Aon Expands Client Treaty Capacity to 35%

Aon has renewed its Aon Client Treaty follow facility for 2027, increasing pre-secured Lloyd's co-insurance capacity from 28.5% to 35% effective 1 January 2027. The expanded capacity applies to eligible business placed through Aon's Global Broking Centre and to facultative reinsurance placed by Reinsurance Solutions.

Why it matters

The expansion reflects growing client demand for committed capacity, giving insurers placing large or complex individual risks access to a larger portion of each placement, subject to eligibility criteria. It also extends the facility's reach to facultative reinsurance, which ACT has supported since late 2025.

The Client Dividend of 1.5% applies to the 35% share where permitted by local law and regulation, against a prior pre-secured capacity of 28.5%. Eligibility criteria governing access to the expanded share were not detailed in the source.

The players

QBE

Aon

Aon is a global professional services firm offering broking, risk, and reinsurance solutions to clients worldwide.

Lloyd's

The details

QBE leads the Aon Client Treaty facility, which is backed by Lloyd's syndicates and launched in 2016. Clients will be able to access the 35% pre-secured capacity on eligible business placed through Aon's Global Broking Centre and on facultative reinsurance placed by Reinsurance Solutions.

Timeline

  1. 2016: The Aon Client Treaty facility launched.

  2. Late 2025: ACT began supporting facultative reinsurance.

  3. 1 January 2027: The 35% pre-secured capacity takes effect.

Market Landscape

The expansion builds on the Lloyd's syndicate capacity model, under which backing syndicates provide co-insurance capacity to placements brokered through intermediaries like Aon. Raising the pre-secured share from 28.5% to 35% signals a larger commitment of that capacity to client programs.

Insurers placing large or complex individual risks may access committed capacity for a larger share of each placement from 1 January 2027, subject to eligibility criteria. Clients should confirm eligibility with their broker, as the source does not specify how the 1.5% Client Dividend applies in each jurisdiction.

The takeaway

Expanded committed capacity can improve placement certainty for large risks, but clients should verify eligibility and local dividend rules before relying on the higher share.

What happens next

The expanded 35% pre-secured capacity takes effect on 1 January 2027.
