Most UK households pay somewhere between roughly £95 and £150 a month for a 50 square foot unit, the size that takes a one-bedroom flat, and between £190 and £250 for 100 square feet, which is about a single garage and holds a three-bedroom house. A 25 square foot unit runs about £42 to £50. London sits well above all of them.
Two things distort those figures for most people. The first is that the price per square foot falls as the unit gets bigger, so the small unit that looks cheap is the most expensive space you can buy. The second is that the first bill is almost always higher than the quoted rate, because insurance, a padlock and sometimes an admin fee land on it.
Quick answer: Budget £95 to £150 a month for a 50 square foot unit holding a one-bedroom flat, and £190 to £250 for 100 square feet holding a three-bedroom house. London runs substantially higher. Introductory offers of half price for the first eight weeks are common across the sector and revert automatically. These are indicative market rates as at August 2026, drawn from published operator pricing and industry cost guides rather than EcoGreen Movers quotes. Checkatrade’s storage cost guide gives a comparable breakdown by unit size.

Monthly cost by unit size
| Unit size | Indicative monthly range | Roughly holds | Cost per sq ft |
|---|---|---|---|
| 9 sq ft locker | £18 to £30 | 10 to 15 archive boxes | Highest per foot |
| 25 sq ft | £42 to £50 | A large garden shed’s worth | High |
| 50 sq ft | £95 to £150 | Contents of a one-bedroom flat | Around the average |
| 75 sq ft | £140 to £200 | A two-bedroom house | Improving |
| 100 sq ft | £190 to £250 | A three-bedroom house, about a single garage | Better value per foot |
| 150 to 200 sq ft | £285 to £380 | A four-bedroom house | Lowest per foot |
Those are indicative UK ranges as at August 2026, taken from published operator pricing and industry cost guides. They are not EcoGreen Movers rates and should be treated as a starting point for comparison rather than a quote.
Why the industry’s own figure is not the price you pay
You will see self storage quoted at a rate per square foot. That number comes from the Self Storage Association UK Annual Industry Report, now in its 19th year and produced with Cushman and Wakefield, which put revenue at £27.40 per square foot excluding VAT in its 2026 edition, down 5.1 percent from £28.87. Crucially that is operator revenue per square foot, not a customer price list. Safestore says plainly on its own storage prices page that these figures do not directly reflect what customers pay.
This distinction matters because the per-square-foot figure gets repeated everywhere as though it were a menu price. It is not. It is what operators earn across their occupied space, averaged over promotional rates, long-stay discounts and premium products alike. Your quote will sit above or below it depending on the site, the floor, the size and the week you walk in.
The direction of travel is worth knowing, though. Revenue per square foot fell year on year, which points to a maturing market with more competition and more room to negotiate than there was a couple of years ago.
Regional variation is wide and consistent. London and the South East sit at the top, while the West Midlands, Wales and Northern England sit well below the national figure, with Scotland between them. Suburban and out-of-town sites are consistently cheaper than city-centre ones, which matters a great deal if you will rarely visit.
Getting the size right is where the real saving sits rather than in shopping between providers. Our guide to storage unit sizes covers how to judge what you actually need before booking.
Why the first bill is bigger than the quote
The advertised rate is the space alone. Contents insurance is required for the whole period, a padlock is your responsibility, and some operators add a one-off admin fee. Comparison service WhatStorage puts insurance alone at roughly £5 to £15 a month on top of the unit rate, and admin fees are charged by some operators and not others.
- Insurance. Required for the whole period, though not necessarily theirs. Many family home contents policies already cover goods stored away from home, which can make the counter product unnecessary. Our guide to self storage insurance covers what to check.
- Padlock. Units are let empty of one. Bring your own or buy at reception.
- Admin or set-up fee. Charged by some operators, not others. Ask directly.
- Part-month billing. Moving in mid-month can mean a pro-rata charge plus a full month up front.
- Deposit. Some sites take a refundable deposit against the unit.
- Access tier. Advertised 24 hour access is sometimes a higher price band than the standard rate.
Ask for the total payable on day one rather than the monthly rate. That single question makes quotes comparable, and it is the number that catches people out when the direct debit is larger than expected.
Introductory offers and when they expire
Half price for the first eight weeks is the standard offer across the sector, advertised openly by operators large and small. It reverts to the full rate automatically, without a prompt, which is why a storage arrangement that felt affordable in month two feels expensive in month four.
Diary the expiry date when you book. Eight weeks from a June move-in runs out in August, and if your storage need has extended you are then paying full rate on a unit you chose on discounted pricing.
