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

The new Nucleus Platform - a new era for you and your clients​​​​​​​

We’re excited to introduce 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 the recent upgrade in early February, you can still visit our James Hay tax year end hub.

This new platform is a step change in how you service your clients. With joined-up processes, auto-population of client data and smart search functions, which will save you time, plus a variety of drawdown options and a wider range of investment choices, providing you with greater control and flexibility when managing your client’s investments - helping you deliver their best financial future.

Our new platform brochure has more information.

Although the new platform is designed to be intuitive, we appreciate that using new technology for the first time can sometimes be daunting. So, this page will focus on what you need to know specifically for tax year end. For all other processes and questions, you’ll find a wide range of training guides and brochures on our support pages.

And remember, with our new platform, you no longer need to hold a pension to open an ISA or other product, making it easier than ever for your clients to consolidate their investments in one place. Some things to note about 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  • New and existing ISAs are now flexible, meaning funds can be withdrawn and replaced within the same tax year without it affecting subscriptions.
  • It’s a great opportunity for clients to consolidate their assets as it could mean they only need to pay one platform charge and not pay for multiple providers. 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.

Topping up and placing new business at tax year end

One of the many benefits of our new platform is you no longer need to hold a pension to open a new product. So, as well as topping up in the usual way to use allowances before tax year end, now’s the time to consolidate clients' investments through Bed and ISA or opening an ISA or JISA.
