HALO (GROUP HOLDINGS) REALISATIONS PLC
HALO (GROUP HOLDINGS) REALISATIONS PLC is a public limited company registered in England and Wales under company number 06409712, according to Companies House. The company was incorporated on 25 October 2007 as New Portland Plc, and was subsequently renamed Portland Gas Plc in January 2008, InfraStrata Plc in December 2009, Harland & Wolff Group Holdings Plc in September 2021, and, on 12 February 2025, HALO (Group Holdings) Realisations Plc. Companies House records the company’s current status as “In Administration”; Gavin Park and Matt Cowlishaw of Teneo Financial Advisory Limited were appointed joint administrators on 27 September 2024, and the company’s registered office is now recorded care of Teneo Financial Advisory Limited, The Colmore Building, 20 Colmore Circus Queensway, Birmingham, B4 6AT.
Companies House classifies the company’s principal activity under UK Standard Industrial Classification code 70100, activities of head offices. The business began as a developer of an underground natural gas storage project at Islandmagee, Northern Ireland, and from 2019 traded as Harland & Wolff, operating shipyards at Belfast, Appledore, Methil and Arnish that provided shipbuilding, ship repair, fabrication and heavy-engineering services, including construction work on Fleet Solid Support vessels for the Royal Fleet Auxiliary. On 27 January 2025, Navantia UK Limited completed the acquisition of the Harland & Wolff shipbuilding business and assets at all four sites, a transaction reported by Navantia UK as preserving more than 1,000 jobs.
The company’s ordinary shares traded on the AIM market of the London Stock Exchange under the ticker HARL until they were cancelled from trading on 28 October 2024, following the September 2024 administration. As at the information date below, Companies House shows the company’s accounts and confirmation statement as overdue; this registry status describes the company’s continuing legal existence and does not by itself indicate whether it retains any operating activity following the sale of its shipbuilding business.

Shareholders
Shareholders of HALO (Group Holdings) Realisations Plc
HALO (Group Holdings) Realisations Plc’s persons-with-significant-control (PSC) register at Companies House shows no active PSC entries. The company instead holds a filed exemption statement, dated 26 June 2017, recording that “the company knows or has reasonable cause to believe that there is no registrable person or registrable relevant legal entity in relation to the company” – a disclosure route available at the time to companies whose voting shares were admitted to trading on a specified market such as AIM. The company’s shares traded on AIM under the ticker HARL until they were cancelled from trading on 28 October 2024, following its entry into administration; no replacement PSC statement reflecting the company’s current, unlisted position has since been filed. No individual major shareholder holdings are separately published in the sources reviewed for this profile.
Data availability
Classification: Historical. The only PSC-related filing on record predates both the company’s September 2024 administration and its October 2024 AIM delisting by several years and may no longer reflect its current ownership position; no updated shareholder or beneficial-ownership filing was located.

Companies House publishes nationality and country of residence as separate fields for both active directors; occupation, as distinct from legal role, is not separately published for these appointments, and the correspondence address on file (The Colmore Building, 20 Colmore Circus Queensway, Birmingham) is the administrators’ service address, not a residential address.

Group Structure
Group structure of HALO (Group Holdings) Realisations Plc
Companies House filings confirm HALO (Group Holdings) Realisations Plc as the ultimate identifiable parent of a small corporate group, most of which entered administration alongside it. Persons-with-significant-control filings verify the company as holding 75% or more of the shares and voting rights, together with the right to appoint or remove directors, in both Infrastrata UK Limited (company number 06030687, a gas-storage and pipeline business registered in England and Wales, notified 6 April 2016) and HALO (Holdings) Realisations Limited (company number 12810172, formerly Harland & Wolff Group Holdings Limited, notified 13 August 2020). HALO (Holdings) Realisations Limited’s own PSC filing in turn confirms it holds 75% or more of the shares and voting rights in HALO (Belfast) Realisations Limited (company number NI664860, formerly Harland and Wolff (Belfast) Limited, notified 19 October 2020), making that company a verified indirect subsidiary of HALO (Group Holdings) Realisations Plc. The underlying shipbuilding business and assets at the group’s Belfast, Appledore, Methil and Arnish sites were sold to Navantia UK Limited on 27 January 2025; this was a business-and-asset sale rather than a change of legal ownership of the companies themselves, all of which remain in administration. No parent company of HALO (Group Holdings) Realisations Plc was identified; its own PSC filing records no registrable person or entity. This overview reflects Companies House filings reviewed 10 September 2026.

Data availability
Classification: Partial. Companies House PSC filings verify a two-tier chain of subsidiaries down to HALO (Belfast) Realisations Limited, each recorded at the 75%-or-more ownership band rather than as an exact percentage; no precise indirect percentage is calculated because banded disclosures do not represent exact figures. The ownership links from HALO (Holdings) Realisations Limited to the group’s other former shipyard companies (Appledore, Methil and Arnish) were not independently verified for this profile and are therefore omitted from the table above.
