Aventum-owned MGA secures new capacity as it continues to grow portfolio

Aventum Group-owned MGA Rokstone has obtained new capacity for international facultative property, power and onshore energy.

The MGA said it had secured a new binder agreement with Lloyd’s Somers Syndicates 3705 and 5423 and will use the new capacity to offer coverage tailored to the evolving needs of clients.

The deal expands Rokstone’s portfolio of A-rated markets, including Munich Re, Allianz, Arch Re Bermuda and Aviva.

“The latest partnership with Somers adds a fresh and dynamic provider to the panel for a diverse range of reinsurance solutions,” the MGA said.

Henry Hogarth, senior property D&F underwriter at Rokstone, added: “We’re thrilled to partner with Somers as we continue to grow and diversify our portfolio and at a time of increasing demand for specialised reinsurance solutions across these lines globally.

“The agreement further strengthens Rokstone’s ability to offer clients comprehensive, world-class coverage across international facultative property, power and onshore energy.

“This deal not only expands our offerings, but also reinforces our position as a key player in the global reinsurance sector.”

Lloyd’s expansion

The new capacity comes as Rokstone hinted at expanding its presence at Lloyd’s.

In December 2024, eight months after establishing its first box, the MGA acquired its second box at Lloyd’s to enhance face-to-face access between brokers and its underwriters.

Rokstone now operates box 398a in addition to its existing box 398 – both on gallery three – with the intention of providing expanded coverage in financial lines and casualty.

Ian Anson, global chief executive at Rokstone, explained that the move came after the initial box quickly became a hub of activity, prompting the need for additional space.

“We took our first box in April and had each division on a rota to ensure access,” he said.

“But the demand was overwhelming and it became clear we needed more time at Lloyd’s to meet our objectives.”

He added: “It’s likely that we’ll outgrow our current space in the near future. Watch this space.”
