Containerised sea freight is the backbone of international trade and the safest, most flexible way to move vehicles, household goods, commercial cargo and personal effects out of the UK. TheShipCars Worldwide books direct with the world's largest container carriers — Maersk, MSC, CMA CGM, Hapag-Lloyd, ONE, Evergreen, ZIM and OOCL — and passes the contract rates straight to you.
Whether you need a single 20ft for a relocation, a 40ft High Cube for a vehicle plus household effects, or a few cubic metres of LCL groupage space for a small consignment, we handle UK collection, warehouse loading, bracing, customs clearance, ocean freight and destination delivery guidance under one Bill of Lading.
This page covers container sizes and specifications, FCL versus LCL economics, loading options, transit times, documentation and pricing. For a live quote based on your exact route and cargo, use our instant quote tool below.
20ft general-purpose container
The 20ft GP (general-purpose) container is the workhorse of international shipping. Internal dimensions are 5.90 m long × 2.35 m wide × 2.39 m high, giving roughly 33 m³ of total capacity and around 28 m³ of usable space once doors, ventilation and bracing are accounted for. Maximum gross weight is 30,480 kg with a payload of about 21,600 kg.
A 20ft fits a single saloon, 4×4, van or pickup with 2–4 m³ remaining for boxed personal effects. It's the right choice for solo relocations, single-vehicle exports and small commercial consignments. Per-cubic-metre pricing is higher than a 40ft, but the absolute freight cost is lower.
- 5.90 × 2.35 × 2.39 m internal
- ~28 m³ usable capacity
- 21,600 kg maximum payload
- Fits 1 saloon, 4×4 or small van
- Cheapest sole-use option
40ft container (standard and High Cube)
The 40ft GP container is twice as long as a 20ft (12.03 m × 2.35 m × 2.39 m), with ~58 m³ usable space and 26,500 kg payload. It's the standard for full-house relocations and two-vehicle shipments. The 40ft HC (High Cube) adds 30 cm of height (2.69 m internal), increasing capacity to ~67 m³ — ideal for motorhomes, tall machinery, classic-car restoration projects and large furniture.
Per-cubic-metre, the 40ft is the most economical container format. If you're between sizes, almost always go up: a half-empty 40ft is usually cheaper per m³ than a full 20ft on the same route.
- 12.03 × 2.35 × 2.39 m (GP)
- 12.03 × 2.35 × 2.69 m (High Cube)
- 58–67 m³ usable capacity
- Fits 2 cars or full household
- Best per-m³ rate
Specialist container types
Beyond the standard GP and HC we also book Open Top containers for over-height cargo (loaded by crane through the roof), Flat Rack containers for over-width machinery and boats, Reefer containers for temperature-controlled goods such as wine or pharmaceuticals, and Tank containers for liquids. Specialist equipment is in shorter supply so we recommend booking 3–4 weeks ahead.
FCL vs LCL — which to choose
FCL (Full Container Load) means you reserve the entire container for your cargo. Pricing is a flat per-container rate, sailings are direct (no consolidation delay), and your goods are sealed from origin to destination — no other shipper has access. FCL is the right choice once your volume hits about 14–15 m³.
LCL (Less than Container Load) bundles small shipments into a shared container at the carrier's consolidation depot. You pay per cubic metre or per tonne (whichever is greater), with a minimum charge equivalent to 1 m³ on most routes. LCL is cheaper for shipments under ~12 m³ but adds 5–10 days for consolidation and deconsolidation.
Live load vs warehouse load
A live load delivers an empty container to your address on a side-loader trailer. You have a fixed window (typically 2 hours free, then waiting time charges) to pack and load before the driver leaves. Live loads suit relocations where you're packing from the house directly into the box.
A warehouse load — the option we recommend most often — has us collect your goods, transport them to our bonded warehouse near the loading port and professionally load and brace the container under cover. Costs are similar, supervision is included, and you avoid demurrage risk if loading runs over.
UK loading ports
Containers sail from Southampton (the UK's largest container terminal, owned by DP World), London Gateway (Thames), Felixstowe (the UK's largest single port, Suffolk), Liverpool, Tilbury and Sheerness. We choose the port that minimises inland trucking cost from your collection address and matches your preferred carrier's sailing schedule.
Documentation and customs
UK export requires an HMRC C88/SAD electronic export declaration, a commercial invoice or packing list, and the Bill of Lading. We handle declarations in-house under our own EORI number, so you don't need to register anything. Destination clearance is the buyer or receiver's responsibility — we provide the BL, commercial invoice and any certificates of origin needed.
Marine insurance and protection
Carrier liability under the Hague-Visby Rules is capped at SDR 666.67 per package or SDR 2 per kg — a fraction of most cargo values. We arrange Institute Cargo Clauses (A) all-risks cover for the full declared value, including general average contributions if the vessel is involved in a casualty. Premiums are typically 0.4%–1% of declared value for general cargo.
- All-risks marine cover (ICC-A)
- Door-to-door protection
- General average covered
- Certificate issued before sailing
- Claims handled in the UK
