Why sell-side only matters
In UK SME M&A, many advisers act for both sellers and buyers across different deals. That model creates structural conflicts: relationships with active acquirers and funds shape who hears about your business, on what terms, and how hard your position is defended in negotiation.
Mergers does not work that way. We are a strictly sell-side firm. We only act for UK business owners and founders. We never represent buyers, investors or incoming partners. There is no parallel mandate, no introducer fee from a buyer, and no commercial interest in any acquirer's pipeline.
This is not a minor administrative detail. Consider the mechanics of a typical mixed-model advisory relationship. A firm that acts for buyers builds ongoing relationships with the private equity funds, trade consolidators and strategic acquirers who are active in a given sector. Those relationships are commercially valuable to the adviser because buy-side mandates and repeat introductions generate fee income independent of any single sell-side deal. When the same firm then represents a seller in a transaction involving one of those buyers, or a buyer the firm hopes to work with in future, there is at minimum a perception problem, and at worst a genuine tension between defending the seller's price and preserving a relationship the firm values for other reasons.
The result of removing that tension entirely is straightforward: your adviser sits entirely on your side of the table, every time, on every mandate, with nothing else to protect.
Who we act for, and who we do not
We act for
- UK SME founders and majority shareholders considering a partial sale
- Owner-managers exploring a majority sale while staying involved
- Founders planning a two-stage exit with continued upside
- Shareholders weighing trade buyer, strategic partner or private equity routes
We never act for
- Buyers, acquirers or trade consolidators
- Private equity funds, family offices or institutional investors
- Incoming strategic or growth partners
- Search funds, MBI candidates or independent sponsors
This list is deliberately broad. It is not enough to avoid acting for the specific buyer in a live deal; a genuinely sell-side-only firm avoids the entire category of buy-side work, because it is the ongoing pattern of buyer relationships, not any single transaction, that creates the structural conflict founders should be alert to when choosing an adviser.
What sell-side only means in practice
On every engagement, our duty is to the selling shareholders. We prepare the business for sale, identify and approach suitable acquirers, manage competitive tension, negotiate heads of terms and support legal completion. The full sell-side process is run on the founder's behalf, end to end.
We do not accept introducer or success fees from buyers, funds or partners. We do not maintain buy-side mandates. We do not run a directory, deal board or marketplace. Acquirers approach our process on the founder's terms, not the other way round.
In practical terms this affects several stages of a transaction. During buyer research, the target list is built entirely around what suits the seller's objectives, whether that is maximising price, finding a genuine strategic fit, or identifying a partner suited to a two-stage exit where the founder retains equity and sells the remainder later. During negotiation, there is no incentive to steer terms towards a buyer relationship the adviser values for other reasons. During due diligence, the adviser's role is to help the seller respond to buyer requests efficiently, not to manage the process on the buyer's behalf.
This positioning shapes everything from how we discuss valuation to how we negotiate protections in shareholder agreements.
Why this matters more for partial sales
A partial business sale, whether it is a minority stake sale or a majority stake sale where the founder stays involved, is a more complex transaction than a clean full exit. The founder is not just negotiating a price; they are negotiating an ongoing relationship with the incoming partner, covering governance, reserved matters, dividend policy, future funding rounds and the mechanics of any second-stage sale.
In that context, conflicts of interest are more consequential, not less. A founder retaining 30 or 40 per cent of their business and continuing as managing director needs an adviser who is entirely focused on getting the shareholders' agreement right, on ensuring the retained equity is genuinely protected, and on stress-testing how the relationship with the incoming partner will work in year three, not just at completion. An adviser who also has buy-side relationships with the type of private equity fund or strategic partner likely to be the buyer has more reason to keep that counterparty comfortable than one who has no such relationship to manage.
We are not suggesting every mixed-model adviser behaves badly. Most do not. But the structure of sell-side-only advisory removes the question entirely, which is why we consider it the right model for founders weighing a partial sale against a full exit.
Conflict of interest policy
- We act exclusively for selling shareholders on every transaction.
- We do not accept fees, commissions or retainers from buyers, investors, funds or partners.
- We decline mandates where a credible conflict cannot be cleanly managed.
- Buyer relationships are treated as counterparty contacts, not clients.
- All founder discussions are treated in strict confidence.
