Podcast advertising regulations UK: CAP Code disclosure, claims and listener data
UK podcast ads fall under the CAP Code, not the BCAP Code. This guide explains disclosure, evidence for claims, restricted categories and listener data basics.
What to take away
- Podcast ads in the UK count as non-broadcast advertising, so the CAP Code applies and the ASA enforces it.
- Sponsor credits, host reads and affiliate plugs must be obviously identifiable as advertising.
- Claims, prices and testimonials need evidence you can produce on request.
- Listener data used for targeting or measurement brings UK GDPR and PECR into play.
Podcasts sit under the CAP Code, not the BCAP Code
Broadcast radio in the UK is governed by the BCAP Code, which sits on the Communications Act 2003 and is enforced by the Advertising Standards Authority. Podcasts are a different case. An ad inside a streamed or downloaded episode is non-broadcast advertising, so the CAP Code applies instead.

Commercial radio ads are usually cleared in advance by the Radio Advertising Clearance Centre. Podcast ads are not. You self-certify, and the ASA can rule against you later if a listener complains.
Both codes are published together by CAP and the ASA on the same advertising codes page, which is why advertisers often confuse them. Check the code that matches the medium before you book inventory. If you are still choosing between the two, our guide on digital audio advertising vs radio sets out the trade-offs.
Disclosure rules for sponsorship and host reads
Rule 2.1 of the CAP Code requires ads to be obviously identifiable. A sponsor credit is an ad when money, goods or a discount changes hands, so it cannot pass as editorial. A host read that praises a product needs a spoken label, usually at the start.
Disclosure checklist for host reads
- Label ads obviously identifiable
- Disclose sponsor credit when money changes hands
- Say paid partnership at the start
- Disclose affiliate commission before recommendation
- Avoid coy thank-you to our partners
Affiliate links and discount codes count too. If the host earns commission, say so before the recommendation, not after it. The ASA treats missing disclosure as a misleading ad rather than a formatting slip.
Keep the wording plain. A spoken line such as paid partnership with the brand does the job. A coy thank-you to our partners gives listeners no way to weigh the recommendation.
Claims, prices and evidence
The rules on claims do not change because the medium is audio. Before you record, hold evidence for anything factual, including savings figures, awards and comparisons.
Prices must be accurate for the whole time the ad runs. A time-limited offer needs a clear end date, and a from price needs the qualifying detail.
Testimonials must be genuine, and the results described should reflect what a typical customer gets rather than the best case. Keep dated records for each claim with the source attached, because the ASA can ask for them when it assesses a complaint.
Children, restricted categories and listener data
Where a podcast has a large child audience, the CAP Code asks for extra care. Ads must not exploit inexperience or pressure a child to buy.
Alcohol, gambling, e-cigarettes and less healthy food and drink all face limits that vary by medium and audience. Check the sector rules before you write.
Targeting listeners with data, or measuring who responded, means processing personal data. The ICO's UK GDPR guidance covers the lawful basis, consent and transparency duties that follow. For measurement that stays inside those rules, see how to track podcast ad response and attribution.
A short compliance checklist
- Confirm which code applies, CAP for podcasts and BCAP for broadcast radio.
- Write the disclosure line first and place it at the start of the read.
- List every claim, price and comparison, with a source attached to each.
- Check restricted-category and children's rules for your sector.
- Map where listener data is collected, why, and on what lawful basis.
- File the script, booking and evidence together.
This is general guidance rather than legal advice, and a specific campaign may need a qualified adviser.
Common questions
Do podcast ads need pre-clearance in the UK?
No. Podcast advertising sits outside the radio clearance system, so nothing approves the script before it runs. Financial promotions are the exception, because an authorised firm must sign off the content.
Who enforces the CAP Code?
The ASA. It investigates complaints, publishes rulings and can require a campaign to change or stop. Repeat breaches can be referred to other regulators.
Does a sponsor credit count as advertising?
Yes, whenever value changes hands. The commercial intent has to be clear to the listener, so a plain label beats a coded thank-you.
Can listener data be used to target podcast ads?
Yes, within UK GDPR and PECR. You need a lawful basis and, for many identifiers used in marketing, consent, plus a privacy notice that says what happens to the data.
