OakNorth Launches Junior Cash ISA with Competitive 3.5% Rate

How OakNorth Plans to Engage Young Savers

OakNorth Bank has introduced its first Junior Cash Individual Savings Account, offering a 3.5% annual equivalent rate for children under 18. The product launched in October 2026 and is available through the bank’s digital platform, with a minimum opening balance of just £1. This marks a significant expansion of OakNorth’s offerings into the youth savings market after more than a decade of focusing primarily on business and adult retail banking.

The Junior Cash ISA allows parents or guardians to save on behalf of a child, with funds accessible only when the account holder turns 18. Transfers from existing Junior ISAs held at other providers are permitted without impacting the annual subscription limit, which remains set at £9,000 for the 2026/27 tax year. OakNorth emphasizes that the account is protected by the Financial Services Compensation Scheme up to £85,000 per eligible individual.

To support the launch, OakNorth has partnered with Bubble, a childcare coordination app widely used by families across the UK. The collaboration aims to integrate financial education tools and savings tracking features into the Bubble platform, helping parents visualize long-term growth for their children’s savings. OakNorth stated that the partnership reflects its commitment to making saving accessible and engaging for younger audiences through familiar digital touchpoints.

What Benefits Does This Offer Compared to Traditional Options?

Unlike many standard children’s savings accounts that offer tiered or conditional interest, OakNorth’s Junior Cash ISA provides a fixed 3.5% AER on the full balance, with no minimum monthly deposit required. The rate is variable but currently stands above the average for easy-access children’s savings products in the market. Industry analysts note that the combination of a competitive rate, low entry barrier, and ISA tax efficiency positions the product as a strong contender in a increasingly crowded junior savings space.

The introduction of this product signals OakNorth’s strategic shift toward diversifying its retail footprint beyond its traditional focus on SME lending and business accounts. By entering the Junior ISA market, the bank aims to build early-stage customer relationships while addressing a growing parental demand for tax-efficient, high-yield savings vehicles for children.
