The London Market Group’s Data Council has opened the last major extension of the Core Data Record programme. The consultation, launched on 5 June 2026, brings delegated authority business within a unified data standard for the first time.
The consultation runs until 19 June 2026. Market members can access materials via the LIMOSS website. Briefing sessions are organised through the International Underwriting Association (IUA), London & International Insurance Brokers’ Association (LIIBA), and Lloyd’s Market Association (LMA).
The proposed data set aligns with the Computable Binding Authority Agreement (CBAA). It establishes standardised fields to support the creation, management and exchange of core data records across the London Market.
The DA CDR is the third major extension of the standard. It follows the open market CDR released in 2023 and a claims CDR consultation that closed earlier this year. Together, these three extensions now cover the full lifecycle of a London Market risk.
The treaty reinsurance CDR was published as v3.3 in May 2026, following input from 68 organisations. It extended the standard to cover both proportional and non-proportional business.
At that stage, Kirstin Duffield, chair of the CDR working groups on behalf of the LMA, confirmed that DA CDR development was already under way. She said it would align closely with the CBAA.
Joe Brace (pictured above), Data Council member and operations director of the LMA, said the extension closes a long-standing gap.
“The extension of the CDR into delegated authority is the final piece of the CDR jigsaw for the market,” he said. “When implemented it will move us towards a space where all London Market businesses can work on a clear overall CDR framework.” He added that the change would be a significant step forward for both insurers and brokers.
The consultation arrives against a firm timeline. In December 2025, Brace set out the goal of a common data language across risk, claims, and delegated authority by end of 2026. The DA CDR forms a sub-set of the full CBAA data model. Its development runs in parallel with the CBAA’s own progress.
Brace urged all DA teams to engage before the deadline. “I encourage all delegated authority teams in the market to get involved and give feedback to help finalise this extension to the CDR,” he said.
Firms wishing to participate should contact their relevant market association. Questions can be directed to the LIMOSS Service Desk.
