What you need to know
- Under unamended NEC4 ECC, the Contractor’s title to Plant and Materials can pass on entry into the Working Areas.
- JCT title mechanisms depend on the form, edition and payment provisions; distinguish DB 2016 from DB 2024.
- A delivery note supports a delivery date. It does not prove good title, transfer risk or settle an insolvency dispute.
Your Client says the steel on site is theirs. Can you show when it crossed the boundary of the Working Areas?
Receipt, ownership and payment are separate questions. Under the standard NEC4 ECC title mechanism, entry into the Working Areas or off-site marking can transfer whatever title the Contractor has. JCT uses a different mechanism for unfixed materials. First check the executed contract, the supply terms and whether the Contractor had title to pass. Source: NEC title guidance.
This is a practical guide for QSs and commercial managers, not legal advice. Title and insolvency disputes turn on their facts and the exact contract wording, so take advice when it matters.
The rule that sits over everything
A main contract cannot simply transfer title the Contractor does not hold, although legal exceptions and supply-chain arrangements can matter. If a supplier or Contractor becomes insolvent, check who owned the identified goods immediately before the insolvency, where they are and whether they have been incorporated into the works.
For unfixed goods, retention-of-title terms can affect the answer. Do not assume that an unpaid supplier always owns them, or that payment to the Contractor clears every supply-chain issue. Goods incorporated into the land raise different questions. Get advice before removing, selling or paying again for disputed materials. Source: BCLP ownership analysis.
That's why your supply chain paperwork matters as much as the main contract. It's also why the first record to check after a supplier failure is your own supply terms, not the delivery note.
How title passes under NEC4
Section 7 of the ECC contains the title provisions. The summary here concerns the standard wording; payment and valuation differ by main Option. Check the amendment set, Z clauses and supply-chain documents before applying it.
Materials within the Working Areas. Clause 70.2 transfers whatever title the Contractor has when Plant and Materials enter those areas. Removal with the Project Manager’s permission transfers title back under that clause. Payment is not the trigger. Source: NEC title guidance.
Working Areas is a defined term, not every place the Contractor happens to store goods. Check the Site boundaries, qualifying areas in Contract Data and any accepted additions. Plant and Materials are intended for the works; the Contractor’s construction Equipment is a different category.
Materials outside the Working Areas. Clause 70.1 uses the Supervisor’s marking as the title trigger. Clause 71.1 links marking to items identified for payment and prepared as the Scope requires. Do not assume a label applied by the supplier is the Supervisor’s contractual marking. Source: NEC title guidance.
For off-site materials, agree how the items are identified, prepared for marking, stored and accessed. Check that the contract identifies the relevant items for payment. A delivery note alone does not satisfy those arrangements.
Security. The standard ECC has no dedicated off-site materials bond mechanism. X13 concerns a performance bond and X14 advance payment; neither is automatically an off-site materials bond. Any additional security needs appropriate drafting and advice. Source: NEC title guidance.
Risk and insurance. Ownership does not, by itself, decide who bears loss or who must insure the goods. Read the liability, care and insurance provisions separately, including off-site storage and transit cover.
How title passes under JCT
JCT form and edition matter. The public DB 2024 contents confirms that clauses 2.21 and 2.22 address on-site and off-site materials, but it does not establish their full wording. The explanation below is based on published analysis of DB 2016. Verify the executed edition before relying on it. Source: JCT DB 2024 contents.
Unfixed materials on site. Published analysis of JCT DB 2016 clause 2.21 explains that ownership generally passes when the materials’ value is included in an interim payment and that payment is made. Inclusion in a valuation and actual payment are different facts. This summary is not a verified quotation of DB 2024. Source: BCLP ownership analysis.
Off-site materials. JCT DB 2016 uses Listed Items under clauses 2.22 and 4.15. Identification, storage, payment and any required bond must be checked against the executed form. JCT publishes off-site materials bond forms for the 2024 suite; a bond provides financial security and does not itself establish ownership. Sources: BCLP ownership analysis; JCT off-site materials bonds.
Keep applications, certificates and payment records itemised enough to identify the goods. Do not assume an unexplained lump sum proves which materials were paid for. The legal outcome depends on the actual wording and evidence.
