Construction Subcontractor Confidentiality & Non-Disclosure Agreement (NDA)

Protect Your Customers, Pricing, Drawings & Business Information

It only takes one subcontractor to walk away with your customer, your pricing or your project information.

Every day, construction businesses share confidential information with subcontractors to get the job done. Customer details, project drawings, quotations, supplier pricing, technical documentation and commercial information are often passed between businesses without any formal confidentiality agreement in place.

If that information is misused, shared with competitors or used to win work directly from your customers, the damage can extend far beyond a single project.

Our Construction Subcontractor Confidentiality & Non-Disclosure Agreement (NDA) has been developed specifically for UK construction businesses to help protect the information you've worked hard to build.

Unlike generic NDA templates, this agreement is written around the real issues contractors face when appointing subcontractors, helping you protect customer relationships, commercially sensitive information, technical documentation and your business reputation.

Is This Agreement Right for Your Business?

If you've ever worried about a subcontractor:

Contacting your customer directly after completing a project.

Using your quotations or pricing to compete against you.

Sharing project drawings, specifications or technical information.

Posting photographs of your work on social media.

Using your supplier pricing, merchant accounts or commercial information for personal gain.

Leaving with years of knowledge about how your business operates.

Then this agreement has been written with those risks in mind.
