Tips for Businesses
Always clarify what someone means when they refer to a “DPA.” Check whether they mean the law (Data Protection Act 2018), a contract (data processing agreement), or an addendum. Train your team to understand common data protection terms so they can respond confidently and reduce the risk of compliance issues.
The word ‘DPA’ can get thrown around frequently in conversations about data protection law rules. Yet, depending on the context, it can refer to entirely different legal concepts. For businesses that process personal data or provide data processing services, understanding the meaning and uses of ‘DPA’ is essential, particularly when responding to customer queries or negotiating new agreements involving data protection provisions. For instance, your business may be asked about a ‘DPA’ or ‘the DPA’ when onboarding a new controller customer, renewing a contract or completing data protection due diligence questionnaires.
While these terms may seem familiar, you must understand their context and be fully clear on their meaning. This article explores a couple of the most common meanings of ‘DPA’ under UK data protection law and why your business should invest in compliance training so you are comfortable with data protection terminology in your everyday operations.
What is the UK Data Protection Law and Why Does it Matter?
The UK’s key data protection framework comprises the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018 (DPA 2018). Together, they set out essential rules regarding how businesses may use and safeguard personal data.
The UK GDPR provides broad principles, and the DPA 2018 builds on these by setting UK-specific rules. If your business processes personal data and falls within their scope, you must comply with these laws and be able to demonstrate compliance.
Can the Meaning of “DPA” Cause Confusion?
In real-world discussions on data protection issues, the term “DPA” can mean different things.
You might be asked typical questions like:
- Hey, can we grab a copy of your DPA?
- Can I check if you are DPA compliant?
- Does our older agreement need a new DPA because of the UK GDPR?
Sometimes, people refer to the DPA 2018 when they say DPA. Or, they might mean a data processing agreement. Your business should not guess – you should take the time to understand these uses to help avoid confusion and ensure compliance.

Common meanings of DPA may include the following:
The Data Protection Act 2018
This is the UK’s national data protection law, which works alongside the UK GDPR and fills in gaps that the GDPR does not cover. For example, it sets out rules for law enforcement and intelligence agencies and clarifies when exemptions apply.
If your business handles personal data, it must comply with both the DPA 2018 and the UK GDPR. This term can come up frequently when discussing your company’s compliance with data protection law rules.
A Data Processing Agreement
A DPA can also be a shorthand abbreviation for a ‘data processing agreement’, a contract between a controller and a processor that is mandatory under Article 28 of the UK GDPR.
Suppose your business acts as a processor (say, you host data on behalf of customers but have no control over that data). In that case, a data processing agreement is a legal requirement under the UK GDPR whenever your business acts as a processor for a controller. This agreement needs to include various information, e.g. the purpose of the processing, the type of data, how long it will be held, and the need for security measures to safeguard data.. It also needs to cover what happens to the data when the relationship ends.

This factsheet sets out how your business can become GDPR compliant.
Sometimes, your business may also hear the term ‘data processing addendum’. This tends to indicate a document you need to update or amend an existing contract for UK GDPR compliance, such as a commercial agreement that does not fully address UK GDPR data processing requirements. This addendum would set out each party’s data protection responsibilities and ensure the contract reflects mandatory legal obligations regarding data processing.
It is vital to ensure the addendum is appropriately drafted and executed, clearly works alongside the main agreement, and is incorporated correctly to become legally binding.
How Can Your Business Understand Its Obligations?
In the context of terminology such as DPA, it is important to take the time to ensure that staff who handle data protection queries understand common terminology. For example, failing to understand the meaning and context of data protection terminology can result in confusion and compliance omissions.
Example
As a practical example, a data processor is likely to receive various questions from data controllers about how they handle personal data. If a processor does not understand what DPA (or other key data protection terminology) means, this could send alarm bells and worry potential customers, impacting sales.
Your business is responsible for staff training and internal processes to help protect personal data. Your company and its staff need to know personal data and understand how it applies to their job roles and the wider business. Whether you have a privacy lead, legal advisor or data protection officer, your team should know where to turn if something goes wrong.
Training reduces risk, shows that your business takes data protection seriously, and demonstrates your accountability. As such, investing in data protection training can help protect your business from common data protection law misunderstandings and risks. If you need support with this, a data protection lawyer can help you.
Key Takeaways
Understanding what “DPA” means in data protection law is vital and will help your business handle common questions that arise, avoid confusion, and meet your legal requirements.
