London rewards the well-packed traveller and quietly punishes the badly packed one. This is a city where you will walk further than you expect, where the weather can change three times before lunch, where pavements are old and uneven, and where the gap between a comfortable day and a miserable one is often a single item left at home: a waterproof jacket, a pair of broken-in shoes, or the right plug adapter. Packing well is not about bringing everything you own. It is about bringing the right things, in the right case, for the trip you are actually taking.
The eight mistakes below are the ones visitors make again and again, and each one is easy to fix once you know it. Read them before you zip your case, and you will arrive lighter, drier, more comfortable, and far less likely to spend your first day in London shopping for things you already own at home. If you are planning a first visit, it also helps to read our guide for first-time visitors to London, which covers the practicalities of getting around the city alongside what to see.
Before You Pack a Single Thing
The best packing starts before the case comes out of the cupboard. First, check the forecast a day or two before you travel, not two weeks ahead, when London weather predictions are little more than guesswork. Second, look honestly at your itinerary. A weekend of museums, parks and markets needs very different packing from a week that includes a smart dinner, a theatre night and a day trip to the coast. Third, weigh your empty case. A heavy case eats into your airline allowance before you have packed a single shirt, and a case you cannot lift comfortably onto a train is a case you will resent at every station staircase.
A useful rule is to lay everything out on the bed first, then remove a third of it. Most travellers pack for imagined emergencies rather than real plans: three extra jumpers for a cold snap that never comes, four pairs of shoes for outfits that never get worn, a guidebook for a city where a phone does the same job. Every item you remove is weight you will not carry, space you will not need, and time you will not spend repacking in a hotel room. Pack for the trip you have planned, not the trip you might have planned.
The 8 Packing Mistakes to Avoid
1. Packing the wrong shoes
This is the mistake that hurts most, quite literally. London is a walking city. Even with excellent public transport, you will walk to stations, around museums, through parks and along river paths, and you will do much of it on old pavements, cobbles and uneven steps. New shoes, stiff boots, thin-soled fashion trainers and high heels are all recipes for blisters by lunchtime on day one. The fix is simple: pack comfortable, broken-in walking shoes with good grip, and make sure they are at least shower-resistant, if not fully waterproof. Save one smarter pair for evenings out, and only if your itinerary genuinely includes one. Your feet will carry you through the whole trip, so they deserve first priority in the case, not last.
2. Ignoring London’s unpredictable weather
London weather has a sense of humour, and it is rarely kind to the unprepared. A bright morning can turn into a sharp shower by midday, and a warm afternoon can end with a chilly evening wind along the Thames. Travellers who pack only for the season they expect, a sundress and sandals for August, or a single heavy coat for March, are caught out again and again. The fix is layers. Pack a light waterproof jacket whatever the month, a warm mid-layer such as a jumper or fleece, and clothes you can add or remove through the day. Layers also solve the indoor problem: the Tube can be very warm even in winter, while museums and churches can be cool, so being able to peel off or add a layer keeps you comfortable everywhere.
3. Overpacking, or underpacking, your clothes
Both extremes cause trouble. Overpacking leaves you dragging a case you cannot lift, paying excess baggage fees, and living out of a chaotic pile in a small hotel room. Underpacking leaves you wearing the same damp shirt twice or buying emergency clothes at London prices. The fix is to plan outfits, not items. Choose a small colour palette so everything works with everything else, plan one outfit per day plus one spare, and include one smarter outfit only if your plans call for it. Most London hotels and many apartments have laundry facilities, and a small bottle of travel detergent weighs almost nothing. Packing cubes or simple rolling will also keep a modest case organised and wrinkle-free.
4. Bringing an oversized suitcase
A huge case feels generous at home and becomes a burden the moment you reach London. Narrow Tube escalators, crowded buses, small hotel lifts, and the stairs at older stations all punish oversized luggage, and many budget hotel rooms have barely enough floor space for a large case, let alone two. The fix is to choose the smallest case that fits your planned outfits, ideally a cabin-sized case for a short trip, and to test it before you leave: can you lift it, carry it up a flight of stairs, and wheel it one-handed? If not, it is too big. A smaller case also forces better packing decisions, which is a benefit disguised as a restriction.
5. Forgetting a proper day bag
Your suitcase stays at the hotel. Your day bag carries everything you actually need between morning and night: water, snacks, a phone charger, a waterproof layer, tickets, a map, and any medication. Travellers who try to manage with coat pockets end up juggling belongings, losing tickets, and getting caught in rain with their jacket back at the hotel. The fix is a small, comfortable day bag, ideally a crossbody bag or a compact backpack that closes securely. A bag with a zipped inner pocket for a passport and cards is worth its weight, and a bag you can wear in front of you on a crowded Tube is safer than an open tote. Pack it the night before, and your days will run far more smoothly.
6. Assuming your hotel provides everything
Many visitors arrive expecting hotel toiletries, hairdryers, irons and adapters to be waiting for them, and many are disappointed. London hotels vary enormously: some provide everything, others provide almost nothing, and budget rooms and rented apartments often provide very little beyond bedding and towels. The fix is to check what your accommodation actually offers before you travel, and to pack the essentials regardless. Bring your own toiletries in travel sizes, any medication you need, a phone charger, and a small sewing kit if you rely on one. If you need a hairdryer or an iron, confirm it in advance rather than discovering its absence at midnight before an early start.
7. Travelling without backup copies of important documents
A lost passport, a stolen wallet, or a phone that dies at the wrong moment can turn a small problem into a trip-ruining one if you have no backup. The fix takes five minutes and costs nothing. Photograph or scan your passport, travel insurance, flight details, hotel confirmations and bank card numbers, and store the copies somewhere separate from the originals: in an email account you can access from any device, or in a secure cloud folder. Carry a paper copy of your passport details and your insurance number in your day bag as well. If the worst happens, you will have everything an embassy, an airline or an insurer needs, without having to remember it under stress.
