Buyers price what they can verify
Every valuation conversation starts with a number and ends with a spreadsheet. The number is the multiple: what a buyer says they will pay per pound of recurring income. The spreadsheet is where that number is tested against your actual records, client by client, plan by plan, fee line by fee line. Whatever you believe your firm is worth, the price you complete at is built from the data a buyer can verify, not the data you carry in your head.
This is the part of the process that surprises owners most. You know your clients. You know that Mrs so-and-so has been with you for twenty years, that her review happened in March even though nobody wrote it up, that the platform fee schedule changed in 2023 and most clients moved across. The buyer knows none of this. The buyer knows only what your systems can show them, and where the systems are silent, the buyer assumes the worst, because assuming the worst is what their investment committee and their lenders require them to do.
The result is a simple and slightly brutal equation. Verified recurring income gets the full multiple. Unverifiable income gets a discount, an earn-out condition, a deferred consideration holdback, or is excluded from the price altogether. The difference between a firm that completes at the top of the range and one that completes at the bottom is very often not the quality of the advice; it is the quality of the records that prove the advice happened.
Why diligence has become harder to pass
Two forces have raised the bar. The first is who is buying. The most active acquirers in this market are private-equity-backed consolidators and national firms, and who is buying UK advice firms in 2026 matters here because these buyers run institutional diligence processes. Their funding depends on it. Lenders and investors behind an acquisition want evidenced income, not asserted income, and the diligence team's job is to find every pound that cannot be evidenced.
The second is the regulator. The FCA's expectations of firms selling client banks, first published in December 2023 and updated in January 2025, make clear that the client bank is the firm's asset and that the FCA will act where client banks are sold with redress liabilities left behind. Its multi-firm review of consolidation in the advice and wealth management sector, published on Fri 31st Oct 2025, pressed acquirers on governance and risk management in exactly the same breath. A buyer absorbing your back-book is absorbing your conduct risk, and the only way they can size that risk is through your files. Thin files mean unquantifiable risk, and unquantifiable risk gets priced with a wide margin of safety, at your expense.
It is worth saying that the market itself is not the problem. Gunner & Co reported average recurring-income multiples of 4.2x in the first half of 2025, the highest point since 2018, and named competition for well-prepared firms as one of the drivers. Well-prepared is the operative phrase. The premium is real, and it goes to firms whose data survives contact with a diligence team.
The specific fields buyers test
Diligence on an advice firm is not a vague rummage through your filing. It is a structured reconciliation exercise, and it concentrates on a predictable set of fields. Knowing them in advance is most of the battle.
FUM per client. The buyer will take your client list and reconcile funds under management line by line against platform and provider statements. Every client should have a current FUM figure that matches an external source. Gaps appear where legacy holdings sit off-platform, where a client moved providers and the CRM was never updated, or where a figure was keyed in three years ago and never refreshed. Each unreconciled line becomes a question, and a data room that generates hundreds of questions is a data room that slows the deal and softens the price.
Fee schedules and actual fees collected. What each client is charged, on what basis, and what was actually received over the last twelve to twenty-four months. Buyers compare the stated fee schedule to the cash that arrived, because the difference exposes clients on legacy terms, fees that were agreed but never implemented, and income that depends on arrangements a buyer cannot inherit cleanly. Recurring income is the foundation of the price, as covered in recurring income multiples explained, so anything that muddies what counts as recurring gets stress-tested hardest.
Contact recency and review records. When each client was last spoken to, when their last review took place, and whether the file evidences it. Under the Consumer Duty, an ongoing advice fee needs an ongoing service behind it, and a buyer will test whether yours is documented. A review that happened but was never written up is, for pricing purposes, a review that did not happen. Clients with no recorded contact for two years or more will be flagged, and the income attached to them will be treated as at risk.
Vulnerability flags. Buyers now check whether vulnerable clients have been identified and whether the firm's records show any assessment at all. A client bank with no vulnerability markers whatsoever does not read as a client bank with no vulnerable clients; it reads as a firm that never looked. That is a conduct finding waiting to be made, and it lands in the warranties, the indemnities, or the price.
Client age and concentration. Date of birth for every client, so the buyer can model decumulation and mortality across the book, and income concentration, so they can see how much of the recurring line depends on the top ten clients. Missing dates of birth are a small omission with a large effect, because a buyer who cannot age your book will assume it is older than it is.
Where the discounts come from
The mechanics are worth understanding, because the damage rarely arrives as a single headline reduction. It arrives in pieces.
Income the buyer cannot verify gets carved out of the recurring line and either excluded or made conditional. The orphaned back-book is the classic case: clients paying ongoing fees who have had no documented service for years. A buyer will not pay a full recurring multiple for income they may have to refund, so it moves into an earn-out or a deferred tranche, payable only if the clients are contacted, re-served and retained. You still might receive that money, but you now carry the risk of it, often over a period commonly running many months, and deferred consideration needs protecting in ways an up-front payment never does.
Gaps in review evidence produce warranty and indemnity demands. Where the buyer cannot see that ongoing service was delivered, they will ask you to warrant that it was, and to indemnify them if a redress exercise later says otherwise. Your liability for past advice does not vanish at completion in any structure, but poor records widen what you are asked to stand behind and lengthen how long you stand behind it.
And in the worst cases, the deal simply dies. Diligence fatigue is a real killer of transactions: a buyer who spends three months chasing reconciliations loses conviction, their board loses patience, and the deal joins the list of deals that collapse for reasons that were entirely fixable a year earlier.
What a clean data room looks like
For an advice firm, a clean data room is not a mountain of paper. It is a small number of documents that reconcile with each other and with external sources.
- A single client schedule: every client with FUM, fee basis, annual recurring income, adviser, date of birth, last review date and last contact date, exported from the CRM, not built by hand for the sale.
- Platform and provider statements that tie back to that schedule, so FUM and income reconcile line by line.
- Fee agreements and ongoing service agreements for every client paying an ongoing fee, with the current terms, not the terms from three fee schedules ago.
- Review packs or file notes evidencing the last review cycle for every ongoing-service client, plus a documented position on any client outside the cycle.
- A vulnerability register, complaints log and PI claims history, even where the entries are nil, because an evidenced nil is worth far more than a blank.
The phrase that matters in that first item is exported, not built. Buyers can tell the difference between a schedule generated from a living system and one assembled in a spreadsheet the month before the process started. The first says the firm runs on data; the second says the data was reverse-engineered for the sale, and everything in it will be checked twice.
Start earlier than feels necessary
None of this can be fixed in the fortnight before heads of terms. Reconciling FUM, re-papering fee agreements, contacting dormant clients and rebuilding review evidence is months of work, which is why data quality sits at the centre of the 24-month plan to sell your practice. The firms achieving the strongest prices in the current market are not the ones with the most polished pitch documents; they are the ones whose CRM answers a diligence question in an afternoon rather than a month.
There is also a quieter benefit. The exercise of cleaning your data tells you, before any buyer does, what your firm is really worth. You will find the orphaned clients, the legacy fee terms and the income that would not survive scrutiny, and you can decide what to do about them while they are still your problem to solve on your own terms. The rest of the getting sale-ready pillar covers what buyers ask for and in what order; the data work is the part that makes every other answer credible.
