Advertising and compliance

Who is liable if an agency's advertising breaks the rules?

The agency writes the claim. The regulator writes to the firm whose name is on it.

The short answer

Under the UK advertising rules, primary responsibility for a marketing communication sits with the marketer, which is the firm whose service is being promoted rather than the agency that wrote the advertising. An agency carries its own obligation alongside that, not instead of it. For marketing email the Privacy and Electronic Communications Regulations reach the firm that instigated the send as well as the party that transmitted it.

Key takeaways

  • The Committee of Advertising Practice Code puts primary responsibility for observing it on the marketer, with agencies and publishers obliged alongside.
  • Advertising Standards Authority rulings go onto the public record and are indexed under the advertiser's name.
  • Regulation 22 catches whoever instigates an unsolicited marketing email, not only whoever presses send.
  • The Information Commissioner's Office says enforcement would usually be taken against the instigator, which is the firm being promoted.
  • A firm can delegate the drafting. It cannot delegate being the advertiser, so the evidence for a claim has to be held at the practice.

A UK recruitment agency signs off a campaign in outline and leaves the wording to the agency it has hired. The landing page goes up and the paid search runs. Eleven weeks later a letter arrives, addressed to the recruitment agency rather than to the people who wrote the page.

That order of events is ordinary. In March 2019 the Information Commissioner's Office issued a £40,000 penalty against Grove Pension Solutions Ltd over 1,942,010 marketing emails. A specialist marketing agency had sent every one of them on the firm's behalf, and the recipients had given consent. They had given it to the companies holding the lists rather than to the firm being promoted, and the firm being promoted is the one that paid.

So the question worth asking before a campaign is approved is not whether the agency knows the rules. It is which of the two of you the regulator writes to when it turns out somebody did not.

The advertiser is the firm, not the agency that wrote the advert

The Committee of Advertising Practice Code states that primary responsibility for observing the Code falls on marketers, and that others involved in preparing or publishing marketing communications, such as agencies and publishers, also accept an obligation to abide by it. That is a structure of two obligations rather than a transfer of one. The marketer is the party whose product or service the advertising promotes, which for a UK practice means the practice.

The Advertising Standards Authority says the same thing about the evidence when it explains how the system works: marketers bear principal responsibility for what they produce and must be able to prove the truth of their claims. The party that has to hold the proof is not the party with the copywriters.

Four ordinary marketing acts, and who the rules name
The marketing actWho the rules treat as responsibleWhat the agency owes alongside
A claim on the firm's own websiteThe firm, as the marketer whose service is promotedAn obligation under the Code to create accurate advertising
A paid search advert the agency buys and managesThe firm being advertisedIts own obligation as the party preparing and placing it
A marketing email sent from the agency's own platformThe firm, as the instigator under regulation 22Its own liability as the party transmitting it
A post the agency publishes on the firm's social accountThe firm, whose account and name carry itAn obligation as the party preparing the material
No row moves the firm out of the middle column. Hiring well changes the likelihood of a problem. It does not change who answers for one.

What a ruling actually does to a firm

Advertising Standards Authority rulings are published on the public record and indexed under the advertiser, so the lasting cost is usually the search result rather than the correction. The rulings archive is open and searchable by company name. It also carries a separate list of organisations that agreed to amend or withdraw advertising without a formal ruling.

Where a UK firm does not comply, the Authority's published sanctions escalate past the ruling itself. Media owners can be asked to withhold advertising space, search providers can be asked to remove paid advertising, future marketing can be made subject to pre-vetting, and the Authority can place its own paid search advertising naming the advertiser. Persistent cases can be referred to Trading Standards or the Competition and Markets Authority. There is also a standing list of non-compliant online advertisers.

Marketing email reaches further than the agency's outbox

Regulation 22 of the Privacy and Electronic Communications (EC Directive) Regulations 2003 prohibits a person from transmitting, or instigating the transmission of, unsolicited communications for the purposes of direct marketing by electronic mail without the recipient's prior consent. The two verbs are the whole point. The party that presses send is caught, and so is the party that asked for it.

