Please check your nearest location page for current availability.
8 ft Container Units
Good for smaller loads - fixtures, fittings, smaller tools or materials for a single trade or phase of work.
20 ft Container Units - 160 sq ft
The size most construction customers choose - enough for a substantial volume of materials, tools and equipment while keeping things organised by job or phase.
40 ft Container Units
Built for larger volumes - bulk materials, multiple trades' worth of equipment, or a main contractor consolidating storage across several active sites.
Need More Space for Construction Equipment?
When your project requires additional storage capacity, our larger container options provide secure space for plant equipment, scaffolding, tools and bulky materials. Ground-level access also makes loading and unloading straightforward.

What You'll Find at Our Sites
Whichever of our London or Hertfordshire sites is closest to your current project, expect the same standard:
- A fully fenced compound with keypad-controlled access
- Ground-level containers with direct vehicle access
- LED lighting across the site for early starts before sunrise
- Clean, ventilated units with lighting and power available on request

Site visits by appointment, Mon–Fri, 9am–5pm.
When you book a storage container with us you will receive a phone number to call to open the gate.
Customers are responsible for providing a lock and for ensuring their unit is locked prior to leaving the site. Notice terms for ending your storage are set out in our Terms and Conditions.
All goods stored with us must be insured for their full replacement value. You can use your own insurer, but we recommend Store Protect, our cover designed specifically for self storage, with protection up to £50,000.
Please don’t store flammable materials, chemicals or perishable food. The full list is in our Terms and Conditions.
Security for Materials, Tools and Plant
Construction stock represents a serious investment, and it needs protection to match:
- 24/7 recorded CCTV across every site
- Gated keypad entry for registered customers only
- LED security lighting after dark
- On-site alarm systems
- Individual padlocks on every container
- Ply-lined, clean and ventilated units to protect materials from damp

Who Uses Our Storage Site
Built Around How Construction Projects Actually Run
Projects change week to week, and so does what needs to be stored. Here’s who typically uses us.
The Main Contractor Running Several Sites at Once
When materials, tools and plant need to move between sites depending on where the work's happening that week, having a secure central point to store and redistribute from keeps things a lot less chaotic than everything living on one cramped site.
The Renovation or Extension Specialist Between Phases
Kitchen strip-outs, loft conversions and extensions all generate a phase where fittings, fixtures and materials need somewhere safe to sit until they're needed again. A container keeps them out of the way and out of the weather.
The Subcontractor Storing Specialist Tools and Materials
Electrical first-fix kit, plumbing supplies, plastering materials - whatever your trade needs on-site, having a secure base nearby means you're not transporting everything back and forth every single day.
The Small Developer or Self-Build Project
If you're managing a build yourself rather than through a single main contractor, you're often the one responsible for storing materials safely between deliveries and use. A unit gives you a proper answer instead of a tarpaulin in the garden.
The Demolition or Site Clearance Business
Reclaimed materials, salvaged fittings and equipment used across multiple clearance jobs need somewhere secure between projects rather than sitting on a lorry or an unsecured site.
The Tool Hire Business Needing Overflow Space
When your own premises are full, or you need a second base closer to active sites, a container gives you secure space for tools and equipment between hires.
Why People Choose Wow Storage for Storage Across London
Why Construction Businesses Choose Wow Storage
Site cabins fill up fast, and leaving materials or tools on an active site overnight carries real risk. Our sites are built to take the pressure off.
Drive-up access built for construction loads
Every container is at ground level with drive-up access, so you load and unload without carrying materials through a building.
Practical storage, not just a locked box
Lighting in every unit, ventilation to protect materials and equipment from damp, and power available on request if you need it.
Security suited to genuinely valuable stock
Gated keypad entry, 24/7 CCTV, LED lighting after dark and individual padlocks - considerably harder to target than an unsecured site compound.
Flexible enough to match a project's timeline
Monthly rolling terms mean you can take on space for the length of a project and give notice once it wraps up, rather than being tied to a fixed-term contract that outlasts the job.
Set up to protect equipment, not just store it
Lighting in every unit, ventilation to stop damp getting into engines and machinery, and power available on request if you need to charge or maintain equipment on site.
Security that's a genuine step up from a garden shed
Gated keypad entry, 24/7 CCTV, LED lighting after dark and individual padlocks - considerably harder to target than a domestic garage or an unlocked outbuilding.
