NDA for the Games Industry UK: Protecting Game Concepts, Source Code and Creative IP

UK game developers, publishers, studios and freelancers share sensitive game concepts, source code and creative IP before formal agreements are signed. This guide explains when a UK games industry NDA is needed, what it must cover, and which template to use.

The UK video games industry is one of the largest in Europe — home to studios including Rockstar North, Rare, Media Molecule and Codemasters, and a large and globally competitive independent developer community — and it operates in a market where creative IP is the primary commercial asset. Game concepts, narrative frameworks, gameplay mechanics and proprietary development technology are all commercially sensitive before they are disclosed in a pitch, a collaboration or a development deal. An NDA is the standard mechanism for protecting this information during the pre-contractual phase — from first publisher pitch through to formal development agreement or IP assignment.

When UK games industry parties need an NDA

An NDA is appropriate at the following stages of a UK games project:

Publisher pitches and development deal discussions: before a developer shares a game concept, story bible, character designs, gameplay demonstration or prototype with a publisher or platform holder evaluating a potential development agreement.
Investor and funding discussions: before sharing a business plan, IP valuation, projected development budget or financial forecasts with potential investors, grant bodies or funding partners.
Contractor and freelancer hiring: before sharing source code, technical design documents, art assets or game engine modifications with external developers, artists, sound designers, writers or QA testers.
Platform and console certification: before sharing technical integration documentation, SDK usage or unreleased game builds with platform holders in connection with console certification or early access programmes.
Co-development and studio partnerships: before sharing proprietary technology, engine code or game design documents with another studio in a co-development or work-for-hire arrangement.
Marketing agency and PR engagements: before sharing unreleased game content, launch materials, key art or announcement details with external marketing agencies, PR firms or social media partners before the game's public announcement.
Middleware and technology licensing: before sharing technical integration requirements or proprietary engine details with middleware providers, tool developers or technology licensing partners.

What a games industry NDA must cover

A generic commercial NDA may miss the specific risks in games industry relationships. A UK games NDA should include:

Dual-category definition of confidential information: creative IP (game concepts, story bibles, character designs, gameplay mechanics, level design documents, script and concept art) and technical development material (source code, engine modifications, proprietary pipelines, build files and performance approaches) must both be expressly named.
Purpose restriction and independent development prohibition: use of disclosed information must be expressly limited to evaluating or executing the stated deal or engagement, with an explicit prohibition on developing or commissioning any game that uses the core concepts, mechanics or narrative framework disclosed.
Prototype and build file provisions: playable builds, executable prototypes, screenshots and recordings taken during evaluation must be covered as confidential information; the NDA should require their deletion after evaluation and prohibit reverse engineering.
IP ownership clarity: the NDA should record whether any bespoke materials created during the evaluation period (such as pitch-specific art or documents prepared for a publishing proposal) remain the developer's property pending any formal deal.
Trade secret protection for proprietary technology: bespoke game engine components, proprietary rendering techniques and custom development tools should be identified as trade secrets under the Trade Secrets (Enforcement, etc.) Regulations 2018, with a survival clause providing indefinite protection.
Return or deletion of materials: all disclosed materials — design documents, concept art, build files and access credentials — must be returned or securely deleted at the end of the evaluation period or on termination of discussions.

Copyright and idea protection in the games industry

Copyright in the games industry protects the specific expression of creative work — code, artwork, dialogue, music and sound — but not the underlying ideas, mechanics or concepts. This creates a protection gap at the pitch and pre-production stage that an NDA is specifically designed to fill:

Game concepts and mechanics are ideas: a gameplay mechanic, however innovative, does not attract copyright as an idea — it only becomes protected once expressed in code or detailed design documentation. Before that point, an NDA is the only contractual protection available.
Genre and premise: a genre-mashup premise or narrative concept has no copyright protection as an idea. An NDA prevents a publisher or investor who receives a concept pitch from using that information to commission a competing project from another developer.
World-building and lore: the specific expression of a world-building document attracts copyright protection, but the underlying world concept does not. An NDA protects both the document and the ideas it contains.
Characters: a character design expressed in concept art attracts copyright; the underlying character concept does not. An NDA protects both during the pre-production and pitch phase.

Which NDASafe template to use

The right template depends on the structure of the games industry relationship:

One-Way NDA, Disclosing (£29): the default for developer-to-publisher pitches where only the developer is sharing sensitive game concept, creative IP and technical information.
Mutual NDA (£29): use for co-development arrangements, technical partnerships and publisher relationships where both parties are sharing sensitive information — the developer's IP and the publisher's commercial strategy, platform data or technology.
Freelancer NDA (£29): use for sole-trader developers, artists, writers, QA testers and sound designers engaged as independent contractors — includes the IR35 acknowledgement clause relevant to self-employed contractors.
Complete NDA Bundle (£79): all eight NDA variants. Suitable for studios and publishers managing a range of developer, investor, contractor, platform holder and marketing agency relationships simultaneously.

