Accord had an existing relationship with Connells through Chelsea's intermediary lending arm Chelsea Intermediary Services, which ceased operating in October last year as part of the integration of Chelsea’s services with its merger partner, the Yorkshire - parent of Accord.
Connells was one of three key lending partners to work with the Chelsea before the merger.
Connells Group was founded in 1936 and owns nearly 470 branches nationwide, making it the second largest UK estate agency group.
As well as residential property sales and lettings, the Group has a comprehensive range of B2C and B2B services including a comprehensive mortgage service.
Karen Faulkner, mortgage services development manager of Connells, said: “We are delighted to build on our longstanding relationship with Chelsea by having Accord Mortgages join our Restricted Lender Panel and at a key point as we expand our sales force by a further 100 mortgage consultants.
"We look forward to working alongside the Accord team to ensure we provide our customers with the widest range of competitive mortgage products.”
Chris Maggs, divisional manager south of Accord Mortgages, said: “At Accord we focus on developing key intermediary lending partnerships and we’re delighted to be working with Connells.
"The Connells Group offers quality controlled mortgage distribution alongside its estate agency and new homes services and is well placed in the intermediary market to drive new business and ensure people find the mortgage deal they need to secure the property they want.”
