If you are moving to Ireland from the UK, the good news comes first: you do not need a visa, a permit or a residence card. The bad news is that the UK and Ireland look similar enough to lull you into assuming everything is the same. It is not. Tenancy rules, licences, tax and even the language on the road signs differ, and a few of the differences cost money if you find out late.
Why can British citizens live in Ireland without a visa?
Because of the Common Travel Area (CTA), an arrangement between Ireland and the United Kingdom that predates both countries' EU membership and survived Brexit. In practice it lets British citizens:
- live and work in Ireland;
- study there;
- use public healthcare on the same basis as Irish residents;
- vote in local and general elections.
No application and no permit is needed. You still need an address and a PPS number to function, as explained in the PPS number guide. The CTA settles your right to live in Ireland; it does not settle your taxes. Tax residence follows its own test, set by Revenue.
What changed for British citizens in Ireland after Brexit?
Less than people feared, and mostly for family members. Since Brexit, British citizens are no longer covered by EU law, so the EU residence rules in living in Ireland as an EU citizen do not apply to you. The CTA replaces them.
Where Brexit bites is for your non-British, non-EU relatives. Their rights follow other rules, and you should check with the Immigration Service Delivery before they travel.
Three other practical changes:
- A UK driving licence is valid for a visit but not for living in Ireland.
- A car coming from Great Britain involves a customs declaration and VAT, sometimes duty.
- A UK company director no longer counts as resident in the European Economic Area, which matters if you start a limited company.
How do you exchange your UK driving licence?
Once you live in Ireland you must exchange your British licence for an Irish one. The exchange costs €65 (free from age 70) and is done through the National Driver Licence Service (NDLS). You need your original licence, your Public Services Card and a verified MyGovID, plus an eyesight report because the UK is a "recognised state" rather than an EU one. A learner permit cannot be exchanged, only a full licence.
Insurance is a separate step: ask your British insurer for the no-claims history it must give you before you leave.
What happens to your UK pension and National Insurance?
An agreement between the two countries lets your British contributions count when you claim Irish benefits, and pensions already being paid continue. If you receive a UK state pension and live in Ireland, you can apply for a medical card with an S1 form from the UK, and cards obtained before Brexit remain valid.
For tax, the Ireland-UK double taxation convention decides which country taxes what. If you keep income from Scotland, remember that Scottish income tax has its own rates; the convention still works at UK level.
Mixed incomes (UK rent, UK pension, an Irish salary) are where a move from the UK gets complicated. Moovy can lay out which country is likely to tax what, and flag where a tax adviser is worth paying for.
What is different about renting and buying?
Everything. Do not carry assumptions across the Irish Sea:
- Deposits: at most one month's deposit and one month's rent in advance in Ireland. There is no deposit protection scheme like the UK's; the RTB handles disputes.
- Leases: since 1 March 2026 new leases follow a six-year cycle with capped rent increases. See tenant rights in Ireland.
- Buying: a booking deposit is refundable and nothing binds you until you sign the sale contract (except at auction). Your solicitor, not the agent, protects your interest. See buying a house in Ireland.
How does moving to Ireland from the UK differ for tax and work?
On work, nothing stands in your way. The Common Travel Area lets you take a job, start a business or study without a permit. On tax, the first question is residence: you are tax resident in Ireland if you spend 183 days or more in a calendar year, or 280 days over two years. The year you arrive, split-year treatment can limit Irish tax to your salary from the date you landed. Your remaining UK income is dealt with under the Ireland-UK double taxation convention, which says which country can tax what.
Employees do not have to file anything at first: your employer deducts income tax, USC and PRSI. What you must do is register the job on myAccount so that you are not put on emergency tax. If you have a UK pension, rental income or a business, you will probably file a return, so check Revenue's guidance or ask a tax adviser.
What about healthcare when moving to Ireland from the UK?
Once you are resident, you have access to public healthcare in Ireland on the same basis as Irish residents. That means paying to see a GP unless you hold a medical card or GP visit card, with public hospital inpatient charges abolished since April 2023. The Drugs Payment Scheme caps household medicine costs at €80 a month. In the first weeks, while you wait to be recognised as ordinarily resident, a GHIC or a UK driving licence or two proofs of UK address are enough for necessary care as a visitor. Read healthcare in Ireland for expats for the whole picture.
What documents should a UK citizen bring?
- A valid passport, or your birth certificate (showing your mother's maiden name) with a full valid driving licence, for the PPS number application.
- Proof of an Irish address, in your name, less than three months old.
- Your UK driving licence (to exchange) and, if you bring a car, the V5C registration document.
- A claims history statement from your UK car insurer, which you can request before you leave.
- Pension and National Insurance records if you are close to retirement.
Keep your UK bank account while you open an Irish one: the UK is in the SEPA zone, so euro transfers work, but payments in sterling can carry exchange fees. Our guide to bank account in Ireland explains how to bridge the first weeks.
What is the best way of moving to Ireland from the UK in practice?
Do not move your life in one weekend. Visit, rent short-term in the area you prefer, then settle into the paperwork in the order set out in moving to Ireland: the step-by-step guide. The key difference from a move within the UK is that you now sit in a different tax system, a different housing law and a different health system, even though the language is the same.
What habits trip up newcomers from the UK?
- The currency is the euro in the Republic, the pound in Northern Ireland.
- Distances and speed limits are in kilometres in the Republic, miles in Northern Ireland.
- Emergency number: 112 or 999 in the Republic, 999 in Northern Ireland.
- School calendars, qualifications and curriculum differ; NARIC Ireland can compare your diplomas.
- Sterling payments from a UK account can carry exchange fees; see bank account in Ireland.
What should your first month look like?
Find an address, apply for your PPS number, register your job on myAccount, exchange your licence and book your car registration if you bring one. Most of these steps are identical for any newcomer; the CTA mainly saves you the visa stage. For the full sequence, read moving to Ireland: the step-by-step guide.
