The IDI (Inviting Difference In) Broker Portal is Nottingham Building Society’s next-generation broker portal, built to remove friction from the mortgage journey and give brokers faster decisions, greater certainty and more time to focus on their clients.
Powered by MQube’s award-winning Origo technology, IDI represents a step change in how we originate, assess and progress mortgage applications and more importantly, our borrowers’ home ownership journeys. It combines advanced AI-driven processing with a simple, intuitive user experience - delivering decisions in minutes, not weeks.
This isn’t just a fancy new platform. It’s a fundamental shift in how lending should work.
The way people live, work and earn has changed, but mortgage processes haven’t always kept up.
Too many applications still get slowed down by manual checks, unnecessary document requests and rigid workflows. That creates frustration for brokers and uncertainty for borrowers.
As a mutual that is over 175 years old with a strong track record of innovation, we knew there was a better way.
That’s why we partnered with MQube in 2024 to reimagine the mortgage journey from the ground up, combining our customer-first lending approach with cutting-edge technology to build something faster, fairer, and fit for modern borrowing.
The result is IDI: a broker portal designed to take the friction out of lending and unlock better outcomes for brokers and borrowers alike.
IDI is built around speed, simplicity and certainty, without compromising responsible lending. Take a look at the key benefits for brokers.
To show how IDI came to life, and where it’s heading next, we created The Future Lender, a three-part video series filmed in collaboration with MQube, exploring the journey behind the platform...
Find out how our partnership with MQube began in 2024, and how a shared vision for innovation helped take IDI from concept to live platform in just 12 months.
Go behind the scenes on what “building better” really means: from improving broker journeys to creating smarter, simpler ways of working for everyone involved.
Hear how brokers are responding, what success looks like in practice, and how new-school approaches to lending are shaping what comes next.
Residential purchase and remortgage applications are the first propositions live on IDI.
Currently available:
Over time, we’ll continue moving additional products onto the platform, including buy-to-let, foreign national applications and future propositions, as part of our phased rollout. Stay tuned for more!
To use IDI, you’ll need to register for the new portal, even if you’re already registered on our existing broker system, now known as 'classic'.
You’ll then choose which system to log into depending on the type of case you’re submitting.
Before registering, please ensure you hold the appropriate Financial Conduct Authority authorisations to submit mortgage applications.
(Note: application reference numbers on IDI begin with “NBS”).
IDI is more than a portal. It’s our commitment to building a faster, fairer and more inclusive mortgage market, alongside brokers. If you’re ready to experience a simpler, smarter way to place cases with Nottingham Building Society, we’d love to welcome you in.
