ccn1? help please

[jldplumb]

looking at doing my gas next in the next few weeks. ive been plumbing for 5-6 years and have always worked with gas safe boys but never done my acs, so im looking at a course near me its £950 for 8 days (4 days training) but its ccn1 only not cookers etc. i was just wondering what does the ccn1 cover you for and what cant you do with it?, as it might be a few months before i can afford other modules. Also what modules are must haves?
