IDOX PLC
Idox Limited is a private company limited by shares registered in England and Wales under company number 03984070. It was incorporated on 26 April 2000 and its Companies House status is Active. Its registered office is Unit 5, Woking 8, Forsyth Road, Woking, Surrey GU21 5SB.
The entity has carried five registered names. It was incorporated as I-Documentsystems plc, became Chartbuild plc on 18 October 2000, I-Documentsystems Group plc on 15 November 2000 and Idox plc on 10 September 2004. It was renamed Idox Limited on 3 July 2026, the same day it filed a form RR02 and received a certificate of re-registration from a public limited company to a private limited company. The name shown at the head of this page, Idox plc, is the former name.
Its registered SIC code is 64209, activities of other holding companies not elsewhere classified, and its own FY2025 financial statements state that the company has no employees. Idox Limited heads the Idox group, which supplies planning, building control, land charges, licensing, electoral and social care case-management software and geospatial data services to UK local authorities and public bodies, and engineering document management to asset-intensive sectors such as power, nuclear and infrastructure. Consolidated group revenue for the year ended 31 October 2025 was £89.8m (2024: £87.6m), adjusted EBITDA £27.0m and the average number of employees 723 (2024: 682). Revenue by customer location was £82.1m United Kingdom, £4.6m USA, £2.3m rest of Europe and £0.8m rest of world. Those are consolidated group figures; the company’s own separate result for FY2025 was a loss of £4.9m.
Idox shares traded on AIM under the ticker IDOX, with Peel Hunt LLP as nominated adviser and broker. On 28 April 2026 Idox applied to the London Stock Exchange under AIM Rule 41 to cancel that admission, and the cancellation took effect at 7.00am on 29 May 2026. The accounting reference date was afterwards extended from 31 October 2026 to 31 December 2026 by a form AA01 filed on 11 September 2026.
The group’s UK public-sector work is visible on Contracts Finder, where buyers publish awarded contracts under the Idox name: North Yorkshire Council published a £2,624,054 award for Idox Uniform on 14 October 2024 running to 29 September 2029, Basingstoke and Deane Borough Council £548,180 on 15 March 2025, Uttlesford District Council £526,000 on 1 September 2025 and Mid Sussex District Council £448,778 on 1 April 2026. Twenty-two charges have been registered against company 03984070 and Companies House records all twenty-two as satisfied, the most recent two on 7 May 2026.

Shareholders of Idox Limited
Idox Limited has one registrable shareholder on the public record. Companies House shows Frankel UK Bidco Limited, registered in England under number 16802556, as a person with significant control notified on 5 May 2026, holding more than 75% of the shares and more than 75% of the voting rights and holding the right to appoint or remove directors. The UK register publishes bands rather than exact percentages, so no precise figure is available. Until that filing the company carried the opposite entry: a statement made on 23 October 2019 that it knew of no registrable person or relevant legal entity, which was withdrawn on 5 May 2026. That statement is the normal position for a widely held listed company, and it is the reason no shareholder appeared on this register before 2026.
The last published analysis of the wider shareholder base is the directors’ report in the audited annual report for the year ended 31 October 2025, approved on 16 February 2026, which lists interests of 3% or more of the issued share capital as at 31 October 2025. Idox was a UK issuer admitted to AIM, so vote-holder notifications were made under DTR 5 at a 3% threshold rather than the 5% threshold that applies to non-UK issuers. The list therefore covers only reportable holdings, never the whole shareholder base.
| Holder | Shares | % of issued share capital |
|---|---|---|
| Octopus Investments | 72,034,040 | 15.60% |
| Long Path Partners | 56,876,997 | 12.32% |
| Canaccord Wealth | 47,965,753 | 10.39% |
| Soros Fund Management | 43,331,451 | 9.39% |
| Rathbones | 34,769,997 | 7.53% |
| Gresham House Asset Management | 31,947,843 | 6.92% |
| Mission Trail Capital Management | 13,830,107 | 3.00% |
That list has been superseded. On 28 October 2025 Frankel UK Bidco Limited and Idox announced a recommended all-cash acquisition under Rule 2.7 of the Takeover Code at 71.5 pence per share, which the annual report states valued Idox at £339.5m. A scheme document was published on 20 November 2025; the court and general meetings were adjourned on 15 December 2025; on 5 January 2026 the structure was switched, with the consent of Idox and the Takeover Panel, to a contractual takeover offer, whose offer document was posted on 15 January 2026. The offer was declared unconditional on 21 April 2026. At 5.00pm on 11 May 2026 valid acceptances covered 405,036,497 Idox shares, approximately 90.2% of the shares to which the offer related, and Frankel exercised the statutory squeeze-out under sections 979 and 980 of the Companies Act 2006. There were 461,682,046 ordinary shares of 1p in issue at 16 April 2026; a statement of capital filed on 22 April 2026 records an allotment taking the aggregate nominal ordinary capital to £4,748,428.85.
Ultimate beneficial ownership
No natural person is registered as a person with significant control of Idox Limited. Above the immediate parent, each company in the chain filed on 22 October 2025 at the same “75% or more” band: Frankel UK Bidco Limited (16802556) is held by Frankel UK Midco 2 Limited (16802421), which is held by Frankel UK Midco 1 Limited (16802301), which is held by Frankel UK Holdco Limited (16802144). Frankel UK Holdco Limited’s own register names one natural person, William Brennan, whose nationality is recorded as American and place of residence as the United States, notified on 22 October 2025 on the ground of significant influence or control rather than on a shareholding. That ground carries no percentage band, so no effective ownership percentage can be calculated through the chain, and he is not registered as a person with significant control of Idox Limited itself. The offeror’s own announcements state that Frankel UK Bidco Limited is indirectly owned by four Long Path funds: Long Path Co-Investment Fund #6, LP; Long Path Smaller Companies Fund, LP; Long Path Smaller Companies Master Fund, Ltd.; and Long Path Opportunities Fund II, LP. No split between those funds is published, so no single ultimate beneficial owner of Idox Limited is established on the public record.
Data availability
Partial. The United Kingdom does not publish a share register, so holdings are disclosed only in bands above the 25% PSC threshold; the pre-takeover holder list is historical, dated 31 October 2025, and covered only holdings at or above the 3% notification threshold. The shareholder rows stored on this page do not reconcile and should not be read as ownership: ten institutional fund rows totalling 2,719,171 shares, about 0.6% of the 461,682,046 shares then in issue, carry percentages summing to roughly 100%, including Artisan International Explorer Fund shown at 69.59% for 1,892,187 shares, which is about 0.41% of the shares in issue. Those rows are stamped 28 September 2026, four months after the shares ceased to be admitted to trading and the company came under a single 75%-plus holder.

