UK vs EU Plugs: What Adapters You Actually Need in Ireland

This is the thing that caught me out the moment I arrived. I had a suitcase full of chargers and not one of them fit the wall. If you're moving to Ireland from mainland Europe or the Americas, your plugs won't work here — and there's an important detail beyond just the shape that can cost you an appliance if you get it wrong.

Ireland uses UK plugs, not EU plugs

Ireland uses the Type G plug — the chunky three-pin rectangular one, the same as the United Kingdom. It is the only socket type you'll find in Irish homes. EU two-pin plugs (Type C, E, F) physically do not fit, and neither do US flat-pin plugs.

So if you're coming from:

  • Mainland Europe — your plugs won't fit. You need a Type G adapter.
  • US / Canada / Brazil and similar — your plugs won't fit either, and you may need more than an adapter (see the voltage warning below).
  • UK or Northern Ireland — you're fine, same plug, no adapter needed.

The part that actually matters: adapter vs voltage converter

This is where people destroy a hairdryer on their first morning. An adapter only changes the shape so the plug fits the socket. It does not change the voltage.

Ireland runs on 230V. This is roughly double the 120V used in the US, Canada and parts of South America. The voltage is the same as the rest of the EU and the UK, so European devices are fine with just an adapter.

Here's the simple rule before you plug anything in:

  • Look at the small print on your device's charger or label.
  • If it says "100–240V" (or "50/60Hz"), it's dual-voltage — an adapter is all you need. This covers almost all phones, laptops and camera chargers.
  • If it says "120V" only, plugging it into 230V will damage or destroy it, even with an adapter. You need a voltage converter, or better, replace the device with a local one.

The usual culprits for single-voltage are hairdryers, straighteners and some older small appliances. For those, it's often cheaper and safer to just buy a cheap local version than to carry a bulky converter.

What I'd actually buy

For most people moving to Ireland, two small purchases cover you:

  • A UK (Type G) plug adapter — ideally one with built-in USB ports so you can charge your phone and laptop from a single socket while you settle in.
  • A UK extension lead — Irish rentals often have surprisingly few sockets, and one extension lead with several outlets means one adapter can power your whole desk or bedside setup.

RoomNabs Tip: Buy the adapter before you fly, or pick one up at the airport. Your first evening is a lot easier when your phone can actually charge. You can always buy a better multi-socket setup once you're settled.

I didn't buy an adapter before flying, which was a mistake — my first night I couldn't charge anything. The next day I grabbed a UK adapter at a local supermarket for about €4–5. Cheap and easy, but I wish I'd had one in my bag when I landed.

Quick FAQ

Do EU plugs work in Ireland? No. EU round two-pin plugs don't fit Irish Type G sockets. You need an adapter, but no voltage converter — the voltage is the same 230V.

Do UK plugs work in Ireland? Yes, identical. UK devices need nothing extra.

Will my US devices work? The plug won't fit, so you need an adapter — and you must check the voltage label, because many US appliances are 120V only and will be damaged at Ireland's 230V.

Bottom line

Sort your plugs before anything else. Get a Type G adapter and an extension lead, and check the voltage label on anything with a motor or heating element before you plug it in. Do that, and you avoid both a dead phone on night one and a fried hairdryer on morning one.