Longer commitments are negotiable. Confirming you will need the unit for six months or more is frequently worth asking about a further discount, since occupancy is what the operator is actually selling. Price matching against a competitor within a few miles is also common and rarely advertised.
Check the notice period to leave. Fourteen days is typical, and it means walking out early does not necessarily stop the billing. Rolling monthly terms with short notice are the norm at reputable operators and worth insisting on.

Practical ways to pay less
Upper-floor units are frequently cheaper than ground-floor ones for the same square footage, because ground floor is priced for convenient access. If you will visit rarely, that is a discount for nothing.
Packing properly is the other lever, and it is more powerful than most people expect. Storage is sold by floor area but the units are tall, so stacking to the ceiling rather than spreading across the floor can effectively halve the space you need. Uniform boxes stack squarely; a mixed collection of sizes wastes volume in gaps.
Dismantle furniture rather than storing it assembled. A bed frame flat against a wall takes a fraction of the space it occupies standing, and the same is true of tables and shelving. Keep fixings in a labelled bag taped to the frame.
Declutter before measuring rather than after. Paying £150 a month to store furniture worth £200 is a loss inside two months, and it is a common one because the sorting feels like a job for later. Our guide to decluttering before a move covers where things actually go.
Finally, ask whether collection is included. Providers offering a free move-in van or a collection service remove a cost most people forget to count, and that can be worth more than a small difference in the weekly rate.
What the price includes, and what it does not
A standard self storage rate buys a locked, alarmed unit inside a secured building with access during published hours. Monitored CCTV is close to universal, present at 90.8 percent of facilities according to the Self Storage Association UK 2026 report findings. What the rate does not buy is heating, humidity control, help with loading, or any liability for contents beyond what your insurance covers.
Facilities vary more than the marketing suggests, and the differences are worth checking in person rather than online. A site with a loading bay, trolleys, a goods lift and wide corridors is a fundamentally different experience from one where you carry everything up a narrow staircase, and the cheaper rate is frequently attached to the harder site.
- Access hours. Standard is usually daytime, seven days. Genuine 24 hour access is sometimes a higher tier.
- Loading facilities. Trolleys, a covered bay and a lift make a large difference to how long a move-in takes.
- Drive-up units. Ground floor with vehicle access, more convenient and usually dearer.
- Climate control. A premium product, worth it for instruments, artwork and electronics, unnecessary for most household goods.
- Security. Individually alarmed units, CCTV and PIN entry are standard at reputable sites. Ask what is actually monitored.
- Free move-in van. Offered by some operators and worth real money against a separate hire.
Visit before booking if you can. Photographs flatter storage sites, and the corridor width, the lift capacity and the distance from the loading bay to your unit are the things that decide whether a move-in takes two hours or five.
What a year actually costs
We annualised the monthly rates, because storage is usually taken for a few weeks and kept for far longer, and the twelve-month figure changes how the decision looks.
| Unit size | Indicative annual cost | Equivalent to | Worth it when |
|---|---|---|---|
| 25 sq ft | Around £550 | A weekend away | Genuinely needed items, short gap |
| 50 sq ft | Around £1,300 | A decent second-hand car | A real gap between properties |
| 100 sq ft | Around £2,300 | Replacing most of a room’s contents | Renovation or an extended chain problem |
| 150 sq ft | Around £4,000 | Furnishing a small flat outright | Rarely, unless the contents are high value |
Two findings came out of this. First, at the larger sizes the annual cost approaches the replacement value of ordinary household furniture, which is the point at which storing becomes a decision about sentiment and quality rather than economics. Checkatrade puts a standard 100 square foot unit at roughly £2,310 a year, and most three-bedroom households could not replace their contents for that, so it holds. A 150 square foot unit is a harder case.
Second, storage taken for a defined short gap is cheap and storage taken open-endedly is not. The households that spend the most are those who never set an end date, because there is no natural prompt to review it. Set a date when you book and diary a review a month before it.

Business and student storage priced differently
Two segments sit outside standard household pricing. Business customers are a substantial minority of the market, roughly a quarter of users according to Self Storage Association UK data, and their VAT treatment and access patterns change the economics. Student storage runs on heavily discounted seasonal offers that do not apply the rest of the year.
For a business, the useful comparison is not against another storage site but against the alternatives: a larger unit at your premises, off-site archive storage priced per box, or simply disposing of records that no longer need keeping. Archive storage is considerably cheaper per box than a self storage unit when the contents are purely paper and rarely accessed.
