Recognised for Outstanding Claims and Underwriting Services

We are one of only three London Market insurers to have been awarded the Service Quality Marque by independent research firm Gracechurch, which reflect exceptional service levels, for both Underwriting and Claims in 2025.

Our leading Claims team has now been awarded the Service Quality Marque for nine consecutive years and topped the rankings for both expertise and relationships in the latest survey. 

 



 

In Underwriting,  brokers consistently cite speed and availability as TMK's standout strengths. TMK's underwriters are also recognised for being easy to deal with, further cementing our reputation for delivering exceptional service and fostering strong broker relationships.

Like art and science, IQ and EQ, tradition and innovation, our formula is how we balance seemingly conflicting ideas – and is the catalyst for our success.
