It was already fairly clear by then that major employers require a 2:1.
That's what you put on job application forms. We don't use a GPA.
A 1st is good. A 2:1 is fine. A 2:2 is a problem. A 3rd is a failure.
Some people use cockney rhyming slang - a 2:2 is a 'Desmond' (Desmond Tutu, two-two).
In some cases you can get a double 1st, or triple 1st, but these are very specific to your university and are about what courses you took.
