The problems that slow a move down usually start before the first box reaches the van. The top mistakes on moving day are rarely dramatic. More often, they are small oversights that build into delays, extra lifting, misplaced items and unnecessary stress.

Whether you are moving from a London flat, relocating an office, or arranging a smaller man and van job, good preparation matters more than most people expect. A well-run move is not about rushing. It is about making sure the right things happen in the right order.

The top mistakes on moving day usually start the night before

One of the most common issues is leaving too much until the last minute. People often assume they can finish packing in the morning, take apart furniture quickly, or sort out keys while the movers are loading. In practice, those final jobs take longer than expected.

If boxes are still open when the team arrives, the move slows down immediately. Loose items need to be gathered, fragile things are harder to protect properly, and rooms become harder to clear in a sensible order. The same applies to furniture that still needs dismantling. Some items are straightforward, but beds, desks and wardrobes can easily take longer than planned.

The safer approach is to treat the evening before as your deadline. By then, most packing should be done, furniture should be ready if it needs to come apart, and your essentials should be set aside. A few final bits on the day are normal, but a half-finished home is where many delays begin.

Poor labelling causes more trouble than people think

Boxes without clear labels nearly always create extra work. On the old side of the move, they slow loading because nobody knows what needs special handling. At the new address, they cause confusion about where items should go and what needs unpacking first.

This is especially unhelpful in larger homes, shared houses, offices and student moves where several people may be involved. A box marked only with a name or a vague note such as “misc” tells you very little when you are trying to unload efficiently.

A simple room label is usually enough, but it helps to add a brief note if the contents are fragile or needed urgently. Kitchen, bathroom, main bedroom and cables are much more useful than general descriptions. If you are moving into a building with stairs or limited access, clear labels matter even more because you want each box handled once, not moved around later.

Packing the wrong items together

Another version of the same mistake is mixing heavy and delicate items in one carton, or overfilling large boxes with books and files. A box that is too heavy is harder to carry safely and more likely to split. A box with loosely packed fragile contents may arrive intact on the outside and damaged inside.

Smaller boxes are better for books, paperwork and tools. Medium cartons suit general household items. Lighter, bulkier things such as bedding and clothes can go in larger boxes. That sounds basic, but getting box weight right makes a noticeable difference on moving day.

Underestimating access problems

In London, access can shape the whole move. Narrow roads, restricted parking, controlled entry systems, upper-floor flats and tight staircases all affect loading times. Yet one of the top mistakes on moving day is assuming the van can simply stop outside and everything will run to plan.

If parking needs to be arranged, it is best done in advance. If permits, suspended bays or concierge access are involved, leaving it until the morning can create avoidable delays. Even where formal permits are not required, it still helps to think about where the vehicle can wait legally and safely.

Inside the property, difficult access also needs honest planning. A sofa that barely fitted when you moved in may not come out as easily as you remember. Long hallways, small lifts and shared entranceways can all slow the job down. This does not mean the move cannot be done, but it does mean timing and vehicle choice should reflect reality.

Choosing the wrong van size

A van that is too small often looks cheaper at first glance, but if it means multiple trips, the overall job may take longer and cost more. A van that is far too large can also be impractical if access is limited.

The right choice depends on volume, furniture size, parking conditions and distance between properties. For a small flat or a student move, a man and van may be enough. For a family home or office relocation, a larger vehicle is often more efficient. The mistake is guessing rather than planning.

Not keeping essentials separate

One of the most frustrating moving day problems is packing away the things you need most. Keys, chargers, medication, kettle, mugs, toilet roll, cleaning products, documents and basic tools often disappear into general boxes just when they are needed.

This is not only inconvenient. It can hold the move up. If the new property needs a quick clean before unloading, or if someone needs tenancy paperwork, the lack of an essentials bag becomes more than a minor annoyance.

Keep one clearly marked set of essentials with you rather than loading it into the van with everything else. For families, this should also include snacks, drinks, nappies if needed, and a change of clothes. For office moves, add important devices, access cards and anything needed to get staff working quickly.

Forgetting about utilities and basic checks

People naturally focus on boxes and furniture, but practical checks matter too. Before leaving the old property, meter readings should be taken where relevant, cupboards checked, appliances emptied, and windows closed. At the new place, it helps to know whether electricity, water and internet are ready to use.

The mistake here is assuming these details will sort themselves out. They rarely do. Arriving late in the day to find no kettle, no power in part of the property, or no idea where the stopcock is can make a straightforward move feel much harder than it needs to be.

This is one area where a written checklist works well. Not because moving needs to be overcomplicated, but because tired people forget obvious things.

Trying to direct every detail at once

On moving day, many customers understandably want to keep an eye on everything. The problem comes when one person is answering calls, looking after children, speaking to estate agents, checking boxes, deciding where furniture goes and searching for missing paperwork all at the same time.

That split attention can lead to muddled instructions and repeated questions. If possible, decide in advance who will handle access, who will keep important documents and who will be the main point of contact during the move. In a business move, nominate one person who can make quick decisions about layout, equipment and priority items.

Calm communication saves time. If the movers know who to speak to and what the plan is, loading and unloading tend to go more smoothly.

Leaving cleaning and clearing too late

Another common problem is trying to clean each room only after it has been emptied, while the move is still going on. In some homes that works, but in many cases it creates bottlenecks. People end up waiting to carry items through hallways or onto stairs because someone is vacuuming, mopping or sorting leftover bits.

A better approach is to keep cleaning realistic. Deal with obvious jobs in advance, clear rubbish before the move, and leave only a final wipe-down for the day itself. The same goes for lofts, sheds, balconies and cupboards that are easy to forget until the van is nearly full.

Ignoring timing between collection and key release

Not every move is a simple door-to-door handover. Sometimes the old property must be vacated by a certain hour, while access to the new one depends on estate agents, landlords, building managers or completion times. One of the top mistakes on moving day is treating those timings as fixed when they are often less predictable.

If there is any uncertainty about key collection or property access, build in some flexibility. This matters particularly in London, where traffic, parking and building rules can already affect the schedule. Delays do not always mean anyone has done something wrong, but they are easier to manage when expected rather than ignored.

For that reason, it helps to confirm arrangements the day before and keep phones charged. A little communication at the right moment can prevent a long wait outside with a loaded van.

Rushing the final walk-through

When a property finally looks empty, most people want to shut the door and move on. That is understandable, but it is often when smaller items get left behind. Chargers in sockets, shelves in cupboards, shoes behind doors, paperwork in drawers and food in the fridge are all common.

A proper final check should be slow enough to catch the obvious and quiet enough to notice what is missing. Open built-in storage, look behind curtains, check outdoor areas and take one last look at the bathroom and kitchen. These are the places where forgotten items tend to hide.

At Removals Company, we see the same pattern time and again: the smoother moves are not always the smallest ones, but the best prepared ones. A calm moving day usually comes down to realistic packing, clear labelling, honest timing and simple communication. If you can get those basics right, the whole day tends to feel far more manageable.
