The Association of British Insurers has expelled a further five intermediaries for failing to comply with its Code of Practice.
This brings the total number expelled to 159 since the code was enforced, although the bulk of these were for failing to submit forms needed for monitoring rather than breaches to the code itself.
Ray Stibbard, head of monitoring, said the five expulsions were small to medium-sized personal lines intermediaries.
"These firms have made specific breaches of the code and as a result have had their agencies cancelled by all members of the ABI," said Stibbard.
The non-compliance was uncovered in the six-month period up to September 30, when Stibbard's team inspected 796 firms, ranging from sole trading personal lines intermediaries to large commercial and private medical insurance intermediaries.
The most common breach of the ABI code is non-disclosure of material facts and inaccuracies in the policy forms.
Intermediaries were also found to have failed to disclose their charges, and withheld policyholder documents such as renewal notices or certificates of insurance.