Where the net payment is nil, or a separate vesting certificate is used, do not assume ownership either has or has not passed. Ask a lawyer to examine the precise trigger and payment documents. No case-specific rule about nil payments is asserted here.
Side by side
NEC4 ECC (unamended) | JCT DB 2016 summary; check executed edition | |
|---|---|---|
Materials on site | Entry into Working Areas transfers whatever title the Contractor has (70.2) | Generally inclusion in interim payment plus payment (DB 2016, 2.21) |
Is payment needed? | No | Generally under DB 2016; verify special vesting wording |
Materials off site | Supervisor’s marking; check payment identification and preparation (70.1/71.1) | Listed Items; check the executed payment, identification and storage conditions |
Off-site bond | No dedicated standard mechanism; arrange suitable security | Standard bond forms available; requirement depends on contract |
Key trigger document | Delivery/gate record and defined boundary; also evidence of good title | Itemised valuation, payment and supply-chain title evidence |
Key off-site record | Supervisor's marking record | Listed Items schedule, bond, identification and storage evidence |
Why the delivery date matters under NEC4
For the NEC4 on-site mechanism, establish when the identified goods entered the defined Working Areas. For JCT’s payment-linked mechanism, establish which goods were valued and what payment occurred. Both still need supply-chain title evidence.
A delivery note, gate record and site diary can support the arrival date and location. They do not establish ownership on their own. Retain them with the purchase terms, item identification and payment records so the legal position can be checked.
A prompt photo is one useful habit, but no single record settles title. Keep the chain from supplier to Contractor to Client, and distinguish unfixed goods from materials already incorporated into the works.
What to keep on each contract
These are our recommendations, not contract requirements.
On an NEC4 job:
- A delivery record for every delivery into the Working Areas: date, time, supplier, ticket number, quantity checked, description and a photo.
- A record of anything removed from the Working Areas, and the Project Manager's permission where needed.
- For off-site materials, the Supervisor's marking record, photos of the marked items and their storage location, and evidence they meet the Scope's marking requirements.
- Test and inspection notifications where the Scope requires them before delivery.
- Your supply chain terms, so you know whether you had title to pass.
On a JCT job:
- A clear breakdown of materials in each valuation, so you can show which items were included and paid.
- Delivery records to show what was on or adjacent to the site at each valuation date.
- For Listed Items, the schedule, evidence of identification and separate storage, and the bond where required.
- Your supply chain terms.
On both, a site diary that records deliveries against dates and locations makes all of this far easier. Our materials delivery log template is a starting point.
Practical steps for QSs
- Check the supply terms and retention-of-title wording. Confirm that the identified goods and the chain of ownership match your main-contract assumptions.
- Record deliveries on the day, with a photo and quantity. Under NEC4 it evidences the title trigger.
- Record the unloading location and the applicable Working Areas boundary. GPS metadata can support the location, but accuracy, permissions and capture method matter. It does not prove ownership or exact boundary crossing by itself.
- Keep itemised applications, certificates and payment records. An unexplained lump sum may leave you unable to show which materials were covered.
- Plan off-site materials early. Under NEC4, agree the marking requirements in the Scope and decide whether you need a bond by amendment. Under JCT, agree Listed Items and bond requirements before the materials are made. Our long lead procurement register helps track what's coming.
Gather records delivery notes within the shift record, alongside the day’s work and resources. Its Record product page also describes photos with timestamps and GPS metadata. These records support a delivery history; they do not, by themselves, confirm the quantity received or prove that materials were used. See the Gather Record product page or book a demo.
FAQ
Does paying for materials give the Client ownership under NEC4?
Payment alone is not the standard NEC4 title trigger. Entry into the Working Areas or qualifying Supervisor marking transfers whatever title the Contractor has. Check amendments and whether the Contractor had good title. Source: NEC title guidance.
Can the Client own materials the Contractor hasn't paid the supplier for?
Possibly, depending on the supply terms and applicable law. Non-payment does not automatically establish that the supplier retained title. Check the chain of title, any retention clause and whether the materials remain unfixed.
Is a delivery note proof of ownership?
No. It is evidence of delivery. Ownership depends on title, the applicable contractual trigger and the circumstances. Keep the supply and payment documents too.
