Who Holds the Pen? Underwriting Broker Access in UK MGA Transactions
In a UK MGA transaction, the binder is usually the easy part to document. Capacity agreements, delegated authority limits and underwriting guidelines can be reviewed, scheduled and warrantied. Distribution is harder. A managing general agent can hold the pen on risk selection while a small number of brokers hold the pen on demand. When capacity moves, or when a transaction changes ownership, the question is not simply whether the broker list transfers. It is whether the brokers will continue to recommend the product, use the delegated authority and place the same quality of business through the new arrangement.
That distinction matters in 2026 because UK MGA valuations still tend to lean on renewal rights, commission income and historical retention. Each of those measures describes what has happened. None of them proves that distribution access will survive a change of control, a capacity transition or the departure of the individual who has maintained the broker relationship. The book may look portable in a data room. In practice, it may be personal.
A list of contacts is not a distribution right
Broker access is often evidenced by a schedule of appointed representatives, a spreadsheet of producing brokers and a history of premium by source. Those artefacts are useful, but they do not answer the underwriting question. Distribution access is the willingness of a broker to recommend, quote and bind through a particular MGA when alternatives are available. It is influenced by service, remuneration, product fit, claims handling and personal trust. It is rarely owned outright by the MGA unless the paperwork says so.
A practical underwriting review should therefore separate three things: the legal right to receive business, the commercial evidence that business will continue, and the operational ability to transfer the relationship. Confusing them is how buyers end up paying for a book that walks out of the door with two or three people.
Five tests for broker access
1. Contractual foundation. Start with the broker agreements, not the management presentation. Are they with the MGA, the capacity provider or a third-party intermediary? Do they contain change-of-control clauses, non-solicitation provisions or notice periods? Does the capacity agreement require broker consent on novation? Who owns the customer data, renewal dates and quote history? If the answers are split across entities, the distribution right may be weaker than the revenue history suggests.
2. Concentration and substitutability. Measure broker concentration by premium, policy count and commission, not just by headline revenue. A top-three broker share above 40 per cent deserves explanation. A single broker above 25 per cent should be treated as a named exposure. The analysis should also test whether the broker could move the account to another MGA without disrupting the client. If the product is commoditised and the broker has several capacity options, access is fragile. If the MGA provides specialist underwriting, claims authority or bespoke wordings, the relationship may be stickier.
3. Evidence of tenure and behaviour. Retention statistics are more useful when they are broken down by broker and cohort. Look at quote-to-bind ratios, renewal retention, average premium movement and loss ratios by source. A broker that has consistently placed good business through the MGA is more likely to follow the team than a broker that has used the MGA opportunistically. Service metrics matter too. Complaints, turnaround times and claims satisfaction are leading indicators of whether a broker will stay after a transition.
4. Portability of the operating model. Ask who controls the broker portal, the CRM record, the renewal diary and the underwriting correspondence. If the MGA relies on a third-party administrator or a network to hold those assets, the distribution relationship may be intermediated twice. A transition plan should identify which data can be transferred, which consents are required and how quickly brokers can be re-papered. The ability to move a binder in 30 days is not the same as the ability to move a broker relationship in 30 days.
5. Economic alignment. Commission is only one lever. Profit share, service fees, overriders and volume-based incentives all influence broker behaviour. Underwriters should test whether the remuneration structure is portable and whether it remains competitive after the transaction. A broker may stay for a year under a transitional arrangement and then move if the new owner reduces service or changes the commission model. The deal model should include a realistic view of broker economics, not just a retention assumption.
Pricing the exposure rather than assuming it away
Once the tests are complete, the underwriting response should be explicit. Where distribution access is weakly documented, a valuation haircut is appropriate. Where concentration is high, conditions can be attached: a broker retention covenant, a key-person dependency review, staged earn-out payments or a monitoring trigger if a named broker reduces placement volumes. Where data ownership is unclear, an escrow or transition services agreement may be more valuable than another warranty.
The aim is not to eliminate the risk. Broker relationships are personal by nature, and a UK MGA that claims otherwise is probably overselling its controls. The aim is to price the gap between the legal entity and the commercial reality. A book that follows the binder is an asset. A book that follows the person is a contingent liability until proven otherwise.
For UK MGA deals in 2026, the underwriting question is straightforward: if the capacity agreement changed tomorrow, which brokers would still take the call? The answer should be evidenced, not assumed.
