Andrew Gibson is to become chief executive of Ockham while Ross Dunlop is to become executive chairman.
Gibson was previously group finance director, as well as managing director of Ockham's motor insurance business.
Dunlop was previously non-executive deputy chairman of the company.
Chris Hill and Ian Patrick have been appointed to the board as underwriting director and finance director respectively.
The group also announced today it is to change its name to Highway Insurance Holdings plc to reflect its focus on its core business.
Executive chairman Ross Dunlop commented: "Ockham will in future concentrate on Highway and accordingly will propose to shareholders to change the name of the parent company to Highway Insurance Holdings PLC."
Chief executive Andrew Gibson added: "We are already starting to receive benefit from the company's recent substantial investment in IT. On 1 July we launched 'Highway Choice', a new private car insurance product which consolidates the previous range on a simpler basis.
"It will be priced on the basis of better, more timely information and will enhance our competitive position. We have also been streamlining our operations and our new systems will allow for continuing tight cost control."
The group said that UK motor insurance market conditions remain favourable.
