How to review an agency's creative-tool service without manufacturing a score

Review the service the agency will deliver, not the logo on its proposed software stack. The useful unit is one live brief traced through production, approval, release, correction and exit.

What to take away

Scope and disclosure

This article sets a method; it does not rate named agencies. Desk research ended on 5 September 2026. The draft author and qualified reviewer remain unassigned. No agency supplied access, hospitality, references, payment or a sample project. Nobody interviewed staff, contacted clients or observed delivery, so there is no hands-on verdict to report.

A qualified reviewer means a named person with direct experience of advertising production and contract review who did not write the draft and has no commercial interest in the agency. Qualified scrutiny means that reviewer has checked the live brief evidence and the contract terms against the method in this article.

The operating context is an organisation in England. UK registers and guidance keep their stated national scope. Public-sector sourcing material is used only for adaptable process questions.

Verify the contracting party

Ask for the legal name, company number, trading names, insurance and the entity that will invoice. Check the Companies House register for the current filing record and document images. Companies House warns that it does not verify the accuracy of filed information, so the search is an identity check rather than proof of capability or solvency.

Professional membership can be confirmed with the relevant body. The IPA member directory lists member and accelerator agencies and was updated in February 2026. Membership is neither a ranking nor a complete list of capable UK agencies.

Review the proposed team and workflow

Require names, roles, allocation and cover for the people who will do the work. Ask which tasks are performed by the agency, subcontractors, the tool supplier and the client. A senior pitch team should not be treated as the delivery team unless the commitment is written.

Provide a realistic brief with awkward copy, rights limits, a missing feed value and a late correction. Observe the agency creating a version register, routing qualified review, handling the exception and preparing withdrawal. Record interventions. A rehearsed demonstration using the agency's ideal specimen is useful orientation, not buyer evidence.

For example, the brief might include the headline "Grab yours now" beside a product name, a price feed that returns a blank for one size, and a legal correction arriving after approval. The agency should log the version, flag the missing value, route the corrected line to the named approver and record who signed it off.

Examine references without manufacturing a score

Seek references with similar workload, risk and channels. Obtain permission to ask about missed deadlines, staff changes, disputed scope, incident response and exit. Record who selected the referee and what could not be checked.

If consumer review pages are considered, distinguish genuine, incentivised and unverified material. The CMA's guidance for businesses and agencies explains the current UK position on fake and concealed incentivised reviews. Its application needs legal review.

The CMA's online consumer reviews case page also records open investigations; suspicion must not be reported as a finding of infringement. Preserve the publication date and case status whenever such material informs diligence.

Put delivery promises into the contract

Define the accepted brief, output inventory, approval authority, service hours, correction route, audit trail, data roles, asset ownership, subcontractors and termination assistance. Separate a target from a remedy. Require an inventory and export test before signing where lock-in would be costly.

Illustrative remedy wording: "If the agency misses the agreed correction window, the client may withhold acceptance of that deliverable until the correction is logged and approved."

The Cabinet Office Sourcing Playbook gathers current public-sector material on evaluation, testing and supplier viability. It binds central-government work within its scope, not a private agency purchase, but it demonstrates why evidence should be planned before bidder claims are scored.

Record a conditional verdict

Conclude with verified facts, observed evidence, contractual commitments and open questions in separate sections. State which named person reviewed each. Until the live brief and terms have passed qualified scrutiny, use "candidate for the next stage" rather than recommended agency.

Before you act

Common questions

What should a buyer review instead of the agency's proposed software stack?

Trace one live brief through production, approval, release, correction and exit, and check the assigned team's handling rather than the proposed stack.

What does a Companies House search actually prove about an agency?

It is an identity check rather than proof of capability or solvency. Companies House warns that it does not verify the accuracy of filed information. Ask for the legal name, company number, trading names, insurance and the entity that will invoice, then check the current filing record and document images.

How should consumer review pages be treated during diligence?

Distinguish genuine, incentivised and unverified material. The CMA guidance explains the current UK position on fake and concealed incentivised reviews, and its application needs legal review. The CMA case page records open investigations, but suspicion must not be reported as a finding of infringement.
