Hi John - 20 euros? I think that is ok, my cert in UK cost me 15 pounds, its the conversion in manila that will stiff you at about 80 euros, 60 pounds or 5500 php and it only takes 30 mins to process convert and stamp. That's the British Embassy. I queried it and they stated it was expensive to maintain a consulate in Manila and had to justify the costs. I beg to differ!
I will talk to the Irish Embassy here also, (best make sure I get my irish passport renewed first eh? )
Just for everyone's info, UK and Ireland are not Schengen countries, but they have a common travel area policy for UK and Ireland where any ID would work for travel and not passport only. However there is a recent proposal for air travel etc that this is ended on security purposes. They have yet to discuss how road travel from North to South will be covered, but I suspect it will be unworkable.
