Hutchinson will remain with the Group until April, when Andy Clapham, Investec's head of principal finance, will be taking over in her stead.
David van der Walt, Investec head of capital markets praised her commitment over the 'testing times' of late.
"She has delivered on every level and we are very sorry to see her go, but with the integration now well advanced, we fully understand her decision to take a break," he said, adding, "All at Investec wish her the very best for the future.”
After implementing a full business restructure and repositioning itself in the market, Hutchinson believes that the lender is now in a very strong position.
Hutchinson said: "I am very proud to have been part of Kensington’s evolution over the last four years and its recognition across the mortgage industry as one of the top specialist lenders.
"Looking forward, Kensington is now in a stronger position as part of the Investec Group to chart a successful course through these challenging markets and to explore the new opportunities that will result.”
