There is an appendix which contains an invaluable Keeling Schedule; that is, the original EU Regulation with the amendments made to it by the Data Protection, Privacy and Electronic Communications (Amendments etc) (EU Exit) Regulations 2019 (as amended by the Data Protection, Privacy and Electronic Communications (Amendments etc) (EU Exit) Regulations 2020).

Structure & Layout

Within each chapter there are numbered paragraphs on a range of topics relevant to the chapter in question.


The main tool is the Keeling Schedule which helps to identify the ways in which the UK GDPR differs from the GDPR. However, throughout the text there are no tools as such but confirmation where appropriate that the EU rules are replaced in the same form in the UK GDPR or explanations of where UK GDPR now differs from the rules in the EU.

Clarity & readability

The writing is clear. For example, Chapter 2 starts:

“Chapter II sets out the principles of the UK GDPR, including the rules around consent and processing special categories of personal data. There are few differences when compared to Chapter II of the GDPR and the principles are identical.”

It is a shame that there are no examples in the text of how a particular person’s position might have changed between GDPR and UK GDPR. Trust practitioners were advised by STEP that UK GDPR could feasibly apply differently than previously and apply on either a trust by trust basis or a trustee by trustee basis, which has a bearing on the cost of the data protection fees.

Relevance to practitioners

As a summary of the law of UK GDPR and how it differs from GDPR this text is of relevance to every practitioner. It is a useful source of the law. It provides clear explanations of the differences between GDPR and UK GDPR. Given the consequences for individuals and firms of incorrectly applying the law, this is an essential text.
