Do I Need a Cookie Policy on My Website UK?

If you’re wondering do I need a cookie policy on my website UK, the answer depends on what your website actually uses.

Not every cookie requires consent, and not every website needs the same cookie banner. However, if your website uses cookies or similar technologies, you need to understand what they’re doing, provide visitors with the required information and obtain consent where an exception doesn’t apply.

This is particularly important because UK cookie rules have changed. The Data (Use and Access) Act 2025 introduced additional situations where certain technologies can be used without consent, and the Information Commissioner’s Office (ICO) published updated guidance in April 2026.

So if you’ve read older advice saying that every non-essential cookie always requires consent, it may now be out of date.

Here’s what you need to know when building your website.

Important: This article provides general information for people creating websites in the UK. It isn’t legal advice. Cookie and data-protection requirements depend on how your particular website operates, so check the latest ICO guidance where necessary.

What are cookies?

Cookies are small pieces of information that websites can store on a visitor’s device.

They can perform useful functions. For example, a website might use them to remember something a visitor has selected, keep a shopping basket working or understand how people use the site.

But cookies can also be used for tracking, profiling and advertising.

UK rules aren’t actually limited to traditional cookies. Other technologies that store information on or access information from a person’s device can also be covered. These can include tracking pixels, web storage, scripts, tags and some forms of fingerprinting.

For a beginner, the important question isn’t simply:

“Does my website use cookies?”

It’s:

“What technologies does my website use, and what are they doing?”

Does every website need a cookie policy?

Not necessarily in the way this question is often presented.

There isn’t a rule saying that every website must install an identical page called Cookie Policy.

What matters is whether your website uses cookies or other storage and access technologies, what they’re being used for and what information you’re required to give visitors.

This is why simply copying another website’s cookie policy isn’t a good solution.

Their website might use completely different plugins, analytics tools, advertising services and third-party integrations from yours.

You need to understand your own website.

Is cookie consent required in the UK?

Sometimes — but not for every cookie or storage technology.

Under the current UK rules, consent is generally required unless a relevant exception applies.

This distinction matters because UK law now includes several circumstances where storage or access technologies can be used without consent, provided the conditions for the particular exception are satisfied.

So the question isn’t simply:

“Does my website have cookies?”

It’s:

“What is each cookie or technology being used for, and does an exception apply?”

Which cookies don’t need consent?

Current UK rules contain five categories of exceptions covering certain storage and access technologies.

These relate to:

• transmitting a communication;
• providing a service that the user specifically requested where the technology is strictly necessary;
• certain statistical purposes;
• certain appearance or functionality preferences; and
• certain emergency-assistance situations involving location information.

For most people creating an ordinary website, the first four are likely to be the most relevant.

Let’s look at some practical examples.

Strictly necessary cookies

Some technologies are essential for providing something the visitor has specifically requested.

A familiar example could be technology necessary to keep items in an online shopping basket while somebody moves between pages.

If the website couldn’t provide the requested function without that technology, it may fall within the strictly necessary exception.

But “useful” isn’t automatically the same as “strictly necessary.”

You shouldn’t categorise something as necessary simply because you would prefer to use it.

Analytics and statistical cookies

This is one area where older cookie advice can now be misleading.

Changes to UK law introduced an exception for certain technologies used for statistical purposes.

This means some analytics uses may be possible without obtaining consent first, provided the specific conditions are met.

For example, the purpose must relate to collecting statistical information about how people use the service with a view to improving it. There are also requirements around providing clear information and giving people a simple and free way to object.

This does not mean:

“Analytics never needs consent anymore.”

Whether the exception applies depends on the particular technology, how it’s configured, what information is collected and what you do with that information.

That’s especially important if information is being used for additional purposes such as tracking people across services, profiling them or targeting advertising.

Appearance and functionality

The updated rules also contain an exception covering certain technologies used to enable or enhance the appearance or functionality of a service.

This could potentially cover things such as remembering preferences selected by a visitor.

Again, conditions apply.

The existence of an exception doesn’t mean you should classify every convenience feature as exempt. You need to understand the purpose of the technology and whether it actually satisfies the requirements.

What about advertising cookies?

Advertising and tracking deserve particular attention.

The fact that advertising helps pay for a website doesn’t automatically make advertising cookies strictly necessary for providing the website to the visitor.

Where a technology doesn’t qualify for one of the relevant exceptions, consent requirements continue to apply.

So if you plan to add advertising, remarketing pixels or other tracking technologies to your website, don’t assume that a basic cookie message saying “by continuing to use this website you accept cookies” is sufficient.

Find out exactly what the technology is doing.

