Using self-storage when moving house

Key takeaways

• In the UK self-storage generally costs between £30 and £250 per month depending on the size of the unit, its location and how long you need it.
• Since most facilities operate on month-to-month agreements, you won't be tied into a long-term contract if your moving schedule changes.
• Storage is usually the quiet solution when there's a break in the chain or a gap between work completion dates. It also helps when downsizing because the new house won't hold all the items from the start.
• Packing your unit with an inventory and a "front row" of essentials saves you hours of digging through boxes later.
• Some removal companies offer storage as part of their service, which can work out cheaper and simpler than sourcing it separately.

Moving day rarely lines up as neatly as the calendar suggests. Sales fall through at the last minute, completion dates get pushed back, or you find your new home is smaller than the one you're leaving. Storage quietly solves many of these headaches, but people often only think about it once the problem has arrived.

The guide explains the real cost of using self-storage, how it relates to moving into a new house, and the practical matters that no one tells you about until you're in a storage unit and have forgotten where you put the kettle.

What is self-storage when moving house?

Self-storage when moving house means renting a secure storage unit to keep some or all of your belongings while you move. It can be useful if there’s a gap between leaving your old home and moving into your new one, if you need to declutter before a sale, or if you simply don’t have space for everything straight away.

Unlike a garage or a friend's loft, self-storage facilities are built for the job. Units come in a range of sizes, from a small locker for a few boxes to a space large enough for the contents of a four-bedroom house. Most are accessible seven days a week, monitored by CCTV, and offer a choice of drive-up or indoor units, depending on what you're storing and how often you need to access it.

For movers, storage tends to get used in one of two ways. Either it's a short, practical gap-filler between one move and the next, or it's a longer-term solution while you sort out where things are actually going to live in your new home. Both are common, and neither means something's gone wrong with your move.

Why might you need storage when moving between homes?

You might need storage if your moving dates don’t line up, you’re downsizing, or your new home isn’t ready yet. It gives you a secure place to keep your belongings until you’re ready to move everything in.

The UK conveyancing process doesn't always run to schedule. According to the Law Society, the average residential transaction in England and Wales takes eight to twelve weeks from offer to completion, assuming nothing goes wrong. Mortgage delays, survey findings, longer searches, or a buyer pulling out further up the chain can all push your completion date back with little warning.

Common reasons movers turn to storage include:

• A broken or delayed chain. If the chain falls through or is delayed, you may have to leave your current home before your new one is ready. During this time, storage keeps your possessions safe while you arrange temporary accommodation.
• Downsizing. Moving to a smaller property often means you can't fit everything in straight away. Storage gives you breathing room to decide what to keep, sell or donate without having to make hasty decisions on moving day.
• Renovation work. If your new home needs work before you move furniture in, storage keeps everything out of the way of builders and dust.
• Staggered moves. Some people move into a new area before their new home is ready, perhaps renting short-term nearby, and don't want to pay to move belongings twice.

If delays in the chain are a concern, our guide to exchange of contracts vs completion explains what happens at each stage and when you become legally committed to the move. Also, compare conveyancing quotes and hire a good conveyancer so delays are caught and managed early rather than discovered at the last minute.

Pro tip: If you suspect your chain might be at risk, flag it with your conveyancer as soon as possible. A good solicitor can often negotiate a longer completion window or a temporary storage-and-rental arrangement rather than leaving you scrambling on the day.

What is the monthly cost of self-storage in the UK?

Self-storage in the UK typically costs between £30 and £250 per month, depending on unit size, location, and access. A small unit for a flat's belongings is at the lower end, while a full house pushes you towards the top.

Prices differ more than most people anticipate, and the influence of location is greater than many realise. A storage unit in central London may cost two or three times as much as a similar-sized unit in a smaller town or in a rural area. The following is a general overview of UK self-storage pricing based on typical rates:

These are approximate UK prices and can vary considerably by location, provider and unit type. Storage in London and the South East is often more expensive. Before booking, ask for a written quote and check whether VAT, insurance and any administration fees are included so you know the full cost.

Storage is only one part of the overall cost of relocating. Our guide to the cost of moving house in the UK covers removals, legal fees, surveys and other common moving expenses.

What are the factors that influence the cost of self-storage?

