Nucleus platform
​​​​​​​tax year end hub

The new Nucleus platform - a new era for you and your clients

Welcome to our new Nucleus platform tax year end page, designed to make tax year end as straight-forward as possible. We remain committed to supporting advisers and the platform is built on market leading technology, based on your feedback and with your needs in mind.

If you have clients with products that didn't upgrade in February 2026, you can still access our James Hay tax year end hub.

With our new platform it's easier for clients to consolidate their investments in one place. Some key benefits of the new platform:

  • You no longer need to hold a pension product to open another product, so clients can now transfer in any existing ISA products or open a new ISA to make the most of this year’s allowances.
  • We now offer a wider range of products including a Flexible ISA, Junior SIPP and Junior ISA. A wider range of products to cater for your clients’ needs.
  • New and existing ISAs are now flexible, meaning funds can be withdrawn and replaced within the same tax year without it affecting subscriptions.
  • By consolidating assets clients will only need to pay one platform charge. Additionally, they’ll benefit from a reduced platform fee due to our tiered charging structure (find out our costs and charges).

We hope you find these resources easy to use but if you have any queries, please contact your Business Development Manager.
