Compliance • Marketing Ops • UK Focus
A practical, UK-focused guide to consent, email marketing, cookies, automation, and what changed post-Brexit.
Direct answer: UK marketers should treat GDPR as an always-on part of marketing ops: collect only the data you need, be transparent at every touchpoint, and send marketing emails only with a lawful basis (usually clear opt-in consent). Post-Brexit UK GDPR is broadly aligned with EU GDPR, but 2025 changes raise PECR penalties and tweak cookie rules—so get your martech configured properly.
GDPR isn’t “done”. Enforcement has kept climbing, and UK regulators now have sharper teeth for marketing and cookie breaches. Up to March 2025, the CMS GDPR Enforcement Tracker recorded 2,245 fines with total penalties of around €5.65 billion.[1]
The good news: privacy-led marketing tends to be better marketing. Recent survey data suggests 73% of shoppers prefer brands that handle email data transparently.[2] Trust isn’t fluffy — it’s conversion fuel.
In this guide you’ll get a clear UK view (UK GDPR + PECR), what changed in 2025, and a practical checklist you can hand to your marketing team (and your HubSpot admin) today.
Quick note: This is practical guidance for marketers, not legal advice. If you’re unsure about lawful basis, profiling, or international transfers, speak with your privacy lead or legal counsel.

Standalone answer: UK GDPR is the UK’s version of GDPR, retained after Brexit. It governs how you collect, store, use and share personal data — and marketing teams touch personal data constantly: email addresses, CRM activity, website tracking identifiers, form submissions, event registrations, and more.
In practice, UK GDPR is still broadly aligned with EU GDPR. The biggest difference is administration and oversight: the UK Information Commissioner’s Office (ICO) is the primary regulator in the UK, while EU enforcement runs through EU data protection authorities. In 2025 the UK introduced targeted reforms and raised penalties for certain marketing-adjacent breaches (more on that below).[3]
A simple rule: if you market to UK individuals (including B2B contacts, because people are still people), you must follow UK GDPR. If you also market to EU residents or process their personal data, EU GDPR can apply too — and you may need to consider cross-border requirements and representation.
The marketer’s version of GDPR: be clear, be fair, don’t hoard data, don’t surprise people, and make it easy to say “no”.
Every time you process personal data, you need a lawful basis. For most marketing email, the safest option is consent. In some B2B scenarios you might consider legitimate interests, but you still need to apply additional UK rules (PECR) for electronic marketing — and you must respect opt-outs, preferences, and transparency either way.
Think of valid consent as a clean “yes”: it must be clear, specific, informed, and given by an affirmative action (not pre-ticked, not buried). If your form copy makes people squint, it probably won’t satisfy a regulator.
If you run HubSpot, you can enable data privacy settings and restrict marketing sends to contacts who have a legal basis (opt-in).[4] That’s the difference between “we think we’re compliant” and “our platform enforces compliance by default”.
GDPR expects you to be transparent about why you’re collecting data, what you’ll use it for, who you’ll share it with, and how long you’ll keep it. The easiest way to operationalise this is:
Industry experts increasingly frame privacy as a trust and ethics issue, not just compliance — a shift that matters to marketing performance as much as risk management.[5]
People can request access to their data, correction, deletion, or object to processing (including direct marketing). The operational point: your marketing team should not be improvising when these requests land. The ICO’s guidance explains how to calculate the one-month response period (with worked examples).[6]
Data minimisation is a marketer superpower: fewer unnecessary fields, fewer messy spreadsheets, fewer risky exports. Keep only what you need, limit access, and make sure vendors (email, CRM, analytics, ad platforms) are properly configured. “It’s only marketing data” isn’t a defence — marketing databases are often the easiest doorway to reputational damage.
Whitehat perspective: GDPR works best when it’s baked into your inbound engine. That’s why we’re big on inbound marketing services (permission-based growth) and on configuring HubSpot so consent and preferences are enforced automatically — not managed in a fragile spreadsheet.
Standalone answer: UK GDPR remains closely aligned with EU GDPR, but 2025 reforms sharpened enforcement and updated rules around cookies and electronic marketing. For marketers, the headline is simple: the cost of sloppy consent and cookie practices has gone up.
The ICO confirms it has a range of enforcement tools for breaches of PECR (the UK rules covering electronic marketing and cookies), including fines up to £17.5 million or 4% of annual worldwide turnover for serious infringements.[7] Translation: cookie banners and “consent” are not UI fluff — they’re now a board-level risk.
A July 2025 legal analysis comparing UK and EU changes describes these reforms as the first substantial updates to GDPR since 2018, with the UK introducing amendments as part of its post-Brexit framework while remaining broadly aligned.[3]
2025 changes introduced more flexibility for certain low-risk cookies in the UK, but marketing/advertising cookies typically still require consent. The safest route is to keep a clear consent mechanism, distinct cookie categories, and documented third-party tracking — and to configure your platform accordingly (for example, HubSpot’s data privacy settings and consent tools).[4]
Practical takeaway: If your compliance depends on “everyone remembering to do the right thing”, it will fail. Make your tools enforce the rules (consent, subscription status, cookie categories) so your team can focus on strategy — not firefighting.
Standalone answer: GDPR compliance becomes manageable when you treat it as a repeatable marketing process: audit what you collect, fix consent at the source, configure your platforms to enforce legal basis, and document how you respond to rights requests.

One reason GDPR-friendly marketing works: it filters out low-intent contacts. Your list may be smaller, but it’s usually healthier — fewer complaints, better engagement, clearer segmentation, and more accurate reporting. And the trust angle is real: PrivacyEngine’s 2024 data suggests 73% of shoppers prefer brands that manage email data transparently.[2]
Usercentrics’ 2025 commentary frames this as a broader shift: consumers aren’t rejecting innovation or personalisation; they’re rejecting opacity. The winning brands are the ones that give people real clarity and control.[8]
Yes. The UK adopted GDPR into domestic law as the UK GDPR, and it still applies to UK marketers. If you handle personal data about UK individuals, UK GDPR applies; if you market to EU residents or process their data, EU GDPR may also apply. 2025 reforms strengthened enforcement around marketing and cookies, so the practical need for compliance is as strong as ever.[3]
Yes. GDPR applies to organisations of any size when they process personal data — including marketing data like email addresses, CRM records, and tracking identifiers. While your documentation can be proportionate, the essentials (lawful basis, transparency, security, and honouring rights) still apply.
Use clear, specific opt-in language at the point of data capture, with an affirmative action (for example, an unticked checkbox). Keep a record of when and how consent was given, make withdrawal easy (unsubscribe/preference options), and avoid bundling consent into other terms. Double opt-in can strengthen proof and list quality for email marketing.
Penalties depend on the breach, but the ICO can issue enforcement notices and significant fines. For serious infringements, the ICO notes fines can be up to £17.5 million or 4% of annual worldwide turnover and it also has enforcement powers for PECR breaches related to direct marketing and cookies.[7]
Yes — if your tools are configured to respect consent, subscription preferences, and lawful basis. Many platforms support consent capture and can restrict marketing emails to contacts with a legal basis. HubSpot, for example, documents how to turn on data privacy settings and enforce “send only with legal basis”.[4] For analytics/advertising cookies, use a compliant consent banner and keep your vendor list documented.
GDPR compliance doesn’t have to be the thing that slows marketing down. In 2025, the teams winning are the ones who build privacy into the system: cleaner consent, clearer messaging, better segmentation, fewer risks, and stronger trust.
