This documentation provides information about languages and frameworks that are approved for use when developing technology solutions for UKHSA.

How to read the guidelines

The following terms are used throughout this guidance to indicate the strength of each requirement.
These are adapted from RFC 2119 and contextualised for UKHSA:

  • MUST: This requirement is mandatory. It applies universally and must be followed without exception unless formally approved.
  • MUST NOT: This action is explicitly prohibited. It must not be taken under any circumstances unless an approved exception is in place.
  • SHOULD: This is a strong recommendation. There may be valid reasons to deviate, but the implications must be understood, justified and documented.
  • SHOULD NOT: This is a strong recommendation against a practice. Exceptions may exist, but they must be carefully considered, justified and documented.
  • MAY: This is an optional practice or recommendation. Teams may choose to adopt it based on context, value or preference.
