Celtic Self Storage
"How much does self storage cost?" is one of the most common questions people in Warsaw type into a search engine when they start looking for a storage unit. And for good reason — prices can vary wildly depending on location, operator, and unit size. In this guide, we break down every factor that influences self storage pricing in the capital so you can make an informed decision.
What affects the price of self storage?
Before you start comparing quotes, it helps to understand the variables behind the numbers. It is not just about square metres — several other factors play a role.
1. Unit size
This one is obvious but worth spelling out. Storage units typically range from 1 m² to more than 20 m². Larger units cost more per month in absolute terms, but less per square metre — so you get better value as you scale up.
Common sizes and what they hold:
| Size | Capacity | Best for |
|---|---|---|
| 1–2 m² | 5–10 boxes | Documents, seasonal clothes, sports gear |
| 3–5 m² | Contents of a studio flat | Students, people mid-move |
| 6–10 m² | Contents of a 2–3 bedroom flat | Families, businesses with archives |
| 11–15 m² | Entire apartment | Major renovation, long-term storage |
| 16–20+ m² | Large flat or house | Companies, e-commerce, wholesale |
2. Facility location
Storage in central Warsaw (Srodmiescie, Wola) can cost two to three times more than on the outskirts. Ironically, reaching a suburban facility is often faster because you avoid traffic jams and the hunt for parking.
3. Rental period
Most operators, including Celtic Self Storage, offer lower rates for longer commitments. Signing up for six or twelve months instead of going month-to-month typically saves you 10–20 percent.
4. Floor level and access type
Ground-floor units with drive-in access are the most convenient, but they can carry a small premium. Upper-floor units (in facilities that have a freight elevator) are sometimes cheaper.
5. Climate control
Not every facility offers temperature-controlled units. If you are storing electronics, important documents, or wooden furniture, paying a little extra for a climate-controlled space is a smart move.

Average price per square metre
| Location | Price per m²/month | Notes |
|---|---|---|
| City centre (Srodmiescie, Wola) | 80–120 PLN | Most expensive, difficult access |
| Inner suburbs (Mokotow, Bielany) | 55–85 PLN | Balance of price and convenience |

Typical monthly costs by unit size
To make these numbers more tangible, here is what you can expect to pay for popular unit sizes:

How Celtic compares to other Warsaw operators
Here is a side-by-side look at the cost of renting a 5 m² unit for six months:
| Operator | Price/month (5 m²) | Deposit | Parking | 24/7 access |
|---|---|---|---|---|
| Celtic Self Storage | ~300–350 PLN | None | Free | Yes |
| Operator A (city centre) | ~500–600 PLN | 1 month | Paid | Yes |
| Operator B (suburbs) | ~350–450 PLN | None | Free | Limited |
| Operator C (city centre) | ~450–550 PLN | 1 month | None | Yes |
Over six months, choosing Celtic can save you between 600 and 1,800 PLN compared with city-centre operators.
Hidden costs in self storage — what to watch out for
Not every price list tells the full story. Before you sign a contract, check for these potential extras:
1. Refundable deposit
Many operators require a deposit equal to one or two months' rent. That money is tied up for the entire rental period. Celtic does not charge a deposit.
2. Administration fee
A one-off charge for "opening an account" or "preparing the unit" — anywhere from 50 to 200 PLN. We do not charge one.
3. Insurance surcharge
Some facilities require you to buy additional insurance (30–80 PLN/month). At Celtic, basic insurance is included in the price.
4. Access fee
Occasionally, free access is limited to office hours (e.g. 8 a.m. to 6 p.m.). Evening or weekend visits cost extra. At Celtic, 24/7 access comes at no additional charge.
5. Freight elevator fee
In multi-storey facilities, using the elevator can be a paid service. At Celtic, all units have drive-in access on a single level.
6. Minimum rental period
Some operators insist on a three- or six-month minimum. At Celtic, the minimum period is one month.
7 proven ways to save on self storage
1. Choose the right size
Do not overpay for a unit you will never fill. Use our unit finder to find the best fit.
2. Commit to a longer period
If you know you will need storage for several months, a longer contract brings a real discount.
3. Pack efficiently
Good packing lets you fit more into a smaller unit. Disassemble furniture, fill every gap inside wardrobes and drawers, and stack boxes to the ceiling.
4. Pick a suburban location
A unit in Lomianki or Piaseczno costs significantly less than one in the city centre, and the drive from Bielany or Mokotow takes just 10–15 minutes.
5. Declutter first
Before packing, do a ruthless sort. Every item you do not store is space (and money) saved.
6. Avoid operators that charge a deposit
A deposit equal to one month's rent is an extra cost on day one. Choose a no-deposit facility — like Celtic.
7. Check what is included
A cheap headline price can turn expensive once insurance, parking, and access fees are added on top.
Self storage vs other storage options — cost comparison
Self storage vs basement
| Criterion | Self storage | Basement |
|---|---|---|
| Security | CCTV, PIN, alarm | Usually none |
| Humidity | Controlled | High, risk of mould |
| Access | 24/7, drive-in | Stairs, poor lighting |
| Flexibility | Change size any time | Fixed |
| Cost | From 169 PLN/month | "Free" (but potential losses) |
Self storage vs garage
Renting a garage in Warsaw runs 300–800 PLN/month but offers no climate control, no monitored security, and no flexibility to resize.
Self storage vs renting a flat for storage
The cheapest studios available as makeshift warehouses cost 1,500–2,500 PLN/month plus utilities. For the same money, you could rent a 15–20 m² unit at Celtic — a far cheaper and more secure solution.
When does self storage make financial sense?
Self storage is the best option when you are:
- Renovating — you need storage for one to three months
- Moving — temporary storage between addresses
- Running a business — archives, e-commerce stock, tools
- Swapping seasons — tires, skis, garden furniture
- Running out of space — and not ready to move to a bigger flat
How to book a unit at Celtic Self Storage
The process is simple:
- Choose a location — Lomianki (north) or Piaseczno (south)
- Find the right unit — use the unit finder
- Check the pricing — transparent rates, no hidden fees
- Reserve your unit — online or by phone
- Move in — even on the same day
