I applied for my replacement Blue Badge a few weeks ago, this was the first time using the new "completely online" service which meant I didn't have to send anything in the post or get photographs / documents 'certified' or anything.
I was a bit wary as to whether my application would be successful this time (even though it has been the last two times since I started using a badge). Because, whoever had programmed the online application form had decided that 100 characters was
more than enough to enter one's answers to many of the questions. (Pro tip: when you're trying to explain how a disability affects you, you need a tad more space than that). Also there wasn't an 'any further comments' box at the end which would have been nice because there were things I wanted to say, which I had stated in my prior applications, that there just wasn't the opportunity to say this time.
So as I said, I was feeling a bit glum about it because I was fretting that I hadn't been able to fully get my point across. But, checking emails reveals that my application has been successful

So we just have to pay them the princely sum of £20 and hopefully soon, post deliveries permitting, the badge will be in my possession ready for when the current one runs out.
It would be nice if I didn't have to keep doing this every 3 years (my disability isn't going to go away or get better!) but I can't complain really.
