James Hay upgrade

The upgrade of James Hay customers to the new Nucleus Platform is now complete.

This information is for James Hay users who upgraded to the new platform in February 2026. It brings together the key information you might still find useful following the upgrade, including FAQs, copies of the client letters we sent, and the important actions and changes to be aware of.

As communicated to you before the upgrade, any instructions sent after the deadline dates provided for James Hay Online will now need to be re-submitted on the new platform. Our support hub provides all the information you need to get started. 


Need help with the new platform? 

Our new support hub offers a go-to resource for you and your clients, with a wealth of information, training, and support materials to help you get the best out of the Nucleus platform. 

Which products are being upgraded?

Read about which James Hay products are being upgraded to the new platform (most of them) and which are not (just a few).



The majority of active James Hay products will have a new home on the Nucleus Platform, and the products included in the upgrade are shown in the table below. We’re also taking the opportunity to simplify our product range.

Customers with our James Hay Wrap and Private Client SIPP products will upgrade to the comprehensive Nucleus Modular iPlan, along with existing Modular iPlan customers. It'll now include access to an offshore bond, alongside the SIPP, ISA and GIA wrappers already provided.

Please note that as well as the Life Company SIPP products, the Modular iPlan will become closed to new customers. You and your clients can continue to do everything you need to (for example, continue to contribute or make additional transfers in) and add further product wrappers as and when required. 

The iSIPP is being upgraded and renamed Nucleus Flexi SIPP. Existing iSIPP customers will move into the upgraded version and continue to have access to investment manager accounts. 

If any of your clients would prefer not to move to our new terms and conditions for any reason, we’re happy to facilitate a transfer.

Our Partnership SIPP, IPS SIPP products and a very small number of other SIPPs, aren’t upgrading at this time. They’ll continue to be accessed using James Hay Online.

Products not being upgraded

A small number of existing James Hay products are not upgrading to the new Nucleus Platform.

These are:

  • Aviva (Friends Life) scheme
  • IPS SIPP
  • IPS (2008) SIPP
  • IPS Pension Builder SIPP
  • IPS Family SIPP
  • Partnership SIPP
  • Phoenix scheme
  • Sarum scheme


Brand new customers will have access to our new multi wrapper platform and Flexi SIPP.

No changes will be made to Nucleus Wrap products at this time although adviser materials will also be rebranded to adopt our new group identity.

A fresh identity and streamlined structure

We have a vibrant new brand. The concept behind it is ‘rewarding relationships’ – two elements coming together to create something better.

And following the recent growth of our group, we’ve made some changes to how our company is structured.

We’ve changed our name to 'Nucleus’ and have a fresh new brand. This transformation is already reflected on our site and will extend to the new platform. In addition, we're consolidating our company structure:

RoleCurrentFuture
Scheme administratorJames Hay Administration CompanyNucleus Financial Services
ISA ManagerJames Hay Wrap Managers
TrusteeJames Hay Pension TrusteesNo change
NomineeJames Hay Wrap Nominee Company Limited
Pension schemeJames Hay Personal Pension Plan











This means that both our terms and conditions and terms of business for the new Nucleus Platform will be under the umbrella of Nucleus Financial Services. However, these legal entity changes have no operational impact on your clients’ Nucleus products.

The James Hay name will live on in our legal structure, SIPP bank accounts and the Trustee for the Nucleus SIPP, so you’ll still see it from time to time.

Platform status

Our aim has always been to upgrade you and your clients safely and with minimal impact. To help us to do so, we asked a select group of James Hay users to place new business on the new platform ahead of the upgrade, and we carried out four dress rehearsals with thousands of tasks replicated.  

However, should you come across any issues, please inform your usual point of contact. We value your feedback and will work to resolve any problems as quickly as possible.

Information regarding any current known issues is published within the platform, ensuring transparency and awareness.
