What should you pack for a trip to the United Kingdom? Whether you are heading to London for a city break, exploring the Scottish Highlands, or touring the English countryside, packing the right items makes a huge difference to your comfort and convenience. This comprehensive packing list covers everything American travelers need to bring, from essential documents to clothing, electronics, money, health supplies, and what to leave at home.
The UK’s unpredictable weather, different electrical standards, and walkable cities mean your packing strategy should differ from a typical US domestic trip. Follow this guide to arrive prepared and travel comfortably throughout your stay.

Frequently Asked Questions: Packing for a UK Trip
Do I need a voltage converter for the UK?
Most modern electronics (phones, laptops, tablets, cameras) have dual-voltage chargers (100-240V) and only need a plug adapter. Check the label on your charger. Hair dryers, straighteners, and other heat appliances usually need a voltage converter or should be left at home.
What type of power plug does the UK use?
The UK uses Type G plugs with three rectangular pins. The voltage is 230V at 50Hz, compared to the US standard of 120V at 60Hz. Bring at least two UK adapters so you can charge multiple devices.
Should I bring an umbrella to the UK?
Absolutely. A compact, wind-resistant folding umbrella is one of the most essential items for any UK trip. Rain can arrive suddenly at any time of year, often as brief showers.
How much cash should I bring to the UK?
Very little. The UK is one of the most cashless societies in the world. A contactless debit or credit card covers 95% of transactions. Bring £50 to £100 in cash for small tips, street vendors, and emergencies.
Can I use my US phone in the UK?
Yes, but check roaming charges with your carrier first. For affordable data, get a UK eSIM or SIM card upon arrival. See our phone and internet guide for details.
