Andrew Jones, chief executive officer of HML, signed the deal with Kensington head of mortgages Keith Street in January.
HML has serviced Kensington’s Mortgage Portfolios since their launch in 1994.
Jones said: “Kensington is a longstanding and valued strategic client of HML and we have made a significant investment in this relationship to which we are fully committed. We are absolutely delighted to extend it for a further five-year period.”
Street added: “HML has been a key supplier to Kensington for a number of years and is an important cog in our operations. It is fantastic news that we will continue to work together to create an even stronger and more collaborative relationship that will allow us to maximise value from the portfolio.”
