Hidden costs of self-storage

The advertised rate is a starting point. Check the extras, the billing cycle and the exit terms before you choose a unit.

The useful bits, first

  • Compare the standard rate as well as the opening offer.
  • Include protection, admin and lock costs.
  • Check minimum terms, notice and refundable deposits.

Start with the clock, not the discount

The most expensive misunderstanding is free. A four-weekly price looks like a monthly price and is not one. There are 13 periods of four weeks in a 52-week year. Twelve payments leave you about a month short. The four-weekly page uses a worked example: £85 every four weeks is about £92.08 a calendar month, because 85 × 13 / 12 = 92.0833…. That £85 is not a survey of prices. It is a sum you can repeat with the figure on your own quote.

Weekly billing has the same shape with a different multiplier, 52 instead of 13. A price that is already per calendar month does not need converting. Until all three are on one clock, “cheaper” is a typesetting opinion. The true cost calculator will not let you subtract them raw. You pick the period for each quote.

The rate after the offer

Introductory prices are a real part of the market and a poor place to stop reading. Half price for a few weeks, a nominal first period, or a percentage off for a fixed time all end. The cost of the stay is the offer for as long as it lasts, then the standard rate for the rest. A quote that will not state the standard rate is not ready to compare.

Write down when the offer ends in weeks or months, matching the words on the page, and whether it covers only the storage rate. On this site we assume a percentage comes off the storage price and not off protection or the padlock, because that is the usual shape. If your offer is more generous than that, enter the lower figures you will actually be charged. Do not rely on the tool to be kinder than the contract.

Short stays make offers look larger than they are. If you only needed the discounted weeks, the offer is the product. If you needed four months and the offer covers one, three months are at the other number. People moving house often sit in the second group. The stay length is the input that stops the advert doing the thinking.

Minimum term and notice

A low rate with a long minimum term can outlast the reason you stored anything. A house purchase that completes early, a student who decides to go home after all, a shop refit that finishes in a fortnight: the unit does not empty itself from the bill. Ask how many weeks you must pay even if you leave sooner, and how much notice you must give when you do leave.

Notice is a cost when it starts only on a billing date, or when it is longer than the gap you have. Ask what “a week’s notice” is attached to. Ask whether you can empty the unit on the last day of the notice, and whether access that day is inside opening hours. None of this is in the calculator, on purpose. A tool that guessed your notice period would be inventing a contract.

Protection, insurance, and the policy you already have

You will usually be asked to cover the goods. The routes are not interchangeable. The store may sell a protection plan, billed with the unit. You may already have a contents policy. You may need to buy a specific storage policy. A protection plan is not automatically an insurance contract in the everyday sense of the word, and a contents policy does not automatically follow the boxes into a warehouse.

Read the exclusion for goods kept in storage, any limit per item, and whether you must tell the insurer the goods have moved. Bikes, laptops and jewellery are the things that surprise people, either because a single-item limit is lower than the replacement cost or because the policy expects them to be at the home address. This guide will not quote a limit. Limits differ. The document in front of you is the one that pays, or does not.

If you take the store’s plan, enter it in the calculator in the same billing period as the storage price. If your own policy covers the stay and the store will accept proof, leave that field blank so you do not double-count. Ask what proof they want, and whether they want it before you get a code for the door.

Padlocks, admin fees and other one-offs

A store that has been broken into once starts caring about locks. Many will sell you a lock, or require a certified one, and refuse a luggage padlock. Budget for the lock they will actually accept. On a one-month stay it is a visible share of the bill. On a one-year stay it is noise. The calculator keeps it as a one-off so the length of stay does that weighting for you.

Admin fees cover whatever the store says they cover: opening the account, printing a contract, replacing a lost code. Ask if the fee comes back when you extend, or only when you are a new customer. Ask if a failed direct debit creates a second fee. That second fee is a late-payment cost, and it belongs in your decision only if you know the number. Do not let a website invent one.

Deposits

A deposit is money you hand over and hope to see again. Many contracts refund it when the unit is clear, the lock is off, and the account is settled. Some set out deductions for cleaning, damage, or unpaid rent. Read that list before you treat the deposit as a rounding error, and before you treat it as gone. The calculator shows the deposit and keeps it out of the total used to declare a winner. You still need the cash on day one. “Cheaper over six months” and “can I pay the deposit this week” are different questions.

Access, and the costs that are not on the invoice

A cheap unit an hour away, with no late access and a flight of stairs, is not cheap on moving day. Van hire, parking at the store, and a second trip because the lift was booked out are all real. They are also personal. This site does not add a generic travel cost. It does tell you to ask the access hours, including Sundays and bank holidays, and whether the loading bay needs a booking. If you are storing between completions, those hours decide whether the unit is useful on the only day the removers are free. The moving guide stays with that problem.

VAT and price rises

Facilities for the self-storage of goods have been standard-rated for VAT since 1 October 2012. The standard rate at the time of writing is 20%. Narrow exceptions exist, and this is not tax advice. What you need on the day is a yes or no: is VAT in this figure? Compare two prices only when they answer that the same way. A business quote excluding VAT will look falsely low next to a household quote that includes it.

Also ask how long the rate is held. A promotion that can change on 30 days’ notice is a different product from a rate fixed for the minimum term. If the store can move the price, the calculator’s total is a picture of the quote you were given, not a picture of month nine. Say that to yourself before you forward the result to anyone else.

Prohibited goods and the cost of being turned away

Every store publishes a list of what it will not take. Fuels, gas bottles, paint and perishable food are commonly on it. Plants die. Stolen goods are not a funny grey area. The list you must obey is the one for that building, not a list summarised by a guide. Being refused at the door, with a van already hired, is an expensive way to discover a paragraph you skipped.

A checklist before you pay

  1. Size in square feet, and the ceiling height.
  2. Rate, and whether it is weekly, four-weekly or monthly.
  3. The standard rate, and the date the offer ends.
  4. Protection: whose policy, what it costs per period, what proof is required.
  5. Admin fee, padlock, deposit, and whether the deposit is refundable.
  6. Minimum term and notice period.
  7. Access hours on the day you will actually move.
  8. VAT included or not.
  9. How long this rate is held.

Put lines 2 to 5 into the calculator for the stay you expect, not the stay the discount assumes. Keep lines 6 to 9 in a note beside the result. If two quotes are close after that, choose the one you can get into on moving day. The arithmetic will not rescue a unit that is shut.

A little more clarity

Good questions.
Straight answers.

Is a deposit a cost?

Treat it as money you may not get back automatically. Many stores refund it when you leave, the unit is clear and the account is paid. Read what they can keep it for. Do not add it to the price as if it were gone, and do not ignore it when you plan the cash you need.

Will my home insurance cover a storage unit?

You have to read your policy. Some contents policies restrict cover once goods are in storage, cap a single item, or expect you to tell the insurer. A store may also ask for proof of cover, or sell its own protection plan. Those are not the same thing.

What is an admin fee for?

Stores use the name for different things: opening the account, sending paperwork, or replacing a lost lock. Ask what it covers and whether it is charged again if you extend. If it is one-off, it matters more on a short stay than on a long one.
