Yeah, never undercut is a good motto! I always like to find out what other windys charge, so i can charge more, especially for a contract !!
I'd love to know in more detail how some of your logic works, you actually price so your competition keeps the job?
Meanwhile, back on planet earth if i can get a job by charging a tenner less, then i'll probably charge a tenner less. Simple.
Mind you, i'm not debating what to pay my staff or what rate i need to pay two men in a van, i just go do it myself !!!
