Hong Kong mini storage splits into two models. Self storage means you rent a unit, hold the lock, and walk in whenever the branch is open. Door-to-door (valet) storage means the operator brings boxes to you, takes them to a warehouse you cannot enter, and brings individual boxes back on request. The headline prices look similar, but the two products are not directly comparable — the fees that decide value live in different places. One number floating around needs correcting too: the "HK$150-plus per retrieval" figure is not a published rate at any Hong Kong operator. As of early August 2026 the published per-trip retrieval charges run about HK$80–HK$90 for up to six boxes — Boxful HK$80 minimum, Spacebox HK$90, U SPACE HK$90 — or HK$18–HK$20 per box.
Self storage vs door-to-door at a glance
| Dimension | Self storage | Door-to-door / valet |
|---|---|---|
| Access model | You hold the lock and visit the unit during branch hours | Operator retrieves boxes from a warehouse you can't enter, on appointment |
| Best for | Frequent access, bulky or odd-shaped items, business stock you rotate | Sealed boxes of seasonal or archived items you rarely need |
| Cost to check | Rent, deposit (1–2 months), admin/lock/card fee, insurance, transport to branch | Per-box rent, retrieval trips at HK$80–90 after free allowances, minimum box count, lead time |
| Typical catch | Headline "from" rent excludes the HK$100 admin fee, deposit and insurance | Low per-box rate covers storage only; each extra trip after the free round-trip is HK$80–90 |
Read the table as a decision rule, not a verdict. If you answered 'frequent access' or 'odd-shaped items', self storage wins almost regardless of price, because door-to-door operators charge per trip and many refuse oversized items. If you answered 'sealed boxes I will not touch for a year', door-to-door can win — but only after you add the minimum box count and the retrieval trips you will actually make.
What door-to-door boxes actually cost in 2026
| Operator | Per box / month | Box size & weight | Retrieval & delivery | Minimums |
|---|---|---|---|---|
| U SPACE | HK$45 (headline "from HK$42") | 60 × 40 × 32 cm, max 23 kg (about 40 tees) | Free first delivery; 1 free round-trip every 2 months; extra trips HK$18/box, min HK$90/trip | HK$180/month spend (about 4 boxes); no deposit |
| Boxful | HK$35 standard (document HK$29, bulky HK$69–89) | Standard box via Boxful's box supplier | First pickup free; retrieval HK$20/box, min HK$80/trip | HK$175/month min charge; 3-month minimum term |
| Spacebox | HK$49 standard (document HK$29, big box HK$69) | Standard 60 × 40 × 31 cm, max 23 kg | Free first check-in; 1 free round-trip every 2 months; extra or final trips HK$90 for up to 6 boxes, HK$15 each extra | HK$180/month min; long-term plan min 6 months (3-month plan available) |
Note what the per-box rate does not include: it covers storage only. The empty-box drop-off, the first collection and one round-trip every couple of months are usually free, but every retrieval beyond the allowance is billed per trip. The Consumer Council's 2020 study measured door-to-door storage at HK$39–HK$49 per standard box a month, so today's published HK$35–HK$49 sits in the same band it found four years ago. For a full method of adding up all the fees, see our mini-storage costs and fees guide.
What self storage costs for the same stuff
You never rent a self-storage unit just for six boxes — you rent it because you also have furniture, a bike or stock. But here are real published prices for the smallest units, as of early August 2026, so you can anchor the comparison:
- Storefriendly 8 sq ft: HK$525/month in Tuen Mun, HK$592 in Kwai Chung, HK$1,160 in Sai Wan — roughly HK$66 vs HK$145 per sq ft depending on district.
- RedBox Kwai Chung 8 sq ft: HK$570/month, plus a one-off HK$100 admin fee and insurance from HK$28/month; the Summer Flash half-price promo (to 15 August 2026) takes it to about HK$285.
- 24 STORAGE Kwai Chung: about HK$310/month average — but only on the prepay 6 months + 2 free deal, so it is an up-front bill, not a monthly one.
- U SPACE self storage: 6 sq ft from HK$449/month (average from HK$399); access is free for the first entry, then HK$69 per access unless you book ahead by 3pm the working day before.
- Consumer Council 2020 baseline: 12 sq ft units ran HK$480–HK$1,709 a month and 16 sq ft units HK$696–HK$3,038, with deposits typically 1–2 months' rent.
Worked example: 6 boxes for 12 months
Say you are between leases, you have six standard boxes of clothes and documents you will barely touch for a year, and you expect to ask for things back about twice. Here is the 12-month bill at current published rates (prices verified early August 2026):
| Option | Storage, 12 months | Retrieval & delivery | Approx total |
|---|---|---|---|
| U SPACE boxes, 6 × HK$45 | HK$3,240 | Both retrievals inside the free round-trip allowance; extra trips HK$90 each | ≈ HK$3,240 |
| Boxful boxes, 6 × HK$35 | HK$2,520 | First pickup free; final retrieval 6 × HK$20 = HK$120, one subsequent retrieval HK$120 | ≈ HK$2,760 |
| Spacebox boxes, 6 × HK$49 | HK$3,528 | Retrievals free; HK$90 final check-out (up to 6 boxes) | ≈ HK$3,618 |
| Storefriendly 8 sq ft unit | HK$592 × 12 = HK$7,104 | Unlimited walk-in access, HK$0 per visit — but you travel to Kwai Chung | ≈ HK$7,104 (plus deposit & travel) |
So for six sealed boxes with light retrieval, door-to-door runs about HK$2,760–HK$3,618 a year — roughly half the HK$7,104 of the cheapest comparable unit, and close to the Consumer Council's measured HK$2,740–HK$3,810 for its five-box, one-year example. But now flip the retrieval count: if you asked for a box back every month, Boxful's trips alone add 12 × HK$120 = HK$1,440, taking you to about HK$3,960 — and the self-storage unit, for the same money, also holds your furniture and lets you in at any hour. Door-to-door wins on price and convenience only as long as you stay a set-and-forget customer.
