ASA and CMA rules for scheduled advertising claims on UK social media

What to take away

Who the ASA and CAP are and what the CAP Code covers on social

In the UK, the Advertising Standards Authority acts as the independent regulator for advertising. It administers the CAP Code for non-broadcast advertising and the BCAP Code for broadcast.

Both sit under the Committee of Advertising Practice, and they are published together on the ASA site, which sets out the advertising codes that govern claims in UK ads.

Social media is squarely non-broadcast advertising. A paid post, a boosted reel, a brand's own organic post making a claim, an influencer post the brand controls: all fall within the CAP Code's scope. The medium does not exempt the message.

That matters for scheduling because the CAP Code applies at the point of publication. A post queued on Tuesday for release on Friday is judged on Friday's wording, price and availability, not on the draft that was approved three weeks earlier.

Where the CAP Code stops and other law starts

The CAP Code covers advertising claims and their presentation. It does not cover data protection, which is the Information Commissioner's Office's territory under UK GDPR and the Data Protection Act 2018, nor electronic marketing consent, which sits under PECR.

A single scheduled post can touch all three regimes. A retargeting ad with a price claim and a consent-based audience is an ASA matter, an ICO matter and a PECR matter at once. Compliance teams should not treat them as alternatives.

The ASA also cannot fine. It refers persistent non-compliance to Trading Standards, which can act under consumer protection legislation. That division shapes how sanctions escalate, covered later.

Sector codes sit on top

The CAP Code has sector-specific supplements. Health claims, alcohol, gambling, financial promotions and weight control all carry extra restrictions that a general social calendar will not flag on its own.

If your brand operates in one of those sectors, the scheduling workflow needs a second reviewer with sector knowledge. A generic approval step is not enough.

Misleading claims rules applied to scheduled advertising copy

The core rules live in section 3 of the CAP Code, which sets out the misleading advertising provisions the ASA applies to claims. Most ASA rulings against social posts turn on this section rather than on anything exotic.

A claim is misleading if it deceives, or is likely to deceive, the people it reaches, and if it is likely to affect their decisions. Intent is irrelevant. A copywriter who believed the claim was true does not fix a misleading post.

The claims that break in scheduled social copy

Price claims are the most common failure. A scheduled post that says a discount ends Sunday, but runs again the following week, is misleading even if the first post was accurate when queued.

Availability claims fail the same way. "While stocks last" scheduled for a campaign that has already sold out is a misleading claim in a live post.

Comparative claims need like-for-like evidence. "Better than" or "the UK's fastest" requires a defined comparison set and a date. Without both, the claim is unsubstantiated.

Free offers need their conditions stated. If delivery costs apply, the word free needs qualifying in the same post, not in a linked page most of the audience never opens.

Qualifications have to travel with the claim

A qualification in a landing page does not cure a misleading headline claim in a social post. The ASA expects the qualification to be prominent enough that the audience sees it with the claim.

Character limits make this hard, which is why short-form claims should be narrowed until they are true without a footnote. If the claim only works with a caveat, the claim is too big for the format.

This is the same discipline that sits behind a pre-release advertising checklist, where the claim and its qualification are checked as one unit rather than two.

Testimonials, reviews and user content

Scheduled posts that reuse customer reviews must reflect genuine, current opinion. A review from 2023 used in a 2026 campaign may misrepresent the product as it now stands.

Influencer content the brand controls is the brand's claim. Scheduling it through an agency does not move responsibility away from the advertiser.

Substantiation and compliance duties before a post is queued

Evidence that a claim is true is what we call substantiation. The CAP Code puts the burden on the advertiser: if the ASA asks, you must hold the evidence before the claim runs, not assemble it afterwards.

For a scheduling team this means evidence is a release gate, not a filing task. A claim without a named evidence holder and a document reference should not enter the queue.

What counts as adequate evidence

Evidence needs to match the claim's scope. A claim about a UK-wide result needs UK-wide data, not a single-region trial. A claim about a percentage needs a sample size and a period.

Evidence also needs to be current. Market conditions, prices and product formulations change, and stale evidence stops supporting a live claim.

Keep the evidence in a place the scheduler or approver can reach during the approval step. A folder nobody opens at 5pm on a Friday is not a control.

The approval chain for scheduled claims

That record is what turns a scheduling platform into an audit trail. It is also the material you would hand to a regulator if a post is challenged months later.

Where the duties sit across a team

Marketing owns the claim. Compliance owns the evidence standard. The agency owns the accuracy of what it schedules on the brand's behalf. None of these can be delegated to a tool.

A scheduler can enforce a workflow, hold a version history and prevent release without approval. It cannot judge whether a claim is true. Teams that blur that line tend to discover the difference during a complaint.

A documented disclosure procedure helps here, because it fixes who signs off a claim before the post leaves the queue rather than after.

How CMA consumer protection guidance and the DMCC Act 2024 bite

In the UK, the Competition and Markets Authority serves as the regulator for both consumers and competition. Its consumer protection guidance for businesses explains how it expects traders to behave, and GOV.UK publishes the consumer protection guidance collection that businesses and their advisers work from.

