As one of the world’s top tourist destinations, the United Kingdom (UK) has no shortage of interesting things to see and do. England, Scotland, Wales, and Northern Ireland each have distinct histories and cultures, as well as their own major attractions.

See our product selection criteria and guidelines here.

Which power outlets do they use in the UK?

Type G outlets are used throughout England, Scotland, Wales, and Northern Ireland (see the picture). These sockets have three rectangular holes, including a ground. Outlets in the UK often have a small switch right above them that must be turned on in order for electricity to flow. Experts generally agree that Type G is by far the safest of all the kinds of sockets found around the world – a small price to pay for a little extra bulk. Outside of the UK, this outlet type pretty much only exists in former British colonies such as Hong Kong.

Like the majority of countries, the frequency of the UK’s electrical grid is 50Hz. The standard voltage there is 230V, meaning appliances rated between 220 and 240V can be safely used without a voltage converter.

What kind of power adapter do I need for the UK?

If you’re making your first trip to London (or somewhere else in the UK), you’ll probably be asking, “What plug do I need for UK?” The outlets in the UK only work with one plug type, so if you’re from the US, you’ll definitely need an adapter for your trip.

A US to UK power adapter will allow you to use American devices with British sockets. Fortunately, US and UK outlets look nothing alike, so you probably won’t make the mistake of trying to plug in an American device without a power adapter.

This Universal Adapter pictured is the one we recommend because it will charge your personal electronics in the UK and in over 100 other countries around the world. It also comes with a built-in fuse to save your devices from power surges.

What’s the electricity and power supply like in the UK

As one of the world’s wealthiest countries, the UK’s electrical infrastructure is among the best, and there aren’t any noticeable differences among England, Scotland, Wales, and Northern Ireland. Due to the strict regulations in place, electrical fires, surges, and shocks are uncommon.

Outside of severe storms, power outages are rare throughout the country, including in rural areas. However, depending on the deal that’s ultimately reached, Brexit may bring increased blackouts to the UK in the near future, especially in Northern Ireland.

Do I need a voltage converter for UK?

You’ll need a US to UK voltage converter if you want to use devices that are rated below 220V; the other common range is 110V to 120V. In the US, devices in this range normally include irons, electric razors, hair dryers, and curling irons. Plugging these devices into a UK outlet without a transformer will most likely destroy them and may shock you or start a fire. If you aren’t sure whether a particular device needs a converter, check the tiny print on the plug.

Another option is to buy dual-voltage devices, which have a button to switch between 110/120V and 220/240V. You can also order travel-sized versions of these devices that are rated at 220/240V or purchase new ones in the UK.

Other UK Packing List Items

In addition to your US to UK power adapter, these items will help you pack with intention and expand the possibilities of your getaway. Also, check out our UK packing list for more inspiration and ideas.

  • 1. Neck Wallet / Passport Pouch

    All major cities (such as London) in the UK have serious issues with pick-pocketing. Instead of putting valuables in your pocket or carrying a handbag, store your cash, credit cards, and even phone in a neck wallet. A thief could easily reach into your pocket or bag, but they probably won’t be able to grab something that’s underneath your clothes and securely around your neck.

  • 2. Lipstick-Sized Portable Charger

    If you’re using your phone as a camera or for maps while on your trip, you’ll definitely want to make sure it stays charged. Fortunately, all you need is a tiny portable charger, and you’ll be able to recharge it throughout the day, no outlet required. Seriously, this little device has saved us countless times!

  • 3. Packing Cubes

    Staying organized on the road is a must and packing cubes are a lifesaver. Instead of tossing everything in your suitcase or backpack individually, pack your clothes and other items into cubes. Use one for shirts, one for dresses, and so forth, and then put them in your main bag. It’ll be much easier to find what you need, and your bag won’t explode when you open it. These ones even have a little index card holder on the back so you can write exactly what’s in each cube – total GAME CHANGER!

  • 4. Windproof Travel Umbrella

    The UK is notorious for it’s rainy and windy weather and that’s why we highly recommend you bring a windproof travel umbrella like the one pictured. This item will help keep you dry even on the worst days you can still be out enjoying the famous sites and city delights. One feature that makes this one extra valuable is the waterproof case it comes with so that you can zip up the umbrella and put it in your backpack even if it’s drenched!

  • 5. Extra Phone Charging Cables

    Charging cables are easy to forget, but they’re critical for a smooth trip. Whether you want to charge your phone with a traditional charger, a portable one, or the USB port on a plane or train, you’ll need to be able to plug it in. To be safe, bring an extra cord; it’ll be a real pain if the only one gets lost.

    If you’re really prone to it, avoiding jet lag can feel like a reason to avoid trans-oceanic flights, especially if the trip would be a short one. Instead of skipping your trip, bring some jet lag relief pills to help you adjust to the time difference quickly.

    Good VPNs like NordVPN aren’t only for tricking your Netflix account into giving you access while you’re out of the country. They’re also a security measure, protecting your data and private information from potential thieves. Taking extra precautions is especially important when you’re traveling and frequently using Wi-Fi connections in cafes, airports, and other public places.

  • 8. Travel Insurance for the UK

If you fall sick or get into an accident and need to go to the doctor in the UK, you want to know that your medical expenses will be covered. Plus, travel insurance covers theft, trip interruption, and other emergencies. We believe it’s an absolute must for any international travel.

Beyond these major metropolises, there’s also the Canterbury Cathedral, the Roman baths in Bath, the White Cliffs of Dover, the ten-mile-long Lake Windermere, and, of course, the mysterious Stonehenge. Or, plan your visit around seeing the country’s many, many castles; some of the most impressive include Alnwick Castle, Edinburgh Castle, Carlisle Castle, Durham Castle, and Leeds Castle. There’s also fantastic hiking throughout the country; if you’re up for the challenge, tackle the 96-mile West Highland Way, an iconic thru-hike in Scotland.

  • 5. How’s the best way to get around in the UK?

    Many of the UK’s other metropolitan areas also have well-developed public transportation systems, and Uber is also available in most towns as well.

    For intra-city travel, Britain is well-connected by train, and Northern Ireland has its own rail system. Numerous different train companies operate throughout Britain, but information for all of them is available at National Rail. Long-distance buses connect the country as well, offering a cheaper (but slower) option than the train. A road trip is also a great way to explore, and renting a car in the UK is fairly easy, although it can be costly. If you’re really in a hurry, cheap flights connect the country’s major cities.
