What is the Data Protection Act 2018 (DPA 2018)?
The Data Protection Act 2018 (DPA 2018) is the United Kingdom’s primary data protection legislation, which governs how personal information is used, stored, and shared by organizations. It complements and implements the UK General Data Protection Regulation (UK GDPR), ensuring individuals’ privacy rights are protected while allowing lawful data processing for legitimate business purposes.
The Act replaced the Data Protection Act 1998 and came into force on 25 May 2018, aligning the UK’s data protection framework with modern digital realities such as online data sharing, cloud computing, and artificial intelligence.
Purpose of the DPA 2018
The DPA 2018 was designed to balance two objectives:
-
Protecting individual privacy — ensuring that personal data is collected and used fairly, transparently, and securely.
-
Enabling innovation and business operations — allowing organizations to process data responsibly for legitimate needs like customer service, analytics, or security.
It also sets out specific rules for:
-
Law enforcement processing (Part 3)
-
Intelligence services processing (Part 4)
-
General processing under UK GDPR (Part 2)
Key Principles of the Data Protection Act 2018
The DPA 2018 enshrines the same seven data protection principles outlined in the UK GDPR, which every organization must follow:
-
Lawfulness, fairness, and transparency – Data must be collected and processed legally and openly.
-
Purpose limitation – Data should be used only for specified and legitimate purposes.
-
Data minimization – Collect only the data that is necessary for the intended purpose.
-
Accuracy – Keep data accurate and up to date.
-
Storage limitation – Do not keep personal data longer than necessary.
-
Integrity and confidentiality – Secure data from unauthorized access or breaches.
-
Accountability – Organizations must demonstrate compliance through policies and documentation.
Who Does the DPA 2018 Apply To?
The Act applies to any organization or individual that processes personal data of individuals within the UK, including:
-
Private companies (e.g., retailers, tech firms, healthcare providers)
-
Public authorities (e.g., councils, schools, NHS bodies)
-
Charities and non-profits handling personal data
It also affects international organizations offering goods or services to UK residents or monitoring their behaviour online.
Rights of Individuals under DPA 2018
The DPA 2018 gives individuals significant control over their personal data, including:
-
Right to access their data
-
Right to rectification of inaccurate data
-
Right to erasure (“right to be forgotten”)
-
Right to restrict processing
-
Right to data portability
-
Right to object to certain uses of data
-
Rights related to automated decision-making and profiling
Enforcement and Penalties
The Information Commissioner’s Office (ICO) is the UK’s independent regulator responsible for enforcing the DPA 2018. Organizations that fail to comply can face severe consequences, including:
-
Fines up to £17.5 million or 4% of global annual turnover (whichever is higher)
-
Public enforcement actions and reputational damage
-
Legal claims from individuals affected by data breaches
