Biba is to push for tough deadlines on renewal quotes in a bid to achieve contract certainty in the regional market.

The trade body wants insurers to expand the 21-day renewal period agreed for liability policies to all risks, extending the deadline to 30 days or greater for complex risks.

Biba head of technical services Peter Staddon said: "This move would require a change of mindset by the insurance industry. The marine market has got to get itself together on this.

"It has standard institute clauses. This requires insures to fight on price and service, for example claims."

The move comes on the back of research conducted by Biba into whetther there is lack of contract certainty in the regions.

The ABI is conducting a similar study.

Staddon said that results from Biba's study so far showed that there was a problem over contract certainty in relation to "bespoke commercial combined policies".

But he said he had found no problems with retail or package policies.

"[In commercial combined policies] the percentage of errors is in double figures - enough to be concerned about. "We want to see 90% perfection," he said.

Staddon said the results were based on an assessment of a million policies from 90 brokers.

The ABI's study had found a similar pattern of errors, he added.

The probe into contract certainty into the regional market is being undertaken by a working party headed by Royal & SunAlliance UK chief executive Duncan Boyle.

Staddon, who sits on the working party, said that draft proposals to address contract certainty would be issued shortly.

An ABI spokesman said that renewal deadlines was "one of the factors" being looked at.

Boyle declined to comment.
