Pepper sales director Paul Adams says: “We see that an increasing number of customers require a more considered approach to mortgage lending, and brokers play a vital role in helping them find the right solution.
“With the ability to consider clients with recent credit events, as well as flexibility around self-employment and variable income, our criteria are designed to look at the full story of each client.
“By lowering prices across our entire range, we are giving brokers more options to support clients beyond the high street and help more people move forward with their home ownership plans.”
