In a share sale, the buyer acquires your company, which keeps its contracts and liabilities. In an asset sale, the buyer acquires selected assets, usually client relationships and recurring income, while you keep the company. That choice affects client transfers, tax, past-advice liability and how the sale is paid for.
Before you talk about multiples, earn-outs or completion dates, there is one question that shapes everything else in the sale of an advice firm: are you selling the company, or are you selling what the company owns? A share sale transfers the legal entity itself, with everything inside it. An asset sale transfers specific things, usually the client bank and the recurring income attached to it, while the company stays with you. Almost every other feature of the deal, from the tax you pay to the liabilities you keep to the months the process takes, flows from that fork.
Most owners arrive at this decision late, after a buyer has already told them which structure is on the table. It is the first question in how firms are sold for a reason. That is the wrong order. Understanding the fork before the first serious conversation means you can negotiate structure as well as price, and the structure is frequently worth more than the headline number suggests.
What actually transfers in a share sale
In a share sale, the buyer purchases the shares of your limited company from you, the shareholder. The company itself does not change; only its ownership does. Every contract the company holds, every regulatory permission it carries if it is directly authorised, every employee it employs and every liability it has ever accrued stay exactly where they are, inside the company. The buyer now owns the box and everything in the box.
This is the crucial point that gets glossed over: liabilities travel with the shares. If the company gave unsuitable advice in 2019 and a complaint surfaces in 2028, that complaint lands on the company, which by then belongs to the buyer. The buyer knows this, which is why share purchase agreements come loaded with warranties and indemnities that reach back to you personally, often for years after completion. The company changed hands; the risk got contractually redirected. There is more on how those clauses work in warranties and indemnities in advice firm sales.
From the client's point of view, a share sale can be close to invisible. Their adviser agreement is with the company, and the company still exists. There is usually no need to re-paper client agreements or seek individual consent to the transfer of each relationship, because no relationship has legally transferred. The clients were with the company before, and they are with the company after.
What actually transfers in an asset sale
In an asset sale, the company sells specific assets to the buyer: typically the client bank, the servicing rights to the recurring income, perhaps the trading name, the office lease, some equipment. The company itself, and your ownership of it, do not move. The buyer takes the things it wants and leaves the rest.
The rest includes the liabilities. This is the single most important sentence in this article: in an asset sale, your company keeps its historic advice liability. The buyer acquires clients and income; it does not acquire responsibility for the advice your firm gave before completion. Complaints about past advice still come to your company, and your company must still be able to meet them, which is why run-off cover and adequate financial resources matter so much after an asset sale. The FCA is explicit on this point in its expectations of firms selling client banks, first published in December 2023 and updated in January 2025: it will act where client banks are sold with redress liabilities left behind and no credible means of meeting them, and firms are expected to hold adequate financial resources for potential redress. Selling the asset does not sell the obligation.
The practical consequence is that an asset sale is not an ending in the way a share sale is. Your company lives on, at minimum as a vehicle holding residual liability, often with run-off professional indemnity cover for a period of years. What that costs and how long you need it is covered in run-off cover: what it costs and how long you need it.
Consent and novation: why asset sales involve the clients
Because an asset sale transfers relationships rather than a company, the clients have to come along individually. Each client's agreement is with your firm; for the buyer to serve them, that agreement must either be novated, meaning formally replaced with a new agreement between the client and the buyer, or the client must otherwise consent to the transfer.
Consent mechanics vary. Some deals use positive consent, where each client actively signs up with the buyer. Others use a negative consent process, where clients are written to, told the relationship is transferring, and given a period in which to object; silence is treated as agreement. Negative consent moves faster and loses fewer clients through inertia, but the process has to be handled carefully and communicated honestly, and the FCA's expectations around treating clients properly through a transfer apply in full. Either way, the client hears about the sale, engages with it, and can walk away. That is a structural difference from a share sale, where the transfer can complete before most clients notice anything has happened.
This is also why asset sale consideration is so often staged. The buyer does not know on completion day how many clients will actually transfer and stay, so a meaningful part of the price is typically deferred and adjusted against the recurring income that actually arrives. Clawback provisions, where consideration reduces if clients leave within a defined period, are standard. The mechanics of protecting that deferred money are a subject in their own right; see deferred consideration and how to protect it.
Why buyers often prefer assets and sellers often prefer shares
The pattern in the market is consistent enough to state plainly. Buyers, particularly the larger acquirers, often prefer asset purchases. Sellers, given a free choice, often prefer share sales. Both preferences are rational, and they point in opposite directions.
