Container office for sale: a UK buyer's guide
When choosing a container office for sale in the UK, check the fit-out, condition and delivered cost for your postcode. Use this guide to prepare a supplier enquiry for a new or used office, or compare hire for a temporary project.
Finished office cabins are not sold through our container shop. The supplier must confirm the available model, specification and price.
Container office purchase price: quote the fitted unit
Ask for the purchase price of the actual office, its condition and included furniture, heating and electrical fit-out. Price delivery to your postcode, offloading and installation separately. No verified UK office-cabin price sample is published here; hire rates also require a supplier quote.
Ready for use
Include delivery, offloading, supports, assembly, water and drainage arrangements, electricity and commissioning before work starts.
Throughout the project
Price cleaning, consumables, tank emptying and water replenishment, maintenance, emergency replacement and final collection.
For purchase, confirm VAT, delivery, installation, included equipment and any repairs or replacements. For hire, also ask for the charge period, minimum hire, extension and notice terms, and collection charges. Commercial hire terms do not change the requirement to provide suitable welfare from the start and throughout the work.
A bare storage container needs a specified conversion before it can serve as a fitted office. For that route, use the container conversions guide to separate the shell from the fit-out and installation work.
Choosing a container office for sale: fit-out and layout
Confirm whether the supplier is offering a converted shipping container or a purpose-built modular office, then compare the actual specification. Describe the number of people present at the same time and what they will do in the cabin. The layout must allow space for furniture and circulation.
Workstations
Number of desks, screens, sockets and storage. Specify whether people work there every day or visit occasionally.
A meeting room
Number of participants, table size, presenting drawings and optional screen. Request a furnished layout to check circulation.
A reception or gatehouse
Visibility from the entrance, waiting area, confidentiality and visitor access arrangements.
An evolving office
Future relocations, team changes or the need to expand. Have the assembly options of the proposed model checked.
Office cabin floor area: request a furnished layout
An advertised floor area does not tell you how many workstations will be comfortable. Check the internal space after partitions, openings, storage and furniture access.

Furniture, heating, air conditioning: confirm what is included
Request a list of the equipment provided with its condition, then the price of any necessary options. A commercial illustration is not enough to confirm them.

Comfort
Heating, optional air conditioning, ventilation, sun protection and floor insulation.
Electrical equipment
Lighting, number and location of sockets, required power and internet connection to arrange.

For a used purchase, ask for recent photos of the interior, floor and equipment. Get any necessary repairs and replacements quoted.

Lorry and offloading
Gate width, turns, overhead obstacles, manoeuvring space and distance between lorry and installation point.
Ground and supports
Ground condition and desired location. Have the supports and installation validated by the supplier before delivery.
Power and network connection
Available power, distance to the connection, planned equipment and internet needs. Have it confirmed who will make and check the connection.
Schedule
Installation date, possible assembly, handover and commissioning. For hire: minimum charge, extension and collection.
Documents to request before installationPlan, electrical specification and installation instructions for the proposed model.ExpandCollapse
- Dimensioned plan and furnished plan, weight of the equipped unit and support and handling instructions.
- Electrical connection details, power of the selected appliances and planned commissioning.

The model's specifications appear on its supplier listing; services specific to your location must be described in the quote.
An office does not replace the site's welfare provision
For construction work, these provisions come from CDM 2015 Schedule 2 in England, Wales and Scotland, and CDM 2016 Schedule 3 in Northern Ireland. Plan them before work starts and keep them available throughout the work.
Safe drinking water throughout the working day
An adequate supply of wholesome drinking water must be readily accessible. Mark drinking supplies where health or safety requires it. Provide suitable drinking vessels unless people can drink easily from a water jet.
Include in the specification: State who replenishes and checks mains, bottled or stored water. Keep drinking water protected from contamination and distinguish it from non-drinking supplies.
Legal provisions: paragraph 3 of GB Schedule 2 / NI Schedule 3.
Rest, meals and boiling water
Provide accessible rest rooms or areas with enough tables and seats with backs for simultaneous users, arrangements to prepare and eat meals, and a way to boil water. Maintain an appropriate temperature. Provide for pregnant or nursing workers to rest lying down where necessary.
Include in the specification: Agree break-time occupancy, food preparation, heating and ventilation. Keep the space clean and free of stored plant, tools and materials; an office label alone does not make a cabin a suitable rest area.
Legal provisions: paragraph 5 of GB Schedule 2 / NI Schedule 3.
Use HSE's checks to plan toilets and washing and changing, drinking water and rest. For Northern Ireland, check who is responsible under HSENI's guidance.
If the office is also the rest or meal area, it must remain available for breaks and provide the required tables, backed seating, temperature, food preparation and boiling water. Continue to provide suitable toilets and washing, plus changing, drying and showers where needed. An office occupied for meetings cannot simply be counted as an available rest room at the same time.
An office cabin with integrated toilet or sanitary facilities?
Specify this requirement from the quote stage: it changes the internal layout, working space and connections. Compare a combined unit with separate office and toilet facilities.
Three points to clarify
- The users concerned and the sanitary facilities already available on site.
- Suitable toilets and nearby washing with clean hot and cold or warm water, soap and drying; showers where the work or health risks require them.
- Water supply, drainage and maintenance, or a suitable solution if services are not available.
See the guide to sanitary and changing room cabins. For all site facilities, our site welfare guide presents the points to be validated according to your situation.

Your questions about office cabins
How much does a site office cabin cost?
Request a current quote for the specific fitted office, furniture, services and installation. This page does not publish a verified UK office-cabin price sample. Include VAT, delivery, offloading, connection work and collection for hire.
Is it better to hire or buy a site office?
Compare the total cost for your use: hire charges and collection at the end of the hire; purchase, possible assembly, maintenance and relocation after purchase. Allow for an extension or future reuse. There is no payback period that applies to every project.
What floor area should you allow for an office cabin?
Start with the number of people present at the same time, meetings and furniture to be installed. Ask for a furnished layout with the internal dimensions of the proposed model, then check circulation and access. The stated floor area alone is not enough.
Are furniture and air conditioning included?
They must be detailed in the quotation. Have it made clear which equipment is provided, which are options and their installation. A photo of a furnished office does not confirm that the furniture or air conditioning are included in the price.
Can you order an office with a toilet?
Specify the equipment required and the users. Ask for a plan of the combined unit and a quote for the connections, then compare with using two separate units.
