Individuals have the right to be informed about the collection and use of their personal data. This is a key transparency requirement under the UK GDPR. Therefore, the child, young person or their family should be informed about what information about them is being shared, with whom and for what purpose. There are circumstances where you may not have to inform the child, young person or family that you intend to share information. For example, where it would seriously impair the achievement of the objectives of the processing (e.g. you would not need to inform the child, young person or family that you intend to share information for the purposes of safeguarding a child or young person where the family members are being investigated for neglect of that child or young person).
You should not routinely rely on exemptions; you should consider them on a case-by-case basis. You should justify and document your reasons for relying on an exemption. There is more information on exemptions on the ICO’s website Exemptions.
