payments if they're known to have mental health problems and are unable to complete and return a questionnaire,
"...in accordance with DWP policy, if someone with a mental health condition does not return their ESA50 questionnaire within the usual four week period their benefit does not end, as it would for other claims".
This comes hot on the heals of it being revealed that the DWP also does not stop payments when claimants' with cervical myelopathy cannot return questionnaires.
Will be interesting to see if any cases come through that have "slipped through the net"!
