OK back to the original question.
If the licence was introduced into England, Wales and Northern Ireland and it was enforced with all the powers that the councils have and can apply, these are some of the ideas they might use.
1 They can break their areas into different zones, and you will end up paying to work in each zones, instead of just 1 council area (this is already happening).
2 They can dictate what vechicle you should use, so for you who use a car to carry your ladders, you might have to buy a van.
3 They can dictate that your vechicle undergoes a separate vechicle road safety test (this will affect those who use wfp)
4 You will have a search carried out on your past, and if it is not squeaky clean, you could find yourself out of business.
5 They could have different fees for the type of work you do (domestic or commercial being charged differently)
6 They could insist that you have a yearly medical, which you will have to pay for.
7 They could insist that all your equipment is inspected and tested every year (you will have to pay for this)
8 If you have not upto date on your Council Tax Bill, they could revke your licence (this is also being carried out)
9 If you are a council tenant and you are behind on your rent, they could revoke your licence.
10 If you owe a council parking fine, your licence could be revoked.
11 They could insist that you are trained in the safe way of using ladders or wfp (you will have t pay for this)
The list goes on and on, on what they could do, and they might not do all of the above, but I bet they will do some of them.
If you want a licence and you want that licence to work, then it is going to cost you, and the fees that are being charged at the moment are not enough to cover that cost, so the fees will have to be increased.
Vote YES at your own PERIL, because as soon as the licence happens, there is no going back.
