The Association of Run-Off Companies (ARC) this week accused the insurance establishment of shunning the run-off sector.
The association said established insurance institutions like the CII and the ABI were refusing to acknowledge the role run-off plays in the "lifecycle of insurance".
Peter Abbott, vice chairman of ARC, told Insurance Times: "Over 25% of the reserves in the London market and some 2,500 people are involved in run-off, but we are still treated with indifference.
"The live market can learn a lot from the sector but they choose to ignore us. It is very frustrating."
ARC is understood to have contacted the ABI to request regular meetings between the two bodies, but has so far had no response.
The CII was also accused of failing to acknowledge the role of run-off by refusing to offer specific modules and courses on the skills required for successful run-off.
A spokesman for the ABI said: "If any sector within the market feels overlooked then that is something we would want to address.
"Our first priority is always to our members."
