Hey Mr RJC,
I have copied below what I posted on another thread some time ago, which I believe is still true.
CPL(H) only £40k approx high risk, no chance of employent
CPL(H) + FI rating £60k approx, low risk much better chance of employment but rewards can be low until you become high time
CPL(H) + IR £70k high risk, potentially high returns is you get to the north sea, have been recruiting recently but by the time you get there who knows.
thats it really
regards
CF
