You said that you had been installing boilers for years and then went on a Potterton basic combi course. So clearly you had considerable experience before you started going on manufacturers courses.
What I was trying to do was to warn new people that they need to learn the basics of boilers first otherwise they will not get the most out of the manufacturers courses. They are designed for people wanting to learn the specifics on their models.
I have not met anyone who has been on the Bedford course but I would expect that its probably not bad for someone with limited experience. There was a combi course at a local college near Manchester which was said to be very good.
