Go for it as soon as possible!
If you have money, consider investing it in a company called Doorknockers who will build you a round in the area of your choice and for your price.
Price as high as possible in the most affluent areas. Do a search on here for pricing ideas.
Don`t need to have your address on ads. When a customer is confirmed, you can give them your address for cheque payment purposes.
MAJOR rule is: DO NOT UNDERPRICE ON YOUR FIRST JOBS.
Work on a minimum of approx £10 per semi-detached with no extensions or conservatories.(price extra for these)
If you knock 100 houses at that price and 50 say yes...that is great.
DO NOT think that 100 at £6 is better. In the short term, yes it may appear to be better income, but you will regret the lower priced work in the future and dump it. Stick to your pricing and you will have a round that pays well and you enjoy doing. £20-£30 an hour is a guide bracket for you. It may be even more because of where you live but someone local to you may offer advice on pricing in your area.
I would suggest investing in a van based WFP system. Forget trolleys and DIY...more hassle than they are worth in my opinion.
Go on a course.
Search ALL posts on here about starting up/pricing/WFP and trad/payment methods/advertising.
It is a goldmine of information.
It is also a wonderful thing to do with your working hours...Window cleaning! Best move I made.
