Zurich is demanding that all personal lines brokers reveal details of referall fee income involving Zurich customers.

Zurich is taking it so seriously it is writing the demand into the Terms Of Business Arrangement (TOBA).

The Swiss-based insurer has taken strong action to improve its motor book, last year raising rates by 20%.

Zurich revealed last week that it was making a return to the aggregators after a seventh month absence.

Endsleigh will carry out sales, servicing and premium collections for Zurich’s aggregator business.

AXA has so far taken the boldest step by banning referral fees. Prime Minister David Cameron last week said he was ‘sympathetic’ towards a ban.

Analysts have speculated that a referral fee ban could hurt Admiral’s profits, which last week suffered its lowest share price price point of the year.
