Choosing an influencer marketing agency in Northern Ireland: the cross-border rules to check

What to take away

Questions to put to a shortlisted agency

When you compare influencer marketing agencies in Northern Ireland, the rules below turn into questions you can ask each one. An agency that has run all-island work should answer them without hesitation. Pair them with the checks in auditing an influencer agency.

How the CAP Code applies in Northern Ireland

The CAP Code applies across the United Kingdom, and Northern Ireland is not an exception. The Non-broadcast Code sets the rules for ads in non-broadcast media, which covers influencer posts, stories, reels and paid creator content. The ASA enforces it.

That means a Belfast agency placing a gifted stay for a creator is doing CAP Code work, not just PR. Recognition matters. If a creator has a commercial relationship with a brand, the content must be obviously identifiable as an ad. The CAP Code also covers misleading claims, comparisons, promotions and the use of testimonials.

Northern Ireland adds a practical wrinkle. Some campaigns are bought by Dublin teams and run on all-island media plans. The CAP Code applies to the UK-facing non-broadcast advertising, while the Republic of Ireland advertising checks should be made against the ASAI Code of Standards for Advertising and Marketing Communications. One brief can therefore require checks under two advertising codes.

A useful starting point is to treat every creator post as an ad unless there is a clear reason it is not. The CAP Code's scope is broad, and the ASA has repeatedly said that editorial-looking content can fall inside it. If a brand paid, gifted or otherwise controlled the creator, assume the code applies.

An agency's responsibilities depend on its role, but a campaign can engage the advertising, consumer law, privacy duties as well as the brand's. UK consumer protection requirements include Part 4 of the Digital Markets, Competition and Consumers Act 2024; in the Republic of Ireland, the Consumer Protection Act 2007 and the Competition and Consumer Protection Commission (CCPC) are relevant. For personal data within the UK regime, see the data protection guide and check the UK GDPR and Data Protection Act 2018, with the Information Commissioner's Office (ICO) as the UK data protection authority. Where EU GDPR applies to the campaign's processing, the Irish Data Protection Commission is the supervisory authority.

What the CAP Code covers in creator ads

This table is not a substitute for reading the code. It is a planning aid for a Northern Irish agency writing a brief. The CAP Code covers non-broadcast advertising, including most creator posts on social media; the BCAP Code covers broadcast advertising. The ASA publishes both codes in full.

How the ASA regulates in practice

The ASA is a self-regulatory body, and its system works alongside law. The About regulation page explains how the ASA, CAP and BCAP fit together. For a Northern Irish agency, the practical effect is that a complaint can lead to a ruling, an ad alert and a demand to change or withdraw the ad.

The ASA cannot fine a creator directly. It can refer persistent offenders to trading standards, which can act. In Northern Ireland, the Trading Standards Service (TSS), part of the Department for the Economy, is the consumer enforcement body to identify for relevant referrals. That is why the reputational cost of a ruling is often the real sanction. A Belfast brand named in a ruling will feel it in retail and wholesale relationships.

Ofcom online safety duties and cross-border ads

Ofcom is the communications regulator for the UK. The Communications Act 2003 underpins its communications remit, while the Online Safety Act 2023 gives it online safety functions for regulated user-to-user services and search services. Its role reaches platforms, not just broadcasters, which matters for creator ads.

Under the Online Safety Act 2023, Ofcom oversees regulated services' duties and publishes the Illegal Content Codes of Practice, the Children's Safety Codes of Practice and related online safety guidance. These duties fall on in-scope services, not creators or agencies simply because they publish an ad there. The platform's duties concern its systems for illegal content and, where applicable, children's access to harmful content.

The agency is not the platform. But the agency's campaign can create risk for the platform and the brand. If a campaign encourages harmful behaviour, or targets children with unsuitable content, the platform's systems may act. The brand may then find the campaign pulled.

Where Ofcom bites for a Northern Irish campaign

Ofcom's online safety work is not a general advertising code. It does not replace the CAP Code. It sits on top of it for content on regulated services. The overlap is the point.

A creator ad that is also user-generated content on a regulated platform can be looked at through both lenses. The ASA asks whether the ad is identifiable and not misleading. Ofcom's framework asks whether the platform has done its online safety duties. Those are different questions with different consequences.

For an all-island campaign, Ofcom's online safety role concerns services within the scope of UK law; it is not a second advertising code. The Republic of Ireland has its own media regulator, Coimisiún na Meán, and its online safety framework under the Online Safety and Media Regulation Act 2022. A Northern Irish agency running one campaign across both jurisdictions should check the platform's regulatory position as well as the advertising rules for each market.

What this means for briefs

A brief that says "make it go viral" is a risk. A brief that says "keep it suitable for the audience and label it clearly" is safer. Northern Irish agencies should add an online safety line to every creator brief: no harmful content, no age-inappropriate targeting, and a route for the creator to flag a problem.

The regulations, codes and platform rules that apply to UK creator work are layered, but not interchangeable. The CAP Code governs non-broadcast ad content; platform terms govern use of the service, while Ofcom's Online Safety Act duties fall on in-scope services rather than the agency or creator. Briefs should keep these checks distinct.

Campaigns that also run in the Republic of Ireland

An all-island campaign is common in Northern Ireland, and it is where cross-border advertising gets complicated. The Republic of Ireland has its own advertising code, enforced by the Advertising Standards Authority for Ireland (ASAI). The ASA in the UK does not enforce the Irish code.

That means a single creator post can need two disclosures. A UK audience needs a CAP Code compliant label. An Irish audience needs a label that meets the Irish code. In practice, the safest approach is one label that satisfies both.

