Disabled Facilites Grant.
You will have to get hold of your Occupational Therapist.
Either Social Services or your MS nurse ( if you have one ) should point you in the right direction.
They will do a financial accessment on you before they go ahead.
And should access you to see what you need.
It’s not a speedy process but you will get there in the end.
If there is anything else you need let them know at the same time and get it all done.
Get an idea of what you want first because they can tend to say what they think you need but it may not suit you.
