The Scar, Not the Silverware: Rethinking How UK Firms Take Consultancy References

Most reference checks in UK professional services are a formality dressed as diligence. A buyer rings two names supplied by the adviser, hears that the work was excellent and delivered on time, thanks the referee, and files a note. The exercise establishes that the adviser has at least two clients willing to say something warm. It establishes almost nothing about month four, when the model does not reconcile and the executive sponsor has moved on.

There is a better question, and it is rarely the one asked. Rather than requesting the flagship success — the trophy — ask the referee to describe a project that slipped.

The trophy question and why it tells you so little

A flagship case study is a curated artefact. By the time it reaches a pitch document it has passed through several rounds of editing: the timeline has been smoothed, the awkward fortnight in February compressed into a phrase like a period of adjustment, and the commercial outcome stated in whichever unit flatters the work — a percentage uplift, a headcount saved, a decision accelerated by six weeks. None of this is dishonest. It is simply the wrong instrument for the question the buyer is actually trying to answer.

That question is not whether the firm can produce a good outcome. It is how the firm behaves when the outcome is in doubt. These are different competencies, and only one of them can be assessed from an account of success that has been polished for reuse.

What a slipped project exposes

A project that went off course — modestly, recoverably, but genuinely — reveals operating habits that no case study can. It shows whether the adviser noticed the drift or had to be told. It shows whether the correction was surfaced early, in a form the client could act on, or arrived late and wrapped in framing. It shows whether the cost of putting things right was absorbed, shared, or quietly added to a subsequent invoice. And it shows whether the referee, speaking a year later, still sounds sour about it.

A referee who can talk plainly about a near-miss, in detail, without disparaging the adviser, is usually describing a relationship that survived contact with reality. That is a more valuable asset than an unblemished testimonial, because most engagements of any length will encounter at least one moment where reality intrudes.

Three questions worth asking

The structure matters less than the permission. Buyers often receive evasive answers not because referees are concealing something but because nobody has invited candour. A short, matter-of-fact preface does most of the work: we are trying to understand how the firm operates when things move, not to audit the outcome.

First: tell us about a piece of work that went off plan. Not badly, not catastrophically — off plan. Referees who have been asked this before will have an answer ready. Those who have not may pause, which is itself informative. Listen for whether the slippage is described in specifics — a missed dependency, a stakeholder who disengaged, a data set that proved unusable — or in comfortable generalities.

Second: what changed, and who noticed first? The second half of that question is the one that matters. An adviser who noticed first, raised it unprompted and brought a proposed adjustment is exhibiting precisely the behaviour the fee is meant to buy. An adviser who was told, twice, and then responded well is still competent, but is being managed by the client rather than managing the work. Both can be acceptable. The buyer should at least know which one is on offer.

Third: how was the correction paid for? Commercial honesty under strain is the hardest thing to test and the easiest to test badly. The question is not an invitation to litigate an invoice; it is a request for the principle. Was the overrun absorbed, shared, re-scoped or billed? Did the adviser propose the arrangement or simply accept it? Referees remember this clearly, and their tone when answering tells you as much as their words.

Reading the answer

Three patterns are worth flagging.

The first is the referee who cannot recall a single instance of slippage across a long relationship. That is possible on narrow, tightly defined work, but on advisory engagements of any duration it is unusual. More often it means the referee was not close enough to delivery to see the wobble, or that the relationship is being presented rather than described.

The second is the answer that relocates all difficulty to the client: the brief changed, the sponsor left, the data arrived late. Some of that will be true. But an adviser whose every account of difficulty begins with the client's failings is telling you something about how it will narrate your engagement once you are no longer in the room.

The third, and the most useful, is the referee who volunteers a specific moment, names their own part in it, and describes a correction both parties agreed. That answer is difficult to fabricate and easy to test with one follow-up: what would you do differently if you commissioned the same work again?

Weighing candour against polish

There is a temptation to treat a candid near-miss as a mark against the adviser and a flawless record as a mark for. Reverse the instinct. A near-miss described with precision is evidence of a working feedback loop; a spotless record is evidence of a well-maintained narrative. The aim is not to prefer failure but to prefer firms that can see it coming and say so.

None of this means discounting success. A firm that has never hit trouble on a particular type of engagement may simply be well suited to it. But the buyer should notice which of the two they have been shown, and weight accordingly — particularly where the engagement is complex, lengthy, or dependent on internal stakeholders the adviser cannot control.

Making the habit stick

Three practical adjustments help. Ask for referees whose work resembles your engagement in shape rather than in prestige: a similar scope, a similar governance structure, a similar level of internal maturity. Take the reference before the final decision rather than after a preferred supplier has emerged, while the conversation can still change the outcome. And record the answers in a comparable form across candidates, because the difference between two referees' accounts of difficulty is often more revealing than either account alone.

One further discipline is worth adopting: ask referees which of their own colleagues would give the least flattering account of the work, and then ask whether that person is available. Few buyers take this step. Those who do tend to learn more in twenty minutes than they would from a full pitch cycle.

A closing note

Reference checks remain one of the few genuinely cheap forms of diligence available to a UK buyer of specialist advice. They cost an hour and a conversation. Spending that hour on the trophy is a missed opportunity; spending it on the scar is modest insurance against a considerably more expensive surprise.
