Topaz Group Holdings Limited: Corporate Structure
Executive summary
TOPAZ GROUP HOLDINGS LIMITED (company number 15819783) operates as the principal holding vehicle for a UK automotive detailing group comprising 9 direct operating subsidiaries across England and Scotland. Incorporated on 4 July 2024, the company is owned in equal 25% to 50% tranches by three corporate entities: Adivo Investments Limited, Mninv Limited, and Nn Holdings Limited. Upstream PSC filings trace ultimate control to individual owners Mrs Sharmeen Ameer Aka, Miss Mariam Ameer, Miss Zayna Ameer, Mr Mazin Naamo, and Mr Nabil Naamo.
Corporate lawyers, secured lenders, and compliance officers conducting KYC and AML checks under MLR 2017 frequently hit an information barrier when investigating holding companies. Companies House is designed strictly as an upward-pointing index. An official registry profile shows a company's officers, share capital, and recorded persons with significant control (PSCs), but it does not index downward equity holdings. To evaluate the commercial credit risk, operational asset footprint, or corporate guarantee strength of a holding company, practitioners require a complete corporate structure chart derived from reverse PSC matching.

What a standard Companies House search reveals
When searching for TOPAZ GROUP HOLDINGS LIMITED via the primary public register, the record provides company status, classification codes, statutory officers, and registered PSC filings. It confirms the entity is active, registered under SIC codes 64209 (activities of financial holding companies), 64301 (activities of investment trusts), and 70229 (management consultancy activities other than financial management).
Under Part 21A of the Companies Act 2006, the register reflects who controls the company. The public record shows two active directorships:
- Mr Mazin Naamo: appointed director on 4 July 2024; British nationality; resident in the United Kingdom; born September 1981.
- Mr Nabil Naamo: appointed director on 4 July 2024; British nationality; resident in the United Kingdom; born February 1985.
Between 4 July 2024 and 22 May 2025, the company's PSC register recorded Mr Nabil Naamo, Mr Mazin Naamo, and Mrs Sharmeen Ameer Aka as individual persons with significant control, each holding 25% to 50% ownership bands. On 22 May 2025, these individual entries ceased, and three corporate entities were notified as registrable corporate PSCs:
1. Adivo Investments Limited (company number 11696438): holding 25% to 50% of shares and 25% to 50% of voting rights.
2. Mninv Limited (company number 16255434): holding 25% to 50% of shares and 25% to 50% of voting rights.
3. Nn Holdings Limited (company number 16259505): holding 25% to 50% of shares and 25% to 50% of voting rights.
Crucially, a manual search stops here. Companies House displays nothing on this entry about the operating locations, subsidiaries, or assets managed under this corporate umbrella.
Downstream subsidiaries revealed by reverse PSC search
To find subsidiaries of a company, standard registry searches fail because corporate filings only point upwards to controllers. Corp Intel resolves this structural gap by ingesting the full UK register and mapping downstream equity: every UK company naming TOPAZ GROUP HOLDINGS LIMITED as a corporate PSC is linked automatically.
This reverse PSC search establishes that TOPAZ GROUP HOLDINGS LIMITED controls 9 operational trading companies across the UK. Each entity delivers car care, detailing, and paint protection services across different territories. None of these 9 subsidiaries currently own second-tier subsidiaries (own subsidiary count is 0).
| Company Name | Number | Status | Control Band | Own Subsidiaries |
| :--- | :--- | :--- | :--- | :--- |
| TOPAZ DETAILING LIMITED | 07100058 | Active | 75-100% shares | 0 |
| TOPAZ DETAILING (BRISTOL) LIMITED | 11019810 | Active | 75-100% shares | 0 |
| TOPAZ DETAILING (HATFIELD) LIMITED | 15113566 | Active | 75-100% shares | 0 |
| TOPAZ DETAILING (MIDLANDS) LTD | 10296910 | Active | 50-75% shares | 0 |
| TOPAZ DETAILING (LEEDS) LIMITED | 10234653 | Active | 75-100% shares | 0 |
| TOPAZ DETAILING (SCOT) LIMITED | 15850846 | Active | 75-100% shares | 0 |
| TOPAZ DETAILING (SOUTHAMPTON) LIMITED | 13460939 | Active | 75-100% shares | 0 |
| TOPAZ DETAILING (MANCHESTER) LIMITED | 16381379 | Active - proposal to strike off | 75-100% shares | 0 |
| TOPAZ DETAILING (PENINSULA) LTD | 15638939 | Active | 75-100% shares | 0 |
Eight of the entities are held under a controlling interest band of 75% to 100% shares, providing the holding company with full unilateral passing power for special resolutions. TOPAZ DETAILING (MIDLANDS) LTD is held within the 50% to 75% band, indicating potential joint-venture minority equity held locally.
One entity within the downstream group warrants specific operational note: TOPAZ DETAILING (MANCHESTER) LIMITED (16381379), incorporated on 11 April 2025, carries the public status "Active - proposal to strike off". In credit underwriting, trade risk assessments, or pre-acquisition scoping, an active striking-off proposal on a group subsidiary requires direct review against The Gazette notices to confirm whether the action is voluntary under section 1003 of the Companies Act 2006 or compulsory registrar action.
