Website Legal Requirements in the UK: 2026 Compliance Checklist
15 August 2026
Ensure your UK website complies with 2026 rules: GDPR, cookie consent, accessibility, and more. This checklist covers every legal requirement.
Why Website Legal Requirements Matter for UK Businesses
Running a website in the UK isn't just about design and content—it's about legal compliance. Every site, from a small blog to a large e-commerce store, must follow specific laws designed to protect users and businesses. In 2026, the landscape is stricter than ever: the ICO is actively enforcing GDPR, the Equality Act 2010 mandates accessibility, and PECR governs cookies. Failing to meet these obligations can lead to fines of up to £17.5 million or 4% of annual turnover. Beyond penalties, compliance builds trust. A clear privacy policy and lawful cookie usage reassure visitors that their data is safe. This guide walks you through each requirement, step by step, so you can operate your website with confidence and avoid costly legal pitfalls.
UK GDPR and Data Protection Essentials
The UK GDPR, enshrined in law after Brexit and updated for 2026, applies to any website processing personal data of UK residents. You must have a lawful basis for collecting data, provide a transparent privacy policy, and inform users of their rights, including access, erasure, and portability. If you use analytics, email marketing, or user accounts, you're processing data. Ensure your privacy policy explains what you collect, why, and how long you keep it. Under UK GDPR, you must also report certain data breaches to the ICO within 72 hours. Consider appointing a Data Protection Officer if your core activities require large-scale monitoring. Regular Data Protection Impact Assessments (DPIAs) for high-risk processing are now standard practice. Ignoring these obligations can bring severe reputational damage and penalties.
Cookies and PECR: Getting Consent Right
In the UK, cookies and similar tracking technologies are regulated by the Privacy and Electronic Communications Regulations (PECR), enforced by the ICO. You must obtain explicit, informed consent before placing non-essential cookies—like those for analytics or advertising—on a user's device. A simple cookie banner isn't enough; it must clearly explain each category and allow users to choose to opt in or out. Essential cookies, such as those required for shopping carts or login sessions, are exempt. For compliance in 2026, your cookie notice should be as easy to dismiss as it is to accept, and you must keep records of consent. Avoid 'cookie walls' that force consent to access content, as the ICO views these as non-compliant. Review your cookie inventory regularly and update your banner accordingly.
Accessibility Obligations Under the Equality Act 2010
The Equality Act 2010 requires that your UK website be accessible to disabled users. This isn't just a nice-to-have; it's a legal duty. In 2026, BS EN 301 549 and WCAG 2.2 are the reference standards for digital accessibility. Your site should include features like keyboard navigation, alt text for images, sufficient colour contrast, and captioned video. Public sector sites must meet WCAG 2.2 AA, and while private sites are not automatically bound to WCAG, courts and the EHRC increasingly use it as a benchmark for reasonable adjustments. Failure to provide an accessible site could result in discrimination claims or enforcement action. To mitigate risk, conduct an accessibility audit, create an accessibility statement, and involve users with disabilities in testing. This not only meets legal requirements but also opens your brand to a wider audience.
Mandatory Company Information and Terms of Use
Every UK website must clearly display specific company information under the Companies Act 2006 and the Electronic Commerce (EC Directive) Regulations 2002. This includes your full company name, registration number, registered office address, and contact email address. If you sell online, you must also display your VAT number, delivery terms, and your return/refund policy in line with the Consumer Contracts Regulations. Ensure these details are easy to find—not buried in a PDF. Terms of use (or terms and conditions) set out the rules for using your site, disclaim liability where lawful, and protect intellectual property. For e-commerce, include clear pricing, an 'order confirmation' email, and the customer's right to cancel within 14 days. Non-compliance here can void contracts and attract Trading Standards queries.
FAQ
Yes. If you collect any personal data—even an email address—you must have a privacy policy under UK GDPR. It must explain what data you collect, why, how you process it, and the user's rights. The ICO can fine you for a missing or inadequate policy.
