Gen H, April Mortgages, West One and Bluestone Mortgages are now live on the affordability calculator platform designed to support brokers with affordability assessments.

Each of these lenders has worked closely with the Knowledge Bank team to ensure their affordability models are aligned and accessible to brokers using the system.

Rather than asking brokers to interpret multiple affordability calculators individually, AffCalc streamlines the process by combining affordability with criteria logic.

Marie Grundy, managing director of mortgages at West One, commented: “West One are delighted to be partnering with Knowledge Bank with the launch of AffCalc, allowing brokers to access instant affordability decisioning for residential mortgage customers while instantaneously running real time criteria checks in the background.

“This is such a valuable tool for intermediaries when you consider not only the time saving efficiencies, but also the unique combination of simultaneous affordability and criteria verification which is another example of the innovation that the team at Knowledge Bank continue to deliver.”

Sarah Palmer, sales and distribution director at GenH, added: "We’re really excited to be joining AffCalc as having a clear picture of affordability early on in the journey is a critical part of providing the high-quality advice that buyers depend on.

“Brokers perform a critical service as they source the best possible lender and product for each and every buyer — and we’re looking forward to working with Knowledge Bank in 2026 and beyond."

Commenting on the latest lenders joining AffCalc, Shane Chawatama, sales director at Knowledge Bank (pictured above), said: “It’s been fantastic to see just how keen lenders have been to be part of AffCalc.

“The willingness of lender tech teams to work closely with us has been a huge factor in getting these lenders live and ensuring brokers have accurate, trusted access to their affordability models.

“AffCalc will play a major role in our plans for 2026 and beyond as we continue to support both brokers and lenders with better, more informed decision-making.”
