Rickard is leaving the company to pursue other opportunities having completed the first stage of its refinancing.
Mangold joined Taylor Wimpey in April 2009 as group financial controller.
Taylor Wimpey has been in negotiations with its bank for most of the year about its debt facilities and has now agreed a revised £950m credit facility, conditional on obtaining £350m of debt capital market funding in the public or private debt capital markets.
The second stage of refinancing, which relates to the group's Private Placement Notes and Eurobonds, is expected to be completed by the end of the first quarter of 2011.
