Can You Store a Car in a Shipping Container? (Honest UK Guide)

Project car, second car, a classic laid up for winter, a vehicle between insurance policies — the reasons differ, but the question is always the same: can you store a car in a shipping container? Garages are full, driveways get targeted, and not every car deserves to sit on the street through a Manchester winter. Here’s the honest answer, with the real numbers.

The short answer: yes, with a 20ft container

Yes — a car fits in a standard 20ft container. The door opening on a 20ft box is 2.34m wide and 2.28m high, and container specs list the 20ft as suitable for a small to medium-sized vehicle (Freightos). Swift Secure Self Storage Containers in Salford stores cars in 20ft units on a 24/7 CCTV-monitored yard.

That’s the headline. The rest of this guide is about making sure yours is the right kind of car, prepared the right way — because the box is only half the story.

Will your car actually fit through the doors?

Most cars fit: a 20ft container’s door opening is 2.34m wide and 2.28m high, while a Ford Fiesta measures 1,735mm across and a Nissan Qashqai 1,835mm (CarVeto UK dimension data) — both with plenty of clearance. Inside, 5.89m of length takes even large saloons, and 2.39m of internal height clears everything except tall vans.

Width is the number that matters. A Fiesta at 1.735m leaves roughly 60cm of combined clearance through the doors; even a Qashqai-style crossover at 1.835m leaves half a metre to play with. Fold the mirrors in for extra margin. Length is rarely the issue — 5.89m of internal floor swallows anything short of a long-wheelbase van, with room at each end for access. Height is the one constraint: 2.28m through the doors takes low-roof vans but not high-roof panel vans or anything with a roof box. Measure the vehicle, not your memory of it — our size guide shows how to work with the real internal numbers.

10ft or 20ft for car storage?

A 10ft container is too small for a car — its internal floor is only about 2.8m long, so no road car fits. Storing a car means a 20ft unit, which is why Swift Secure Self Storage Containers in Salford sizes every vehicle enquiry on a 20ft from £40/week.

This is where people get caught out by the price list: a 10ft from £25/week looks tempting, but physics wins. A 20ft is the only option for anything with four wheels and a number plate — which also means one car per unit, since 5.89m of internal length holds one Fiesta-length vehicle with sensible room at each end. Our vehicle storage page covers what’s kept on the yard.

SORN, tax and MOT: the paperwork first

If your stored car is untaxed and uninsured, declare a Statutory Off Road Notification (SORN). GOV.UK confirms a SORN needs no renewal, the vehicle must stay in the UK, and you may only drive on a public road to a pre-booked MOT — misuse risks prosecution and a fine of up to £2,500.

The SORN is free, takes effect immediately in most cases, and triggers an automatic refund of any full remaining months of vehicle tax. What it doesn’t remove is common sense: insurance isn’t legally required while SORNed, but laid-up or fire-and-theft cover protects a car nobody checks daily. And the MOT doesn’t pause — it simply isn’t required while the car stays off the road, so budget the re-test into your plans before it rolls out again. Keep the V5C somewhere safe but accessible for when you re-tax.

How to prepare a car for months in a container

Disconnect or trickle-charge the battery, inflate tyres to the high end of their range, leave the handbrake off with the car in gear (or chocked) so brakes don’t seize, wash and dry the car, and allow airflow to manage moisture. Swift Secure’s yard guidance is simple: a clean, dry car under a sound steel roof with 24/7 CCTV monitoring.

Containers are steel, so they follow ambient temperature — our condensation guide explains why that matters. A car that goes in wet breeds surface corrosion under covers, so the wash-and-dry counts for more than any magic product. Skip the plastic car cover if airflow is poor — it traps condensation against paintwork. Tyres lose pressure slowly and develop flat spots over months; over-inflation buys time, and a short roll forward every month or two resets the contact patch. A full tank reduces internal tank condensation on older steel tanks, with stabiliser if the lay-up runs past six months — check your manual. And check on it: open 7 days 9am–9pm gives you plenty of visiting windows.

Container vs garage: which protects the car better?

A steel container on a monitored yard beats most rented garages for car security: steel walls, locking rods and a lockbox-shrouded padlock at the door, plus 24/7 CCTV monitoring across the site. Our security guide breaks down the full setup.

The honest comparison: a brick garage on a quiet street is convenient but often the weakest link — up-and-over doors are a classic target, and out of sight cuts both ways when nobody is watching. A container on an actively monitored yard is harder to breach quietly, and there’s always a camera recording the attempt. The trade-off is temperature: a container isn’t insulated, so it swings more with the seasons than a garage with thermal mass. For a winter lay-up that’s manageable with the prep above; for a concours car, a dehumidified unit is the next step up. For everything in between — the project car, the second car, the inheritance waiting for a decision — the container wins on security per pound.

Electric cars: anything different?

Electric cars store fine in containers with two adjustments: park with the battery at 40–60% charge (never fully charged or fully flat), and check on the 12V battery, which drains like any other car’s. Call 07375 063637 to talk through your EV — the 20ft units, 24/7 CCTV monitoring and 9am–9pm access work the same for electric cars.

EV prep is otherwise the same — tyres, brakes, wash-and-dry, airflow. The battery guidance comes from every major EV maker: lithium batteries dislike sitting at either extreme of charge for months, and the middle of the range is where degradation is slowest. Leave the car unlocked-out of “sleep” modes that wake it repeatedly; deep sleep is what you want. Charging inside the unit isn’t needed for a typical lay-up, and any facility’s rules on charging equipment apply before you plug anything in. One honest caveat: tell your insurer it’s stored — EV valuations make declared storage location matter.
