Personally i have always been dubious about franchises. And looking at their set up costs of £16k plus vat, i would be asking what does it get me and for how long. Spend half of that and set yourself up, and use the other half to keep your head above water whilst you get established. They will take your money, no problem, but like Mr Electric they will over charge and you will get sod all work. I also would imagine they will get a bad reputation as all they want is your cash, and they have no interest in your skills etc. Todays binman, tomorrows sparky. That in no way implies that you are unskilled or otherwise, it just points out that they only give a ---- about money.
Cheers.....Howard
