In reply to elliot.baker:
> Is that a trad grade?
Yup.
And just to make this bit extra clear: "British tech grades" -- the number-and-letter after an adjectival grade -- are not the same as French/sport grades, and they don't match up, despite looking the same.
> But if there is one that says f6a, is that the same as when an indoor wall says '6a'? Is that a sport grade or is it not that simple?
It could be a sport grade, but confusingly it could also be a bouldering grade -- the "f" can stand for "Font" as well as "French".
Sometimes, it's clarified by putting the bouldering grade in all capitals -- "6A" rather than "6a", but not always.
In the case of Shining Cliff, it looks like these are describing boulder problems (there aren't bolted sport climbs on gritstone anyway).
The Rockfax conversion table seems decent:
