Thanks to all at B&W for the fantastic help and support.
I recently attended a tribunal on behalf of my partner and had the decision overturned in our favour - from only having standard mobility, to Enhanced on both counts!
A very nervous build up of over a years wait - the actual day was no where as bad as I had feared, just be prepared for A LOT of questions regarding specifics on "how often" etc.
Could absolutely not have managed without your help so thank you to all.
