If you’re pricing up a storage unit, the cost depends on three things: size, hire length, and where you need delivery. In the UK, door-to-door portable storage units typically start from around £20–£35 per week for a small unit, rising to £70–£100+ per week for a full-size 40ft container. Traditional self-storage warehouses tend to work on a monthly billing cycle, starting from around £30–£50 per month for the smallest locker-style spaces, but those costs rise quickly once you account for insurance, access and admin fees.
This guide covers what you can expect to pay for a UK storage unit in 2025, what drives the price up or down, and how to make sure you’re not paying for more space than you need.
What affects the cost of a storage unit?
Several variables feed into the final price:
- Unit size — the biggest single cost driver. A 7ft × 7ft unit suited to a kitchen clearout costs significantly less per week than a 20ft or 40ft unit capable of clearing a full house.
- Hire duration — longer-term hires generally attract a lower effective weekly rate. Providers including Door To Store offer flexible rolling terms with no fixed minimum period.
- Location and delivery distance — delivery to central London carries a higher surcharge than a standard delivery zone. The further from the depot, the higher the delivery and collection fee.
- Type of storage — a door-to-door portable unit (delivered to your driveway) and a traditional self-storage warehouse unit work very differently in terms of access, convenience, and total cost.
- Access requirements — narrow roads, low bridges, or restricted sites may require a site survey before a delivery can be confirmed.
UK storage unit costs — what to expect
As a guide, UK door-to-door portable storage unit hire typically breaks down as follows:
| Unit size | Typical weekly rate | Typical monthly rate |
|---|---|---|
| 7ft × 7ft (small) | £20–£35 | £80–£140 |
| 20ft (medium) | £40–£65 | £160–£260 |
| 40ft (large) | £70–£100+ | £280–£400+ |
Delivery and collection fees are typically charged separately and vary by location. Always ask for a total cost quote — including delivery, collection, and any admin charges — so you’re comparing like for like between providers.
For context, traditional self-storage warehouse facilities tend to advertise lower headline weekly rates, but the total cost of use (transport, access hours, insurance requirements, admin fees) often closes the gap or exceeds a door-to-door service for anything beyond a short-term store.
How much storage do you need?
Getting the size right means you’re not paying for space you won’t fill. As a rough guide:
- 7ft × 7ft — one or two rooms of furniture, a standard kitchen clearout, or seasonal business stock. Ideal for renovations affecting a single room or a short-term home declutter.
- 20ft — contents of a 2–3 bedroom house, large home renovation projects, or medium-volume business inventory. The most commonly hired size for full-room clearances and moves.
- 40ft — full house contents, construction materials, business inventory, or event equipment. Suited to large commercial hires, house clearances, and long-duration construction site storage.
If you’re unsure which size is right for your situation, it’s worth calling ahead and describing what you need to store. Door To Store can advise on sizing at no obligation.
Door-to-door storage — how it works and why it can cost less
With a door-to-door storage service, the unit comes to you. You agree a delivery date, the unit arrives at your address, and you load it at your own pace — no van hire, no time pressure, no trips to a warehouse. When you need collection, you book a date and the unit is removed.
The real cost saving over traditional self-storage is in the hidden costs you avoid. No van hire or removals lorry to get things to a facility. No restrictions on when you can access your belongings. No per-visit parking charges or lift access fees. For anyone storing for more than a few weeks, the convenience saving typically outweighs any marginal difference in the weekly hire rate.
How to keep your storage costs down
Declutter before you book. The less you store, the smaller the unit you need. A thorough sort before your delivery date can often drop you an entire size tier — which means a meaningfully lower weekly rate for the duration of your hire.
Be clear on your end date. Open-ended rolling hires are convenient, but if you have a fixed project timeline — a renovation finishing in six weeks, a house move completing in a month — factor that into your hire term from the start rather than letting it run indefinitely.
Book ahead where possible. Last-minute delivery requests may carry a premium for urgent slots. Planning ahead gives you flexibility on delivery dates and often the best rate.
Get a total cost quote. Weekly hire rate headlines can be misleading. Always ask for a figure that includes delivery, collection, and any additional fees so you can make a fair comparison between providers.