The Information Commissioner's Office is explicit about what that means when the work is outsourced. Its guidance on electronic and telephone marketing states that where a firm asks another organisation to send its marketing, both are responsible, and that enforcement action would usually be taken against the instigator. A firm is likely to be instigating if it encourages or asks somebody else to send its marketing.

Which returns to the pensions case, because it failed in the least obvious way available. Consent existed. It was held by the list owners and it had been given for marketing. What it was not was consent to hear from the firm whose service the emails promoted, because that firm was never named when it was collected. Four questions would have surfaced that before a single message went out.

The consent provenance test, and the answer that fails it
  1. Who collected these addresses, by name?

    Fails where nobody at the firm can name the collecting party, because the firm cannot then check what was said at the point of collection.

  2. What were those people told they were consenting to receive?

    Fails where your firm was not among the parties named. Consent to marketing in general is not consent to marketing from you.

  3. On what date was each consent given?

    Fails where the answer is a range rather than a date per record, which usually means the underlying evidence was never supplied.

  4. Can the firm obtain the consent record today, without asking the agency to ask somebody else?

    Fails where the record sits only with a list vendor.

Ask all four before the first send, not after the first complaint. Question two is the one the pensions case turned on.

What can be delegated, and what cannot

A firm can delegate the drafting and the placement. It cannot delegate being the advertiser. What that changes sits inside the practice rather than inside the agency.

Two documents carry most of the weight. The first is a written allocation of responsibility, which belongs with the paperwork that should exist before an agency starts work. The Commissioner's own guidance recommends a contract setting out the contractor's responsibilities and suggests asking for an indemnity against a breach.

The second is duller and more useful: a claims file the practice keeps itself. For every factual statement the advertising makes, the firm holds the evidence and the date it was checked. Where a claim rests on the agency's word, the practice is standing behind something it cannot produce, and the standard the firm can otherwise hold an agency to is set out in what a firm can hold an agency to when results do not come.

Before the next campaign goes live

Not sure who is answerable for the advertising running now?

Free to your firm. The agency pays us, and only if the relationship works, which is why we would rather spend an hour on your claims file than introduce somebody who writes copy your practice cannot support.

When a firm should not be commissioning advertising yet

If nobody at the practice can approve a claim on the day it is needed, the campaign will either stall or publish unapproved, and both outcomes belong to the firm. Fix the approval route before buying the media.

The harder case is a firm that wants a claim it cannot evidence. A practice that wants to advertise a turnaround time it has never measured is not short of an agency, it is short of a measurement, and an agency paid to make the claim land is poorly placed to talk it out of one. Three things have to exist before the money is committed: the claim, the evidence for it, and the person at the firm who signs both off.

An agency that never asks who holds the evidence is showing you something early, which is one of the signals worth walking away from. Partners who would rather test that before appointing anyone can see what we assess before recommending an agency.

Frequently asked questions

What partners ask when the advertising is somebody else's work.

Is the agency liable if the agency wrote the misleading claim?

The agency carries its own obligation under the Committee of Advertising Practice Code. What it cannot do is take the firm's place: primary responsibility for observing the Code sits with the marketer, which is the party whose service is being promoted.

Does an Advertising Standards Authority ruling name the agency or the firm?

Rulings are published on the public record and indexed under the advertiser. A UK partner can search the archive by company name, which also means a prospective client or a competitor can search it for theirs.

Who is responsible for a marketing email an agency sent on our behalf?

Both parties. Regulation 22 of the Privacy and Electronic Communications (EC Directive) Regulations 2003 reaches whoever instigates an unsolicited marketing email as well as whoever transmits it, and the Information Commissioner's Office says it would usually enforce against the instigator.

Can a contract move advertising liability onto the agency?

It can allocate cost between the two businesses, and an indemnity is worth having. It does not change who the regulator writes to, because the Code and the Regulations identify the responsible party by what it is rather than by what a contract says it is.

What should a firm keep on file before a campaign runs?

The evidence for every factual claim the advertising makes, held by the firm rather than only by the agency. If a claim cannot be supported from the practice's own records, the campaign is asking the firm to stand behind something it cannot prove.
