Can I claim for materials stored off site?

Off-site materials are a stricter question than materials on site, and the first thing to establish is whether your contract permits the claim at all, because many do not without a specific listing or agreement, and amendments frequently tighten or remove the entitlement. Where a form does allow it, the conditions exist for a reason: paying for something you cannot see, in someone else's premises, risks the money buying nothing if the supplier fails or the goods are not actually yours. Typically the goods must be identifiable as intended for this contract, set apart and marked from other stock; ownership must have passed to you or pass on payment, evidenced by a vesting certificate or transfer documentation; and they must be insured against loss or damage while stored. Some forms also require the goods on a listed schedule agreed in advance and may ask for a bond. So an off-site claim is only worth making if the vesting pack is assembled before it goes in, not scrambled together after it is queried, because a claim that cannot survive testing is an invitation to a cut, or a payment clawed back later when a supplier goes unpaid. Get the pack right and the cash comes forward months; get it wrong and you have paid for a risk the contract wrote its conditions to keep off your books.

Take a subcontractor who has commissioned a run of bespoke architectural metalwork, fabricated and finished in the fabricator's yard weeks before the building can take it. On the first attempt the claim is a single line, off-site materials, with the fabricator's invoice attached, and the surveyor cuts it in full: no vesting, no proof of ownership, no insurance, nothing to show the metalwork is even set aside for this job. The rebuilt claim is a folder: a vesting certificate transferring ownership on payment, photographs of the units marked with the contract name and stored apart from other work, the fabricator's insurance confirmation, and the contract clause that lists off-site materials as claimable. This time it is certified, and the cash arrives a month before the metalwork does. The work in the yard was identical both times; what changed was whether the claim could withstand being tested, which off-site claims always are.
