ELFAB LIMITED
Elfab Limited is a private limited company registered in England and Wales under company number 00853197. It was incorporated on 1 July 1965, and its Companies House record shows the company as Active as of September 2026.
The company’s registered office is at Alder Road, West Chirton Industrial Estate, North Shields, Tyne & Wear, NE29 8SD, United Kingdom. Companies House classifies Elfab Limited’s business activity under UK SIC code 25990, manufacture of other fabricated metal products not elsewhere classified. Consistent with this classification, the company designs, tests and manufactures rupture discs, explosion vents and associated burst-detection systems that provide pressure relief and explosion protection for industrial plant and process equipment. Its stated customer base is concentrated in the chemical, pharmaceutical, oil and gas, and food-processing industries, and its pressure-relief technology is also used in specialist OEM applications, including space-launch systems and automotive safety devices.
Elfab Limited operates from a single registered site in North Shields, in North East England, and supplies customers internationally. It is not itself listed on any stock exchange, and no ticker symbol applies to this legal entity.
An Active status on the UK register does not by itself confirm that the company is currently trading. Elfab Limited filed full annual accounts for the financial year ended 31 March 2025 (filed with Companies House on 11 November 2025), and its most recent confirmation statement was made up to 14 October 2025 (filed 28 October 2025); no revenue or employee-count figures were extracted from these filings for this profile.

Shareholders of Elfab Limited
Elfab Limited’s UK Persons with Significant Control (PSC) register discloses one registrable person: Halma plc (company number 00040932), recorded as holding 75% or more of the company’s shares, with effect from 6 April 2016. Companies House’s PSC regime reports ownership in statutory bands rather than exact percentages, so the precise shareholding beyond this threshold is not stated in the PSC filing itself. This is consistent with company share records showing 1,060,000 ordinary shares of GBP 1.00 each, entirely held by Halma plc. No other UK-registered shareholder or PSC is disclosed for this entity, and the disclosure reflects direct company-level share ownership.
Ultimate beneficial ownership
Halma plc is a public limited company listed on the London Stock Exchange (ticker HLMA) and a constituent of the FTSE 100 index. As a company subject to public-markets disclosure requirements, Halma plc is not itself required to identify a further individual ultimate beneficial owner under the UK PSC regime, and no natural-person UBO is disclosed above Halma plc in Elfab Limited’s ownership chain. Halma plc is therefore the highest disclosed entity of significant control over Elfab Limited.
Data availability
Disclosure is Full for this company: the direct shareholder is confirmed via both the PSC register and share records, and the absence of a further individual UBO reflects Halma plc’s status as a publicly listed company rather than a gap in available information.

Group Structure
Group structure of Elfab Limited
Companies House filings confirm that Elfab Limited is not an independent company. Its Persons with Significant Control (PSC) register identifies Halma plc (company number 00040932), a UK public limited company incorporated in 1894 and listed on the London Stock Exchange, as holding 75% or more of Elfab Limited’s shares since 6 April 2016; this is corroborated by company share records showing Halma plc holding 100% of Elfab Limited’s ordinary share capital. No intermediate UK-registered holding company between Elfab Limited and Halma plc was identified in Companies House filings, so Halma plc is treated here as both the immediate and ultimate identified parent. No subsidiaries of Elfab Limited itself were identified in Companies House filings.
Halma plc’s own website groups Elfab’s rupture-disc and explosion-protection business together with Oseco under a shared "OsecoElfab" commercial brand within Halma’s Safety sector. Halma’s website does not identify Oseco as a separately registered UK legal entity or clarify the corporate-legal relationship between the two businesses, so this is presented as brand and commercial context only, and is not presented as a verified sister-company relationship.
