ASA Compliance for Training Providers: Avoiding Misleading Marketing Claims

A line that feels like harmless promotional flourish, "the UK's leading provider," "government-approved standards," "trusted by thousands," can be enough to land a training business in front of the Advertising Standards Authority. It has already happened, more than once, within the CPD accreditation sector itself, and the rulings that followed set out exactly what the ASA expects, in enough detail that any training provider can use them as a practical checklist for their own marketing.

The "Leading Body" Ruling

On 6 May 2026, the ASA upheld a complaint against The Professional Development Consortium Ltd, trading as CPD Standards Office, over two paid-for Meta ads stating "CPD accreditation from the UK's leading body." The complaint, brought by The CPD Register Ltd, challenged whether that claim was misleading and could be substantiated, and whether it was verifiable.

CPD Standards Office said the wording was general promotional positioning rather than a precise "number one" claim, and pointed to its operating history, the number of organisations it had accredited, its cross-sector reach and its testimonials. The ASA upheld both issues. It considered that consumers were likely to understand the claim to mean CPD Standards Office was the CPD accreditation body with the largest market share in the UK, and that evidence relating only to its own market position was unlikely to prove that.

Robust comparative evidence, covering a reasonable period of time and showing higher UK turnover or a greater UK market share than competitors, or an equivalent objective measure, would have been needed. The ASA also considered that the claim was a comparison with identifiable competitors, even though none were named, and the ads gave consumers no way to check it. The ads breached CAP Code rules 3.1 (misleading advertising), 3.7 (substantiation) and 3.35 (comparisons with identifiable competitors).

This isn't an isolated interpretation. The ASA's own published guidance on "No. 1" claims and "best-selling" claims applies the same standard across every sector. A holiday rental company's "#1 holiday website on the planet" was ruled misleading because it provided no evidence of the largest turnover of holiday rentals compared with its global competitors. A lettings agent's "Derby's No.1 Award Winning Agent" was ruled potentially misleading, and the fact that it had more company vehicles, staff and branches than its rivals wasn't enough to support the claim. By contrast, Ryanair's "Europe's number one airline" was not considered misleading, because Ryanair could show it had carried more passengers than any other European airline. The principle is consistent: the claim and the evidence have to match.

Worth clarifying here, since both organisations are named in this piece: The CPD Register is a separate, independent organisation from The CPD Group. We're certified by The CPD Register, and we submit the activities we accredit to their register on behalf of our providers, but the two are not the same company, and the complaint above was made by The CPD Register in its own right, not by us.

The "Government-Approved" Ruling

An earlier case makes a different point just as clearly. On 28 August 2024, the ASA upheld a complaint against The CPD Regulatory Office, raised by The CPD Group Ltd, over website claims that it was "working alongside government bodies" and that its approved providers met "government-approved standards." The site also displayed the logos of 19 other organisations under the heading "APPROVED CPD & ACCREDITATION SERVICE PROVIDERS."

All three issues investigated were upheld. The ASA said it had not been provided with any evidence that The CPD Regulatory Office worked with government bodies, that the CPD training industry was regulated through standards set by government, or that The CPD Regulatory Office provided government-approved authorisation to CPD training companies. It also ruled that the logos would be read as meaning those organisations had been assessed and approved by The CPD Regulatory Office, and that, without evidence of that relationship, their use was likely to mislead.

The CPD Regulatory Office did not respond to the ASA's enquiries, which the ASA ruled was a breach of CAP Code rule 1.7 (unreasonable delay) in its own right. The ASA's non-compliant online advertisers listing also shows that, despite repeated requests from the CAP Compliance team, the claims stayed on the website. On 5 February 2026, the ASA reissued the listing, which remains in place until the claims are removed.

How This One Was Spotted

The ASA's ruling records that The CPD Group Ltd raised the challenge because it understood CPD to be an unregulated industry, not overseen by the UK government, with no government-approved standards. Claims of working alongside government bodies and meeting government-approved standards didn't fit with that, so we challenged them. That gap matters because training providers rely on accurate information to make a genuinely informed choice about who accredits their work, and a misleading claim of government approval gets in the way of that. Noticing it, and being willing to challenge it, is part of what keeping the wider market honest looks like in practice, and it's the same standard we hold ourselves to.

The Wider Principles, With Real Precedent

Both rulings above concern accreditation bodies rather than training providers marketing courses directly, but the same CAP Code rules apply to how you describe your own business. A few areas worth checking against your own copy, each backed by the ASA's own published rulings and guidance:

Hold your evidence before the ad goes live. CAP Code rule 3.7 says that before a marketing communication is published, marketers must hold documentary evidence to prove any claims that consumers are likely to regard as objective. Evidence gathered after someone complains doesn't meet that rule.

Testimonials alone don't substantiate a factual claim. The ASA's guidance is clear that genuine testimonials can appear in ads, but they don't by themselves prove an objective claim. Customer survey comments about saving money on energy bills weren't accepted as evidence for savings claims, and in 2023, emails from two clients weren't accepted as evidence for claims about the efficacy of treatments. If your marketing says "our course improves X" and your only backing is a handful of glowing reviews, that claim is more exposed than it might feel.

"Leading" and "number one" are objective, evidence-needing claims, even when you don't name a competitor. Under rule 3.2, obvious exaggeration (puffery) that people are unlikely to take literally is allowed, provided it doesn't materially mislead. But the ASA's guidance says "number one" claims will almost always be treated as objective comparisons, and an unqualified claim is likely to be read as a comparison with the entire market. If you qualify a claim, your evidence needs to match that qualification.

Comparisons don't need to name anyone to count as comparisons. As the CPD Standards Office ruling shows, if your audience could identify the competitors you're being compared with, the ASA treats the claim as a comparison with identifiable competitors, and that means it has to be verifiable.

Logos and endorsements imply a real relationship. Displaying another organisation's name or logo, whether a past client, a partner or an accreditor, implies that relationship exists and is accurately represented. If it has lapsed, or was never quite what the logo suggests, it's a live risk.

Always respond to the ASA. The CPD Regulatory Office case shows that not responding doesn't make a complaint go away. The ASA treated the silence as a breach of the Code in its own right.

Building Compliance Into How You Market

None of this requires abandoning confident marketing. It requires making sure confident claims are also accurate, specific and provable before they go live, not after someone asks. At The CPD Group, we hold our own marketing to that same standard: our A.C.C.R.E.D.I.T.E.D Framework criteria are published in full rather than described vaguely, and when we accredit an event, we describe ourselves as its "CPD accreditation partner" rather than using broader claims that could be read as an endorsement.

If you're reviewing your own marketing with ASA compliance in mind, the rulings above are a useful starting point for what to check first. The CPD Group can also help you get your courses, webinars, events or podcasts properly and verifiably accredited, giving you something concrete and evidenced to point to, rather than a claim that might not hold up if the ASA ever asks.
