Automated self storage: how unstaffed sites work

Automated self storage, sometimes called self storage automation, is not the warehouse kind of automated storage, where machines fetch pallets from racking. This guide is about ordinary storage units, containers and yards that customers visit themselves, and the same set-up can run a staffed site, a hybrid one or a site with nobody on it.

Booking, signing and collecting the licence fee can all be done online. What decides whether an unstaffed site works is everything physical around it: how customers get in, what happens when something goes wrong, and which duties in fire safety, health and safety, data protection and planning still apply when nobody is there. This guide takes them in that order and ends with what StoreBay’s self storage management software does today and what it does not.

Staffed, hybrid or unstaffed

“Automated” covers a range, and the three set-ups this guide uses differ in who is on site and when.

• Staffed. A manager or team is on site in opening hours and customers can move in at the counter. Software still handles prices, payments and reminders.
• Hybrid. Customers can do everything online and use the site outside staffed hours, and staff are on site for set hours or on call.
• Unstaffed. Nobody is on site. Customers book, sign, pay and get in without meeting anyone, and a remote team or an occasional visit deals with problems.

UK operators are moving this way. The SSA UK and Cushman & Wakefield annual report, which covers 2025, puts average staffing at 2.6 staff per store, a record low and down from 3.0 in 2023, and counts 16.2% of stores as unmanned, a term it does not define. For container storage, the trade body CSTA reports that unmanned or sometimes-manned sites made up 73% of the operating models reported for 2025.

Opinion is divided. The report found 44.1% of people willing to use a fully unmanned store against 39.4% unwilling, without saying which of its three surveys the figure comes from. It reads the narrow margin as a sign that a significant part of the market still values human interaction, particularly when choosing a unit size and understanding the terms. An unstaffed site has to answer those questions another way: clear guidance on sizes, terms that read well on a phone, and a phone number that someone answers.

One unstaffed move-in, start to finish

The steps below are the same on a staffed site. The difference is that on an unstaffed site nothing waits for a person, so each step has to work without help.

We think two steps carry the most risk. Access has to work the first time, because the customer is standing at a gate with a van. And the missed payment at the end has to be handled by a rule, because no one walking the site will spot it.

A booking a consumer makes online also raises questions about information and cancellation. Our guide to the cooling-off period for self storage booked online sets out what the Consumer Contracts Regulations say and what the sources leave open.

The five systems an unstaffed site needs

1. Booking with the price shown. The customer picks a size and a date and sees what they will pay. For consumers that means the total, including VAT and every fee or charge they will necessarily incur if they book; our DMCC Act guide sets out the rules. The website design guide covers the pages themselves.
2. A licence signed online. In legal proceedings an electronic signature is admissible in evidence on questions about whether the signed communication is authentic and whether it has been altered (Electronic Communications Act 2000, section 7), and the UK version of the eIDAS Regulation says it cannot be denied legal effect solely because it is electronic (article 25). The Law Commission’s conclusion for England and Wales, which the Government agreed with in 2020, is that an electronic signature can be used to sign a document if the signer intends to authenticate it and any formalities are met; it lists a typed name in an email and clicking an “I accept” tick box among the forms courts have accepted where a statute requires a signature. We have not read the Scottish rules on electronic signatures, which are separate.
3. Payment that collects itself. Recurring payment by Bacs Direct Debit or card on file, with dunning rules that remind, retry and then escalate, and a late fee only if the agreement allows one. Check which of those timings you can set yourself.
4. Access that follows the account. A gate, door or lock system that issues a code or credential at move-in and can restrict access when an account is overdue; overlocking explains how that works on a padlocked site. The hardware comes from an access-control supplier, and the software either connects to it or leaves staff to do the work by hand. Ask what each device does when it loses power or its connection, because, in England and Wales, emergency doors must still open (Fire Safety Order, article 14).
5. Eyes and a voice on the site. Cameras, alarms, an intercom or a phone number that gets answered, and a named person who is alerted. Monitored CCTV is already the norm: 90.8% of UK stores use it, according to the SSA UK annual industry report 2026 (2025 data).

Where unstaffed sites go wrong

• Access that fails at the wrong moment. A power cut, a flat battery or a lost mobile signal should not strand a customer at a closed gate or leave a door that will not open from inside. Find out what each device does when it loses power or its connection, and keep a way in that does not depend on it.
• A problem nobody sees. A door left open, a leak, an alarm. An alert that goes to a person who may not answer is not monitoring. Decide who is told, in what order, and test the chain.
• Slow chasing. On an empty site nobody notices an overdue account by walking past, so the reminders, the late fee and the overlock have to be set as rules, not left to memory.
• A journey that breaks on a phone. Some customers will book on a phone with a poor signal. Walk through your own booking, signing and payment on a cheap handset and on mobile data, and read your first support requests to see where people stall.
• Hours you were never allowed. A planning permission can cap the hours a site may be open, as the next section shows. Check yours before you advertise round-the-clock access.
• Treating “no staff” as “no duties”. The next section covers what still applies.

What UK law still asks of an empty site

None of the fire safety, health and safety, data protection or planning sources we read on 9 October 2026 says that a storage site must be staffed. One duty is unresolved for a site with nobody on it: the Order requires competent people to be nominated for evacuation, and the sources we read do not say how an empty site meets that. The other duties apply whether anyone is there or not, and some are harder to meet when nobody is. What follows summarises those sources. It is not advice, and it has not been checked by a solicitor or a fire risk assessor.

Does fire safety law apply to a site with nobody on it?