A few factors move the price up or down more than people expect:

• Location. Facilities in cities and affluent areas charge more per square foot than those in rural or out-of-town locations.
• Unit size and shape. Ground floor and drive-up units often cost slightly more than upper-floor units accessed by lift.
• Duration. Some providers offer discounts for longer bookings, while others charge a premium for very short stays.
• Access hours. 24-hour access facilities tend to cost more than those with restricted opening times.
• Insurance. Many facilities require you to take out their contents insurance, which is added to your monthly bill unless you can prove your own policy covers stored goods.

What is the cost of using short-term storage when moving a house?

The cost of short-term storage when moving homes is generally a bit higher per week than that of a long-term reservation, the charge typically being made in weekly or monthly amounts and requiring a minimum stay of one to four weeks depending on the company.

Most facilities use monthly rolling contracts rather than daily rates, which suits movers since you rarely know the exact day you'll need to clear a unit. Some operators offer short-term or "flexible" packages for people between moves, often with a lower minimum term but a slightly higher weekly rate.

Watch out for:

• Minimum term charges. If you only need storage for ten days but the minimum term is four weeks, you'll pay for the full month regardless.

• Deposits. Many facilities ask for a deposit equivalent to one or two weeks' rent, refundable when you vacate the unit in good condition.

• Notice periods. Some providers need a week or more notice before you move out, so factor this into your completion timeline rather than assuming you can leave on the day.

If your storage need is short, it's often cheaper to negotiate a rolling monthly contract with no long minimum term than to book a "short stay" package with inflated weekly pricing. Ask the provider which option works better for your timeframe.

How can storage help bridge the gap between moves?

Storage fills the gap between moves by providing you with a safe place to store your belongings when your sale and purchase completion dates do not match or when a delay at any stage in the process causes your move-in date to be pushed back.

This is one of the most common reasons movers reach for a storage unit, and it's rarely planned. You might exchange contracts on your sale with a completion date that falls before your onward purchase completes, or a delay further up the chain means your buyer needs to move out before your new home is legally yours. Rather than losing your buyer or your onward purchase while everyone waits, storage lets you vacate on schedule and move into rented accommodation or stay with family, keeping the whole chain intact.

Many removal companies offer short-term storage as part of their service, meaning your belongings can go straight from your old home into storage. When you compare removal companies, ask whether storage can be included in the same quote.

Pro tip: If your chain is at risk of breaking or slipping, talk to your solicitor about a "completion by instalments" clause or a short-term rental agreement with the buyer. It's not always possible, but it can occasionally avoid the need for storage altogether.

House removal and storage - should you use one company for both?

Arranging one company to carry out both the removal of your home and the storage of your belongings can simplify the process of moving and is usually cheaper than making separate bookings, since your possessions will be handled only once and transported directly to the storage facility.

That said, it's not automatically the right choice for everyone. Here's how the two options generally compare:

If you know you'll need to dip into your storage unit regularly, an independent self-storage facility with drive-up access tends to work better. If it's purely a short gap between your old home and your new one, letting your removal company handle both can save time and reduce the risk of damage from extra handling. Our guide to choosing the right removal company covers what to check before booking, including insurance, storage, packing services and what is included in the quote.

What size storage unit do you need when moving house?

The amount of space most people need is 50 square feet for a one-bedroom flat, 75 square feet for a two-bedroom house, and 100 square feet or so for a three-bedroom or larger property, although this will depend on how much furniture you own.

As a rough guide:

• Studio or 1-bed flat: 25 to 50 sq ft, roughly the size of a small van.

• 2-bed house: 50 to 75 sq ft.

• 3-bed house: 75 to 100 sq ft.

• 4-bed house or larger: 100 sq ft upwards, sometimes needing two units.

Since most reliable facilities provide a free size guide or will either come to you or ask that you send them photos in order to recommend the correct unit, it's best not to make an arbitrary guess. Waste money each month if you choose a unit that's too large, but if you underestimate you'll have a stressful situation on the day you move when all the items won't fit.

The best way to pack a storage unit for easy retrieval

Pack a storage unit by grouping items by room, labelling every box clearly, keeping an inventory list, and placing frequently needed items near the door so you don't have to unpack the entire unit to find one thing.

