What Are Cookies in Websites? UK Legal Rules Explained
Many UK business owners feel overwhelmed by cookie consent requirements, particularly as regulations in England and Wales become stricter.

You will discover practical steps to achieve UK GDPR and PECR compliance, empower website users, and reduce risk—using tools and templates designed for real businesses.

What Are Cookies in Websites and Why Do They Matter for UK Businesses?
Cookies are tiny text files placed on a visitor’s device when they land on your website. These files record data such as login status, preferences, shopping baskets, or browsing habits. Many UK businesses rely on cookies to offer personalised user experiences, track website analytics, manage secure sessions, and support digital marketing.
However, cookies also process personal data if they can identify users or monitor their behaviour. As a result, the law in England and Wales requires business owners to put privacy first: you must be transparent about what cookies you use, why you use them, and obtain consent for certain categories.
What Types of Website Cookies Are There? (Session, Persistent, Essential, Third-Party)
Understanding the different categories of cookies is essential for legal compliance and clear communication with your users:
- Session Cookies: These exist only while a user is active on your website and are deleted when the browser is closed. They enable features like keeping a user logged in or maintaining their basket during checkout.
- Persistent Cookies: These remain on the user’s device for a predetermined period. They remember choices or settings (like language preference) between visits.
- Essential (Strictly Necessary) Cookies: These are required for the basic operation of your website, such as processing payments or ensuring network security. Consent is not required for these but informing users is mandatory.
- Third-Party Cookies: Set by services other than your own website—such as analytics providers, advertising platforms, or social networks—to track user activity across different sites.
What Are Strictly Necessary vs Non-Essential Cookies?
Strictly necessary cookies power the basic functions of your website—without them, core services would break. You do not need consent to use these, but you should still disclose their use in your cookie policy. In contrast, non-essential cookies (for marketing, analytics, or personalisation) require proactive user consent before being set.
What Cookies Require Consent Under UK Law?
UK law is clear: only strictly necessary cookies are exempt from consent. For all other cookies—including those used for analytics, adverts, or social media integrations—you must secure explicit, informed permission from each user before storing them on a device.
Non-essential cookies often collect behavioural data. Regulators consider this data sensitive and require that users have genuine, clear choices. Relying on vague banners or implied consent does not meet the legal standard.
Do I Need Consent for Analytics or Third-Party Cookies?
The Information Commissioner’s Office (ICO) takes a firm view: almost all analytics and third-party cookies are non-essential and require user consent. A banner passively informing users that cookies are used, or using pre-ticked boxes and implied consent, fails to satisfy the law.
UK Cookie Consent Laws 2025: What Has Changed and What Stays the Same?
Your legal obligations for website cookies flow from the Privacy and Electronic Communications Regulations (PECR), the UK General Data Protection Regulation (UK GDPR), and the Data Protection Act 2018.
- What hasn’t changed: You must get consent for non-essential cookies, and giving users a real choice remains at the heart of legal compliance.
- 2025 updates: The ICO is now stricter about the detail required in your consent process. Consent should be specific by cookie category, not a single “accept all” option. You should keep a detailed record showing how you obtained consent and offer persistent, accessible ways for users to change their minds.
PECR, UK GDPR, and the Data Protection Act: The Legal Foundations
- PECR: Controls when you can set cookies and how you must obtain consent.
- UK GDPR: Applies when personal data is involved, requiring lawfulness, fairness, transparency, and respect for user rights.
- Data Protection Act 2018: Sets the enforcement mechanisms and complementary duties.

What Should a Compliant UK Cookie Banner Include?
A legally compliant cookie banner should be obvious, concise, and make it as easy to reject as to accept non-essential cookies. Users must not have to dig for details—controls should be intuitive and accessible.
Cookie Banner Requirements and Best Practice Checklist
- Use clear, plain language—avoid jargon.
- Never use pre-ticked consent boxes.
- Make “Reject” and “Accept” options equally prominent.
- Give granular controls by category (like ‘analytics’, ‘marketing’, ‘functional’).
- Keep a visible link to your cookie policy and preference centre on every page.
- Ensure no cookies (other than strictly necessary) are set before gaining positive consent.

- Implement a Consent Banner: Use a banner that meets UK legal standards and gives a real choice.

Common Cookie Compliance Mistakes to Avoid
| Mistake | Why It’s a Problem | How to Avoid It |
|---|---|---|
| Using implied consent or pre-ticked boxes | Fails to meet UK standards for valid consent | Always require a clear, affirmative user action |
| Not updating the cookie policy for new tools | Outdated information creates legal risk | Review your policy after any website change |
| Omitting instructions for consent withdrawal | Users must have easy opt-out options | Include clear, accessible withdrawal mechanisms |
How Can Users Change or Withdraw Cookie Consent After Accepting?
Your website must always provide a simple, accessible way for users to change or withdraw their cookie choices at any time. The standard is clear: a prominent link or button—ideally in your page footer—should allow users to review and manage their preferences without contacting your business directly.
