Thanks Level Attitude, all my revalidations/renewals in the past 5 years or so have been done here in Ireland, with IAA examiners. Unfortunately, the CAA doesn't allow them to sign off level 6 LP.
As you mention, it looks like a trip up north or across the water will be required. However, I will try ring around different clubs and schools here in Ireland, to see if there are any CAA registered examiners. Or hopefully one might spot this thread....... Thanks for the tip
