How to Draft a Privacy Policy in the UK

If you collect any personal data from customers, employees, or website visitors, you need a privacy policy — and in the UK, that is not optional. Knowing how to draft a privacy policy in the UK means understanding what UK GDPR and the Data Protection Act 2018 actually require, not just copying a template from another website. A compliant privacy policy must tell people who you are, what data you collect, why you collect it, how long you keep it, and what rights they have. Get any of those wrong and you risk ICO enforcement action, fines, or losing customer trust. This guide walks you through every section you need to include, in plain language, so you can produce a policy that holds up — whether you are a sole trader, a startup, or an established SME. We also flag where the complexity increases and when it is worth getting a solicitor involved rather than going it alone.

Why this matters

Most founders either skip the privacy policy entirely, paste one from a US website, or use a generic template that does not reflect how their business actually handles data. None of those options protect you. UK GDPR requires your policy to be specific, accurate, and kept up to date. If your policy says you do not share data with third parties but you use Google Analytics, Mailchimp, or a CRM, you are already non-compliant. The real pain here is not knowing what the law actually requires versus what looks like it might be enough. This page closes that gap.

The Atornee approach

Atornee lets you generate a UK-specific privacy policy by answering plain-English questions about your business — what data you collect, who you share it with, and how long you keep it. It maps your answers to UK GDPR requirements and produces a structured, editable document you can publish or hand to a solicitor for review. You are not getting a generic template. You are getting a document built around your actual data practices, with the legal structure already in place. For straightforward businesses, that is often enough. For anything involving sensitive data categories or complex data sharing arrangements, Atornee flags where you should get specialist advice.

A direct route to generate a UK-compliant privacy policy through Atornee, tailored to your specific data practices

Before you sign checklist

1
1. List every type of personal data your business collects — names, emails, payment details, IP addresses, cookies, anything
2
2. Identify your lawful basis for processing each data type under UK GDPR Article 6 (and Article 9 if you handle special category data)
3
3. Map every third party you share data with, including analytics tools, email platforms, payment processors, and cloud storage providers
4
4. Confirm where your data is stored and whether any of it leaves the UK or EEA, as international transfers require additional disclosure
5
5. Set your retention periods — how long you keep each type of data and why — and document this in your policy
6
6. Draft or generate your policy covering all required sections: identity of controller, data collected, purposes, lawful bases, retention, third parties, data subject rights, and contact details
7
7. Publish the policy where users can find it before submitting any data, and set a reminder to review it whenever your data practices change

FAQ

Is a privacy policy legally required in the UK?

Yes, if you collect personal data from individuals, UK GDPR requires you to provide a privacy notice. This applies to almost every business with a website, an email list, or employees. The ICO can take enforcement action against businesses that fail to provide adequate transparency about how they use personal data.

What must a UK privacy policy include?

Under UK GDPR Articles 13 and 14, your policy must include: the identity and contact details of the data controller, the purposes and lawful bases for processing, any third parties you share data with, international transfer details if applicable, retention periods, and a full list of data subject rights including the right to access, erasure, and complaint to the ICO.

Can I use a free privacy policy template?

You can use a template as a starting point, but a generic template is unlikely to accurately reflect your actual data practices. UK GDPR requires your policy to be specific to how your business operates. A policy that does not match your real data flows is not compliant, even if it looks professional. Always customise any template to your actual situation.

Do I need a separate cookie policy?

Strictly speaking, cookie information can sit within your privacy policy or in a separate cookie policy — both approaches are acceptable. What matters is that users are informed about cookies before they are set, which typically means a cookie consent banner linked to your policy. If you use non-essential cookies, you need explicit consent under PECR as well as UK GDPR.

When should I get a solicitor to review my privacy policy?

If your business handles special category data (health, biometric, financial, or children's data), transfers data outside the UK, uses automated decision-making, or operates in a regulated sector, you should get a solicitor to review your policy rather than relying on a template or AI-generated document alone. The stakes are higher and the compliance requirements are more detailed.

How often should I update my privacy policy?

You should review your privacy policy whenever your data practices change — new tools, new third-party integrations, new data types, or changes in how long you retain data. As a minimum, an annual review is sensible. If you update the policy materially, you should notify existing users and, where required, re-obtain consent.