A storage unit is only useful if you can actually find what you need when you need it. A few practical habits make a huge difference:

• Build from the back, not the front. Put heavy, rarely needed items (out-of-season decorations, spare furniture) at the back. Put anything you might need in the next few weeks near the door.

• Label every box on more than one side. Boxes get stacked and turned, so a label on just the top is often invisible once everything's in place.

• Make a record of everything. Using a simple spreadsheet or even a list in a notes app showing the contents of each numbered box will prevent you from having to climb over furniture in order to remember where the paperwork is.

• Use shelving where possible. Vertical space is free space. Many facilities allow freestanding shelving units, which stop you having to stack fragile boxes on top of each other.

• Leave a walkway. Don't pack wall to wall. A narrow path down the middle means you can reach anything without unloading the whole unit.

• Protect furniture properly. Wrap sofas, mattresses and wooden furniture in breathable covers rather than plastic sheeting, which can trap moisture and cause damp or mould over time.

Pro tip: Photograph the inside of each box before sealing it. It takes seconds and means you never have to open three boxes guessing which one has the phone chargers.

What items should not go into self-storage?

You shouldn't store flammable materials, perishable food, live plants, pets, and valuable items which are irreplaceable such as passports or jewellery in a self-storage unit since most storage facilities have strict rules about prohibited items for safety and insurance reasons.

Common exclusions include:

• Flammable liquids, gas canisters and fireworks

• Perishable or fresh food

• Live plants and animals

• Firearms and ammunition

• Illegal or hazardous substances

• Highly valuable or irreplaceable items such as passports, wills and family heirlooms, which are usually better kept with you or in a bank deposit box

Before you pack, be sure to check the particular terms of your facility, as some of them do place limitations on items such as car tyres or certain chemicals used in hobbies and DIY activities.

How long can you keep belongings in storage during a move?

Most self-storage companies do not have a fixed maximum period and instead operate on a month-to-month basis, so you can keep your belongings for as long as you want, whether that be a few weeks or several years, as long as you give notice to terminate the agreement.

Such flexibility is one reason storage suits movers so well. You're not locked into a fixed end date, which matters when conveyancing timelines move. That said, review longer stays every few months, both for cost (are you still paying for a unit larger than you need?) and condition (are stored items holding up well, particularly anything electrical or upholstered?).

Do you need insurance for self-storage?

Yes, the majority of self-storage facilities do require you to have insurance for the items in your unit, either through a policy that they provide or via your current home contents insurance, on the condition that this explicitly includes items kept in storage.

Since standard home contents insurance does not always include items that are kept off-site, it's a good idea to check the exact wording of your policy rather than simply assuming that you are covered. In the case where your policy does not cover storage, the storage facility will typically provide its own insurance as part of the booking, with the cost being based on the declared value of the items you are storing. This is a legal requirement at most reputable storage facilities in the UK, as it is necessary for protecting you and in order to comply with the conditions of their own building insurance.

How do you find and compare storage options when moving house?

To compare storage options, check prices at several local storage facilities, ask removal companies whether their service includes storage, and read recent reviews on access, security, and customer service before booking.

A few practical steps worth taking:

• Get quotes from at least two or three facilities local to your old and new address, since prices vary significantly even within the same town.

• Ask your removal company whether storage is available as an add-on and compare the total price with standalone storage. Our guide to getting accurate removal quotes explains how to compare quotes properly and check what is included.

• Check access hours, security measures (CCTV, individual unit alarms, gated entry) and whether the facility offers 24-hour access if you think you'll need it.

• Read recent customer reviews rather than relying on star ratings, particularly about how facilities handle damp, pests or damage claims.

If your storage need stems from a conveyancing delay rather than a straightforward move, it's also worth comparing conveyancing solicitors through our conveyancing quote tool to see whether a faster or more communicative solicitor could shorten the gap in future transactions.

Final summary

Storage can make moving house much easier when your dates don’t quite line up, you’re downsizing, or your new home isn’t ready for everything straight away. The cost will depend on how much space you need and where you live, but storage is usually flexible enough to work around changes to your moving dates.

If you think you’ll need storage, it’s worth comparing removal companies that can handle both the move and the storage. You can compare removal company quotes through Moving Compared and see what options are available near you.