In England and Wales the Regulatory Reform (Fire Safety) Order 2005 applies to any premises other than those it lists, and every site has a “responsible person”. Where the site is a workplace that is the employer, if the workplace is to any extent under the employer’s control; otherwise it is whoever controls the premises in connection with a business, or failing that the owner. The Home Office guide says premises that are not a workplace still have one. The responsible person must assess the fire risk and, since 1 October 2023, record the assessment and the fire safety arrangements in full in every case. Where necessary they must provide detectors, alarms and fire-fighting equipment, and emergency doors must not be locked or fastened so that they cannot be opened easily and immediately in an emergency. The Home Office guide, which applies to England, adds that fire detectors might be needed to give a warning if a fire occurs in unoccupied areas, from which it could spread to affect means of escape from occupied areas.

Evacuation is where an empty site is hardest. The Order requires a sufficient number of competent people to be nominated to carry out the evacuation procedures, with no “where necessary” qualifier, while the Home Office guidance describes nominating people and calling the fire service for “staffed premises”. How an unstaffed site meets that duty is a question for a fire risk assessor. Scotland and Northern Ireland have their own laws, the Fire (Scotland) Act 2005 and the Fire and Rescue Services (Northern Ireland) Order 2006. They put the duties on employers and on anyone with control of the premises “to any extent”, and they require a written record only with five or more employees, a licence or registration, or an alterations notice.

Can a manager or contractor visit an empty site alone?

A manager or contractor who goes to an empty site alone is a lone worker. The Health and Safety Executive (HSE) says working alone will often be safe, but that the law requires the risks to be dealt with before people do it. A separate assessment is not required: include lone workers in the general risk assessment, train, supervise and monitor them, keep in touch, respond to incidents, and test the systems used to reach them regularly. HSE’s examples of work that needs a second person include confined spaces, work near exposed live conductors, diving, vehicles carrying explosives and fumigation. The assessment must be written down where an employer has five or more employees. In Northern Ireland the regulator is HSENI, which also says working alone is legal with a risk assessment and suitable controls.

Do cameras on an empty site mean paying the data protection fee?

Yes, unless the business is exempt or already pays it. Cameras that record identifiable people are covered by UK data protection law. The regulator’s guidance says a business that records CCTV to prevent crime must pay the data protection fee unless it is exempt or already pays it. The fee is £52, £78 or £3,763 a year depending on size, with £5 off if paid by Direct Debit. People must be told they are being recorded, usually with signs that say who runs the system, why and who to contact, and the regulator says a data protection impact assessment applies in most cases. The law sets no fixed period for keeping footage: the purpose decides it. A person can ask for a copy of footage of themselves, and the operator must provide it without undue delay and within one month, counted from the latest of the request, the identity details the operator asked for and any fee it may charge. If the requests are complex or numerous, the operator can add two months by telling the person why before the first month ends. Days spent waiting for details the operator reasonably needs to find the footage, such as the date, time and location, do not count. Cameras should cover the space you need and avoid private land and people who are not visiting the site. The regulator is now the Information Commission, which replaced the Information Commissioner on 30 September 2026; on 9 October 2026 its website and guidance still said ICO, and its CCTV guidance was under review.

Can planning conditions limit the hours a self storage site is open?

Yes. A planning permission can set the hours a site may be open to customers. In an appeal decided on 5 October 2026 (6009712), an inspector allowed a self-storage building in Greenwich to open to the public from 07:00 rather than 08:00 on Monday to Saturday, closing at 21:00 as before, and left Sundays and public holidays at 08:00 to 20:00. The inspector found limited evidence that the earlier opening would cause unacceptable harm to neighbours’ living conditions, and noted that the council’s environmental health officers had not objected. In North Hertfordshire (application 22/01810/FP), a 20-container site proposed with 24-hour access, no staff on site and remote management was granted by the planning committee in February 2023 for use between 07.00 and 20.00 only, after the environmental health officer noted that no noise assessment had been submitted. National planning policy says conditions should only be attached where they are necessary, relevant, sufficiently precise and reasonable in all other respects (Policy DM6 of the National Planning Policy Framework for England). These examples and that policy are English: we have not read planning rules in Scotland, Wales or Northern Ireland. Read your permission before you promise round-the-clock access, and see our guide to planning permission for storage containers.

Questions to put to a fire risk assessor and a solicitor:

• How are the Order’s evacuation arrangements met when nobody is on site?
• Is automatic fire detection needed in unoccupied areas, and where do the alarms go?
• How do automated gates and doors release in an emergency and in a power cut?
• Does a customer who holds a licence for a unit have “control” of it for the purposes of fire safety law?
• Does your planning permission limit your opening hours?

How StoreBay fits today

StoreBay handles online booking, online signing, and payment collection with reminders. For the fourth system it supplies the rule and the notices, not the gate or the lock. Today it does these things:

• Customers see live availability and prices for each size, choose a size and a move-in date, and StoreBay holds a free unit of that size.
• They sign the licence online as part of the booking, then pay by card or set up a Direct Debit. A Direct Debit is collected afterwards, on a date the customer is emailed first.
• When a payment fails, StoreBay follows the reminder schedule you set. By default that is emails on days 2, 5, 8 and 14 and a £15 late fee on day 8, and you can change the days or the fee, or switch the fee off.
• Your rule decides when an overdue unit is overlocked: by default planned 14 days after a missed payment and applied after 21, which you can change or switch off. StoreBay tells your staff which unit to padlock and, once the customer has paid, tells them to take the padlock off.

Connections to the gates and locks you run are coming soon. Until then an overlock is a notice to your staff, not an automatic lock, so a site with nobody on it still needs its gate, lock and camera systems from other suppliers and a person to act on the notices. StoreBay never sells or ships locks, gates or readers.
