MediQuote, the comparative PMI portal managed by Sirius have announced that Norwich Union Healthcare's rates have been made available on their system.
The move follows the results of a MediQuote survey, which showed that Norwich Union was its user's most popular insurer.
Since its launch last year, MediQuote has attracted over 1300 users.
The portal has also been extended to IFA networks such as Burns Anderson, Countrywide and DBS.
Managing Director of Sirius' Insurance Division Mike Dodd said: "This is an important development for MediQuote. Norwich Union's addition as a sponsoring insurer will further enhance the appeal of the system.
"Intermediaries will now have easier and quicker access to Norwich Union's information, all available on one system."
Head of Business Development Carolyn Derrington said: "The use of technology in our sector to gather information is set to grow.
"Having our products easily more fully available via MediQuote should make access to Norwich Union's information even simpler, and we are pleased to be working with MediQuote in this development."
