The new arrangement means that the 387 HoC Appointed Representatives now have access to MBS residential, buy-to-let and commercial products.
Advisers can source both Manchester Building Society and Whiteaway Laidlaw Bank products, benefiting from their individual, non credit-scoring approach to writing business.
Ian Richardson, executive director of Manchester Building Society said: "We're delighted to be added and are confident that HoC's professional advisers will see real value by gaining access to our products. We are able to talk cogently about propositions and offer improved certainty that funding will be available to their clients, so that positive outcomes can more reasonably be expected. Cases can be discussed directly with our highly trained and experienced underwriting team, who conduct a personalised assessment of each application."
