UK Website Legal Requirements 2026: What You Actually Need
Privacy policy. Cookie banner. Terms and conditions. You have been told you need all three — but do you? And if so, what exactly must they say? This is the plain English answer, covering every UK law that applies to business websites in 2026.
The short answer
Every UK website needs these three things
Privacy Policy
UK GDPR / Data Protection Act 2018
If you collect any personal data — which includes contact forms, analytics, and cookies
Cookie Consent Banner
PECR (Privacy and Electronic Communications Regulations)
If your site uses non-essential cookies — which includes Google Analytics, Facebook Pixel, and most marketing scripts
Terms & Conditions
Consumer Contracts Regulations 2013 / Consumer Rights Act 2015
Not mandated by a single law, but legally essential in practice — especially for ecommerce
Privacy Policy
Required under: UK GDPR & Data Protection Act 2018
A privacy policy is legally required on any UK website that collects personal data. Under UK GDPR, personal data includes far more than names and email addresses — it covers IP addresses, cookie identifiers, location data, and any information that could be used to identify a living individual.
In practical terms: if your site has a contact form, uses Google Analytics, or loads any third-party script that sets a cookie, you are collecting personal data and you need a privacy policy. That covers almost every business website in the UK.
What a UK privacy policy must include
Your identity and contact details
Full legal name, address, email
What data you collect
Names, emails, IPs, cookies, etc.
Lawful basis for processing
Consent, legitimate interest, contract, legal obligation
How long you retain data
Specific retention periods per data type
Third-party sharing
Email platforms, analytics, payment processors
International transfers
If data leaves the UK (e.g. US-hosted services)
User rights
Access, erasure, rectification, objection, portability
How to complain
Right to contact the ICO
Common mistake
Copying a privacy policy from another website is a breach of copyright and almost certainly produces a non-compliant document, since the data you collect will differ from theirs. The ICO provides a free privacy policy generator at ico.org.uk — use it as a starting point, then customise it to reflect exactly what your site does.
Cookie Consent Banner
Required under: PECR (Privacy and Electronic Communications Regulations)
The UK cookie law (PECR) requires you to obtain prior, informed consent before placing any non-essential cookies on a visitor's device. The consent must be active — a pre-ticked box or continuing to use the site does not count.
Which cookies need consent?
| Cookie type | Examples | Consent needed? |
|---|---|---|
| Strictly necessary | Login session, shopping cart, CSRF tokens | No |
| Analytics | Google Analytics, Hotjar, Mixpanel | Yes |
| Marketing / tracking | Facebook Pixel, Google Ads, LinkedIn Insight | Yes |
| Preferences | Language, font size, remembered form fields | Yes (unless essential) |
| Third-party embeds | YouTube videos, Google Maps, Calendly | Yes |
What a valid cookie banner must do
- Appear before any non-essential cookies are set — not after
- Give users a genuine choice to accept or reject — the "reject" option must be as easy to find as "accept"
- Explain what categories of cookies you use and why
- Allow users to change their preferences at any time
- Record and store consent so you can prove it was given
- Not use dark patterns — no pre-ticked boxes, no guilt-tripping language
ICO enforcement
The ICO has been increasingly active on cookie compliance. In 2023 it issued an enforcement notice against a major UK publisher for non-compliant consent. The ICO's own guidance states that banners which make it harder to reject than accept are non-compliant — a design decision, not a legal grey area.
Terms & Conditions
Required under: Consumer Contracts Regulations 2013 & Consumer Rights Act 2015
No single UK law says "you must have terms and conditions on your website." But multiple laws together make T&Cs legally essential — particularly if you sell goods, services, or digital products online. Without them, you have no written basis to enforce your own policies, and customers retain broader rights than you may expect.

Companies Act 2006 Disclosures
Required for: all UK limited companies
If your business is a UK limited company, the Companies Act 2006 requires specific information to appear on your website — not buried in a footer page, but accessible from the site. This is one of the most commonly overlooked requirements.
Mandatory disclosures for UK Ltd companies
Registered company name
Full legal name as registered at Companies House
Company registration number
The 8-digit number from Companies House
Registered office address
Not necessarily your trading address
Country of registration
e.g. "Registered in England and Wales"
VAT number
If VAT-registered — also required on invoices
ICO registration number
If processing personal data (most businesses)
These disclosures must also appear on all business emails and letters under the Companies Act.
Sector-Specific Legal Requirements
Regulated industries carry additional website obligations beyond the baseline UK GDPR and PECR requirements. These are some of the most commonly missed — and the most likely to attract a regulator's attention.
Law Firms & Solicitors
Regulator: SRA
- →Price and service transparency pages (SRA Transparency Rules)
- →Complaints procedure published on the site
- →Professional indemnity insurance disclosure
- →SRA authorisation number displayed
Dental Practices
Regulator: GDC / CQC

- →Complaints and patient rights information

- →"Your home may be repossessed" risk warnings where applicable

What if Your Current Website Is Not Compliant?
Most UK business websites built before 2018 were built before UK GDPR came into force. Many sites built since then still lack a compliant cookie banner, correctly structured privacy policy, or the right Companies Act disclosures. Non-compliance is very common — but it is not a defence if the ICO investigates.
The good news is that legal compliance does not require a full website rebuild. In most cases it means adding or updating specific pages and implementing a cookie consent management platform (CMP) such as Cookiebot, CookieYes, or Usercentrics.
If your site is old enough to have compliance gaps, it may also have performance, SEO, or design issues worth addressing at the same time. Our website redesign service includes a full legal compliance review as part of the discovery process.
