CROSSFLATTS-based Computershare has maintained its status as the best-rated UK third-party mortgage servicer.
The news follows publication of a report on its operations by global agency Fitch.
Computershare Loan Services currently administers about £100 billion of assets globally.
The firm employs around 1,300 people at Crossflatts and at a second site in Skipton.
Chief executive officer, Andrew Jones, said: "These ratings demonstrate the consistent level of excellence everyone at Computershare Loan Services is able provide to our clients.
"We have first-class systems at our disposal and a great range of talent throughout our organisation.
"I'm very proud that we have again proven ourselves to be the best-rated at what we do."
In its report, Fitch praises Computershare for its "good" risk management and "thorough and comprehensive" internal audit reports, and a "robust oversight" of third-party suppliers.
Tribute is also paid to the industry experience of senior managers, and the timescales for handling customer calls and correspondence.
