Many thanks for your reply. My sons award was for 3 years, so will be up for renewal 2022 (I believe the renewal form will arrive a year before). The Asthma does appear cause any additional problems regarding his PIP activities - he was mainly waking at night short of breath - but the inhalers seem to be giving some relief when he takes them. I am in the opinion that the award he was given was fair when he was awarded.
