I would confirm what the others have said: a 3-yr licence does NOT qualify you for a Blue Badge.
Your local authority will have set some limits on how far you can walk unaided (or unsupported), and in the absence of higher rate DLA mobility (or similar) that is what will be used.
Often this is 20 metres - or even less.
Now, two things:
1 - Do not send back your old licence. Wait until you have the new one. They say something like “this letter can be used as a licence until you have your new one”. I wonder how many policemen know that. How many car hire firms know that. I would not like to try it on a Gendame somewhere in France. I have never returned my licence when asked - and never been asked again.
2 - The present BB setup is that you can fill in a form on the YouGov website You can get to the application system direct at:
or download a form for a look (this one is from Bromley, Kent [well it was when I lived in Kent] and they are all the same.
Watch the questions. I suggest copying or multiple downloads, and filling one in in pencil first. You will be asked how far you can walk (no problem for me, i cannot manage two steps without support) and much later on where is the nearest local landmark (could be a street corner) that you can walk to. The two answers had better be the same distance!
If you can do 50 metres without support - forget a BB. 20 metres with two sticks and a rest part way - probably. they are getting harder to get (and with good reason). The do not seem to consider that some folk need a BB for the wider parking space because they need that just as much to be able to get in/out.
Do it online, and the form gets sent to your local council by the firm that produce the BBs. The council decide and tell the firm when they get your £10 fee, and the firm create, and mail out your badge. I have covered my bets by contacting my local BB unit and asking when they will make the decision.
Remember you will need a digital photo (to passport standard), a copy of your Passport or Driving licence (to prove you are who you claim to be) and a copy of a utility or Council Tax bill to prove that you live in that council’s area.
Jump through enough hoops, and get a BB. Now you have to remember to display it.
