Post-Brexit PR agency guide to UK-EU campaigns

What to take away

The EU-UK regulatory split after Brexit and what it means for PR

The EU-UK regulatory split is the gap between two rulebooks that used to be one. For a PR agency, that gap shows up in advertising codes, financial promotions, data and broadcasting.

The UK left the EU on 31 January 2020 and the transition period ended on 31 December 2020. Since then, EU regulations no longer apply directly in Great Britain. They still apply in Northern Ireland for many goods and market rules under the Windsor Framework.

Retained EU law, now called assimilated law, keeps much of the old text in UK statute. The core data text is Regulation (EU) 2016/679, read with the Data Protection Act 2018.

A UK campaign can therefore cite the same principles as an EU one but must apply the UK version.

Advertising rules differ by market. In the UK, the Advertising Standards Authority (ASA) administers the CAP Code for non-broadcast advertising; broadcast advertising is covered by the BCAP Code under ASA and Ofcom arrangements. In Ireland, the Advertising Standards Authority for Ireland (ASAI) applies its own code. A claim cleared in London is not automatically cleared in Dublin.

At EU level, the Audiovisual Media Services Directive (AVMSD) sets rules for audiovisual commercial communications, while the Unfair Commercial Practices Directive (UCPD) addresses unfair commercial practices. Both are applied through national laws. The European Advertising Standards Alliance (EASA) coordinates advertising self-regulation but is not an EU regulator. In France, ARCOM regulates audiovisual communication and ARPP is the advertising self-regulatory body; Germany's Deutscher Werberat is also a self-regulatory body.

Financial promotions are stricter still. The Financial Conduct Authority regulates promotions in the UK, including relevant social posts, podcasts and influencer content. For EU-facing investment campaigns, MiFID II (Directive 2014/65/EU) requires investment-firm marketing communications to be fair, clear and not misleading where it applies; national competent authorities supervise firms, and the European Securities and Markets Authority (ESMA) issues EU-level guidance.

The Windsor Framework and its effect on Northern Ireland messaging

The Windsor Framework replaced the Northern Ireland Protocol in 2023. It creates a dual regime: Northern Ireland follows EU rules for goods and some market rules, and UK rules for most services.

For PR work, the practical effect is that Northern Ireland messaging can be true in Belfast and misleading in Dublin, or the reverse. A product claim about standards, origin or availability may need two versions.

Green lanes and red lanes govern goods moving from Great Britain to Northern Ireland. A campaign that promotes a product as available across the UK may need to qualify that for Northern Ireland if the product moves on the red lane.

The framework also gives the Northern Ireland Assembly a say through the Stormont Brake on amended EU rules. That creates a political news cycle an agency should track before it plans a launch.

Language matters. Terms such as UK-wide, all-Ireland and cross-border carry different legal and political weight in Northern Ireland. Test copy with local reviewers, not only with a London legal team.

Media in Northern Ireland spans Belfast-based outlets, Dublin-based outlets with northern editions, and community and Irish-language titles. A single press release will not fit all three.

Do not assume one UK sign-off settles every issue. Identify the regulator and rules for the channel, claim and relevant nation before drafting.

PR agencies to shortlist for cross-border campaigns

A starting shortlist of international PR agencies and communications firms includes:

These are directory starting points, not endorsements. Confirm directly which country teams can support your markets, media relationships and regulatory reviews.

Planning media flows across the Irish border

Irish border media is not one list. It is a set of outlets that report on both jurisdictions but publish under different laws. Plan the list before the story.

Start with jurisdiction. A story placed in a Dublin title reaches readers in the Republic of Ireland and Northern Ireland, but the publisher is bound by Irish law. A Belfast title reaches the same island under UK law.

For EU audiences beyond Ireland, name outlets in each target country rather than treating the EU as one media market. Examples include Le Monde in France and Frankfurter Allgemeine Zeitung in Germany. Confirm the language, edition, readership and pitch route for each.

Defamation rules differ. Northern Ireland defamation law was reformed by the Defamation Act (Northern Ireland) 2022, while the Republic of Ireland operates its own Defamation Act 2009. A claim safe in one may be actionable in the other.

