Best NDA generators in the UK (2026)

Use a two-sided NDA when both sides still need to agree the words. On Contracts.io, Lex drafts from a sentence, you share one link, and both of you edit then e-signfirma elettronicaUna firma elettronica è qualsiasi modo elettronico di mostrare l’accordo a un documento, come un nome digitato, una firma disegnata o un clic.Altro nel glossario. Use a free Word file from Writford, AI Business Kit or the GOV.UK IPO examples when you only need a starting document to fill in.

Paid Word packs such as NDASafe suit specialist variants (employee, investor, M&A). Vordex builds a first draft around the disclosure, purpose, recipients, duration and UK legal system. Rocket Lawyer UK builds from a questionnaire inside a membership. None of those replace a two-sided room once the other side sends a mark-up.

This page is England & Wales first. Scotland and Northern Ireland are separate legal systems; Vordex and NDASafe say they let you pick among those systems. We list only facts taken from each vendor's own pages, checked 28 Oct 2026. If a claim is not on the page, we leave it out.

See NDAs explained, the NDA generator and NDA templates.

A template download gives you a Word or PDF file to fill in, email, and chase as "v4_final". A two-sided NDA keeps both parties on one shared version: they propose changes as redlines, Accept, Counter or Decline, then e-sign the same paper. That is the job Contracts.io is built for.

The downloaded file is a first draft in your hands. The other side opens it in Word, turns on Track Changes, and emails a new copy. Three rounds later nobody is sure which file is current. A two-sided room ends that thread: one link, one version history, one frozen signed copy.

GOV.UK's IPO examples, Writford, NDASafe and AI Business Kit all hand you a file. Vordex hands you an editable first draft to approve or negotiate. Rocket Lawyer UK builds the document in its own questionnaire. Contracts.io is the one in this list that puts both sides on the same link with Accept / Counter / Decline.

The NDA is still a contract either way. The difference is how you agree the words.

Contracts.io has a published Free plan at £0. Writford emails free England & Wales Word NDAs. AI Business Kit's NDA is free. The GOV.UK IPO examples are free ODT and PDF files. NDASafe is paid from £39. Vordex does not state a generator price on its NDA page. Rocket Lawyer UK markets a free NDA inside a membership.

What "free" actually means on each site:

• Contracts.io. Free £0, then paid plans from £15 a month. See /pricing. The other side never pays and never needs an account.
• Writford. Free to download and use commercially. No account. You enter a name, work email and organisation; they email an editable .docx.
• AI Business Kit. The NDA itself is free. Their NDA page says you sign up free with one click, with no card and no email verification, and download Word plus PDF. Other documents on that page are listed at £9, with an HR bundle at £29.
• GOV.UK Intellectual Property Office. Free example one-way and mutual NDAs, as ODT and PDF, under the Open Government LicencelicenzaUna licenza è il permesso di usare un lavoro in un modo concordato, senza togliere la titolarità a chi lo ha realizzato.Altro nel glossario. No sign-up.
• NDASafe. Not free. A single template is £39; the Core NDA Bundle of eight templates is £99.
• Vordex. The NDA generator page does not state a price. Their published pricing is for contract review, so we do not treat those figures as the generator's price.
• Rocket Lawyer UK. The NDA page is titled "MAKE YOUR FREE Non Disclosure Agreement". Completing documents sits inside their membership. Their pricing page was blocked from our fetch, so we do not print a monthly figure.

Free is not the same as two-sided. A free Word file still has to be emailed, edited and signed.

Contracts.io does: one share link, redlines, Accept / Counter / Decline, then e-sign. The other tools in this roundup give you a file or a first draft to take away. Writford, NDASafe, AI Business Kit and the GOV.UK IPO examples are downloads. Vordex describes an editable draft for approval or negotiation. Rocket Lawyer UK builds inside its own product.

That split is the whole wedge. If the other side will accept your paper as written, a filled-in Word file is enough. If they will change the purpose, the term, who may see the information, or the exclusions, you need one place where those edits live. Emailing "NDA_v3_JS_edits.docx" is how two people sign different text.

On Contracts.io the guest opens the link free, proposes a change, and signs the same version. See /features and your client redlined your contract.

Contracts.io is the two-sided option: Lex drafts, both sides edit one link, then e-sign. Writford and AI Business Kit are free UK Word downloads. NDASafe sells Word templates from £39. Vordex generates a first draft around the deal. The GOV.UK IPO examples are official one-way and mutual files. Rocket Lawyer UK builds from a questionnaire.