When each model wins
Self storage wins when access is part of the value. If you are rotating business stock, retrieving seasonal gear, or doing renovation in stages, walking into your own unit with no retrieval fee and no waiting beats any per-box saving. It also wins for items door-to-door operators will not accept — oversized furniture, fragile valuables, or anything needing climate control you want to verify in person. Door-to-door wins when access is rare and items are uniform: archived documents, winter clothes in summer, the contents of a flat you are between leases on. Both Boxful and U SPACE run door-to-door services alongside self-storage in Hong Kong, so the models are not always a strict either/or. For the same choice framed as two brands, see our Cube Self Storage vs U SPACE comparison; for picking a provider by your priority, see our best mini-storage 2026 hub.
Which is better for moving house?
Neither model is designed for moving house, but people reach for both during a move. Use self storage for items you want to keep and access during the transition, and a dedicated moving service for the move itself. Door-to-door storage marketed as 'moving plus storage' bundles a van and boxes, but check whether the van is a fixed fee or charged by the hour — U SPACE, for example, bills tunnel tolls and parking to you and adds a district-based delivery surcharge — and whether later retrieval is included or billed per trip. If you are between leases for a few weeks, door-to-door works for boxes you will not need until you settle; self storage works better for things you will need during the gap. For renovation timelines and sizing, see our renovation storage guide.
Insurance, access and the fine print
- Insurance differs sharply. U SPACE's mini-box service includes no insurance at all. Boxful covers up to HK$10,000 per storage plan. Spacebox caps liability at HK$1,000 per item and HK$10,000 per customer — the same per-item cap the Consumer Council found typical across self-storage. One item over HK$1,000 can exceed the cover. See our mini-storage insurance guide for the gaps.
- Access is appointment-based, not walk-in. U SPACE needs booking one working day ahead by 3pm; Spacebox can do next-day delivery if you book before 3pm the previous working day, Monday to Saturday; Boxful returns by appointment. Self storage is walk-in during branch hours — U SPACE's own self-storage charges HK$69 per access after the first free entry unless you book.
- Weight and size caps. Spacebox items must weigh at most 25 kg with length + width + height within 180 cm, and its standard box takes up to 23 kg. U SPACE boxes are 60 × 40 × 32 cm at 23 kg, and its self-storage lockers cap at 400 kg.
- Surcharges hide in the delivery leg. U SPACE bills tunnel tolls and parking to the customer and adds a district-based surcharge; Spacebox adds a stair fee for walk-ups; Boxful charges HK$15 for a document box and HK$150 for a wardrobe box if you buy them.
- Minimum box counts are real. U SPACE's HK$180/month minimum spend works out to four boxes, Spacebox's to four at its standard rate, and Boxful's HK$175 minimum to five standard boxes — a single box on its own is not an option.
Frequently asked questions
Is door-to-door storage cheaper than self storage?
For sealed boxes you rarely open, yes — at 2026 published rates, six standard boxes for 12 months come to roughly HK$2,760–HK$3,618 with two retrievals, versus HK$6,300–HK$7,100 for the smallest self-storage units. But the per-box rate covers storage only: after the free round-trip allowance (one every two months at U SPACE and Spacebox; none at Boxful), each retrieval costs HK$80–90 per trip or HK$18–20 per box. If you retrieve often, or store anything bigger than a box, the unit wins on total cost.
Can I access my items anytime with door-to-door storage?
No. Door-to-door storage is appointment-based: U SPACE requires booking one working day ahead by 3pm, Spacebox offers next-day delivery if you book before 3pm the previous working day (Mon–Sat), and Boxful returns by appointment. There is no walk-in access to the warehouse. If you need unaccompanied, on-demand access — and you can accept a per-access fee at some self-storage branches — choose self storage instead.
What does each retrieval actually cost?
In 2026 the published per-trip charges are HK$80–HK$90 for up to six boxes: Boxful charges HK$20 per box with an HK$80 trip minimum, U SPACE HK$18 per box with an HK$90 minimum, and Spacebox HK$90 flat for up to six boxes plus HK$15 per extra box. These apply after the free allowances — U SPACE and Spacebox each include one free round-trip every two months. The often-cited "HK$150-plus per retrieval" figure is not a published rate at any Hong Kong operator.
Does the storage company's insurance cover my belongings with door-to-door storage?
Only partially, and with low per-item limits. U SPACE's mini-box service includes no insurance. Boxful covers up to HK$10,000 per storage plan. Spacebox caps liability at HK$1,000 per item and HK$10,000 per customer — a single item over HK$1,000 can exceed the cover. For valuables, take out your own contents insurance and check the per-item limit and exclusions before booking.
