Local councils don’t go to great lengths to make Blue Badge assessments. They will not generally contact health professionals other than your GP who needs to support your application.
If you do not get DLA they need to make a determination based on the info that you give them.
I snagged this from London Borough of Richmond to give an idea what they are looking for
Unable to walk:
• You need to show that because of your disability you cannot put one foot in front of the other.
• If your only way of getting about is to “swing through” crutches then you will be considered unable to walk.
Virtually unable to walk:
Unable to walk very far without experiencing severe discomfort; discomfort can mean either pain or breathlessness; extreme fatigue and stress may also be taken into account (It has been accepted that discomfort is subjective and that some people have higher pain thresholds than others).
Unless both your legs are missing then you will need to show that you experience severe discomfort even when using your artificial aid.
In assessing the above the following factors will be taken into account:
• Distance you can walk, without experiencing severe discomfort.
• Speed at which you walk.
• Length of time you can walk.
• Manner in which you walk.
The question is about walking out of doors not in your home.
Exertion required to walk:
This is to establish if walking would constitute a danger to your life or whether it would be likely to lead to a serious deterioration in your health.
• The criteria is intended for people with serious chest, lung or heart conditions.
• Some people with haemophilia may also qualify.
• Serious deterioration does not need to be permanent but it should require medical intervention for you to recover.
• People with epilepsy will need to show that any fits were brought about by the effort required to walk.
As with DWP applications you need to cross Ts and dot Is. It will not be a healthcare professional looking at your application. Make it easy for them to match what you have said with their check list.
You must appeal if you think they have got it wrong. In your letter point out why they are wrong and restate your case as succinctly as you can. I know that some people favour long wordy explanations but I think in this case less might be more.
Good Luck
