Absolutely none! Northern Ireland is part of the United Kingdom along with Scotland, England and Wales and therefore travel between Northern Ireland and England requires no passport, driving license etc. Of course it's always better to carry ID of some description but legally as long as you have your ferry ticket, you're good to go.
Actually the republic of Ireland is a republic, which means that England, Scotland and wales have absolutely nothing to do with the republic and hasn't been 1921. Also i wouldn't recommend trying to board a ferry without id as the rules changed this year and you need a passport to fly so i assume ferries are the same as it is a totally differant country, it even has a sea(Irish sea) between itself and Britain. Can i suggest to those who think Ireland is part of Britain, to pack you bags, move back to Britain and get an education, but make sure to have geography as part of there ciriculum!
Passport
None, you just go over the border.
technically none but if travelling by air the airlines demand a passport
A photo identification is necessary to fly from England to Northern Ireland. The airlines prefer a driver's license or passport identification picture. The passport is not necessary if the person flying is a citizen of either country.
Yes. Every person travelling requires photographic identification - passport required for non-EU/non-British/non-Irish persons....photo ID only necessary for EU/British/Irish residents.
I am a british citizen living in northern Ireland and I am attending a wedding in Scotland. I intend to travel to Scotland to the wedding by ferry but intend to fly back to belfast. I do not have a passport but do have a Northern Ireland electoral I.D. card - will this suffice as a means of I.D. at the airport.
NoYou will need a passport or identification depending on your citizenship.
That would depend on where in the world you are measuring or travelling from, and if you are travelling, it would depend on what way you were travelling.
Yeah you should have an id with you, it is very rarely chance that if someone ask you for your id... better to have
That depends on the actual route. Dublin to Liverpool is about 7 hours. Many of the ferries from Ireland actually go to Wales, as it is closer. So Dublin to Holyhead is less than 3 hours. Rosslare to Fishguard is another short journey. Once you get to Wales you would make your way to England by land. Most people travelling directly to England from Ireland will fly.
Different airlines have different rules so it is best to check directy with the airline that you intend to fly with.
No. Ireland is west of England.
