What Storage Units Cost in the UK Right Now
Recent industry figures from the Self Storage Association UK put the national average at roughly £2.43 per square foot per month before VAT. London sits well above that at around £3.67 per square foot, which explains why a 50 sq ft unit that costs £95 to £110 a month across much of the country can reach about £220 in the capital. Central sites in high-demand postcodes push the London premium to roughly 38 percent over the UK average, and the region has seen the steepest price rises of anywhere in the country in recent years.
That gap matters when you compare quotes. A family clearing out a three-bedroom home in Manchester faces a very different bill from someone storing a similar volume near King's Cross. Location is the single biggest factor after size, so "storage units near me" searches often produce wildly different results depending on whether you type a city centre or a commuter town.
The table below shows typical London monthly averages by unit size, based on the latest SSA UK regional benchmarks. Treat them as a guide rather than a fixed quote.
| Unit size | Typical use | Monthly cost (London average) |
|---|
| 25 sq ft | Documents, a few boxes, seasonal items | Around £110 |
| 50 sq ft | Studio or one-bedroom flat contents | Around £220 |
| 75 sq ft | Larger one-bed or small two-bed flat | Around £331 |
| 100 sq ft | Two-bedroom home contents | Around £441 |
Outside London you will generally find 50 sq ft rooms priced between £95 and £150 a month, and a 200 sq ft unit typically runs from £350 upwards. Promotions change the picture too. Big Yellow, for example, regularly offers 50 percent off for the first eight weeks, which can make a short-term rental noticeably cheaper.
Comparing the Main Providers
| Provider | What you get | Price guide | Best for | Watch out for |
|---|
| Big Yellow | Nationwide sites, PIN code access, individually alarmed rooms, CCTV | Mid-to-high, with frequent first-month discounts | Households moving or renovating | Self-service model, so you do the lifting |
| Safestore | Established network, many unit sizes | Higher end of the market | People who want a recognised brand | Contents cover and transport are on you |
| Pickfords | 15 locations, units from 15 to 300 sq ft, drive-up and container options | From about £9 a week in York for a 15 sq ft unit | Those who want on-site staff help | Container storage only at selected sites |
| HOLD (King's Cross) | 24/7 access, no minimum term, no admin fees | From £95.30 a month for a 10 sq ft unit | Londoners who value flexibility | Central London only |
| Keepr, LOVESPACE, Storemates | Collection-based box storage with contents cover included | From about £5 to £7 per box per week | Students and small moves | Limited to major cities or scheduled pickups |
Student storage is a category worth a separate look. If you are storing a term's worth of boxes between academic years, collection-based services remove the need for a van and a friend with a licence. They also suit people who do not want to visit a facility at all. The trade-off is that you give up same-day access and pay per box, so costs climb fast if you overpack.
Choosing a Size That Matches Your Belongings
Most people guess their space needs wrong on the first attempt, and the mistake usually runs in one direction: too big. A useful rule of thumb is that a 25 sq ft room holds the contents of a large wardrobe plus boxes, 50 sq ft suits a studio or one-bed flat, and a 100 sq ft unit handles a two-bed home. Three-bedroom houses generally need 150 sq ft or more, which is where drive-up units and containers at places like Pickfords come into play.
Sarah, a teacher in Leeds, assumed she needed a 150 sq ft unit for the contents of her three-bedroom terrace. She listed everything, then disassembled the wardrobe and bed, packed books into smaller boxes and used the full height of the room. The lot fitted into a 75 sq ft unit, and her monthly bill dropped by more than a third. Her only advice to anyone else: take an inventory before you look at prices, not after.
Access matters too. If you plan to retrieve items regularly, leave an aisle inside the unit, which may mean sizing up slightly. If the room is a long-term home for seasonal gear and family keepsakes, pack it floor to ceiling and save the difference.
Security, Access and the Fine Print
Secure self storage in the UK is a mature market, and most reputable facilities offer CCTV, gated entry, PIN code access and individually alarmed rooms. On-site staff make a difference if you are moving heavy furniture, and some locations offer 24/7 access while others restrict entry to staffed hours. Decide which you need before you book, because the price often reflects it.
There are also clear rules about what can go inside. Hazardous materials, perishable food, flammable liquids and anything illegal are banned at virtually every UK facility. Bikes, tools, archived documents and office equipment are usually welcome, but check individual provider guidelines rather than assuming.
Read the contract for the costs that are easy to miss. Some operators charge an admin fee on top of the advertised rate, others ask for a minimum term, and contents cover is not always included in the base price. The SSA UK publishes guidance on what fair terms look like, and its website includes a facility finder organised by region.
A Simple Booking Plan
- List everything you plan to store, including bulky items such as sofas and white goods.
- Get quotes from at least two providers, including one local facility, and compare per-square-foot rates rather than headline monthly prices.
- Ask what is included: access hours, loading bays, lifts, alarms and contents cover.
- Check whether there is a minimum term and how much notice you must give to leave.
- If a promotional rate is on offer, read the small print about what happens when it ends.
Regional options are broader than most people realise. Edinburgh, Manchester and Tamworth offer container storage, Cambridge and Norwich have larger units for household clearances, and York currently has some of the most affordable small units in the country. Sites like Yell are handy for "storage units near me" searches, but always verify the facility's own terms before paying a deposit.
Start with the smallest unit you genuinely believe you need, pack efficiently, and give yourself permission to trade up later. Most people overestimate their space by a size, and the money saved on a smaller room covers a lot of packing tape.
