If you've followed Lloyd's start-up news over the past couple of years, you'll have noticed a pattern. A Bermuda-based re/insurance group announces it's heading to London. It picks up in-principle approval from the Lloyd's Council. And then, buried a paragraph or two down, comes the same name: Asta.

It happened again this month with Cedar Trace Underwriting, the Bermuda-based platform fronted by industry veteran Brian Duperreault. Cedar Trace is heading into the Lloyd's market for the 2027 underwriting year with Asta lined up to run the managing agency side of things. It's a similar script to the one followed by Agile Underwriting Services, and, more strikingly, by Richard Brindle's Fidelis Partnership a founder with three and a half decades in the market, who still chose to outsource the agency function rather than build one from scratch.

So why do groups with money, underwriting talent and, in some cases, decades of Lloyd's experience on the board keep renting rather than building?

You can't underwrite at Lloyd's without one

Nobody gets to write business at Lloyd's without a managing agency sitting behind the syndicate. It's the entity that's authorised by Lloyd's and the Prudential Regulation Authority to run the show including staffing, compliance, reserving, capital modelling, the lot. A capital provider or an underwriting team can bring the money and the risk appetite, but someone still has to hold the licence and run the machinery underneath it.

Building that machinery from a standing start is not a quick job. It means recruiting compliance and actuarial staff who understand Lloyd's specifically, standing up systems that talk to the market's own infrastructure, and going through Lloyd's own approval process for the agency itself, on top of the approval needed for the syndicate. For a new entrant, that's a lot of fixed cost and lead time before a single line of business gets written.

Third-party managing agents exist to remove that step. Asta describes itself as the market's leading firm in that role, saying it has helped launch more than twenty syndicates over the past two decades and currently runs upwards of ten syndicates, several syndicate-in-a-box vehicles and a handful of MGAs. Under its turnkey model, a new entrant can in principle be trading at Lloyd's within roughly three months for a syndicate-in-a-box structure, according to Astra’s own pitch.

Agile: the fast, cheap route in

Agile Underwriting Services is probably the cleanest example of what that route looks like in practice. It secured in-principle approval from Lloyd's for Syndicate 2427 under the syndicate-in-a-box framework, targeting gross written premium of £34.1 million in its first year and projecting growth to £62.1 million by 2026, focused on SME-facing lines including liability, professional indemnity, and travel.

A year on, Agile reported it had used that Asta-run platform to push into new lines, add broker relationships, and convert its original MGA entity in Australia into a full Lloyd's service company, while opening new service companies elsewhere. None of that required Agile to first build a UK-regulated managing agency of its own. The Asta relationship gave it the licence and the back office, leaving the team to concentrate on underwriting and distribution.

Fidelis: proven Lloyd's pedigree, still outsourced

Fidelis is the more interesting case, because it isn't a first-time entrant figuring out how Lloyd's works. Richard Brindle spent years underwriting at Lloyd's syndicates before founding Lancashire in 2005, and his return to the market with Syndicate 3123 in 2024 was framed at the time as exactly that, a comeback. Even with that background, and with Hampden Agencies, the market's largest provider of private capital, alongside him, the syndicate launched with Asta running the agency function rather than a bespoke Fidelis managing agent.

The syndicate went on to start underwriting in July 2024 with an initial target of $180 million of gross written premium for the second half of that year, rising to a $450 million target for 2025. What the Fidelis and Agile examples share, despite sitting at very different ends of the experience spectrum, is that neither felt the need to internalise the agency function before writing a single risk.

Renting now doesn't mean renting forever

None of this means third-party management is where these platforms necessarily end up staying. Asta itself is candid that its turnkey arrangements are often a stepping stone: the model is explicitly built to allow a syndicate to "graduate" into running its own managing agency once it has the scale and track record to justify the investment. Asta business development director Keith Nevett has pushed back on the idea that third-party management is the expensive option, arguing that economies of scale keep costs down, and noting that syndicates which do eventually strike out on their own often come back to Asta for specific services anyway.

Worth bearing in mind for Cedar Trace's own move: a start-up backed largely by existing shareholders and by investors in insurance-linked securities funds tends to prioritise speed to market and lower fixed overhead in the early years, exactly what an Asta-style arrangement is built to deliver. Whether Cedar Trace, Agile or Fidelis eventually build their own Lloyd's agencies comes down to how big and how permanent each platform's London ambitions turn out to be, not a verdict on the third-party model itself.

Why it matters beyond the players involved

The bigger picture is a Lloyd's market that has become noticeably more hospitable to this kind of arrangement. According to Howden Re's most recent syndicate analysis, the market closed 2024 with total capacity up to £56 billion, but the share of that capacity held by the ten largest syndicates actually fell, from 39% to 37%. Growth is increasingly coming from smaller and mid-sized entrants rather than the market's biggest names, and new syndicate start-ups reportedly reached a five-year high.

For brokers and cedants, more syndicates chasing business generally means more negotiating room and a wider set of relationships to draw on when placing programmes. For the Bermuda groups themselves, the Asta route offers something harder to quantify but just as valuable: the chance to test whether London is worth a long-term commitment before betting the balance sheet on building a managing agency to find out.
