HML said it has kept the number of loans in arrears that result in a possession lower than its peers, and added that it achieves above average proceeds from sale after possession. The servicer also said the performance of loans where HML has negotiated an arrangement to pay is better than its peers.
HML's chief commercial and finance officer, Neil Warman, said: "It's fantastic the transformation HML has gone through since 2008 has been recognised by an unprecedented double upgrade from an independent ratings agency.
"At HML we know the investment we have made in our people, technology and management information is right for our clients and us, this is an upgrade for the whole team and everyone should be proud of the achievement.
"We are very aware of our capabilities in this area and those of other rated servicers and we will continue investing in the quality of our service to ensure another positive review next year."
Overall Fitch indicated that performance was positive compared to last year.
