Shareholders of PARKER SOFTWARE LIMITED
Companies House’s persons-with-significant-control register records Parker Software Holdings Limited, a private company limited by shares (company number 11619296) with a registered address at Innovation Centre 6, Keele University Science Park, Newcastle-Under-Lyme, Staffordshire, ST5 5NS, as the sole current person with significant control of PARKER SOFTWARE LIMITED, notified 22 July 2019, holding “ownership of shares – 75% or more” and “ownership of voting rights – 75% or more.” Zavia’s own shareholder-register data, verified 17 September 2026, corroborates this and records Parker Software Holdings Limited as holding the entire issued share capital of 1,000 ordinary shares of £1 each. Companies House also records two ceased PSC entries, both notified 4 September 2016 and ceased 22 July 2019 when Parker Software Holdings Limited’s interest was notified: Mrs Julia Parker, who held more than 25% but not more than 50% of shares and voting rights, and Mr Stephen David Parker, who held more than 50% but less than 75%.
Ultimate beneficial ownership
Mr Stephen David Parker is identified as the ultimate beneficial owner of PARKER SOFTWARE LIMITED through an indirect ownership chain. Companies House’s persons-with-significant-control register for Parker Software Holdings Limited (company number 11619296) records him as its sole current PSC, notified 12 October 2018, holding 75% or more of that company’s shares and voting rights and the right to appoint or remove its directors; he is British and resident in England. As Parker Software Holdings Limited itself holds 75% or more of the shares and voting rights of PARKER SOFTWARE LIMITED (and, per Zavia’s shareholder-register data, the entire issued share capital), Mr Parker’s effective indirect interest in PARKER SOFTWARE LIMITED is at least 75%; because UK PSC filings report ownership in bands rather than exact percentages, a precise calculated figure is not available.
