Redefining Mortgages with an Innovative New Lender
How Mohara partnered with Perenna to build a secure, consumer-friendly mortgage portal that helps applicants get a decision in principle faster, easier, and with full regulatory confidence.

Client Background
Perenna is a UK-based fintech reimagining home ownership with 30-year fixed-rate mortgages, a product designed to give customers long-term stability in an uncertain market. As a challenger bank entering a highly regulated sector, they needed to create a seamless, secure, and trustworthy digital journey for prospective borrowers.
The Challenge
Applying for a mortgage is often one of the most stressful consumer experiences. Affordability checks, product comparisons, and credit assessments can overwhelm applicants and delay approvals. Perenna's ambition was to streamline this journey by enabling applicants to secure a Decision in Principle (DIP) online, requiring multiple system integrations, strict compliance handling, and a user experience intuitive enough to inspire trust from day one.
The Solution
Affordability Calculator
adapted from Perenna's existing intermediary tool and embedded directly into the consumer application flow.
Product Selection
including APRC calculations to ensure full transparency for applicants.
Save and Return Portal
secure account creation allowing users to pause and continue applications.
Decision in Principle
full DIP capability, combining WPS affordability models with Experian soft-search credit checks.
Broker Integration
a call-to-action connecting applicants with brokers for a full mortgage application.
Results
A fully functioning Decision in Principle journey completable entirely online
Secure integration with Experian and WPS systems, ensuring accuracy and compliance
Clear, transparent presentation of mortgage products and APRC information
A scalable platform architecture capable of supporting future expansion
Why Mohara
Perenna needed more than an agency, they needed a partner able to navigate regulation, scalability, and user experience simultaneously. Mohara worked closely with their leadership and technical teams to deliver against tight deadlines while ensuring the platform met both consumer expectations and regulatory standards. Startup agility. Enterprise-grade rigour.
