Free Contractor Non-disclosure Agreement Template
A contractor non-disclosure agreement covers what counts as confidential on a build, how it can be used, how long it lasts, and what happens if information leaks.
Share template
A tender needs drawings, access notes, and pricing moving between people, but the same details can travel fast once they leave the inbox. The contractor non-disclosure agreement gives both sides one set of terms for what stays private while build information gets shared with the people who need it.
The agreement starts with Both sides agree to keep that, then defines What stays private in plain language, including plans, cost breakdowns, trade rates, site access, and security details. How I keep it quiet limits use to evaluating and delivering the work, covers sharing with subcontractors and suppliers who need the information, and sets out practical handling like limiting copying; the later sections cover What is not covered, How long it lasts, Give it back or delete it, Who owns what, and what the harmed side can ask for If there is a leak. The text sits under Space Grotesk headings with a deep teal and industrial red palette, so the page reads like controlled project paperwork rather than sales copy.
- Both sides agree to keep that Opens the agreement with the shared confidentiality promise and ties the obligation to the purpose of the discussions.
- What stays private Defines confidential information for a build, including drawings, quotes, supplier and subcontractor rates, and site access or security details.
- How long it lasts Sets when the agreement starts and how long confidentiality continues, including a 3-year default from the last shared confidential information.
- Give it back or delete it Covers returning or deleting information when discussions end, plus the limited records either side may keep for business, legal, or insurer reasons.
- If there is a leak Explains what the harmed side can seek if information is disclosed or misused, and carries the Signature block for acceptance.
Once the terms match the job, you fill in names and dates, send it, and both sides sign online. The signed copy gives you something you can point to when drawings, pricing, or site security details need to stay on this project and not become something that gets reused elsewhere.

Questions about this contract template
Do I need an NDA signed before I send drawings?
Many teams get an NDA signed before sending plans, quotes, or site security details, because the signature anchors the duty of confidence to a date. This agreement also covers information shared before tender and during tender, so you can match it to how the discussions are running.
What counts as confidential information on a construction project?
Confidential information includes anything a sensible person would treat as private, even if it isn’t marked confidential. The wording calls out common build examples like drawings, specs, quotes, cost breakdowns, supplier and subcontractor rates, programme notes, and site access or security details.
Does a construction NDA cover subcontractors and suppliers?
The confidentiality duty allows sharing only with people who genuinely need the information for the project, including subcontractors, designers, consultants, and suppliers. The clause also requires that those recipients are bound to keep it at least as tight as the agreement.
How long does a contractor NDA last?
The agreement starts on the date the last person signs it and continues even if the tender doesn’t proceed. The default term is 3 years from the last date confidential information is shared, unless a different period is agreed.
What is not covered by an NDA?
The carve-outs include information that is already public through no fault of the receiving side, information already known before it was shared, and information obtained properly from someone free to share it. The agreement also allows disclosure required by a regulator, court, insurer, or similar lawful process.
What happens if confidential build information leaks?
The agreement recognises that money may not fully repair the harm from disclosure or misuse. The harmed side can ask for an order to stop the disclosure or misuse, and can also claim compensation for losses caused by the breach.
