Three checks prevent most problems. First, confirm what your local authority will classify the unit as once it is permanently sited, and get that in writing. Second, get a local price for the work after the port β haulage, lifting, foundation and connections β because those costs are not related to the unit price and are where budgets move. Third, ask for the structural drawings and the insulation specification before you order.
On the unit itself, look at four things: how the shell was reinforced at every opening, what insulation is used and how the vapour strategy works, what documentation arrives with the electrical installation, and what the structural warranty actually covers. A supplier who can answer all four promptly is building to a standard you can inspect.
On payment and delivery, understand the terms clearly before committing: units are sold port-to-port (FOB) with payment by bank transfer in full before production, and the buyer arranges local transport and site works from the arrival port.
Getting a real number
Send your destination postal code and the model you are considering, and we take that to a customs broker and return an all-in delivered figure β unit, ocean freight, duty and brokerage β usually within one business day. There is no online checkout and no obligation: the quote opens the conversation rather than closing it.
Payment is by bank transfer in full before production, and units are delivered port-to-port (FOB); you arrange local transport from the arrival port to your site. We work factory-direct with a single vetted manufacturer, so the price you see is the same price a retailer would pay, with no distributor margin layered on top.