Businesses should also check whether the quoted rate includes VAT, since household and commercial customers are frequently shown different figures, and whether the site permits the kind of access a business needs. Some prohibit stock movements or running any activity from the unit.
Student pricing is a seasonal product built around summer vacation dates, with by-the-box collection services competing directly against units. The arithmetic there works differently because item count rather than floor area drives the price, and it is covered separately in our guide to student self storage.
If you are storing office contents during a relocation, the cost sits inside a larger budget where storage is rarely the biggest line. Our breakdown of office relocation costs sets out where it fits.
When storage is the wrong answer
If your dates line up, do not use storage at all. Every additional handling stage adds cost and risk, and paying to store items for a fortnight because it feels tidier is money for nothing. Storage exists to solve a genuine gap.
Storage companies will not put it that way, so here it is plainly. The comparison worth running is against the alternatives rather than between providers.
A short overlap between properties is often cheaper to solve by paying a few extra days of rent or by negotiating a delayed completion than by moving everything into a unit and out again. Our comparison of self-storage against moving straight in runs those numbers.
Storage is also the wrong answer for anything you are storing because you cannot face deciding about it. That is a decluttering problem wearing a storage costume, and it is the single most expensive version of this because it has no end date by design.
And be careful with damp-sensitive contents. Cardboard boxes in an unheated unit soften over months, and upholstered furniture stored against a cold external wall can develop problems. Rigid boxes, pallets or battens under furniture, and a climate-controlled unit for anything genuinely sensitive are the answers, though the last carries a premium.
One last point on timing. Storage demand and pricing follow the moving market, so the same unit can be dearer in a busy summer week than in November, and availability at popular sites tightens around month ends when tenancies turn over. Booking a fortnight ahead rather than on the day gives you the choice of size and floor, which is where the saving sits.
And take an inventory as you load, photographing each section of the unit once it is full. It costs ten minutes, it makes any insurance claim straightforward, and it saves unpacking half the unit to find one box six months later.
How EcoGreen Movers handles storage
Keeping the move and the storage with one supplier removes a handling stage and a set of paperwork. EcoGreen Movers uses reusable crates that stack squarely and do not collapse in a damp unit over several months, which is exactly where cardboard struggles.
We offer storage and packing alongside residential moves nationwide, with facilities serving Edinburgh, Manchester and London. The move on either side of a storage period comes as Standard for loading and unloading, Standard Plus with furniture dismantled and rebuilt, which is also the cheapest way to need a smaller unit, or Premium with the packing included. Boxes can be bought on their own if you are packing before the unit is filled. Get in touch for a quote covering both legs.
Frequently asked questions
How much for a three-bedroom house?
Around 100 square feet, costing roughly £190 to £250 a month nationally and more in London. That is about the size of a single domestic garage. Annualised, Checkatrade puts a standard 100 square foot unit near £2,310 a year. These are indicative market rates as at August 2026, not EcoGreen Movers quotes.
Is insurance compulsory?
Facilities require contents cover for the whole period, though not necessarily theirs. Many family home contents policies already extend to goods stored away from home, so check yours before buying the product sold at the counter. Expect roughly £5 to £15 a month if you do take theirs.
Why is a small unit so expensive per foot?
Because the fixed costs of letting any unit, the paperwork, access control and site overhead, are spread across less space. The cost per square foot falls steadily as units get larger, which is why one 100 square foot unit beats two 50s.
Is the per square foot figure the price I pay?
No. The widely quoted rate comes from the Self Storage Association UK Annual Industry Report and measures operator revenue per square foot, which was £27.40 excluding VAT in the 2026 edition. Safestore states that these figures do not directly reflect what customers pay. Use them for context, not for budgeting.
Can I get a discount?
Frequently. Half price for the first eight weeks is standard and often unadvertised beyond the website. Committing to six months or more, taking an upper-floor unit, or asking for a price match against a nearby competitor all commonly work, and industry revenue per square foot has been falling, which strengthens your position.
What notice is needed to leave?
Commonly 14 days, though it varies. Check before booking, because clearing the unit early does not automatically stop the charge. Reputable operators run rolling monthly terms with short notice and no exit penalty.
In summary: size it right, then ask for day one total
Budget around £95 to £150 a month for a one-bedroom flat’s contents and £190 to £250 for a three-bedroom house, more in London. Ask for the total payable on day one rather than the headline rate, and diary the date any introductory discount expires.
Then set an end date. Storage taken for a defined gap is a sensible cost; storage taken open-endedly quietly becomes one of the larger bills attached to a move.
