What happened? The ICO’s latest cookie compliance action

In January 2025, the UK’s Information Commissioner’s Office (ICO) made it clear that cookie compliance isn’t something to overlook. They found that 134 out of 200 UK websites they checked had failed to meet cookie compliance standards, with some breaching key data protection laws.

This is part of the ICO’s ongoing broader push – See: ICO’s online tracking strategy for 2025 – aimed at ensuring the UK’s top 1000 websites adhere to compliant cookie practices, respecting users’ rights.

The ICO’s latest update highlights that many websites failed to meet legal standards for obtaining user consent for cookies, with cookie banners that were non-compliant with the UK’s strict requirements.

The ICO also updated the “consent or pay” guideline, which makes it clear that websites cannot require users to opt in to non-essential cookies in exchange for access to content, and published draft guidance on tracking people using storage and access technologies such as cookies and fingerprinting.

The ICO has made it clear that if left unaddressed, these violations could lead to further actions, including potential fines.

Key cookie compliance violations uncovered: What the ICO found in its latest review

In its review of 200 UK websites, the ICO identified several types of violations related to cookie compliance, underscoring the need for stricter adherence to the UK’s data privacy laws. Out of the 200 websites analyzed, 134 were found to be non-compliant.

Examples of cookie compliance violations found by the ICO

Lack of clear consent:
Many websites didn’t make it easy for users to understand what they were agreeing to or didn’t present users with an option to opt out of non-essential data processing. Some employ deceptive tactics, where consent banners were vague or hidden away, making it tough for visitors to make informed decisions.

Pre-ticked consent boxes:
Several websites used pre-ticked boxes or default settings, assuming consent for all cookies without giving users the option to easily opt out or customize their preferences.

Non-compliant cookie banners:
A significant number of websites had cookie notices that failed to meet legal requirements. These banners either lacked essential information about the types and purposes of cookies used, or didn’t provide users with genuine choices to refuse cookies.

No granularity in cookie preferences:
Many websites lacked granular consent controls, preventing users from opting in or out to specific categories of cookies (e.g., marketing, analytics or functional cookies), instead forcing users into an all-or-nothing choice.

Difficult to withdraw consent:
In some cases, once users consented to cookies, there was no clear or easy way for them to withdraw their consent later on, lacking clear or accessible mechanisms to change cookie preferences. This violates the ICO’s guidelines on ease of withdrawal.

New ICO cookie compliance guidelines: So what’s changed?

No major changes have been introduced to how cookie banners, consent management, and tracking practices should work. The updates mostly reaffirmed existing standards and clarified enforcement expectations, in a continued push for greater accountability and transparency in cookie consent practices. The main new element introduced is the stronger enforcement of the “consent or pay” rule.

The ICO has also ramped up its focus on ensuring the UK’s top 1,000 websites meet compliance standards, and it has signaled that violations will lead to stronger enforcement actions, including potential fines.

EXPERT’S OPINION
"The new ICO cookie compliance guidelines aren’t just a regulatory checklist – they reflect a shift in user expectations. People want transparency and control over their data more than ever. At Duga Digital, we've seen firsthand how implementing clear, user-friendly consent mechanisms not only ensures compliance but also builds trust with customers.”

Here’s a summary of what was reinforced or expanded:

Cookie compliance in the UK: old vs. new cookie guidelines (January 2025)

Stronger enforcement of existing principles

The ICO has highlighted that cookie compliance is a priority and has called attention to websites failing to meet key legal standards, specifically regarding cookie banners and consent mechanisms. While the principles themselves (e.g., valid consent, consent records’ retention limits, third-party transparency, etc.) haven’t fundamentally changed, the ICO has taken a stronger stance on enforcement.

Increased focus on large websites

There’s a heightened focus on the UK’s top 1000 websites. These websites are under increased scrutiny, as the ICO found significant violations when reviewing the top 200. The strategy includes scaling efforts to ensure these major websites comply with cookie regulations, which could lead to increased penalties for non-compliance.

Non-essential cookies

The new guidelines emphasize that consent for non-essential cookies (such as marketing cookies) can’t be made a condition for accessing content. This reinforces the idea that users shouldn’t be forced into consenting to optional cookies in exchange for services or content. It ensures that consent is truly informed and not forced.

Transparency and accountability

The ICO has continued to stress the need for greater transparency in how cookies are used, with more detailed explanations about third-party cookies and the specific purposes for which they collect user data. There is also an increased emphasis on record-keeping and accountability, urging companies to demonstrate that they are taking compliance seriously.

The ICO’s latest communications repeated the concept “meaningful choice” referring to users having real control over how their data is collected and used.

Quick overview: Key UK data privacy laws you need to know

To stay fully compliant, it’s essential to understand the key pieces of UK cookie law that govern cookie usage and personal data processing.

