Nucleus

Nucleus Financial operates as a group holding several specialist retirement and platform businesses. The primary adviser-facing platform is Nucleus Wrap, with a newer dedicated retirement platform launched in recent years. The group also owns James Hay, Curtis Banks, and Talbot and Muir for SIPP and SSAS administration, plus Third Financial for enterprise platform software and Dunstan Thomas for wealth management technology. Each brand operates with meaningful product autonomy but benefits from shared group resources and distribution.

Nucleus Financial was a publicly traded company on the London Stock Exchange's AIM market before being acquired by private equity firm HPS Investment Partners and taken private in 2021. It is currently privately held and not listed on any public exchange.

Nucleus was founded by a consortium of adviser firms specifically to align platform economics with adviser and client interests. The group now uniquely offers multiple distinct platform and pension administration brands under a single independent structure, enabling it to serve firms with different specialisms — from pure wrap to complex commercial-property SSAS — through bespoke combinations of its owned infrastructure, rather than a single monolithic platform product.

Nucleus's current operations are focused entirely on the UK market. All regulated entities, platform operations, and pension administration services are UK-domiciled and designed for UK-resident clients and UK-regulated financial advisers. There is no disclosed operational presence outside the United Kingdom.

Nucleus and its subsidiary brands are authorized and regulated by the UK Financial Conduct Authority. The group's entities operate with permissions covering platform services, pension scheme administration, and financial technology provision. James Hay and Curtis Banks additionally maintain specialist permissions and trustee company registrations required for SIPP and SSAS administration under HMRC and The Pensions Regulator rules.
