A quote can look straightforward until the job opens up, more people get looped in, and private details start moving around by email and printed plans. The contractor non-disclosure agreement gives both sides a clear rule for what stays private while pricing, planning, and carrying out the work, so the conversation doesn’t turn into a running argument about what can be shared and with who.

The wording walks through what each side treats as confidential, how that information can be used only for the job being discussed, and who it can be shared with when a specialist trade or site lead needs it. The pages run under controlled maroon accents with Zilla Slab headings and Roboto body text, and the last section covers what to do if a leak happens, including steps to limit the spread and the option to ask for an order to stop misuse... because money alone doesn’t always fix the damage.

  • Thanks for talking with us about Opens the agreement in the context of discussing work and confirms that shared information is only for quoting, planning, and carrying it out.
  • What we keep private Defines confidential information in plain terms and lists examples from both sides, including security details, drawings, pricing, and trade contacts.
  • How we both handle it Limits use to evaluating and doing the work, and narrows sharing to people who genuinely need the details for the job.
  • What is not confidential Covers the common exceptions, like information that’s already public, independently developed, or required to be disclosed by official process.
  • Returning and deleting Explains what gets returned or destroyed at the end, and what can stay in backups or job records while still remaining confidential.

Once the agreement is in your workspace, you fill in the names and dates, send it to the other side, and both parties sign online. The signed copy becomes the shared reference point for what can be used, what has to be returned or deleted when discussions end, and how long the duty of confidence continues.

We went from spending hours on every proposal to creating fully customized ones in under 5 minutes. That's not an exaggeration - we timed it.

What to include in a contractor non-disclosure agreement

PartWhat it covers

Thanks for talking with us about

Frames the NDA around discussing work, so both sides can share details for pricing and planning without treating them as public.

What we keep private

Defines what counts as confidential information and gives examples from both parties, including access details, drawings, budgets, pricing, and supplier rates.

How we both handle it

Limits how confidential information can be used and who it can be shared with when someone needs the details to evaluate or carry out the work.

What is not confidential

Lists the standard carve-outs, including public information, prior knowledge, independent development, and legally required disclosure.

When this applies

Pins down when the duties start, what stages the agreement covers, and how long confidentiality continues after discussions or work end.

Returning and deleting

Covers returning or securely destroying materials, with guidance on what can stay in routine archives for records, insurance, or tax.

Who owns what

Confirms each side keeps ownership of its own ideas and materials, and limits permission to reviewing and using information for the agreed work.

If there is a leak

Explains the remedies if information is misused, and includes a Signature block so both sides can sign and act quickly if something goes wrong.

Who it is for

Contractors, trades, and project managers sharing plans, pricing, access details, or site documentation with a client before or during renovations and new builds.

The contract in full

Thanks for talking with us about home building work. As part of pricing, planning, and getting a job set up properly, we may both share information we would not normally publish or hand to a stranger.

It means we both agree to treat the other’s confidential information with care and to use it only for discussing, quoting, planning, or carrying out the home building work we are talking about.

What we keep private

“Confidential information” is anything either of us shares that a sensible person would treat as private, whether it is marked confidential or not. For you, that can include your address and access details, alarm or key safe codes, drawings, structural calculations, surveys, photos of your home, budgets, and your family’s day to day routines while you are living in.

For us, it can include pricing and estimates, supplier rates, programme and sequencing, variation quote sheets, subcontractor contacts, method statements, checklists, and how we coordinate Building Control inspections and sign-off. It also includes logins, passwords, and any files shared by email, link, USB drive, or printed pack.

How we both handle it

We both agree to use the other side’s confidential information only to evaluate, agree, or carry out the home building work being discussed. We will not use it for any other job, any marketing, or to gain an advantage with someone else.

We both agree to share confidential information only with people who genuinely need it for that purpose, for example our project manager, site supervisor, estimator, or a specialist trade we bring in for a specific part of the job. If we pass information on, we will make sure those people are bound to keep it private to at least the same standard. We will protect it with the same care we use for our own confidential information, including keeping site copies and digital files controlled and not left lying around.

What is not confidential

Information is not confidential if it is already public through no fault of the receiving side. It is also not confidential if the receiving side can show they already knew it before it was shared, or they received it lawfully from someone else who was not under a duty to keep it private.

Information is not confidential if it was developed independently without using the other side’s confidential information. Finally, if we are required to disclose something by a regulator, a court, an insurer, or similar official process, we may do so. Where we are allowed to, we will give the other side notice first and share only what we have to.

When this applies

This agreement applies from the date it is signed and covers all confidential information we share with each other from that point onwards, whether it is shared before a proposal is signed, during planning and pricing, or while work is on site.

Our duty to protect each other’s confidential information continues after our discussions end, or after any working relationship ends. That duty will last for the period we agree in writing. If we agree different periods for different types of information, for example security details versus pricing, we will set that out in writing as well.

Returning and deleting

If either of us asks, or when our discussions or work together end, we will return the other side’s confidential materials or securely destroy them. This includes copies, extracts, marked-up drawings, photos, notes, and downloaded files.

In practice, some information may sit in routine backups, email archives, or job records. We can keep what we reasonably need for normal business records, insurance, tax, warranty, or to show what was agreed and when. Anything kept like that stays confidential and is not pulled into use for another purpose. If you want something specific deleted, tell us what it is and where it was shared, and we will confirm what we have removed.

Who owns what

This agreement does not change who owns anything. Each side keeps ownership of its own ideas, methods, designs, documents, photos, and know-how, even if they are shared during discussions.

Sharing confidential information does not give the other side permission to copy it, publish it, or use it on another project. The only permission we both give each other under this agreement is to review the information and use it to decide whether to proceed, and if we do proceed, to plan and carry out the home building work we have agreed. Any wider use needs a separate written agreement.

If there is a leak

We both understand that if confidential information is leaked or misused, the harm is not always something money alone can put right. The harmed side can ask for an order to stop the leak or misuse, as well as seeking compensation for the loss.

If something goes wrong, we both agree to act quickly, share what we know, and take practical steps to limit the spread, for example removing access to links, requesting deletion from recipients, and securing any site copies.

Questions about this contract template

What should a contractor non-disclosure agreement include?

A contractor non-disclosure agreement usually defines what confidential information is, how it can be used, who it can be shared with, and what’s excluded. This template also covers returning and deleting materials, ownership of each side’s work, and what happens if there’s a leak.

What counts as confidential information on a building job?

Confidential information can include access and security details, drawings and surveys, photos, budgets, and day to day routines at the property. The same definition can cover the contractor’s pricing, supplier rates, sequencing, variation paperwork, and subcontractor contacts.

Does an NDA still apply if the client and contractor don’t go ahead?

The obligation starts from the date the agreement is signed and applies to information shared from that point onwards, including during early pricing and planning. The duty continues after discussions end for the period both sides agree in writing.

What information is not covered by an NDA?

Information isn’t confidential if it’s already public through no fault of the receiving side, or if the receiving side can show prior knowledge or lawful receipt from someone else. The exclusions also cover independently developed information and disclosures required by regulators, courts, or insurers.

What happens to drawings, photos, and documents after the job ends?

Either side can ask for confidential materials to be returned or securely destroyed, including copies, notes, and marked-up documents. Routine backups and business records can stay kept where reasonably needed, but the information remains confidential.

What can you do if confidential information is leaked?

The agreement recognises that money alone may not put things right, so the harmed side can ask for an order to stop misuse as well as compensation. Both sides also agree to act quickly to limit spread, including removing access to links and requesting deletion.
