Paradigm noted that for member firms who are not active in the large loan space, there is the option of referring the client onto another member firm that is.
Richard Howes, director of mortgages at Paradigm, said the firm had worked closely with Harpenden for some time, with the products coming at a significant discount from Harpenden deals on offer to the wider market.
He continued: “For advisory firms who are not active in this space, but who may be dealing with clients needing larger loans, we offer a quality referral process that will ensure borrowers have access to those firms who do offer this specialist service.
“Those who refer can ensure their clients are in the safest of hands, plus they also receive the referral income, not forgetting the benefits of being able to signpost clients to specialists – a big focus of the Consumer Duty rules.”
Andrew Foster, commercial manager at Harpenden Building Society, pointed out that the mutual specialises in working with clients with complex income streams and non-standard requirements.
