Sadly, having CAA consent that this is outside of the operators control is not necessarily the 'golden ticket' that it might have once been - as the recent 261 case involving a lightning strike has shown. Even though lightning is on the CAA's list of exceptional circumstances the appeal judge found in favour of the plaintiff.
I agree with ExXB - there is insufficient information provided by the OP to form an opinion other than to say that it sounds as if you were downroute?
As you say you are in Leeds however, I doubt you'll have to look far for the help you seek.