The CMA's interest in social advertising is commercial practice, not taste. A misleading post is a misleading commercial practice whether it appears on a billboard or in a paid story ad.

Enforcement was transformed by the Digital Markets, Competition and Consumers Act 2024. The DMCC Act 2024 gives the CMA direct enforcement powers over unfair commercial practices, including the ability to decide that a practice breaches consumer law and to impose penalties without a court route.

What the DMCC Act changes for social teams

The practical change is speed and cost. A CMA investigation that once meant a long court process can now conclude with a penalty decision. Budget holders notice that.

It also raises the stakes on drip pricing and on claims that omit material information. A scheduled post that shows a headline price without a mandatory fee is exactly the kind of practice the regime targets.

Green claims are another live area. Vague environmental wording without evidence is a misleading practice, and the CMA has been explicit that broad terms need qualifying.

Fake reviews and misleading omissions

Scheduled posts that quote reviews must not use invented or incentivised reviews presented as independent. This sits in the same misleading practices territory as false claims about a product.

Omissions count too. If a post promotes a subscription without making the recurring nature clear, the omission can mislead even though every stated word is true.

Where CMA and ASA overlap

A misleading price claim can breach the CAP Code and consumer law at the same time. The ASA may rule on the ad while the CMA considers the practice.

That overlap is why compliance sign-off should cover both regimes in one pass. Running two separate reviews invites a claim that passes one and fails the other.

Your scheduling tool's version history is useful evidence in both. It shows what was published, when, and in what form, which is often the first question asked.

Sanctions, non-compliant advertiser lists and Trading Standards referrals

The ASA's first move is usually a request to amend or withdraw an ad. Most advertisers comply, and the case ends there without a published ruling.

If the advertiser does not comply, the ASA publishes a ruling naming the advertiser and the ad. Rulings are public, indexed and searchable, and they are read by competitors, journalists and procurement teams.

The ASA also maintains a list of non-compliant online advertisers. Repeat offenders can be named there, and the list feeds referrals to Trading Standards, which can act under consumer protection law with powers the ASA does not hold.

What a ruling costs beyond reputation

A ruling creates a written record of the claim and why it failed. That record is awkward in a pitch, in a retailer negotiation or in a funding conversation.

For regulated sectors, a ruling can also attract the attention of the sector regulator. Financial promotions, health claims and gambling ads all sit under additional oversight.

Paid search and social platforms may also act on ASA rulings. Some restrict ads from advertisers with unresolved rulings, which turns a compliance failure into a media buying problem.

Why Trading Standards referrals matter most

Trading Standards sits within local authority regulatory services. A referral moves the matter from an industry self-regulatory process into a statutory one.

That shift changes the potential consequences, the timescales and the tone of correspondence. It is the point at which a scheduling mistake stops being a marketing issue.

Teams that treat ASA correspondence as optional should read the escalation path again. The failure scenarios that end in referral usually start with an ignored request to amend.

The pattern behind most sanctions

Most sanctions follow the same shape: a claim that was true when drafted, scheduled without a recheck, and published after the underlying fact changed. Price, stock and offer dates are the usual culprits.

The fix is procedural, not creative. A release gate that rechecks time-sensitive claims immediately before publication removes most of the risk.

Copy Advice and pre-publication checks for scheduled claims

The ASA offers Copy Advice, a free and confidential service that checks ads before they are published. It gives an opinion on whether a specific ad is likely to breach the codes, and the ASA publishes the Copy Advice service details for advertisers and agencies.

It is not a clearance or an approval, and it does not bind the ASA if a complaint later arrives. It is still the best cheap check available before a claim goes into a queue.

Use it for the claims that carry real risk: comparative claims, price claims with conditions, health or environmental claims, and anything that would be expensive to withdraw mid-campaign.

When to ask and what to send

Ask before the campaign is built, not the day before release. Copy Advice turnaround depends on workload, and a rushed request usually means a rushed answer.

Send the actual scheduled copy, including the qualification as it will appear, plus the evidence you hold. Vague requests get vague responses.

If the advice says the claim is likely to breach the code, change the claim. Arguing the point with a published code section in front of you rarely ends well.

A pre-release checklist for scheduled claims

Run these quality checks as a release gate rather than a review meeting. A gate blocks a post; a meeting produces a note nobody reads.

A worked example

A UK supplement brand schedules a post for a Monday morning slot. The copy reads: "Clinically proven to boost immunity in 7 days. Ends Sunday."

Three problems. The health claim needs evidence that matches the exact wording, and "clinically proven" is a high bar. The seven-day timeframe needs substantiation. The offer end date needs rechecking against the live promotion.

Copy Advice would likely flag the immunity claim as needing qualification and evidence. The scheduling fix is to rewrite the claim to what the evidence supports, attach the study reference, and add a release gate that rechecks the end date on the Friday before publication.

That is the whole discipline. Claim, evidence, qualification, recheck, record. Everything else is tooling.
