JLT has reported new business wins in the second half of 2005 including Delta, Tullett Liberty and Shepherds Building Group, all of whom were won following a selection process.
The company said the majority of new clients have appointed JLT on a full services (actuarial and administration) basis.
JLT said the second half also included a further 12 client appointmets.
Jim Gallagher, sales director, said: "Our new business success demonstrates the benefit of our enhanced sales and marketing activity and the development of our overall proposition within a continually competitive market.
"There is a definite trend within the corporate market to continually seek service enhancements, innovative approaches, while also obtaining value for money.
"A number of our major competitors appear not to be responding to this changing environment, and in particular to their mature DB clients. The market is certainly seeking solutions at a value for money fee level".
