The comparison that matters
Compare portable cabin quotes against the same use, layout, specification and site conditions—not just the headline price. Establish what is included in the building, then check transport, lifting, foundations, access works, utilities and handover. Record each item as included, excluded, provisional, by others or not yet confirmed. A cabin delivered to site is not necessarily a workplace ready to occupy. Check the approval route separately and ask who is responsible for each stage. Send KC your intended use, approximate size and site postcode first; highlight missing information so it can be considered rather than quietly assumed.
Who this guide is for
- Contractors and site managersComparing office and welfare accommodation for a defined project.
- Facilities and estates teamsAdding workspace without leaving site responsibilities unclear.
- Business ownersBalancing room layout, customer-facing finishes and total expenditure.
- Council and procurement teamsPreparing a consistent brief and a traceable comparison.
Choose the route before comparing prices
For portable office cabins, welfare accommodation or a linked building, start with the intended workplace. These requirements need different briefs. Explore KC’s portable cabins for the commercial overview; use the table below to identify what your enquiry should resolve.
| Situation | Route or checks | Why it matters | Next step |
|---|---|---|---|
| One office or supervision room | Assess a self-contained cabin against a furnished layout. | The external footprint alone does not establish usable workspace. | Share desk numbers, storage and visitor needs. |
| Office plus welfare rooms | Coordinate toilets, washing, rest space and services. | Room arrangements and connection responsibilities need to work together. | Provide the workforce brief and utility information. |
| Several rooms or a larger workplace | Review a coordinated modular scheme rather than separate units alone. | Interfaces, circulation and the overall design affect the scope. | Send a room schedule and site plan. |
| Restricted access or uncertain ground | Review delivery, positioning and the foundation approach before fixing the package. | An attractive building price does not resolve a difficult installation. | Provide access photos, dimensions and available surveys. |
On smaller screens, scroll the table horizontally. Keyboard users can focus the table area.
Start with the rooms, not the outside dimensions
Ask for a scaled plan with furniture, door swings and circulation shown. Record whether quoted dimensions and floor areas are external or internal, and use the same basis when comparing offers.
For example, “four workstations, a meeting space, storage and a toilet” is a more useful starting brief than “a small office cabin”. This is an illustrative requirement, not a claim that those rooms fit a particular module. The layout needs to demonstrate the fit.
For several departments or more complex circulation, compare modular office layouts before fixing the unit count. Do not assume that independently specified cabins can simply be connected.
Compare portable cabin prices per square metre carefully
It is a useful comparison only when the area definition, specification and included works are comparable. Keep the layout and scope beside the figure. Otherwise, a lower rate may describe a different building or a smaller supply package.
Portable cabin quotes: compare these scope lines
Ask each supplier to price the same brief and label the status of every item. “Not mentioned” is not a useful inclusion. Where an allowance is provisional, record its basis and what could change it.
| Quote line | Record for each supplier | Close the gap |
|---|---|---|
| Building and fit-out | Drawing revision, room schedule, finishes, fittings and equipment. | Confirm what is supplied, fitted and left for site work. |
| Technical specification | Proposed construction, performance information and design assumptions. | Ask for evidence relevant to the actual configuration and use. |
| Delivery and positioning | Transport, unloading, lifting, site attendance and access assumptions. | Identify responsibility for the lift plan and any traffic arrangements. |
| Groundworks and foundations | Design responsibility, surveys, formation levels and construction scope. | Identify what must be designed and completed before delivery. |
| Utilities and drainage | Internal services, external runs, connection points and final connections. | Show precisely where each contractor’s responsibility starts and ends. |
| Entrances and external works | Steps, ramps, landings, paths and making good where required. | Check the complete route into the building, not just the entrance door. |
| Approvals and design support | Drawings, calculations, submissions, fees and named responsibilities. | Distinguish design support from approval by the relevant body. |
| Commissioning and handover | Testing, applicable certificates, instructions and acceptance arrangements. | Define what must be complete before occupation. |
| Commercial terms | VAT basis, payment stages, quote validity, variations and written warranty terms. | Identify exclusions, maintenance obligations and who provides each warranty. |
Compare each line as included, excluded, provisional, by others or not confirmed.
Build a comparable total without double-counting
Start with the quoted works. Add separately priced items needed to reach the same scope, and show unresolved allowances separately. Do not add delivery or installation again where they are already included. Keep VAT on a consistent basis and label estimates clearly.
For a practical comparison, imagine one offer covers the fitted cabin only and another also includes agreed delivery and positioning. Neither headline tells you the full difference until the outstanding works are priced. This is an example of comparison logic, not a KC price or case study.
Make your scope clear before requesting prices
Send the use, room requirements and postcode, together with the site information you already have. Mark unknowns so they can be reviewed.
Resolve the boundary between factory and site work
Ask which fittings and services are completed in the factory, which connections remain on site and who is responsible for them. A toilet fitted inside a cabin does not establish where its waste will discharge. An electrical installation inside the unit does not establish the available site supply.
Check access and lifting before booking delivery
Provide the approach route, gate dimensions, turning space, proposed building position and photographs of overhead or nearby obstructions. Ask the delivery team to assess these details; do not select lifting equipment from photographs alone. HSE’s guidance on planning lifting operations explains the need for competent planning, suitable equipment and clearly assigned responsibilities.
Use KC’s delivery and installation checklist to prepare the discussion. Foundation design, ground conditions, lifting arrangements and services must be coordinated for the site; this article is not an installation method statement.
Separate delivery from readiness to occupy
Ask for a programme that distinguishes design agreement, approvals, manufacture, site preparation, delivery, connections and handover. Request the assumptions behind the dates and identify decisions that you or your advisers must make. Do not treat a manufacturing estimate as an unconditional occupation date.
