My passport expired a couple of years ago.
I have been asked to go to Ireland for a couple of days, for work ( flying Manchester to Cork ) in Mid January.
I’m concerned that I might not get a renewed passport back in time, but believe that as a UK national, I don’t need a passport for this trip. Maybe using my photo card driving licence as I.D.
Anyone done this, or do it regularly ?

just send off for a new passport

a friend sent his off last week, got it back in 3 days

Wow ! That was quick !

Photo ID is enough. A driving licence will do. See linky.

legally just photo id, but ryanair will only accept valid passport last time i checked, ferry is just photo id,

I do it once a week on aer lingus with my drivers

Thanks guys !
Should know which airline we are on tomorrow, will probably check with them, but will crack on and get renewal applied for anyway.
