    Container Conversion

    A shipping container is a strong and durable steel container, manufactured to withstand approximately 10 years of shipping all around the world in all weather conditions.

    Standard shipping containers are 20ft in length x 8ft in width x 8ft 6 inches in height, and 40ft in length x 8ft in width x 8ft 6 inches in height (high cube containers are also available at a height of 9ft 6 inches). Steel Shipping Containers provide secure, almost vandal proof storage and are highly recommended by insurance companies. Floors are usually hardwood or plywood 30mm thick, supported on steel bearers at 12” centres. Access is via full width doors at one end, which are approximately 8ft high (doors can be removed and installed anywhere in a container as part of the conversion). Each door has two cam-type locking rods giving excellent security. Containers have an infinite number of uses, and a major advantage is that they can be easily converted in to almost any structure required. They can be cut down, or made larger in length, height or width, or can be joined together with another container, to create a much larger structure to almost any design. All of our containers are adapted or converted according to specific customer requirements. Containers can be modified by the installation of any feature required by the customer. Design features may include any of the following, to give you just a few examples:

  • Electrical fittings, for example, Power Points, Heating (standard heating is a 2kw Convector heater, but own customer’s own specifications can be installed), Air Conditioning, Lighting
  • Internal Lining, Partitions
  • Additional windows or doors
  • Smoke detectors
  • Carpet tiles or durable rubber linoleum flooring
  • Sinks, Worktops, Shelving, etc
  • Plumbing for Kitchens, Showers, and Toilets
  • External cladding
  • External steel shuttering for the windows (operated and locked from the inside) and high security grills

  • Container Conversion

    Upminster Containers Limited specialises in standard and bespoke container conversions and specialised container repairs.

    Upminster Containers Ltd offers a unique container conversion service; handling everything in the conversion process, from the initial enquiry, throughout the entire conversion process, to delivery to your site (and collection if the container or conversion is hired from us). We have a two acre site, boardering both Essex and London, which incorporates a specialist container conversion workshop, enabling us to carry out all adaptations and conversions on our own site by our own highly skilled, and experienced engineers.


    Upminster containers will undertake any type of container conversion. We have been converting and repairing containers for over forty years at our premises here in Essex. Through using Upminster Containers you are able to eliminate the middle man, thus providing a cost effective solution to our customers. All our container and conversions are available for hire or sale, and hire purchase can also be arranged.

    Customers are welcome to supply their own container, or we can supply, choosing from our own stock (new or used) held in our depot, thus eliminating unnecessary logistical expenses.

    Container Conversions

    All containers, for hire, sale or conversion by Upminster Containers are owned by ourselves, and we ensure that we keep a wide variety of containers in stock at all times, stored on our own site, to which customers are warmly invited to visit and inspect. We always encourage customers to visit us, whether to make a general enquiry or to inspect work in progress. No appointment is necessary.

    Steel fabrication, welding, painting and the installation of security lock boxes are all undertaken at our own premises, with our own equipment, saving time and unnecessary haulage expenses. A high standard of workmanship is employed throughout the conversion process, with quality checks carried out at regular intervals.

    On site conversion process finishing (if required) is carried out by our own qualified and insured personnel. Once the conversion has been completed, if your site is not ready to accept the container, we are able to store the container until a time convenient for you. We can then handle and load your container conversion ready for delivery.

    Past conversion projects include: Classrooms, School Common Rooms, Offices, Secure Site Offices, Canteens, Sleeping Quarters, Sandwich bars, Bike stores, Bicycle Hire shops, Mobile Shops, Mobile Canteen/Cafe’s, Workshops, Changing Rooms, Drying Rooms, Welfare Units (self-powered), Toilet and Shower Blocks, Fuel and Chemical Stores, Bunded Chemical Storage Containers, Secure Tack Rooms, Stables, Laboratories, Living Accommodation, Sweet Shop Kiosks. Remember; when you are dealing directly with the manufacturer, the possibilities are endless.

    Throughout the whole conversion process, when you contact us, you can speak directly to an engineer involved in your conversion project. Due to our extensive experience in this field, we find that this eliminates any time consuming and unnecessary communication with intermediaries. This makes vast savings for the ‘end user’ by cutting out the ‘middle-man’. Why pay extra? Come direct to the engineer!

    Customers can make an order by telephone, online or in person, ensuring a prompt and efficient service, and are able to view the containers on our site, before, most importantly during and after the conversion process.


    We do not operate our own haulage, instead we subcontract that part of our business out to ensure that we are able to offer our customers the most competitive rates available.

    We can arrange the transport for you, and have a number of reliable hauliers who we use on a regular basis, all of whom have fully qualified drivers, correctly licenced and insured to deliver efficiently and effectively, and most importantly, carefully with relevant risk assessment and method statements.

    However, all customers have the options of arranging their own transportation from our depot to wherever the container needs to be sited.

    We are also able to offer a container re-positioning service, carried out by one of our hauliers, should you require your container to be moved at all.
