INVINITY ENERGY SYSTEMS LIMITED
Invinity Energy Systems Limited is a private limited company incorporated in Jersey under registration number 92432, with an incorporation date of 8 February 2006. The company was originally registered as Camco International Limited and, under a series of later names, has been the Jersey-incorporated top company of a group focused first on clean-energy investment and, since 2015, on grid-scale energy-storage technology.
The company changed its name to Camco Clean Energy plc in November 2012 and to redT energy plc in November 2015, reflecting a shift toward commercialising redT flow battery technology. On 1 April 2020, redT energy plc merged with Avalon Battery Corporation, a vanadium flow battery developer based in the United States and Canada, through a share-for-share exchange, and the enlarged group was renamed Invinity Energy Systems plc. The group’s audited 2024 accounts record goodwill of £24 million arising from that 2020 merger.
On 9 January 2025, following a Scheme of Arrangement sanctioned by the Royal Court of Jersey under Article 125 of the Companies (Jersey) Law 1991, a newly incorporated England and Wales company, also named Invinity Energy Systems plc (Companies House number 15892542, incorporated 12 August 2024), became the new ultimate parent of the group through a share-for-share exchange, and its shares were admitted to trading on AIM, ticker IES, and the Aquis Stock Exchange Growth Market. As part of that reorganisation, this Jersey company was re-registered as a private company and changed its name from Invinity Energy Systems plc to Invinity Energy Systems Limited. It is therefore no longer the listed parent of the group and is not itself admitted to trading; the 2024 annual report gives its registered address as Third Floor, IFC5, Castle Street, St Helier, Jersey JE2 3BY.
For the year ended 31 December 2024, while it was still the group’s ultimate parent, the company reported consolidated revenue of £5.015 million, down from £22.006 million in 2023, and a consolidated loss for the year of £22.8 million, with an average of around 145 employees across the United Kingdom, Canada and other locations. The group’s principal activity is the design, manufacture and sale of vanadium redox flow batteries for long-duration, grid-scale energy storage, marketed historically as the VS3 product and, following a 2024 commercial launch and a first delivery in December 2024, as the newer ENDURIUM system. These figures relate to the wider Invinity group as reported under this entity for FY2024 and are not necessarily representative of Invinity Energy Systems Limited’s standalone position as a private Jersey subsidiary following the January 2025 reorganisation.

Shareholders
Shareholders of Invinity Energy Systems Limited
Jersey’s company registry, the Jersey Financial Services Commission, returned an access-restricted response (HTTP 403) when its NameSearch and RBN1 company lookups were checked directly for this profile, so no dated shareholder register for Invinity Energy Systems Limited itself, as currently constituted, has been obtained from the Jersey registry. Following the 9 January 2025 redomiciliation, the Company’s own filings describe a share-for-share exchange under which all issued shares in this Jersey company, then Invinity Energy Systems plc, were cancelled, with equivalent shares issued in a newly incorporated England and Wales company also named Invinity Energy Systems plc (Companies House number 15892542); the practical effect is that the new English company now holds the Jersey company’s shares, though the precise percentage has not been separately confirmed from the Jersey registry. The shareholdings quoted below relate to that new, English-incorporated listed parent rather than to Invinity Energy Systems Limited directly, and should not be read as the Jersey company’s own shareholder register. Under Disclosure Guidance and Transparency Rule 5, the parent company disclosed the following holdings of 3% or more of its issued ordinary share capital as at 8 May 2025: National Wealth Fund, 108,695,652 shares, 24.67%; Schroders plc, 60,256,682 shares, 13.68%; Janus Henderson, 22,195,652 shares, 5.04%; Premier Miton, 17,549,672 shares, 3.98%; and Herald Investment Management, 16,446,850 shares, 3.73%. The 2024 Annual Report notes that this list may not represent the current significant shareholdings in the Company and does not purport to be a complete share register.
Data availability
Shareholder information for Invinity Energy Systems Limited itself is Not public: as a private Jersey company it is not subject to the UK Disclosure Guidance and Transparency Rules, and the Jersey Financial Services Commission register could not be accessed for this profile. Shareholder information for the wider Invinity group is Major shareholders only, since the DTR5 notifications summarised above cover only holders above the 3% disclosure threshold in the new UK-incorporated parent, not a complete share register of either company. No individual ultimate beneficial owner is disclosed; the largest reported holder, National Wealth Fund, is a UK public financial institution rather than a natural person, and no complete, dated ownership chain is available to calculate an effective percentage for any natural person.

Data availability
Officer information for Invinity Energy Systems Limited is Restricted for the period since 9 January 2025: the individuals named above governed the wider Invinity group, including this Jersey company, through the 2024 financial year and the report’s signing date, but the entity’s own distinct board as a private subsidiary following the redomiciliation has not been independently confirmed, since the Jersey Financial Services Commission register returned an access-restricted response for this profile.

Group Structure
Group structure of Invinity Energy Systems Limited
Before 9 January 2025, this Jersey company, then named Invinity Energy Systems plc, was the ultimate parent of the Invinity group and controlled, directly or indirectly, the subsidiaries and one associate reported in the Group’s audited “Group Entities” note for the year ended 31 December 2024. Since 9 January 2025, following a Scheme of Arrangement sanctioned by the Royal Court of Jersey and a share-for-share exchange, that position has passed to a newly incorporated England and Wales company, also named Invinity Energy Systems plc (Companies House number 15892542, incorporated 12 August 2024); Invinity Energy Systems Limited is now a subsidiary within that structure rather than its parent. The Jersey Financial Services Commission register returned an access-restricted response (HTTP 403) when checked directly for this profile, so the exact ownership percentage the new parent holds in this Jersey company has not been independently confirmed from the Jersey registry itself, although the redomiciliation mechanics described in the Company’s own filings, involving cancellation of all issued shares in the former plc and their exchange for shares in the new parent, are consistent with full ownership. Separately, one of this Jersey company’s own former direct subsidiaries, an England-registered company also called “Invinity Energy Systems Limited” (formerly Camco Services (UK) Limited, principal activity: support services), should not be confused with Invinity Energy Systems Limited, the Jersey company that is the subject of this profile; the two are distinct legal entities in different jurisdictions that happen to share a name.

Was the Jersey Financial Services Commission register accessible for this profile?
No. The JFSC's NameSearch and RBN1 company lookups returned an HTTP 403 access-restricted response when checked directly for this profile, so this profile relies on the Invinity group's own regulatory filings, annual report and official announcements rather than a direct Jersey registry extract.
Why does this profile show financial results for a private Jersey company?
The revenue, loss and employee figures shown relate to the wider Invinity group as reported for the year ended 31 December 2024, when this Jersey company was still the group's ultimate parent and reporting entity. They are consolidated group figures rather than a standalone Jersey company result, and they predate the 9 January 2025 redomiciliation.
Is this company profile kept up to date?
Zavia.ai periodically reviews and re-verifies published company information such as this profile against the sources cited, including official registries and regulatory filings, and updates it when new, reliably sourced information becomes available.