Who sits at the top: Upstream ownership and UBOs
Tracing the ownership chain above TOPAZ GROUP HOLDINGS LIMITED requires examining the PSC registers of its three corporate holding entities. Each entity points to specific individuals who form the ultimate beneficial ownership (UBO) tier under the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017.
Tier 1: Intermediate corporate owners
- Adivo Investments Limited (11696438): holds 25% to 50% shares and voting rights in TOPAZ GROUP HOLDINGS LIMITED.
- Mninv Limited (16255434): holds 25% to 50% shares and voting rights in TOPAZ GROUP HOLDINGS LIMITED.
- Nn Holdings Limited (16259505): holds 25% to 50% shares and voting rights in TOPAZ GROUP HOLDINGS LIMITED.
Tier 2: Ultimate beneficial owners
Examining the PSC filings of the three intermediate entities identifies five distinct individual beneficial owners:
- Adivo Investments Limited ownership:
- Mrs Sharmeen Ameer Aka: holds 25% to 50% of shares, 75% to 100% of voting rights, and the right to appoint and remove directors.
- Miss Mariam Ameer: holds 25% to 50% of shares.
- Miss Zayna Ameer: holds 25% to 50% of shares.
- Mninv Limited ownership:
- Mr Mazin Naamo: holds 75% to 100% of shares, 75% to 100% of voting rights, and the right to appoint and remove directors.
- Nn Holdings Limited ownership:
- Mr Nabil Naamo: holds 75% to 100% of shares, 75% to 100% of voting rights, and the right to appoint and remove directors.
Because Mrs Sharmeen Ameer Aka exercises 75% to 100% voting power and board appointment rights in Adivo Investments Limited, she controls that intermediate entity's 25% to 50% block in the parent holding company. Mr Mazin Naamo and Mr Nabil Naamo each hold absolute control over their respective holding vehicles, which mirror their roles as statutory executive directors of TOPAZ GROUP HOLDINGS LIMITED.
Why group structure matters for legal and credit due diligence
Investigating an organisation solely at the parent company tier creates substantial blind spots for transactional advisers. A parent company lookup shows balance-sheet investments in subsidiaries, but operating risk sits in trading entities.
1. Counterparty contracting and ring-fencing
Commercial suppliers and landlord leasing teams must verify which legal entity enters into commitments. While TOPAZ GROUP HOLDINGS LIMITED is the top-tier entity, trading operations, customer receivables, equipment leasing, and premises leases reside within operating companies such as TOPAZ DETAILING LIMITED or regional entities like TOPAZ DETAILING (BRISTOL) LIMITED. Contracting with the wrong entity can leave a supplier unsecured if assets sit elsewhere.
2. Banking, charges, and debentures
Lenders assessing creditworthiness require full visibility of encumbered assets. A parent entity might appear free of debt, while underlying subsidiaries carry fixed and floating charges over equipment, stock, and book debts. Lenders must conduct a company charge check across each subsidiary to evaluate intercompany cross-guarantees or prior ranking security registered at Companies House.
3. Solvency contagion and striking-off risk
Where an operating entity like TOPAZ DETAILING (MANCHESTER) LIMITED faces strike-off procedures, counterparties must establish whether this reflects operational consolidation, dormant company cleanup, or unresolved liabilities. If a trading counterparty is litigating an unpaid debt, running a winding up search or checking insolvency registers ensures enforcement actions are not pending against group entities.
Practical due diligence checklist: Analysing a group structure
When onboarding or reviewing a mid-market corporate group with holding structures, professionals should apply this four-step verification method:
1. Map downstream subsidiaries via reverse PSC search: Query the parent company number across all UK corporate filings to identify all trading entities naming it as a registrable controller.
2. Verify trading status and register health: Confirm whether any subsidiaries show flags such as "Active - proposal to strike off", late filing notices, or administration markers.
3. Inspect the upstream chain to UBO level: Trace each corporate PSC back to living individuals holding 25% or more voting rights or board appointment powers to meet MLR 2017 regulatory compliance.
4. Audit asset and encumbrance distributions: Review the charges register for all identified subsidiaries to determine whether group borrowings are secured against operational plant, premises, or intellectual property.
How professionals map complex UK groups
Traditionally, mapping a group structure like TOPAZ GROUP HOLDINGS LIMITED required hours of manual cross-referencing. A corporate intelligence analyst had to download the parent company's latest filed group accounts, scroll to the subsidiary notes, note each entity number, and manually search each one on Companies House. If group accounts were filed under small-company audit exemptions or omitted recent incorporations like TOPAZ DETAILING (MANCHESTER) LIMITED or TOPAZ DETAILING (SCOT) LIMITED, manual reviews missed parts of the group.
Corp Intel continuously aggregates and indexes the entire Register of Companies and the Persons with Significant Control register. By querying backwards from the parent entity, the system reconstructs the entire group tree in seconds, displaying live company statuses, control bands, and upstream UBO linkages without relying on historic accounting filings.

For conveyancers, corporate lawyers, and lenders
Uncovering downstream subsidiaries and upstream controllers is essential prior to transaction completion, facility agreement execution, or high-value supplier onboarding. Relying on self-declared org charts creates compliance and credit exposure if unrecorded charges, active strike-off notices, or undisclosed corporate controllers exist.
