Aon Lifts Committed Lloyd's Capacity to 35%
Insurers placing large or complex risks through Aon gain committed capacity for a larger share of each placement from 2027.
Updated on Nov. 4, 2026 in Corporate Finance
Aon has renewed its Aon Client Treaty (ACT) follow facility for 2027 and raised 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, which matters for insurers and brokers placing large or complex risks.
Why it matters
Growing client demand for committed capacity drove the expansion, giving insurers placing large or complex individual risks access to committed capacity for a larger share of each placement, subject to eligibility criteria. For operators in insurance distribution and corporate risk buying, committed capacity reduces the uncertainty of whether a complex placement will be fully covered.
The disclosed capacity figures are a shift from 28.5% to 35% of pre-secured Lloyd's co-insurance, and the facility has placed more than $5 billion in gross written premium since 2016. The 1.5% ACT Client Dividend applies to the 35% share, where permitted by local law and regulation and subject to eligibility.
The players
Aon
Aon is a global professional services firm offering insurance broking and risk management, and it operates the Global Broking Centre through which eligible business is placed.
QBE
QBE is an international insurer that leads the Aon Client Treaty facility.
Reinsurance Solutions
Reinsurance Solutions is the Aon unit that places facultative reinsurance eligible for the expanded capacity.
The details
The Aon Client Treaty is a facility led by QBE and backed by Lloyd's syndicates, under which clients gain access to pre-secured co-insurance capacity on eligible placements. Clients can access the 35% pre-secured capacity on eligible business placed through the Global Broking Centre and on facultative reinsurance placed by Reinsurance Solutions. ACT has supported facultative reinsurance since late 2025, and the expansion extends committed capacity to that line.

1 January 2027: The 35% pre-secured capacity takes effect.
Market Landscape
The expansion extends a facility launched in 2016 that has placed more than $5 billion in gross written premium, now reaching facultative reinsurance placed since late 2025. It positions committed Lloyd's capacity as a broker-led offer for clients placing large or complex individual risks.
Risk managers and insurance buyers placing large or complex individual risks should review whether the 35% pre-secured capacity applies to their placements from 1 January 2027. Operators should confirm eligibility criteria and the local-law treatment of the 1.5% ACT Client Dividend with their broker or qualified counsel.
The takeaway
Committed capacity is becoming a broker-supplied tool for insurers placing complex risks, so procurement and risk teams should add it to their renewal evaluations. Track eligibility criteria and any published uptake figures as the 2027 facility takes effect.
