What service standards mean for buying copywriting services

What to take away

What changed, and why it matters now

IAB UK published its Search Principles for creative best practice, and they took effect on 1 February 2026 following a six month grace period. The principles cover how search copy is written, labelled and evidenced. For buyers, service standards have moved from a private preference to a documented expectation you can point to in a contract.

Publishing rules have tightened too. The Advertising Standards Authority can require an advertiser to amend or withdraw non-compliant copy. The CAP Code copy guidance explains how claims, comparisons and endorsements should be handled.

A supplier that treats that guidance as part of the brief is easier to defend than one that treats it as an afterthought.

What a written standard actually contains

A usable standard answers five questions. Who signs off copy before it goes live? What evidence supports each claim? How are labels and disclosures applied? Where is the approval record kept? Who owns the review date? A standard without a named owner is a wish, not a control.

Where the risk sits in the workflow

Most failures are handover failures. The researcher writes one thing, the writer changes it, the client edits it, and nobody checks the claim again. Build one approval step after the last edit. Record the approved version.

If you are still shaping the delivery model, the operations and delivery guide shows how briefs, drafts and sign-off fit together across a year.

How to set standards you can enforce

Start with the rules that already bind you, then add your internal standard. That order matters. A standard that contradicts a regulator creates work instead of reducing it.

The ICO's guidance on choosing a lawful basis for direct marketing explains why consent and legitimate interests are not interchangeable, and why the choice should be made before content is sent. The rules behind it sit in the UK GDPR, the Data Protection Act 2018 and the Privacy and Electronic Communications Regulations, which govern electronic marketing in the United Kingdom.

The standards to write into the brief

Agree these in writing before the first brief, and carry each one into the statement of work: turnaround times and the approval window; how many revision rounds are included and how extra rounds are handled; who owns the copy and when ownership transfers; confidentiality on both sides; accessibility, including WCAG conformance for web copy; and the SEO requirements the copy must meet, such as target queries and metadata.

Name the clauses that carry them: scope and deliverables, acceptance and approval times, revisions, intellectual property assignment on final payment, confidentiality, and termination. A supplier can only be held to a standard the contract states.

The four checks to run on every brief

Check	Question to ask	Evidence to keep

For example, a team paying £400 a month for outsourced copy can still run all four checks in under an hour. Keep them on one page so they survive contact with a busy week.

How to test a supplier against it

Before you commission, ask for two things: a recent sample of approved copy with its source list, and the name of the person who signs off.

Compare the supplier's process with your own approval step. Where they disagree, agree in writing which governs and note it in the statement of work.

If the engagement is new, a launch review is a sensible way to test the process on live work before you scale spend.

Keeping standards alive after launch

Standards decay quietly. A writer leaves, a template is reused, and a disclosure disappears. Put a quarterly sample review in the calendar: pull ten published pieces, check them against the four checks, and log the result. IAB UK's search creative best practice principles give you an external reference point for the search elements when you do that review.

What to record each quarter

Record the number of pieces sampled, the number that failed a check, the fix applied, and the date. Two or three lines per quarter is enough. The record matters more than the format, because it shows a pattern of control rather than a single good intention.

When to escalate

Escalate when the same check fails twice, when a regulator or platform contacts you, or when a claim cannot be sourced at all. Escalation should mean pausing publication, not rewriting quietly. A paused page costs less than a withdrawn campaign.

Common questions

Do these standards apply across the UK?

The CAP Code and the ICO's marketing rules apply across the United Kingdom. IAB UK's Search Principles are industry guidance for search creative rather than a statute, so treat them as a baseline your contracts can reference.

Do small advertisers need a written standard?

Yes, but keep it short. Four checks on one page, with a named approver, will cover most small teams. The risk is an unsourced claim or a missing label, not the length of the document.

Can a supplier's own standard replace ours?

No. Use theirs as an input, but your approval step still governs what you publish. Agree in writing which process wins where the two differ.

How often should the standard be reviewed?

Review it annually, and sooner if a regulator, platform or client contract changes. Add the review date to the document itself so it does not depend on memory.
