Brand new or used shipping container: the true TCO calculation
A brand new shipping container costs 40% more than a good quality used one. Is it worth it? We look at purchase price, lifespan, maintenance cost, resale value — in short, the total cost of ownership over 10 years. Verdict by use case.

Our recommendation by usage
- Permanent residence / visible commercial use → Brand new. The aesthetic value and warranty justify the premium.
- Office fit-out, studio, tiny house → One-trip. 90 % of a new container's quality for 15-20 % less.
- Professional regular storage → Grade A used. Best value for money, healthy structure.
- Construction site / seasonal overflow storage → Grade B used. Minimal cost, aesthetics not a priority.
- Intensive maritime use → Brand new or one-trip. Need the CSC stamp valid for as long as possible.
- Temporary project (less than 5 years) → Grade A used. With planned resale. Best net economy.
Frequently Asked Questions
What is the real price difference between new and used?+
On a 20-foot container: new £3,780 – £4,725, one-trip £3,360 – £4,095, Grade A used £2,310 – £2,940, B £1,890 – £2,520, C £1,470 – £2,100. Difference new vs. Grade A used: ~40 %. One-trip vs. Grade A used: ~30 %. So yes, the difference is significant, but it must be put into perspective over the real lifespan.
Does the lifespan really change according to purchase condition?+
Yes, but less than one might think. A new container properly maintained (periodic repainting) lasts 30 to 40 years. A Grade A used container lasts another 20 to 30 years. The lifespan difference (about 10 years) justifies the price gap of 40 % only if your use is very long-term and permanent — rarely the case in practice.
How does resale value behave?+
A new container bought for £3,400 sells for about £2,100 five years later (-37 %). A Grade A used container bought for £2,100 sells for about £1,400 five years later (-36 %). So the used one loses proportionally as much but in absolute terms less. Grade A used is optimal if you plan to resell within 5-8 years.
Total cost of ownership (TCO) over 10 years?+
For a 20-foot container with storage use for 10 years: new at £3,400 + maintenance £430 + resale -£1,700 = £2,100 net TCO. Grade A used at £2,100 + maintenance £600 + resale -£1,000 = £1,700 net TCO. The used one saves £430 over 10 years. Over 20 years, the gap narrows as the new one is still in service while the used one starts needing heavy investments.
For a habitable conversion, new or used?+
For a habitable conversion, highly recommended: brand new or one-trip. Reason #1: the floor. The original wooden floor is treated with bifenthrine (biocide) incompatible with residential use — needs to be replaced anyway. Reason #2: the paint. Used Corten steel often has micro-rust that needs treating before conversion — additional cost 300-£600. Reason #3: final aesthetic matters when you live in it.
