I would say dont tar people from a council house with the same brush as scum bags, these are in every area, if you choose not to do because you want bigger houses then fair play, I was bought up in a council house and own one now and I always pay my bills on time as do my customers that live in council houses. You will always get knockers but that from experience is in all fields.
You will always get scum everywhere it is not tied to council estates, I will take on work anywhere, as I get on with any class posh or not so posh, as long as im paid I dont mind.
Also you will find that the general people in council houses pay there way more than the people that are in fine country houses. They are more down to earth.. and dont expect things, I do both and in between so saying from what I have faced and know.
