Hi Fleur33
I've included information about safety and reliability in one of your other posts. We can never say whether something is 'enough' for mobility because the DWP is not interested in the condition per se but how it affects you against the specific PIP criteria. If you can show them the evidence that you are unsafe or not able to move around reliably, then you should be able to get an award.