PECR (Privacy and Electronic Communications Regulations)

The PECR govern the use of cookies and other tracking technologies on UK websites. Similar to the EU’s ePrivacy Directive, PECR sets out clear rules that websites must follow when using cookies. The regulations require websites to obtain informed, specific and explicit consent before placing non-essential cookies, like tracking cookies, on internet users’ devices.

The Data Protection Act 2018 (UK GDPR)

The Data Protection Act 2018, also known as the UK GDPR, is the foundation of the UK’s privacy laws. It outlines how personal data should be processed, and while it’s very similar to the EU’s GDPR, it’s been adjusted to reflect post-Brexit UK regulations. Under the UK GDPR, organizations must lawfully, transparently, and fairly process personal data. It also gives individuals certain rights over their data, such as the right to access, erase, or restrict its processing.

UK GDPR vs. EU GDPR

While the UK GDPR is largely aligned with the EU GDPR, there are some key differences:
  • Geographical scope: UK GDPR applies to organizations that process the personal data of UK residents, while EU GDPR applies to those who handle the data of EU residents.
  • Supervisory authority: In the UK, the ICO oversees compliance, whereas, in the EU, it’s the Data Protection Authorities (DPAs) of individual member states.

Key points of the UK GDPR

  • Valid consent: Organizations must obtain informed, specific, and explicit consent from users before collecting personal data.
  • Data minimization: Only collect data necessary for your outlined specific purposes.
  • Right to access and deletion: Individuals have the right to access their data and request its deletion if it’s no longer needed.
  • Security: Organizations must implement appropriate technical and organizational measures to safeguard personal data.

The ICO (Information Commissioner’s Office) is the UK’s independent authority for upholding information rights and enforcing data privacy regulations, including cookie compliance. They issue warnings, enforce fines, and provide guidance to ensure organizations comply with the UK GDPR and the PECR.

What is PECR, and how does it relate to cookies?

The Privacy and Electronic Communications Regulations (PECR) govern cookie usage cookies on UK websites. PECR requires websites to obtain informed and explicit consent before placing optional cookies on users’ devices, such as those used for tracking or marketing purposes.

How is UK GDPR different from EU GDPR?

The UK GDPR is a UK-specific version of the EU GDPR that applies to organizations processing the personal data of UK residents. While the core principles are largely the same, the enforcement authority is the ICO in the UK, as opposed to Data Protection Authorities (DPAs) in EU member states.

No, essential cookies – such as those necessary for the website’s basic functionality – don’t require user consent, as per the ICO’s new guidelines. However, you must obtain explicit consent for non-essential cookies, like those used for analytics or marketing.

To ensure compliance with the ICO’s guidelines, your website must have clear, user-friendly cookie consent banners with equal prominence given to “Accept” and “Reject” options. Implement a Consent Management Platform (CMP) to manage user preferences and regularly audit your cookies. Update your privacy policy to reflect the types of cookies used and their purpose.

What penalties can I face for non-compliance?

Failure to comply with ICO guidelines may result in penalties, including fines. The severity of the fine depends on the nature and scope of the violations, so it’s essential to stay up-to-date with compliance requirements to avoid these risks.

The ICO has not yet imposed significant fines specifically for cookie compliance violations, but it has issued warnings and emphasized that it will consider fines if businesses do not improve their practices. For example, in November 2023, the ICO warned 53 UK websites about potential enforcement actions for non-compliance with cookie regulations (Source: ICO Press Release).

However, other European regulators, like the CNIL in France, have imposed large fines. For example, Amazon, Carrefour and Carrefour Bank were fined a combined €38 million for cookie consent violations in 2020.

The “consent or pay” principle means that websites cannot require users to opt in to non-essential cookies (like marketing cookies) as a condition to access content. Users must be given a genuine choice to opt in or opt out to cookies, and access to the website must not be conditional on accepting optional cookies.

However, other European regulators, like the CNIL in France, have imposed large fines. For example, Amazon, Carrefour and Carrefour Bank were fined a combined €38 million for cookie consent violations in 2020.

The ICO has reinforced the importance of transparency when it comes to third-party cookies. Websites must disclose third-party cookie usage, including which third parties are tracking users and for what purposes. This is part of a broader emphasis on transparency and accountability.

What changes were made in the ICO’s latest guidelines for large websites?

The ICO has increased its scrutiny of the UK’s top 1,000 websites, aiming to ensure these major sites comply with cookie regulations. Websites that fail to meet compliance may face increased penalties. This heightened focus stems from the ICO’s analysis of 200 websites, where a significant number were found to be non-compliant.

“Meaningful choice” refers to the user’s ability to make an informed decision about cookie consent, with clear, accessible options to opt in or opt out to cookies. Websites must enable real control over data collection, ensuring users are not coerced into consenting to optional cookies, and that consent is freely given.
