After 100 days of Financial Conduct Authority regulation, Martin Wheatley believes the FCA as a "very different animal" to the FSA.
Mr Wheatley, who is FCA chief executive, will make the comment at the Association of British Insurers biennial conference today.
He will tell delegates: "One of the questions I was most frequently asked 101 days ago was: 'Is the FCA going to be genuinely different from the FSA?'. We understand why people reserved judgement - the FSA needed to change.
"100 days later I think we are taking steps in the right direction. The FCA is in many areas a very different animal from the FSA.
"We're not just asking: Is this product compliant? Does it tick every legal box? But actually: is the outcome good? Is the market competitive? And is fair treatment of consumers designed into products and culture?"

Mr Wheatley feels the most significant change for the regulator is the new competition duty. This looks at promoting competition in the markets and its first market study will look at general insurance.  
The FCA was formed on 1 April 2013 as one of two successors for the Financial Services Authority. It deals with conduct supervision of financial firms while the Prudential Regulation Authority handles prudential supervision.