Where a genuine conflict does arise, for example if two founders in the same narrow sector approach us within a short period, we assess it openly and decline the later mandate if a clean separation cannot be maintained. This is a small commercial cost we accept in exchange for keeping the sell-side-only position credible rather than nominal.
What this means for buyer trust in your process
A sell-side-only position also affects how buyers engage with a process, generally to the founder's benefit. Acquirers who deal repeatedly with sell-side-only advisers know that the adviser has no separate agenda and no competing relationship to protect, which tends to produce more straightforward, better-documented processes. Buyers value clarity: a well-prepared information memorandum, a clean data room, and an adviser who responds to due diligence questions promptly and without ambiguity about who they represent.
That clarity supports avoiding common pitfalls in M&A such as process delay, mismatched expectations at heads of terms stage, or disputes that surface only during legal completion.

FAQ
Do you ever introduce buyers to other businesses?
No. We do not maintain buy-side mandates and we do not earn introducer fees from acquirers, private equity funds or strategic partners. Buyer relationships exist only as counterparties inside live sell-side processes we run for founders. This matters because a firm that also works for buyers has a commercial incentive to keep certain acquirers happy across multiple deals, which can quietly influence how hard your price and terms are pushed. Because we only ever act for the seller, there is no relationship to protect on the other side of the table, and no reason to soften a negotiating position to preserve a future introduction.
Can a buyer, investor or private equity fund engage you?
No. Buyers, private equity funds and incoming strategic or growth partners cannot retain Mergers under any circumstance. If you are an acquirer interested in a live sell-side process, you would need to respond through the adviser representing the seller, on the seller's terms. This is a deliberate structural choice rather than a marketing line. It means every fee we earn comes from the founder we are representing, and our only economic interest is in achieving the best outcome for that founder, whether that is a full exit, a majority stake sale, or a minority stake sale where they stay involved.
What happens if a buyer approaches us directly, outside a formal process?
Inbound buyer interest is welcomed, evaluated and folded into the founder's process rather than treated as a separate relationship. Founders are approached directly by trade buyers and private equity firms more often than many realise, sometimes with an attractive-sounding early offer designed to secure exclusivity before the founder has tested the wider market. We assess any direct approach on its merits, but we always advise founders to understand what competitive tension could achieve before agreeing exclusivity. The buyer becomes a counterparty inside a properly run process, not a client, and the founder remains the only party we represent.
How is sell-side-only different from a typical UK corporate finance boutique?
Many UK corporate finance firms operate a mixed model, acting for buyers on some mandates and sellers on others, sometimes in the same sector within months of each other. That is a legitimate business model, but it creates a structural question worth asking any adviser: who else do they act for, and could that relationship shape how your deal is run? A sell-side-only firm has a simpler answer, because there is no buy-side book to manage, no acquirer relationship to protect, and no pipeline of future buy-side fees that could sit in tension with getting you the strongest possible terms.
Does acting sell-side only mean you see fewer buyers?
No, if anything the opposite is usually true. Because we hold no buy-side mandates, we are free to approach the full universe of relevant trade buyers, private equity firms and strategic partners for each mandate, rather than steering process flow towards existing buy-side clients. Buyer research is built around your business and your objectives on each engagement, covering sector consolidators, adjacent-market strategics, international entrants and financial investors as appropriate. The absence of a buy-side book removes any incentive to narrow the list, which supports genuine competitive tension when it comes to negotiating heads of terms.
Is sell-side-only advice more expensive?
Not inherently. Fee structures for UK SME sell-side advisory are typically a mix of a retainer and a success fee calculated on transaction value, and this is broadly consistent whether a firm is sell-side only or operates a mixed model. The commercial argument for sell-side-only positioning is about alignment and outcome, not price. A founder should weigh adviser cost against the quality of buyer targeting, the strength of the negotiating position secured, and how well governance and protections are documented in the shareholders' agreement, rather than assuming a mixed-model firm is automatically cheaper or better resourced.
Where can I read more about how the process actually works?
The clearest starting points are our guide to the sell-side process itself, which walks through preparation, buyer targeting, negotiation and completion, and our founders' FAQ, which answers common questions about timelines, confidentiality and fees. If you are specifically weighing a partial sale against a full exit, our business sale options comparison sets out the practical differences in plain terms. Every one of these resources is written for founders and owner-managers, not for buyers or investors, which is consistent with how we operate as a firm.
