In my ignorance I have no idea what that qualification is - would my 9 'O' Levels from 1960 be okay?
You are missing the point in what you have said, though I expect you suspect it by asking the question.
The entire purpose of qualification levels is to exclude old people without falling foul of the age discrimination laws.
You have Level 2 qualifications.
Whatever your qualification level, you will always be one level short of what you used to need for any particular job.
Anyone qualifying since 2000 has had their modern qualification upgraded a level, even though theirs is in reality a lot easier to get.
The same trick at degree level is achieved by bumping up the required grade. If by some chance you were one of the 5% to get a First in your generation, as opposed to the 50% who get it out of the cornflakes packet now, there will be another clause which catches you out.
And to answer the question about "Okay?", No.
You will know more than your boss. And by being old you will be better trained, more experienced, and have some backbone too. They hate that, all of that. Which is why old people must be excluded.
Your job description will require you to point out safety failings, inefficiencies, and corruption. The very last thing they actually want is for you to do this, partly because your boss will be responsible for all the aforementioned faults, partly because s/he can't fix them, but mostly because if by some miracle anyone higher up listened, you would have to get your boss's job.
Of course, if you don't point them out, you will be blamed when the consequences of such happen, because it's your responsibility to do so - although of course you never get the authority to effect your responsibilities.