Check evidence, not blanket compliance labels
Ask what the proposed specification is intended to achieve and which documents support it. Check the scope and holder of supplier certificates; they do not automatically become KC-held certification. For warranties, request the written cover, exclusions, provider and maintenance conditions for the particular order.
Planning and building control are different checks
Do not assume that “portable” or “temporary” removes the need for approval. Establish the planning position for the site and intended use. GOV.UK distinguishes building-control approval from planning permission; your project may require both.
For projects in England, use the Approved Documents collection as a guidance starting point, not as a certificate for a proposed cabin. Confirm the applicable edition and route with the project team. Wales has its own Approved Documents; Scotland and Northern Ireland also have their own systems.
Match the review to the intended use
Ask the designers to address the relevant structure, fire, thermal, ventilation, accessibility and services requirements. Record the construction being assessed rather than relying on a generic product brochure. For non-domestic projects in England, Approved Document M Volume 2 is the relevant access-guidance volume—not the dwelling categories in Volume 1.
For construction welfare, a cabin is only part of the arrangement. HSE’s welfare guidance covers facilities for workers and the responsibilities for providing them. Assess the workforce, activities, availability and upkeep, then use the modular welfare units page for the building enquiry.
Buying or hiring: use the same comparison period
When considering purchase and hire offers, ask what each arrangement covers over your expected period of use. For hire, clarify the hire term, extension arrangements, delivery, collection, maintenance and return conditions. For purchase, clarify the supply package, maintenance obligations and any future relocation requirements.
Compare written terms rather than assuming that one route is always cheaper. Confirm the available commercial options for your project; this guide does not promise stock, a particular hire package or a finance offer.
What remains project-specific
This guide concerns non-residential workplace enquiries, including offices and site accommodation. It does not specify a sleeping, residential, clinical or teaching environment. Those uses need a separate brief and review.
Suitability, approvals, fire strategy, accessibility, foundations, utilities, drainage, delivery access, scope, price and programme depend on the project. Examples are illustrative, and no fixed warranty, certification, rating or approval is promised here. Confirm responsibilities and the final specification in writing.
What KC needs to quote
Start with the essentials. Add what is available and write “not yet confirmed” where information is missing.
- Use and people: intended activities, normal occupancy and visitor needs.
- Size and rooms: approximate dimensions or a room schedule, including toilets, kitchen facilities and storage.
- Duration: temporary or permanent requirement and any expected future relocation.
- Location and timing: site postcode and target occupation date. Identify the actual site, including projects around Stoke-on-Trent, Staffordshire or the wider UK.
- Access: approach route, gate widths, turning space, obstructions and working-hour restrictions.
- Services: available power, water and drainage, connection locations and known limitations.
- Groundworks: available surveys, foundation status, level information and any appointed contractor.
- Finish and budget: external appearance, internal expectations and a budget direction where available.
- Supporting information: drawings, sketches, photographs and the current planning or building-control position.
An incomplete brief can still start a discussion. Separate known requirements from assumptions so that the proposal can make clear what is included and what still needs investigation.
Questions about portable cabin quotes
How much do portable cabins cost in the UK?
There is no useful universal figure without a defined size, use and specification. Ask for the building price and any delivery, installation, foundation and connection costs to be separated or clearly included. Check whether VAT and provisional allowances are shown on the same basis across quotes. For an early budget, give each supplier the same room schedule and site information, and ask them to identify assumptions. Treat an indicative estimate differently from a written quotation with an agreed scope.
What should a portable cabin quotation include?
A useful quotation should identify the drawings and specification being priced, included works, exclusions, allowances, responsibilities and commercial terms. Ask for the delivery assumptions, site requirements and handover deliverables to be recorded too. Where work is by another contractor, make the boundary clear: for example, who brings the electrical supply to the cabin and who makes the final connection. Record unresolved items before placing an order rather than assuming they are included.
Are portable cabins different from modular buildings?
The descriptions overlap, so do not use the label as a substitute for a specification. A portable cabin may provide a self-contained room or form part of a larger modular arrangement where the system permits. Compare the proposed structure, room layout, intended use and installation method. For a larger office requirement, investigate a coordinated modular layout rather than assuming that separately quoted cabins can simply be joined. Ask the supplier to confirm how the particular system is designed to work.
Do portable cabins need planning permission?
Do not assume that a movable or temporary building avoids planning checks. Establish the position for the particular site and intended use with the relevant planning authority or adviser before committing. Building-control requirements must be considered separately; resolving one process does not resolve the other. The GOV.UK planning guidance provides an England-and-Wales starting point. Confirm the applicable national rules, any existing permissions and the project information needed for a site-specific decision.
Can portable cabins include toilets and a kitchenette?
Include these rooms in the initial brief rather than treating them as a later furniture change. Ask for a coordinated layout showing usable room sizes, access, plumbing routes and the boundary between factory work and site connections. Tell the supplier what water, power and drainage are available. For construction welfare, assess the facilities against the workforce and activities, including their operation and upkeep. A drawing containing a toilet and sink is not, on its own, evidence that the full welfare requirement has been met.
What happens after I send my brief to KC?
KC’s enquiry process starts with the use, approximate size, location and other project details. The team reviews likely system suitability, access, utilities and information gaps, and may need clarification before preparing a useful proposal. Send the information already available, but mark unknowns rather than guessing. Make the target occupation date clear and distinguish it from a preferred delivery date. The final scope, specification, programme and responsibilities need to be confirmed for the individual project.
Your next step
Give your quotation a clearer starting point.
Send your intended use, approximate size and site postcode. KC can review the likely route and the information needed for a project-specific quotation. Include drawings and site photographs where available.