Broadcasting adds another layer. Ofcom regulates UK broadcasters under the Broadcasting Code. Irish broadcasters fall under Coimisiún na Meán. A broadcast interview can be regulated in one market and not the other.

Embargoes and time zones are simple, but not identical. Both jurisdictions use Greenwich Mean Time in winter and Irish Standard Time in summer, so no clock change is needed. Still, news desks in Dublin and Belfast keep different diaries.

Use this sequence to build the media plan:

For teams that treat media lists and stakeholder data as a data flow before any label is applied, the mapping discipline is the same: name the source, the lawful basis and the destination.

Data flows and international transfers for cross-border PR

International data transfers are the part of cross-border PR most likely to fail an audit. Moving a media list, a journalist contact or a supporter database across the border is a transfer.

The UK operates its own data regime. The retained EU GDPR text applied in the UK, read with the Data Protection Act 2018, sets the statutory framework for UK GDPR and the journalism exemptions.

The ICO publishes ICO international transfers guidance, including the transfer risk assessment and the International Data Transfer Agreement. Use it before sending EU contact data to a UK CRM or a US newsroom tool.

Where EU GDPR applies to a UK organisation with no EU establishment, Article 27 can require it to appoint an EU representative, subject to the regulation's exceptions. For electronic marketing and cookies, also check the ePrivacy Directive (Directive 2002/58/EC) as implemented in each member state; national rules and regulators differ.

The EU side is separate. The European Commission adopted an adequacy decision for the UK on 28 June 2021, allowing personal data to flow from the EU to the UK without extra safeguards. The Commission reviews the decision periodically, so verify its current status before relying on it.

Special category data raises the bar. Health, political opinion and trade union data need an Article 9 condition and, for transfers, a higher level of assurance. Press offices rarely need this data, so collect less.

ONS international trade data helps set the economic context for a campaign, but it does not decide a transfer question. Use it for the story, not for compliance.

A cross-border campaign planning template

A cross-border campaign template keeps the legal, media and data work in one place. Use it as a live document, not a one-off form.

Section 1: Scope. Name the markets, the audiences and the languages. State whether Northern Ireland is in scope and under which regime.

Section 2: Claims register. List every factual claim, the evidence, the approver and the markets where it may run. Mark claims that cannot run in one jurisdiction.

Section 3: Media map. List outlets by jurisdiction, with the regulator and the defamation regime for each. Add the named contact and the embargo rule.

Section 4: Data map. List every personal data set, the lawful basis, the storage location and any transfer mechanism.

Section 5: Approvals. Name the legal reviewer in each jurisdiction and the sign-off deadline. No copy ships without both signatures where two markets are in scope.

Section 6: Issues plan. List the three most likely criticisms in each market and the holding line. Include the Stormont Brake and any live EU rule change in Northern Ireland.

Section 7: Measurement. Agree the metrics before launch: share of voice by jurisdiction, message pull-through, and coverage quality. Avoid comparing raw counts across markets with different media density.

A UK fintech launches a savings product in Great Britain, Northern Ireland and the Republic of Ireland. The claims register flags a rate claim that needs FCA-approved wording in the UK and a separate Irish wording.

The media map splits Belfast and Dublin desks. The data map records the CRM in London and the transfer mechanism for EU sign-ups. The issues plan prepares a response to a rate-change story. Launch holds until both legal reviewers sign.

Common pitfalls in cross-border PR after Brexit

Assuming one press release covers both markets. It rarely does. Legal terms, product availability and political context differ, and local desks notice.

Treating Northern Ireland as a subset of Great Britain. The Windsor Framework makes it a dual regime. Copy that ignores this can be wrong on the day it runs.

Leaving data transfers to the last week. Transfer risk assessments and agreements take time. Start before the media list is built, not after.

Using one defamation read for the whole island. Two legal systems apply. A single review by a London lawyer is not enough for a Dublin publication.

Ignoring devolved regulation. Health, education and some environmental messaging differ across Scotland, Wales and Northern Ireland. Devolution changes PR strategy in ways a single London sign-off will miss.

Measuring coverage without jurisdiction tags. A coverage report that mixes UK and Irish outlets hides whether the campaign reached the audience it was planned for.