Directors and officers of Idox Limited
Companies House records 36 appointments for company 03984070, of which 33 have ended, leaving three current officers. They are Anoop Kang, appointed director on 16 March 2022; Jonathan Legdon, appointed director on 25 October 2024; and Thérèse Laing, appointed secretary on 26 July 2024. The register records the nationality of both current directors as British and their place of residence as England; it publishes no nationality for the serving secretary. The annual report for the year ended 31 October 2025 describes Anoop Kang as Group Chief Financial Officer and Jonathan Legdon as Group Chief Operating Officer; Companies House itself records no occupation for either. All three correspondence addresses are the company’s registered office in Woking and are service addresses, not home addresses. There are no corporate officers in post. The register was read on 29 September 2026.
Recent officer changes
- Five appointments ended on 29 May 2026, the day the company’s shares ceased to be admitted to trading on AIM: Christopher Michael Renwick Stone, director, appointed 22 November 2018; David John Meaden, director, appointed 1 June 2018; Mark Francis Milner, director, appointed 29 July 2024; Alice Sarah Louise Cummings, director, appointed 14 April 2020; and Ruth Paterson, secretary, appointed 30 August 2018. The four TM01 forms were filed on 3 June 2026 and the TM02 on 9 June 2026.
- Jonathan Legdon was appointed a director on 25 October 2024. He remains in post.
- Thérèse Laing was appointed company secretary on 26 July 2024, serving alongside Ruth Paterson until the latter’s appointment ended on 29 May 2026.
Data availability
Full for this jurisdiction. Companies House publishes current and former officers with appointment and termination dates, and publishes nationality, place of residence and month and year of birth for directors; it publishes neither nationality nor date of birth for company secretaries, and it does not publish occupation. Two defects in the officer data stored for this page should be noted. First, it holds 29 of the register’s 36 appointments and marks Mark Francis Milner as an active director although his appointment ended on 29 May 2026 and the TM01 was filed on 3 June 2026; four of the five terminations of that date were captured and his was not. Second, the corporate officer L.C.I. Secretaries Limited holds both a secretary and a director appointment on the register for 26 April 2000 to 13 November 2000, where the stored data records only the secretary role. Separately, the register itself carries a duplicate entry for one former director showing an appointment and a resignation on the same day, 14 April 2020, alongside that person’s real appointment, so counts of appointments taken from the register need de-duplicating.

Recent structural changes
- 12 May 2025: acquisition of Trojan Consultants Limited (01542629), which trades as Plianz and supplies health and social care software, for an initial enterprise value of £7.65m in cash.
- Shortly after the 31 October 2025 year end: the asset purchase of Ayup for £0.3m in cash. This was a purchase of assets, not of shares, so it adds no legal entity to the structure.
- 5 May 2026: change of parent. Frankel UK Bidco Limited was notified as the company’s person with significant control, replacing the withdrawn statement that there was no registrable person or relevant legal entity.
Data availability
Partial, and better than the stored data suggests. The parent chain is fully documented because every UK company must maintain a PSC register, but those entries give bands rather than percentages, so no exact ownership figure exists for any link in it. The subsidiary list is complete and audited but is dated 31 October 2025 and carries registration numbers only where this review could match them at Companies House. The corporate tree stored for this page is unreliable in three ways: it shows no parent at all, so the 2026 change of control is invisible in it; it omits Idox France SARL, McLaren Software Inc, CT Space Inc and Citadon Inc; and it contains three entities that appear in neither the FY2024 nor the FY2025 audited subsidiary note – Sponge Belgium (Belgian enterprise number 0456.754.093, which the Crossroads Bank for Enterprises shows as an active company with a 30 April financial year end, against Idox’s 31 October), Compunet Ltd and 6PM Agencies Ltd. Those three should not be treated as current group members. The stored tree also records Idox India Private Limited under “AAECC6560A”, which is an Indian permanent account number, not a corporate identification number.
