FAQs

What is a converted shipping container?

A converted shipping container is a standard steel shipping container professionally modified and customised to create a functional modular space for commercial, industrial, or retail use. At S Jones Conversions, our bespoke container conversions are built to UK standards and can be transformed into:

  • Equipment housing enclosures and switchgear rooms
  • Battery storage containers and generator housing
  • Workshops, laboratories, and R&D units
  • Retail spaces, pop-up shops, and portable offices
  • Plant rooms and secure storage facilities

Our container modifications can include:

  • Fire protection for safety compliance
  • Thermal insulation and lining for year-round temperature control
  • Ventilation systems to protect equipment and comfort staff
  • High-security personnel and roller shutter doors
  • Double-glazed windows for light and energy efficiency
  • Full electrical installations and climate control

With over 40 years’ experience in UK container conversions, we offer fully bespoke builds and ready-to-deliver standard units with nationwide delivery from our Midlands workshop.

How long does a shipping container conversion take?

Timescales vary based on design complexity and features:

  • Fully customised builds – 6–12 weeks (offices, workshops, labs, switchgear rooms)
  • Standard conversions – often available for immediate dispatch

We provide a clear project timeline from day one and offer the option to visit our Midlands facility to see your conversion in progress.

Common upgrades include:

  • Adding doors and windows for improved light, ventilation, and access

Shazia was helpful from my first enquiry to the delivery of my container. She sorted any query and enabled me to buy exactly what I was looking for. The driver who delivered container was also a credit to his company. Nothing was too much trouble and everything done with a smile .
