Rules and ethics
Do Cardiff and Belfast podcast buys face different rules?
Podcast sponsorship in Cardiff and Belfast differs: Welsh-language commissioning, cross-border advertising, Ofcom, ICO and CAP Code duties vary.
What to take away
- On-demand podcasts are not licensed broadcast services, so Ofcom's Broadcasting Code generally does not apply in either city. The CAP Code does.
- Cardiff buys can carry Welsh-language funding conditions from S4C or the Welsh Government, plus Welsh Language Commissioner standards for public bodies.
- Belfast buys that reach listeners in the Republic of Ireland may face Advertising Standards Authority for Ireland rules.
- UK VAT normally covers UK digital advertising, but an all-island Belfast invoice can raise Irish VAT questions.
One statute book, two local layers
Yes, but the divergence is local rather than statutory. Both cities share one legal baseline. The Communications Act 2003 gives Ofcom powers over licensed broadcasting across the UK, and podcast sponsorship is not licensed broadcasting.
The differences come from funding and geography. Cardiff adds a Welsh-language layer. Belfast adds a border. Neither adds a separate UK statute.
Both markets share the CAP Code, written by the Committee of Advertising Practice and enforced by the ASA. It covers sponsorship credits and host-read ads, including recognisability and misleading claims, as the ASA's advertising codes explain.
For the baseline duties that apply in both cities, see our guide to podcast advertising UK regulations.

Cardiff: funding conditions and Welsh-language rules
Cardiff's extra layer is commissioning. S4C commissions Welsh-language content and publishes its own sponsorship guidelines. The Welsh Government funds Welsh-language broadcasting. The Welsh Language Commissioner sets language standards for public bodies.
Where a show has public production funding, expect conditions on credits, category exclusivity and language balance. Ask the producer which body funded the series. A credit that ignores those terms can be rejected.
Welsh-language shows often have smaller but more engaged audiences, which can justify a premium where the producer can evidence completion rates.
Belfast: cross-border reach, ASA Ireland and the BAI
A Belfast podcast may be downloaded in Dublin, so Irish rules can apply to the ad content. The Advertising Standards Authority for Ireland administers the Irish marketing communications code. The Broadcasting Authority of Ireland regulated licensed Irish broadcasters until its functions passed to Coimisiún na Meán in 2023, so those codes reach broadcast output rather than ordinary podcasts.
Decide whether the buy is UK, Irish or all-island, because that choice sets the contract, the invoice and the evidence. Our article on cross-border campaigns and UK GDPR differences with Ireland covers the data safeguards an all-island buy may need.
If you promise all-island reach, your measurement source must cover both jurisdictions. RAJAR reports UK listening quarterly, and Irish audio measurement uses different panels. Ask for the survey quarter and the dashboard export date behind any figure.
Pricing and booking: what changes
Pricing reflects audience size, language and reach, not a fixed city tariff. Ask for a rate card, the audience source and its date.

- Audience size
- Smaller, often bilingual
- Language premium
- Possible for Welsh shows

- Funding body
- Northern Ireland Screen, where applicable
Northern Ireland Screen funds film, television and digital content production in Northern Ireland. It is not an advertising regulator, so it matters only where a producer has received its funding and conditions attach.
Booking steps:
Pricing and booking
- Confirm the territory the schedule covers before agreeing a rate.
- Ask which funding body or cross-border rule attaches to the show.
- Request audience figures with a dated source and survey period.
- Sign a schedule naming the regulator and the VAT treatment.
Example, illustrative arithmetic only and not a market rate: £2,000 across 40,000 downloads is £50 per thousand. The same £2,000 across 10,000 engaged Welsh-language downloads is £200 per thousand.
VAT follows the customer's location for digital services, so check which entity invoices you. Our guide to VAT and invoicing for UK podcast sponsorship explains invoice wording for cross-border schedules.
The evidence file to keep for each market
Keep one file per market, because finance, legal and regulator questions arrive separately.
- Audience figures with the source, survey quarter and export date.
- Consent records and a documented lawful basis for tracking or newsletter sign-ups.
- A signed schedule naming the territory, regulator and VAT treatment.
- Evidence for Welsh Language Commissioner standards or Irish advertising rules, as the market requires.
Data protection duties come from UK GDPR and the ICO's UK GDPR guidance and resources.
Common questions
Does Ofcom regulate podcast sponsorship?
No, not for ordinary on-demand shows. The Broadcasting Code covers licensed broadcast radio and television. If a licensed broadcaster publishes the podcast as part of its output, Ofcom's rules can still apply.
Which Irish bodies matter for a Belfast buy?
The Advertising Standards Authority for Ireland covers marketing communications aimed at Irish audiences. Coimisiún na Meán, which took over the Broadcasting Authority of Ireland's functions, regulates licensed Irish broadcasters rather than ordinary podcasts.
Can one contract cover both cities?
You can, but separate schedules are safer. Territory, regulator and VAT treatment differ, and one set of terms can leave gaps on Welsh-language approval or Irish consent.
