Jardine Lloyd Thompson (JLT) has become the latest broker to join the peer-to-peer initiative being led by the so-called G6 group of Lloyd's managing agents.
It joins brokers Aon, Benfield, Marsh and Willis in working with the group.
JLT said it aimed to engage with the group's initiative piloting an XML placing message via email.
Richard Borgonon, chairman of JLT's business reform group, said: "It is indisputable that in the future the electronic transfer of information between broker and markets is going to be an essential pre-requisite for trading in the London market, in the same way as in Bermuda and Europe."
G6 recently agreed to a new process using Acord data standards, which will allow the electronic transfer of risk-related data and documents between group members and the five brokers in the Lloyd's market on a peer-to-peer basis.
Sue Langley, G6 chairman and Hiscox chief operating officer, said: "The more people we work with means that the standards will become adopted across the market which is exactly what we need if we are to reduce costs and improve efficiency."
