About

The GOV.UK Prototype Kit provides a simple way to make interactive prototypes that look like pages on GOV.UK. These prototypes can be used to show ideas to people you work with, and to do user research

Support

The GOV.UK Prototype Kit is currently maintained by the GOV.UK Design System team, who can only provide limited support.

If you’ve got a question, idea or suggestion, share with the community of users on the #govuk-prototype-kit channel on cross-government Slack.

We cannot give general advice to the public. We do not have access to information about you held by government departments.

For other enquiries, use the contact form on GOV.UK.

Principles

The GOV.UK Prototype Kit:

  • is designed for prototyping, not for production code
  • requires minimal skills to get started: HTML, CSS
  • should be fully documented in a way that is accessible to the target audience
  • makes use of GOV.UK Frontend
  • allows for server-side code
  • can be extended - for example using NPM to install a module, access datastores, etc
  • makes it easy to share prototypes with others online

Privacy

You must protect user privacy at all times, even when using prototypes. Prototypes made with the kit look like GOV.UK, but do not have the same security provisions. Always make sure you are handling user data appropriately.

The kit is not a production framework

Things made with the kit may look like GOV.UK, but do not have production code and likely aren't fully accessible. Don't use the kit as a base for a production service.