Do I need cookie consent on my website?

If your website uses a technology for which consent is required, you need an appropriate way of obtaining that consent.

Consent needs to represent a genuine choice.

That means you shouldn’t load technologies requiring consent first and ask permission afterwards.

Visitors should also be able to understand what they’re agreeing to, and withdrawing consent should be as easy as giving it.

This is one reason cookie banners can become more complicated than they initially appear.

The purpose of the banner isn’t simply to make a legal-looking box appear at the bottom of the screen. It needs to reflect what the website actually does.

Cookie policy, cookie banner and cookie consent: what’s the difference?

These terms are often used interchangeably, but they’re not the same thing.

Cookie information or policy explains the technologies your website uses and provides relevant information about them.

A cookie banner or consent tool is an interface that can be used to provide information and, where necessary, collect or manage visitors’ choices.

Cookie consent is the visitor’s actual agreement to the relevant use of a technology where consent is required.

Installing a cookie banner doesn’t automatically mean your website complies with the rules.

For example, a banner isn’t much use if advertising cookies have already been loaded before the visitor gets a chance to choose.

Likewise, having a detailed cookie policy doesn’t remove the need to obtain consent where consent is legally required.

What about WordPress websites?

WordPress itself is only part of the picture.

The plugins, themes and third-party services you add can change what your website stores or accesses.

For example, you might add:

• an analytics service;
• an advertising platform;
• embedded videos;
• social media features;
• a contact form;
• an ecommerce system;
• booking software;
• live chat;
• marketing pixels; or
• other third-party integrations.

Each addition can potentially change your website’s cookie and privacy setup.

That’s why installing a cookie plugin on day one and then forgetting about it isn’t a great approach.

As your website changes, review what it uses.

What about Google Analytics?

Don’t automatically assume that installing Google Analytics means either “I definitely need consent” or “analytics is now exempt so I don’t need consent.”

Both statements are too simplistic.

The current UK statistical-purpose exception can apply to certain analytics uses, but conditions need to be satisfied.

The sensible approach is to look at your actual analytics configuration, what information is stored or accessed, what happens to the resulting data and whether your use meets the conditions of the relevant exception.

This is an area where checking current ICO guidance is more reliable than following an old WordPress tutorial.

Should I allow cookies on my website?

This People Also Ask question can be interpreted in two different ways.

If you’re a website owner, don’t start from the assumption that you should allow every cookie a plugin wants to use. Start by asking whether you actually need the technology.

A simpler website with fewer unnecessary trackers can also mean fewer things to manage.

If you’re a website visitor, whether you choose to allow optional cookies is your decision. A properly implemented consent mechanism should make clear what you’re being asked to agree to where consent is required.

For us as website builders, the useful principle is:

Don’t collect or track something simply because you can.

Know why you’re using it.

How do I find out what cookies my website uses?

This is the practical step many cookie-policy guides skip.

Before writing a cookie policy or configuring a consent tool, you need an inventory of what’s actually happening on your website.

Look at the services you’ve installed or connected, including your:

• WordPress plugins;
• analytics;
• advertising;
• embedded content;
• ecommerce tools;
• booking systems;
• email marketing tools;
• social media integrations; and
• other third-party scripts.

Cookie-scanning tools can also help identify technologies being used, although you shouldn’t blindly assume that an automated scan understands the legal purpose of every technology it finds.

Once you know what’s there, you can work out what each technology does and whether consent is required.

A simple cookie checklist for UK website owners

If you’re creating your first website, use this as a starting point:

1. Find out what your website uses.
Identify cookies and other storage or access technologies.

2. Work out what each one does.
Don’t categorise everything as “necessary” just because it’s convenient.

3. Check whether an exception applies.
The UK now has several exceptions, including certain statistical and functionality uses.

4. Give visitors the required information.
Explain what you’re using in clear language.

5. Obtain consent where it’s required.
Don’t use technologies requiring consent before you’ve obtained it.

6. Make choices genuine.
Where you’re relying on consent, visitors need an appropriate way to make and change their choices.

7. Review the setup when your website changes.
Adding a new analytics tool, advertising platform or plugin can change what your site does.

So, do I need a cookie policy on my website UK?

The most accurate answer is:

If your UK website uses cookies or similar technologies, you need to understand what they do and provide the information required by the rules. Whether you also need consent depends on the purpose of those technologies and whether a legal exception applies.

You don’t solve this simply by installing a cookie banner.

And you shouldn’t assume that every cookie needs consent, either.

The best starting point is to identify what your website actually uses. Then check those technologies against the ICO’s current guidance.