The practical split

Use this five-step routine for a cross-border creator ad:

What changes for Republic of Ireland campaigns

Currency, pricing and availability claims often differ. A price in euro and a price in sterling must both be accurate for the audience that sees them. If a campaign offers a promotion, the terms must be clear in both markets.

Consumer law differs too. UK consumer protection requirements include Part 4 of the Digital Markets, Competition and Consumers Act 2024. In the Republic of Ireland, the Consumer Protection Act 2007 and the CCPC are relevant to consumer protection and enforcement. A Northern Irish agency cannot assume that a UK-compliant claim is automatically fine south of the border.

Language and idiom matter less than law, but they still matter. A script written for Belfast may read oddly in Cork. That is a creative issue, not a compliance one, but it affects how the disclosure lands.

Disclosure differences a UK agency must plan for

Disclosure is where cross-border campaigns fail most often. CAP Code rule 2.1 requires marketing communications to be obviously identifiable as such; rule 2.3 says they must not falsely claim or imply that the marketer is acting as a consumer or outside its trade or business. For Republic of Ireland advertising, the ASAI Code of Standards for Advertising and Marketing Communications requires marketing communications to be clearly recognisable as such; if the commercial nature is not clear from context, identify it plainly as advertising. The ASA's "Influencers' guide to making clear that ads are ads" and the ASAI's influencer marketing guidance are practical references for applying those requirements.

For a UK audience, put a clear label such as "Ad" at the start of the caption and make it visible wherever the content appears. For an Irish audience, the ASAI Code's recognisability requirement also applies; use a prominent, plain-language label such as "Ad" or "Paid partnership" rather than relying on an ambiguous hashtag or the platform tool alone.

Use a clear, plain label in the first line of the caption and a platform tool as backup: Meta's "Paid partnership" label on Instagram and Facebook, TikTok's content disclosure setting, or YouTube's paid promotion declaration, as applicable.

A worked example

A Belfast skincare brand books a creator based in Newry. The creator's audience is 60 per cent Northern Ireland, 25 per cent Republic of Ireland and 15 per cent Great Britain. The campaign is a paid post plus a gifted product.

Step one: the agency treats the post as an ad under the CAP Code. Step two: it checks the ASAI Code of Standards for Advertising and Marketing Communications because a quarter of the audience is in the Republic of Ireland. Step three: it writes a caption that says "Paid partnership with [brand]" in the first line.

Step four: it switches on the platform's relevant branded content or paid promotion disclosure tool, such as Meta's "Paid partnership" label, TikTok's content disclosure setting or YouTube's paid promotion declaration. Step five: it saves a screenshot of the final post and a note explaining the choice.

That example is deliberately ordinary. Most cross-border decisions are ordinary. The risk comes from skipping the note.

The disclosure checklist

The influencer disclosure policy that a UK agency writes should cover both markets if it runs all-island work. A policy written only for England will leave gaps for Northern Ireland and the Republic of Ireland.

What to avoid

Do not rely on a hashtag alone. Do not hide the label after a wall of hashtags. Do not assume a platform tool is enough on its own. Do not use vague words such as "collab" or "sp" without a clear ad label. Do not let the creator choose the wording without a check.

Where ASA and Ofcom remits overlap

The ASA and Ofcom are different regulators with different powers. The ASA regulates advertising content under the CAP and BCAP codes. Ofcom regulates communications services, including broadcasting and online safety. The overlap is real but narrow.

A creator ad on a regulated platform can be both an ad and user-generated content. The ASA looks at the ad. Ofcom's framework looks at the platform's systems. The brand and the agency are mainly in the ASA's lane, but platform decisions can affect the campaign.

A simple way to see the split

This split is a planning tool. It tells a Northern Irish agency which regulator to think about at which stage. It does not remove the need to read the codes.

Where the confusion starts

Confusion usually starts when a campaign is described as "content" rather than "ad". If the brand paid or gifted, it is an ad. If it is an ad on a regulated platform, both the ASA and the platform's Ofcom-facing duties can be in play.

The recognition, claims and incentives checks that apply in England apply in Northern Ireland too. Recognition, claims, incentives and placement are the four things a compliance check should cover before a post goes live.

What the ASA can and cannot do

The ASA can investigate, rule and publish. It can require changes. It can refer persistent offenders to trading standards. It has no power to fine. Ofcom can fine regulated services, but not individual creators for ad labelling.

That asymmetry matters for risk planning. A brand's biggest exposure on a creator ad is usually reputational and commercial, not a direct fine. A platform's exposure under online safety duties can be financial.

Documenting the cross-border decision

Documentation is the least glamorous part of cross-border work and the most useful. A dated note that explains which code applied, which label was used and why can end a complaint quickly. It also helps when a client asks why the Irish version of a post looks different.

What a good record contains

Keep the record for as long as the campaign runs and for a reasonable period after. If a complaint arrives months later, the note is the difference between a calm reply and a scramble.

A short template

Use this one-page template to record the decision:

Campaign: [name]
Date: [date]
Creator and platform: [details]
Markets and audience split: [details]

Online safety service regulator, if relevant: [Ofcom, Coimisiún na Meán, or other applicable position and reason]
Final post and platform tool evidence: [record location]
Sign-off name and date: [details]

That template also helps an agency pitch. Clients running all-island campaigns want to know that the agency has thought about both jurisdictions. A documented process is a selling point, not just a shield.

Reviewing the decision

Codes change. Platform tools change. Audience splits change. A cross-border decision made in one quarter may not hold in the next. Put a review date on the record and revisit it if the campaign runs long.

If the campaign expands into Great Britain, the same CAP Code applies, but the audience mix changes. If it expands into the Republic of Ireland, the Irish code comes in. The record should show that the agency noticed.
