London Packing List: What Every US Visitor Needs to Bring

Sharing is caring!

Getting your London packing list right before you travel makes a genuine difference. You will walk 8–12 miles per day across cobbled streets, parks and river walkways. The weather can shift three times in a single afternoon. And London is large — there is no quick dash back to your hotel when you are on the other side of the city. This guide covers everything you need, from clothing layers to power adaptors, so you can pack confidently and travel light.

The good news is that you do not need to overpack. London has excellent shops for almost anything you might forget. Boots, Marks & Spencer, and Primark are on almost every high street. For a complete overview of everything to plan before you arrive, read our guide to planning a trip to London from the US.

Clothing for London’s Unpredictable Weather

London is famously wet, mild and overcast. It rarely gets very hot or very cold — but it can rain on any day of the year, including August. The key to packing well is layers. Not heavy items, but versatile pieces you can add or remove throughout the day as conditions change.

Spring and Summer (March to August)

Spring and early summer bring temperatures between 10°C and 22°C (50°F to 72°F). Sunny mornings often give way to afternoon showers. Warm spells arrive in July and August, but they are never guaranteed.

Pack for spring and summer:

• 4–5 lightweight tops (T-shirts, blouses or linen shirts)
• 2 pairs of lightweight trousers or jeans
• 1 smart-casual outfit for evening restaurants or theatre
• A light waterproof jacket (not a large umbrella — umbrellas are awkward on the Tube)
• A light scarf or cardigan for cooler evenings

Never travel to London in summer without a waterproof layer. Even in brilliant sunshine, carry it with you every day. You will be glad you did.

Autumn and Winter (September to February)

Autumn is one of London’s most beautiful seasons — crisp mornings, golden parks, and fewer tourists. Temperatures drop to between 3°C and 14°C (37°F to 57°F) from November onward. Snow is rare and light when it does arrive.

Pack for autumn and winter:

• A warm coat (wool or padded — nothing too bulky for public transport)
• 2 jumpers or fleece layers
• Thermal base layers for December and January visits
• Dark trousers and jeans
• Warm socks, a hat and a scarf
• Waterproof boots or weather-resistant shoes

What to Wear for London Evenings

London’s dress code depends on where you go. The West End — Covent Garden, Mayfair, the theatres — is smart-casual. Shoreditch and Hackney are relaxed and creative. Soho sits somewhere in between.

One versatile evening outfit goes a long way. Dark trousers or a dress, a blazer or smart jacket, and clean shoes cover most restaurants and shows in the city. There is no need to pack formal wear unless you have a specific black-tie occasion planned.

Shoes: The Most Important Thing You’ll Pack

This deserves its own section. You will walk more in London than you expect. Westminster Bridge, Hyde Park, the South Bank, Carnaby Street, Camden Market, Notting Hill — the distances between these places add up fast. Cobblestones, Tube staircases and uneven pavements are hard on feet that are not ready for them.

Walking Shoes Are Non-Negotiable

Bring shoes you have already broken in. New shoes on a London trip almost always cause blisters by day two.

Pack three pairs maximum:

• 1 pair of well-worn walking shoes or trainers
• 1 pair of smarter shoes for evenings (comfortable enough to stand in for three hours)
• 1 pair of flip-flops or slippers for your accommodation

More than three pairs adds unnecessary weight. London has a shoe shop on nearly every corner if you genuinely need something extra.

Power Adaptors and Tech Essentials

The UK uses Type G plugs — the large three-pin kind. US plugs are incompatible, and UK voltage runs at 230V compared to the US standard of 110–120V.

What You Need for UK Power

Most modern devices are dual-voltage. Look for “100–240V” printed on your charger. If you see this, you only need an adaptor — not a voltage converter. Most phones, laptops and camera chargers fall into this category.

Pack:

• 1–2 UK Type G travel adaptors
• A multi-port USB charger to run several devices from one adaptor
• A portable power bank for long days out across the city

Do not rely on your hotel to supply adaptors. Many do not carry them, and buying one at Heathrow costs significantly more than ordering one before you travel.

Staying Connected in London

US mobile phones work in the UK. Check your carrier’s international plan before departure. If roaming costs are high, buy a UK pay-as-you-go SIM card on arrival from O2, EE or Three — around £10 covers a week of data.

Alternatively, set up a UK eSIM before you travel. Airalo and similar services sell UK eSIMs for around $10–15 for a week. They activate the moment you land.

Money, Documents and Pre-Trip Essentials

The UK uses British Pounds (GBP). US dollars are not accepted in shops, restaurants or on public transport. You will need to exchange currency or use a card.

Cards and Currency in London

Almost everywhere in London accepts contactless payment — including the Underground, buses and most market stalls. Visa and Mastercard work universally. American Express is accepted at most larger venues but not all smaller shops and cafés.

Use a travel card with no foreign transaction fees. Revolut and Wise are popular choices for US visitors. Standard US bank cards charge 2–3% on every foreign currency transaction. Over a week in London, that adds up. Read our detailed London travel budget guide for a full breakdown of what things actually cost.

Carry a small amount of GBP cash — £50–100 covers street markets, independent cafés and smaller shops.

Essential Documents to Pack

US citizens do not need a visa for visits to the UK of under six months. You do need a valid passport with at least six months’ validity remaining.

Pack:

• Your passport (store a photo of it separately in the cloud as a backup)
• Travel insurance documentation
• Printed or downloaded hotel booking confirmations
• Any prescription medication in its original, clearly labelled packaging

Travel insurance is strongly recommended. UK emergency care is available to visitors, but follow-up treatment and prescriptions carry costs. A basic one-week policy costs $30–60 and gives complete peace of mind.

What to Leave at Home

Knowing what not to pack is as important as knowing what to bring.

Leave at home:

• A large umbrella — use a compact folding one, or rely on your waterproof jacket
• Heavy guidebooks — download offline maps and save guides on your phone instead
• More than three pairs of shoes — four or more is always too many
• Formal wear — unless you have a specific black-tie event, it will not be needed
• Duplicate toiletries — London’s Boots and Superdrug pharmacies stock everything

Pack light. A smaller bag makes the Underground far easier. Tube escalators are steep, platforms are busy, and lifts are not always in service. A compact, well-organised bag lets you move freely between Westminster, Camden, South Bank and Notting Hill without the added stress.

Frequently Asked Questions About Packing for London

What is the best way to pack for London’s weather?

Pack layers for any time of year. A waterproof jacket, comfortable walking shoes, and versatile tops form the core of any London packing list. London weather is mild but changeable — layers give you the flexibility to handle sunshine, showers and cool evenings all in the same day.

Do I need a power adaptor for London from the US?

Yes. The UK uses Type G three-pin plugs, which do not fit US devices. You need a UK travel adaptor. Check that your charger says “100–240V” — if it does, you only need the adaptor, not a voltage converter. Most modern phones and laptops are dual-voltage and handle UK power safely.

How many days’ worth of clothes should I pack for London?

For a five to seven-day trip, pack for five days. London’s streets are clean, most hotels and Airbnbs provide access to laundry facilities, and laundromats are easy to find. Overpacking is one of the most common mistakes first-time visitors make — extra clothes add weight on a trip that involves a great deal of walking.
