A spokesperson from Guardian told Mortgage Solutions that it has pledged to grow the £700m protection market.
Launched in Q3 2018, the protection challenger was established with £180m of investment provided by PSG and Leadenhall Capital Partners.
Guardian has also strategic partnerships in place with Iress, iPipeline and Synaptic portals.
Mike Devaney, head of strategic partnerships at Guardian, said that its team is delighted to partner with HLP, working closely with the management team to support advisers to make sure every customer has their mortgage fully protected.
He added: “From today our sales team will be contacting advisers all around the country, and in July we’ll be joining the HLP protection workshops to share details of our proposition.”
Shaun Almond, managing director of HLP, said: “Guardian is a valuable addition to the panel because its high quality life and critical illness products reflect the advice that our members give their customers.
“The comprehensive cover and simple definitions allow our members to explain the true value of protection to their customers in terms that are easy to understand. The cover upgrade promise also gives confidence that Guardian’s critical illness definitions stay relevant and don’t let customers down at the point at which they need to claim.”