Step by step

1
Sign before sharing any game concept, story bible or prototype
The most commercially significant moment for a UK game developer is the pitch stage — sharing a game concept, character design sheet, story bible, vertical slice or pre-alpha prototype with a potential publisher, investor or platform holder. This material represents the creative core of the project and has no automatic legal protection as an idea. The NDA must be signed before any substantive pitch material is shared — before the developer presents the concept presentation, before the publisher receives the story bible, and before any playable prototype is demonstrated. Waiting until after the pitch has been delivered leaves the core concept unprotected at the point of greatest exposure.
2
Define confidential information to cover both creative IP and technical development material
A games industry NDA needs a definition broad enough to cover two distinct categories. Creative IP: game concept descriptions and pitch documents, story and narrative frameworks, world-building documents, character designs and concepts, gameplay mechanic descriptions, level design documents, pre-production art and concept art, script and dialogue, and sound design direction. Technical development material: source code, game engine modifications, proprietary tools and pipelines, build configurations, technical design documents, asset pipelines and compression schemes, performance optimisation approaches, and network architecture for multiplayer systems. Both categories can qualify as trade secrets under the Trade Secrets (Enforcement, etc.) Regulations 2018 where they are not publicly known and have commercial value.
3
Include restrictions on independent development using disclosed concepts
A purpose restriction preventing independent development or use of disclosed concepts is the most important substantive protection in a games NDA. The receiving party — whether a publisher, investor, platform holder or development partner — must be prohibited from: using disclosed game concepts to develop or commission a competing title; using disclosed narrative frameworks, world-building structures or character concepts in any project without authorisation; and using technical information shared (engine modifications, proprietary tools, performance approaches) in any other project. In practice, this means that a publisher who receives and rejects a developer's pitch cannot then commission a similar title from another studio using the core concept — if that concept was shared under an NDA.
4
Address prototype builds, build files and evaluation access
Sharing a playable prototype, vertical slice or alpha build creates a specific category of risk: the receiving party has access to working game code, asset files and design data in executable form. The NDA should address this directly: specifying that build files, executable prototypes and any screenshots or recordings taken during evaluation are confidential information; prohibiting reverse engineering of any shared build or technical file; requiring deletion of build files at the end of the evaluation period; and restricting any recording or external disclosure of prototype content. Platform holders and publishers who evaluate large numbers of pitches often have their own NDAs — review these carefully before signing, as they may include restrictions on future development in the same genre or using the same mechanics.
5
Match duration to the game's development and release lifecycle
Game development timelines are long — typical commercial game projects run two to five years from concept to release. Duration should reflect this: game concepts, story bibles and pre-production creative materials — five years from disclosure, covering the full development cycle plus a reasonable tail after any released competing title; source code and technical development materials — three years from disclosure or twelve months after the game's commercial release, whichever is later; publisher commercial information, funding terms and platform agreements — two to three years from disclosure; proprietary engine components and middleware — indefinite, with a trade secret survival clause. Where the project is cancelled or a deal is not done, all disclosed materials should be returned or securely deleted.

Frequently asked questions

Why does the UK games industry need a dedicated NDA?

Game concepts, narrative frameworks, gameplay mechanics and world-building are commercially sensitive before any formal agreement is signed. At the early pitch stage — before a publisher agreement, development deal or investment term sheet — developers share game concepts, character designs, story bibles, gameplay systems and prototype builds that represent years of creative development. Copyright does not protect ideas, only their specific expression — a game concept, however distinctive, has no automatic legal protection as an idea. An NDA fills this gap, imposing a binding obligation of confidence on anyone who receives the concept at the pitch or pre-production stage. The UK games industry is highly competitive; concept-stage NDA protection is standard practice in mainstream publishing relationships and increasingly expected in indie funding discussions.

What type of NDA is appropriate for a game developer pitching to a publisher?

For a developer pitching a game concept to a publisher, a one-way NDA (disclosing) is appropriate — the developer is sharing sensitive creative and technical information; the publisher is evaluating, not reciprocally disclosing its own development IP. A mutual NDA is the right choice when the publisher also shares non-public information — internal production targets, upcoming platform agreements, funding appetite or development tools that the publisher considers confidential. Where a publisher is commissioning a developer as a contractor to build a defined game or component, the Freelancer NDA (for sole traders and small studios) or the Mutual NDA with appropriate IP assignment provisions is the right starting point.

Does an NDA protect a game concept, or is copyright sufficient?

Copyright does not protect ideas — only the specific expression of those ideas in a fixed form. A game mechanic, a genre mashup concept, a narrative premise or a world-building framework is an idea; it does not attract copyright protection until it is expressed in code, artwork, script or another fixed form. An NDA fills this gap by imposing a binding obligation of confidence on anyone to whom the concept is disclosed, protecting the idea itself during the critical pre-production and pitch phase. Once a game is published, copyright protects the specific assets — code, artwork, dialogue and music. During development and at the pitch stage, an NDA is the primary protection for the underlying creative IP.

What IP provisions should a games NDA address alongside confidentiality?

A standalone NDA focuses on confidentiality — it prevents disclosure, not independent development or copying. For game development relationships where work is being created, a separate IP assignment or work-for-hire provision is also needed. Key IP issues to address in the broader agreement include: who owns bespoke game engine code or tools developed during the project; whether the developer retains or assigns rights to any reusable assets, character designs or gameplay systems; what happens to IP if the project is cancelled; and how the parties handle improvements or derivatives of shared technology. The NDA governs what information must be kept secret; the IP assignment provision determines who owns what is created.

How long should a games industry NDA last?

Duration depends on the type of information shared. Pre-production creative concepts, game pitches and story bibles — three to five years, reflecting the typical development lifecycle; concepts not taken forward may remain sensitive while the developer independently develops them or approaches other publishers. Source code and development tools — three years from disclosure or until the game is publicly released, whichever is later. Publisher commercial information — funding terms, platform deals, release schedules — two to three years from disclosure. Proprietary game engine components and middleware — indefinite, with a trade secret survival clause under the Trade Secrets (Enforcement, etc.) Regulations 2018.
