Evidence-honest review · qualifications stay visible · no invented proof or regulator approval

The problem

When a claim may be stronger than the evidence behind it

A claim does not need to be obviously false to create a problem. It may rely on a weak source, omit an important qualification, use a comparison with no clear basis, or turn an aspiration into a statement of fact.

This review is useful when you want to challenge the wording before release rather than discover afterwards that the evidence does not support what was said.

The outcome

What changes

You move from a page, proposal or campaign containing untested assertions to a structured record of each material claim, the evidence behind it and the action needed before release.

The review does not create proof that is not there. It makes the evidence position, qualifications, gaps and residual limits visible so your organisation can make its own publication decision.

Where this could lead next

This service is complete in its own right. You do not need another service for this one to be worthwhile. If the work uncovers a separate problem worth solving, these are the most likely next steps.

Research & Evidence Briefing Service

What needs to be in place?

A clear intended claim set, the customer-facing use or version it belongs to, and the underlying evidence and source material you want the review to rely on.

What is outside the scope?

Legal advertising clearance, regulator approval, formal audit or certification, a legal opinion, a guarantee of regulator acceptance, or invention of evidence that does not exist.

Is this the right service?

It fits an SME or charity preparing factual, comparative, performance or other evidence-dependent customer-facing claims and wanting an evidence-honest challenge before release.

What this service does not promise

No claim is certified lawful, regulator-approved or commercially effective. You retain authority for final wording, publication and any legal or specialist sign-off required for your circumstances.

FROM INTEREST TO A CLEAR DECISION

How to get started

Start with the problem, not a purchase decision. We will check whether this service fits before anything is agreed.

1. Tell us what is happening

Share the problem you are trying to solve, what you already have and any deadline or constraint that matters.

2. We check the fit

We check the scope, the information we would need, the fee and whether this is genuinely the right service. If it is not, we will say so.

3. You decide with the facts clear

Nothing starts until you know what is included, what is not, what you need to provide and what happens next.

There is no pressure to add another service. The useful next step is simply to decide whether this one solves the problem in front of you.

Next step

Which claims do you want challenged against the evidence?

Tell us where the claims will appear and what evidence sits behind them. We will first check whether this service fits and confirm the scope, timing and price before you commit.
