What Is Self Storage?

Self storage stands for “self-service storage.” It is a service where people and businesses can rent a secure space to keep their belongings, equipment, or stock when they run out of room at home or at work. Think of it as an extra room outside your property that you can rent and use whenever you need. Self storage is becoming more popular in the UK as it helps people and companies handle all sorts of storage problems without having to throw things away.

With self storage, you alone have access to your items, unlike traditional warehouses where staff may go through your stuff. Only you have the key for your unit, so your privacy and security are kept. The idea began in Texas in the late 1960s due to homes not having basements. By 1979, the first UK self storage centre opened in London thanks to Doug Hampson, the “father of UK self-storage.” There are now over 2,000 self storage locations with over 45 million square feet of space in the UK.

How Does Self Storage Work?

How Does Self Storage Work?

Using self storage is simple. You rent a space (a “unit”) in a facility. These units come in many sizes, from small lockers to big rooms that can fit the contents of an entire house. Rentals are usually paid monthly, but longer rentals are available too. This means you can store things for a short time or for many months.

After choosing a unit and signing an agreement (which states how long you can use it and how much it costs), you pay a monthly fee. The storage space is yours to use, and you keep it locked, usually with your own padlock. Access is allowed during the opening hours, which are often long, sometimes even 24/7. You are responsible for moving your things in and out, but many facilities offer trolleys, loading equipment, and covered areas to help, especially useful during rainy weather.

What Can You Store?

Self storage is useful for both personal and business needs. Here are some examples of what you can keep in a storage unit:

  • Furniture and household items
  • Seasonal decorations (for example, Christmas trees or garden sets during winter)
  • Sports gear and bicycles
  • Books, old files, or student materials

Businesses often use self storage for:

  • Extra stock or inventory
  • Archived paperwork or records
  • Equipment
  • Office furniture during moves

There are some things you cannot store, like flammable liquids, explosives, perishable foods, illegal goods, or living things such as animals or plants. Always ask the facility what is not allowed.

Who Uses Self Storage?

Self storage is for anyone-individuals, families, students, and businesses. The main life events that create a need for storage are known as the “4Ds”:

  • Death
  • Divorce
  • Downsizing or moving (called Delimitation)
  • Big life changes (for example, marriage bringing two households together)

People rent units when moving homes (especially if there’s a gap between moving out and moving in elsewhere), during house renovations, to keep extra items when going to a smaller place, or when more space is needed. Businesses save money by storing goods and paperwork offsite rather than paying high rent for extra commercial space. Students also use self storage during holidays, so they don’t have to move everything back and forth.

Main Reasons for Using Self Storage

Moving House or Renovating

One of the most common uses is during house moves. If you need to leave your home before your new one is ready, or if you’re decorating, storage offers a safe place for your furniture and boxes. This keeps your things clean and safe, and helps you manage the move at your own pace.

Renovating your home can create dust and mess. Putting your valuables in storage protects them and gives builders more space to work, which can speed up the process.

Business Storage Needs

Businesses-especially small ones and online shops-use storage for keeping extra goods, records, or furniture. Self storage is cheaper and easier to adjust than renting warehouse space. You can increase or decrease your space as your business changes. This helps you avoid paying for space you do not need and lets you work more efficiently.

Some facilities also accept deliveries or offer shelves and equipment help for businesses.

Storage for Students and Seasonal Belongings

Students often move at the end of every term. Self storage lets them keep their belongings close to university instead of taking everything home. It saves time, effort, and moving costs.

Seasonal items like Christmas decorations, garden furniture, sports equipment, and seasonal clothes can take up needed space at home. Self storage keeps these items out of the way but easy to get when needed.

What Should You Expect in a Self Storage Facility?

Security

A good facility keeps your belongings safe. Look for these security features:

  • 24/7 CCTV cameras
  • Gated or keypad entry
  • Individual unit alarms
  • Good lighting everywhere
  • On-site staff and regular patrolling
  • Strong fencing and fire alarms

Access and Use

Choose a facility with opening hours that fit your needs. Most places offer long hours, some are open all the time. Also, check for extras like:

  • Free trolleys and carts
  • Covered loading areas
  • Easy parking
  • Comfortable customer area (some provide free Wi-Fi and drinks)

Insurance

Insurance is needed for your items in storage. Most facilities can offer it for you, but you can also contact your insurer to see if your home or business insurance covers self storage. It’s your responsibility to make sure your items are insured.

Unit Sizes and Flexibility

Storage units come in sizes from small lockers to spaces big enough for a lorry’s load. Here is a sample table:

Unit SizeApprox. What It Holds
5 sq ftBoxes or personal items
25 sq ftHalf a studio flat
50 sq ftContents of 1 bedroom flat
100+ sq ftContents of 2+ bedroom house

Most facilities let you change units if you need more or less space, so you only pay for what you use.

Customer Help and Extra Services

Helpful staff make the process smoother. Good facilities will help you choose the right size, offer packing tips, explain the agreement, and discuss insurance.

They also can sell boxes, bubble wrap, locks, or help with van rental and removals. Some offer free collection for new customers or help businesses with deliveries and shelving.

How to Choose the Right Self Storage Unit

Comparing Unit Sizes

Choosing the right size stops you from paying too much for empty space or from squeezing your things too tightly. Many storage companies provide online calculators or staff advice to help you decide.

  • Small units: Best for boxes, books, sports equipment
  • Medium units: Contents of a 1-bedroom flat
  • Large units: Full house contents or business stock

You can stack items to make the most of vertical space.

What to Think About Before You Rent

  • How long will you need storage? (Short-term or long-term?)
  • What kind of items are you storing? (Do you need climate control?)
  • How often will you need to access your stuff?
  • How close is the facility to your home or business?
  • Is the facility clean and well-kept?

Rental Agreements and Costs

The rental agreement sets the rules for your storage. Read it carefully to understand:

  • Rental length (usually monthly, with some minimum stays)
  • Payment times and how to pay
  • How much notice you must give before leaving
  • Who can open your unit (usually only you)
  • What fees or extra costs there may be (insurance, late payment, etc.)

  • Flammable liquids (like petrol, paint thinners)
  • Explosives
  • Food that can spoil

Can Other People Get Into My Unit?

Normally, only you can enter your storage unit because you provide the lock and key. If you want someone else to have access, you need to give written permission to the facility. Employees will usually only access your unit for emergencies or if you haven’t paid your rent as agreed.

Do I Need Insurance?

Yes. Self storage facilities do not cover your items unless it’s their fault something is lost or damaged. You should buy separate insurance or check if your home or business coverage includes storage units. The price depends on how much your items are worth.

What if I Lose My Key?

If you lose your key, staff can help you cut off the lock, but you must show ID to prove the unit is yours. You will need to bring or buy a new lock for your unit.