The buyer's case for assets is about risk hygiene. An asset purchase lets the buyer take the client bank and the recurring income without inheriting an unknown quantity of historic advice liability, legacy systems, employment history and whatever else sits in a company that has traded for twenty years. Due diligence on an asset deal can concentrate on the quality of the client bank and its income; due diligence on a share deal has to interrogate the whole corporate history, because the buyer is acquiring all of it. For a buyer completing many acquisitions a year, buying assets keeps each deal clean and repeatable.
The seller's case for shares is about finality and tax. A share sale gives you a clean exit: the liabilities go with the company, moderated by whatever warranties and indemnities you sign, and there is no residual entity to run off. The proceeds arrive as a personal capital gain on your shares, which is generally the most straightforward tax outcome and the one Business Asset Disposal Relief was designed for. In an asset sale, the company receives the money, pays corporation tax on the gain, and you then face a second tax event extracting the proceeds from the company. Two layers instead of one, unless the company is subsequently wound up in a way that allows capital treatment on the distribution. The full comparison, with the current rates, is worked through in the tax pillar's dedicated piece on the asset versus share sale tax comparison; the headline is that from Mon 6th Apr 2026 Business Asset Disposal Relief taxes qualifying gains at 18 per cent, per gov.uk's published rates, and a well-structured exit in either form can still reach relieved capital treatment, but the asset route requires more steps to get there.
Neither preference is absolute. A buyer will do a share deal for a firm whose corporate history is clean, well-documented and worth the diligence effort, and some buyers price shares generously precisely because most sellers want them. A seller can rationally prefer an asset sale where the company has known historic issues that would poison a share negotiation, or where only part of the business is being sold. And the widely used route of a structured asset sale to a national acquirer is an asset transaction by design, with its own logic around retained income commonly running many months. The point is not that one structure is good and the other bad; it is that each allocates risk, tax and effort differently, and you should know which allocation you are accepting.
How the choice shapes the regulatory path
The regulatory workload differs too. In a share sale of a directly authorised firm, the buyer is acquiring control of an FCA-authorised entity, which triggers the change in control regime: the buyer must seek FCA approval before completing, and that approval has its own statutory clock. In an asset sale, there is no change in control of your firm, but the FCA still expects to be told. A sale of the client bank that could affect your firm's risk profile, value or resources calls for a notification under SUP 15, and the regulator's client bank guidance makes clear that the client bank is the firm's asset, that claims someone else owns it need proof, and that legitimate reasons for sale include merger and retirement. What the regulator looks for through the whole process is set out in the FCA's expectations when a client bank is sold.
For appointed representatives the fork looks different again. An AR's clients formally belong to arrangements sitting under its principal, so an AR exit is almost always an asset-shaped transaction in substance, and the principal's consent and cooperation become part of the deal mechanics. If you run an AR, the share sale route in its clean form is often simply not available in the way it is for a directly authorised firm.
How the choice shapes the timeline
Timelines follow the structure. A share sale's long pole is usually due diligence and, for a directly authorised firm, the change in control approval; the client-facing work is light. An asset sale's long pole is the client transfer itself: writing to every client, running the consent period, novating agreements, moving the servicing of each plan, and then living through the earn-out or clawback window while the income proves itself. A share deal tends to be heavier before completion and lighter after; an asset deal is often quicker to sign but keeps working long after completion day, because the price is still being earned as clients transfer and stay.
Neither route is fast. Diligence, negotiation, regulatory steps and client work each take months, and they overlap rather than queue neatly. Realistic expectations for the whole journey are set out in how long a sale actually takes.
Deciding which fork is yours
The honest answer for most owners is that the structure will be negotiated, not chosen freely, because the buyer's model matters as much as your preference. But you negotiate better knowing what each structure costs you. Three questions get to the heart of it quickly. First, what does your company's history look like under a microscope: a clean file supports a share sale, a complicated one pushes towards assets. Second, how much do you value finality: a share sale ends it, an asset sale leaves you running off a company and its liabilities. Third, what does the after-tax comparison say on your actual numbers, not in general, because the gap between one layer of tax and two can outweigh a meaningful difference in headline price.
Structure and price are traded against each other in real negotiations. A buyer offering a share purchase with heavy warranties, or an asset purchase at a stronger multiple with the liability staying behind, is offering you different bundles of money and risk, and the right comparison is net proceeds after tax and after the cost of the risk you retain.