8. Forgetting UK plug adapters and voltage differences
The United Kingdom uses the three-pin Type G plug and a 230-volt supply, which differs from much of Europe, North America and Asia. Visitors who arrive with a phone charger that does not fit a UK socket spend their first evening hunting for an adapter instead of enjoying the city, and travellers with hair tools or other electrical items may find their devices do not work safely on UK voltage at all. The fix is to pack at least one UK adapter, ideally two, and to check whether your devices are dual-voltage before you travel. Most modern phone and laptop chargers are dual-voltage and need only an adapter, not a converter, but heat appliances such as hair straighteners often are not, so check the label. A small power bank, charged before you leave, is also a wise addition for long days of sightseeing.
Packing for Every Season
Once the eight mistakes are avoided, a few seasonal adjustments will fine-tune your case. In winter, prioritise warmth and waterproofing: a proper coat, a hat and gloves, and waterproof shoes matter more than extra outfits, since you will spend much of the day outdoors between heated interiors. In spring and autumn, layers are everything, with a waterproof jacket and a scarf doing more work than any single heavy item. In summer, pack light layers, sun protection and a refillable water bottle, but do not leave the rain jacket at home: London summer showers are a regular feature, not an exception, and a compact umbrella weighs almost nothing.
Whatever the season, a few items earn their place on every trip. A reusable water bottle saves money and keeps you hydrated on long walking days. A small umbrella or a packable rain jacket protects you from the city’s famous showers. Comfortable socks, blister plasters and a basic first-aid pouch weigh little and rescue many days. And a phone charger plus a portable battery will keep your maps, tickets and camera working from the first museum to the last dinner. These are not glamorous items, but they are the ones experienced London travellers never leave behind.

A Simple London Packing Checklist
Use this checklist as a final pass before you close the case. Clothing: comfortable walking shoes, one smarter pair if needed, a waterproof jacket, layers for warmth, and outfits planned around a single colour palette, with one spare set. Day bag: water bottle, snacks, phone charger and power bank, tickets, a map or a charged phone, and any medication. Documents: passport, travel insurance details, booking confirmations, and backup copies stored separately. Electricals: UK plug adapters, dual-voltage check completed, and chargers for every device you are bringing. Extras: a small umbrella, sun protection in summer, a hat and gloves in winter, and blister plasters, just in case.
If every item on that list is ticked and your case still closes easily, you have packed well. If the case will not close, or you cannot lift it comfortably, go back to the bed, remove the items you packed for imaginary occasions, and try again. The best London trips are the ones where luggage is forgotten by the second morning, because it is working so well that you never have to think about it.
Travelling with children, or as a larger group, calls for one extra habit: give every traveller their own small bag for the day, even if you are sharing a suitcase at the hotel. A child with their own water bottle, snack and rain jacket is far happier than a child whose things are buried in an adult’s bag, and an adult whose essentials are always to hand is far calmer on a crowded station platform. It also spreads the risk: if one bag is misplaced, the whole group is not left without water, tickets or medication. Pack a spare set of clothes for younger children in your own day bag as well, since spills, sudden showers and muddy parks are all part of a London family trip, and a quick change can rescue an afternoon that would otherwise end early. Finally, agree a simple meeting point with your group before you enter a busy station or attraction, and keep your phone charged, so that even if the group splits up, regrouping takes minutes rather than a stressful hour.
Good to Know
A few practical points will make your arrival smoother. London’s airports and major stations all have shops selling adapters, umbrellas and basic toiletries, but prices there are high and queues can be long, so buying before you travel is almost always cheaper. If you are travelling with only hand luggage, remember the liquids rule for flights: containers of 100 millilitres or less, in a single transparent bag, for anything you carry through security. Put larger toiletries in checked luggage or buy them after arrival.
Finally, keep valuables, medication and a change of clothes in your hand luggage or day bag, not in a checked case. Delayed luggage is rare but it happens, and arriving in London with your essentials on your person turns an inconvenience into a minor delay rather than a ruined first day. Pack a little thoughtfully, keep your documents backed up, and London will do the rest: it is a city that rewards walkers, and with the right shoes and the right layers, you will be ready to enjoy every step of it.
FAQ
What shoes should I pack for London?
Comfortable, broken-in walking shoes with good grip and at least some water resistance. London involves a great deal of walking on old pavements and cobbles, so new shoes or heels will quickly cause blisters. Pack one smarter pair only if you have evening plans that call for it.
Do I need a rain jacket in summer?
Yes. London showers happen in every month, including summer, and a light packable rain jacket weighs almost nothing. It is far more useful than an umbrella alone on a windy day, and it doubles as an extra layer on cool evenings.
How big a suitcase should I bring to London?
The smallest case that fits your planned outfits. A cabin-sized case suits most short trips, while a medium case is plenty for a week. Oversized cases are difficult on Tube escalators, buses and station stairs, and they can overwhelm small hotel rooms.
What plug adapter do I need for the UK?
The UK uses the three-pin Type G plug on a 230-volt supply. Pack at least one Type G adapter, and check that your devices are dual-voltage before travel. Most phone and laptop chargers are, but many heat appliances are not.
Should I carry my passport with me every day?
Carry a copy of your passport details in your day bag and keep the original locked safely at your accommodation, unless you need it for a specific purpose such as a day trip or an age check. Store a digital backup separately so you can access it from any device if needed.
What should I keep in my day bag in London?
Water, snacks, a phone charger and power bank, tickets, a waterproof layer, a map or charged phone, and any medication. A secure, zipped bag worn across the body is the most practical choice for crowded transport and busy streets.
