Info on power adapter plugs for the UK

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.

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 you won’t want to forget!

In addition to your US to UK power adapter these items will help you on your travels:

  1. Neck Wallet / Passport Pouch
  2. neck walletAll 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.

  3. Lipstick-Sized Charger
  4.  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!

  5. Packing Cubes
  6. packing cubesStaying 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!

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!

  9. Extra Phone Charging Cables
  10. 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.

  11. Jet Lag Relief Pills

Other FAQs about traveling in United Kingdom

Spring and fall are generally the best times of year to travel to the UK. Most of the country is relatively dry during these months (although it can rain anytime), and the temperatures are warm but not too hot.

It rains year-round in the UK, though the winter months are the wettest, and Scotland and Wales tend to see more rainfall than the other areas.

3. What are some fun things to do in London?

A city of over eight million people and one of the world’s most beloved travel destinations, London has more than enough attractions to occupy visitors for weeks.

Among the most iconic are, of course, Buckingham Palace and Big Ben, along with the Tower of London, Westminster Abbey, and the London Eye.

For art and history, check out some of the city’s many museums, like the National Gallery, the British Museum, or the Victoria and Albert Museum. Explore the Thames by kayak or cruise, or just stroll along its banks, and take some time to wander through interesting neighborhoods like Camden, Soho, and Shoreditch. And for some green space, head to Hyde Park, Regent’s Park, or Hampstead Heath.

4. What should I see in the UK?

The UK has many other cities to explore as well, including Bristol, Brighton, Liverpool, Edinburgh, and Glasgow. 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.

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.
