Do Small UK Businesses Need Cookie Banners?
Oct 17, 2025
Your guide to UK cookie laws, GDPR, and what compliance really means for small websites.
The Short Answer
Yes! If your website uses cookies that track visitors, collect analytics data, or support advertising, you must show a cookie banner.
There’s no exemption for small businesses under UK GDPR or PECR (the Privacy and Electronic Communications Regulations). What matters is the data, not your size.
Why Cookie Banners Are Required
Even the smallest business websites collect data; often without realising it.
If you use Google Analytics, Facebook Pixel, YouTube embeds, live chat, remarketing tags or even just load Google Fonts, those tools place cookies that store user information.
Under UK GDPR and PECR, you must:
Inform visitors what cookies you use and why.
Ask for consent before setting any non-essential cookies.
Allow withdrawal of consent as easily as it was given.
Only strictly necessary cookies (those essential to site function) are exempt.
Examples of Non-Compliant Setups
If any of the following apply to your site, your banner probably isn’t compliant:
Cookies are set before consent (e.g. Analytics runs on first load).
The banner says “By using this site you agree…” (implied consent).
Only an “Accept” button is shown (no “Reject” or “Manage”).
Scripts before fire users set their consent preferences.
Modern compliance means no tracking until consent, and many DIY banners don’t handle this correctly.
Why Size Doesn’t Matter
Many UK small businesses assume privacy laws target only big tech companies.
In truth, the ICO (Information Commissioner’s Office) can investigate any business following a user complaint.
Even a one-page brochure site could be investigated if cookies track visitors without consent.
Compliance isn’t about avoiding fines, it’s about trust and transparency.
When Cookie Banners Break Your Google Tracking
A poorly configured cookie banner doesn’t just risk non-compliance, it can also break your analytics entirely.
If Google Analytics, Google Ads, or Tag Manager scripts are blocked before consent and never re-trigger properly, you lose data on every visitor who clicks “Accept.”
Conversely, if they run too early, you risk breaching UK GDPR and PECR because data is sent before consent.
Both scenarios hurt your business:
You can’t see where your visitors come from or which channels convert.
Conversion tracking in Google Ads becomes unreliable.
Consent Mode (Google’s built-in privacy tool) doesn’t function correctly without proper setup.
When configured correctly, Consent Mode adjusts how Google tags behave:
Before consent: sends anonymous pings with no personal data.
After consent: resumes normal tracking seamlessly.
This balance allows you to stay compliant without sacrificing marketing insights. But only if your banner is properly integrated with Google Tag Manager and Consent Mode V2.
That’s why CookieChest installations include full testing to ensure analytics scripts, consent events, and ad tracking all fire exactly when they should, and never when they shouldn’t.
Benefits of Getting It Right
A compliant cookie banner isn’t just a legal tick-box. It’s good business sense.

FAQ
Do small businesses really need a cookie banner in the UK?
Yes. If your site uses any non-essential cookies, such as Google Analytics or ads, you need user consent under PECR and UK GDPR.
Are free cookie banner plugins enough?
Usually not. Most free plugins still load cookies before consent, which makes them non-compliant.
Can I disable cookies instead?
You can remove tracking scripts, but this limits analytics and marketing insight. A compliant banner lets you keep tracking responsibly.
What’s the penalty for non-compliance?
The ICO can issue fines, but reputational damage is often worse. Users trust businesses that respect their privacy.
Does CookieChest work outside the UK?
Yes. CookieChest adapts automatically for EU and international visitors based on local privacy laws.
Key Takeaway
If your website uses any tracking tools, you need a cookie banner that meets UK GDPR and PECR standards.
Small business or not, you’re still responsible for protecting user privacy./
