But then again, you will have the customers which are trying to be smart and asking you to get the material list to them so they can get stuff themselves which I think it’s a no go though. I’d rather take care of getting my materials. It is not about the mark up but it’s to make sure I have the right products on site and not having to drive around. For some people I have a quote which has about 4/5 different boilers which are more likely the poor low budget boilers which I am not interested in fitting. The reason is I don’t like the fact I install plastic flues and stuff like that. Furthermore they still find somebody who is cheaper in labour as I do not fit a boiler for 600
