May I ask what pip want to know when they say
report change can you keep your award 

if nothings changed I still use aid an points stay same standard living 

but I walk 20 -50 metres unaided know but.  Before was most days using aid to walk  20-50 metres

When they say  walk 20-50 metres

do they mean. You can only walk 20-50 metres during the day  or can you walk on good day hundred or more metres but can’t walk 20-50 agin or repeadetly 

Can some one explain 20-50 metres aided an unaided examples thanks
