Triodos

For Triodos Bank, this project was about more than digitalisation. The ambition was to make sustainability an integral part of the digital mortgage journey, and to give customers more insight and control. That brought a complex challenge. How do you let customers explore mortgage and sustainability scenarios on their own, while every outcome matches the adviser’s calculations? And how do you make complex mortgage logic accessible and clear? Together with Triodos, Yellowtail Conclusion developed a digital customer journey that brings mortgage calculations, sustainability and personal advice together.

Making sustainability part of every step

Triodos Bank wanted sustainability to have a permanent place in the mortgage process. Customers needed insight into their sustainability options, the financial impact of those options and the choices that suit their situation, right from the moment they start exploring.

At the same time, the bank wanted to give customers more control. Instead of waiting for an advice meeting to explore their options, customers compare scenarios themselves and make better-prepared choices. That placed high demands on the technology. Every calculation had to match the adviser’s outcomes exactly, including for complex mortgage structures and Triodos’s specific sustainability schemes.

One environment for mortgage, sustainability and advice

Together with Triodos, Yellowtail designed and delivered an integrated solution that brings research, mortgage calculation, sustainability and customer contact together. The solution combines a proven mortgage calculation engine with custom work for Triodos’s products, mortgage rules and sustainability options.

Within one environment, customers calculate mortgage scenarios, compare their financial options, see the impact of sustainability measures, explore improvements to their home’s energy label (the Dutch equivalent of an EPC rating) and contact an adviser directly, either by booking an appointment or by video call from the portal. Altum AI supplies the underlying sustainability data, such as energy label and property data. The outcomes always match what the adviser sees, however complex the scenario.
