Welcome to the wonderful world of cleaning windows, the first thing you need to be aware of is what you put into your business is what you will get out of it.
You are in a fantanstic position at the moment because you have not started yet, you have not made any costly mistakes like the rest of us, and the advise that you are receiving, is already saving you time and money.
You say that you are on the dole, so my first port of call would be the job centre to find out what they can do for you, the goverment are always on abouting helping people get people back to work.
You will be able to claim "Tax Credits - Council Tax Benefit and housing benefit if you rent".
You could try the Arrow Fund who will loan you finance to start up with, or you might be acceptable on the Prince Trust or some other enterprise scheme.
You say you want to be a window cleaner, now you have to decide what type of cleaner you will be?
I would recommend that you start out as a "Water fed Poler", it is the way forward in this industry and it is not that expensive to start out with.
Because you are in Wolverhampton ( soft water area) a basic wfp set up will cost you less that £500.
The next very important thing for you to do is charge the right amount for the job, it can be very scary when you first start out and you NEED that business, that you underprice your work, my advise is DON'T underprice anything, you will not go hungry, you will survive.
I live in Birmingham but I have clients all over the West Midlands, if you want to call me then please feel free to do so and I will help as much as possible.