Match the tool to the job. If the other side will negotiate, pick a two-sided room. If you need a free file to fill in, pick Writford, AI Business Kit or the GOV.UK IPO examples. If you need a specialist Word variant, pick NDASafe. If you want a guided first draft, look at Vordex.

A working order:

1. Who is sharing? Mutual if both sides disclose; one-way if only one does. The IPO notes that a one-way NDA may need to be executed as a deed to make it enforceable — do not turn a one-way disclosure into a fake mutual NDA just to avoid a deed. Writford's one-way template carries a consideration recital so it can work as a simple contract.
2. Will they mark it up? If yes, a downloaded file becomes an email thread. Use a two-sided link.
3. Which UK legal system? England & Wales is the default on most of these pages. Vordex and NDASafe say you can choose Scotland or Northern Ireland. Rocket Lawyer UK asks whether Scots law or England and Wales should apply if a party is based in Scotland.
4. Do you need a specialist shape? Employee, investor, freelancer or M&A diligence NDAs are a different paper from a short commercial mutual. NDASafe sells those as separate Word templates. A general generator will not invent employment whistleblowing carve-outs unless you ask for them.
5. How will you sign? A simple NDA is commonly signed electronically. A deed still needs a witness who is physically present. See /law/england-and-wales.

Start from our NDA generator when you want Lex to draft, the other side to redline, and both of you to sign one version.

Because both parties agree on and edit the contract in one shared place. The purpose, exclusions, term and who may see the information stay on one version. Nobody signs v4_final while the other side signed v4_final_JS. That is our core job.

A typical Word thread looks like this: you fill the IPO or Writford blanks, email a .docx, they return a PDF of their paper, you copy clauses into a new file, and someone prints the wrong one. Each hop creates a new original. Two-sided editing keeps one original: every redline sits on the same page, every version is kept, and the signed copy is the one you both saw.

Lex drafts from a sentence ("a mutual NDAaccordo di riservatezza (NDA) reciprocoUn accordo di riservatezza (NDA) reciproco è un accordo di riservatezza in cui entrambe le parti condividono informazioni ed entrambe promettono di mantenerle private.Altro nel glossario with a studio we are pitching next week"). You edit. The other side opens the link free, with their own private Lex you cannot see. Accept, Counter or Decline. Then both of you e-sign one frozen version. The guest never pays.

That does not make a badly scoped NDA good. It does mean the words you both signed are the words you both edited. See /features and how to write a contract.

Use a mutual NDA when both sides will share confidential informationriservatezzaLa riservatezza è la promessa di mantenere private le informazioni condivise e di usarle solo per lo scopo concordato.Altro nel glossario. Use a one-way NDAaccordo di riservatezza (NDA) unilateraleUn accordo di riservatezza (NDA) unilaterale è un accordo di riservatezza in cui comunica informazioni una sola parte e solo l’altra è tenuta a mantenerle private.Altro nel glossario when only one side discloses. Partnership talks, agency pitches and joint projects are usually mutual. A founder pitching an investor, or a company briefing a supplier, is usually one-way. Match the paper to the information flow.

The IPO puts it the same way: one-way if only you are disclosing, mutual if both parties are. It also says that if the NDA is one-way only, it may need to be executed as a deedatto formale (deed)Un atto formale (deed) è un documento scritto formale che rispetta regole speciali di firma, comunemente usato quando una parte non riceve nulla in cambio.Altro nel glossario to make it enforceable, and that you should not make what should be a one-way agreement into an artificial mutual agreement.

A mutual NDA is often easier to get signed, because the terms bind both sides equally. Where only one side will realistically share anything, a one-way NDA is shorter and clearer. Lex will draft either if you say so in the sentence. NDAs explained walks through definition, exclusions, duration and who may see the information.

Yes, for a simple NDA. In England and Wales an electronic signature is admissible in evidence, and the Law Commission concluded it is capable in law of executing a document where the signer intends to authenticate it and any formalities are met. A deed still needs a witness who is physically present. Most commercial NDAs are simple contracts, not deeds.

The Electronic Communications Act 2000, s.7, makes electronic signatures admissible. The IPO's example one-way NDA is set out to be signed and delivered as a deed, with a witness block, because a one-way promise can lack considerationcorrispettivo (consideration)Il corrispettivo (consideration) è ciò che ciascuna parte dà o promette in cambio della promessa dell’altra in un contratto.Altro nel glossario. A mutual NDA usually has consideration each way: each side's promise of confidence.

On Contracts.io both sides e-sign one frozen version. See /law/england-and-wales, the e-signature page, and does an NDA need a wet-ink signature.
