Who Owns Opus Broadband? Ownership Structure Explained
OPUS BROADBAND • OWNERSHIP • LIMEFIELD GROUP • UK ISP MARKET
Opus Broadband PLC is controlled by Opus Broadband Topco Limited. Companies House records Limefield Group Limited as owning 75% or more of Opus Broadband Topco Limited.
That means the ownership chain runs through a holding company rather than directly from an individual shareholder. The records also show that Tahir Mohsan’s previous significant control ended in February 2026.

The short answer
The current Companies House ownership structure is:
Opus Broadband PLC
The active broadband company, registered under company number 15546441.
Opus Broadband Topco Limited
The company recorded as having 75% or more of Opus Broadband PLC’s shares and voting rights.
Limefield Group Limited
The active person with significant control of Opus Broadband Topco Limited, also recorded with 75% or more ownership.
In plain English: Limefield Group sits at the top of the ownership chain shown in the current Companies House records.
How the ownership chain works
| Company | Companies House position | Role in the structure |
|---|---|---|
| Opus Broadband PLC | Active company, number 15546441. | Operating company associated with the Opus Broadband ISP brand. |
| Opus Broadband Topco Limited | Recorded as the person with significant control of Opus Broadband PLC. | Holding company above Opus Broadband PLC. |
| Limefield Group Limited | Recorded as owning 75% or more of Topco’s shares. | Top-level corporate controller shown in the current PSC record. |
“Person with significant control” does not always mean an individual person. Companies House can record another company when a corporate entity controls the shares, voting rights or director appointments.
What is Limefield Group?
Limefield Group Limited is the company listed by Companies House as the active person with significant control of Opus Broadband Topco Limited. Its record shows company number 12353167.
The Topco PSC filing records Limefield Group as having ownership of shares of 75% or more. The public record does not, by itself, provide a complete picture of every economic arrangement, financing agreement or minority interest that may exist outside the PSC register.
Accuracy point: this article describes the control information publicly recorded at Companies House. It does not claim that Limefield Group owns every asset, network contract or brand associated with Opus Broadband.
What changed in February 2026?
Companies House filing history shows that Limefield Group Limited was notified as a person with significant control of Opus Broadband Topco Limited on 11 February 2026.
The same record shows Tahir Mohsan’s previous significant control ceased on that date. The filing lists his former control as including 75% or more ownership, 75% or more voting rights and the right to appoint or remove directors.
This is why older articles or company profiles may name Tahir Mohsan, while the current PSC record identifies Limefield Group Limited.
Is Opus Broadband owned by Opus Telecom?
There is no basis in the current ownership records to treat Opus Telecom Limited as the owner of Opus Broadband PLC. Opus Broadband PLC’s PSC record names Opus Broadband Topco Limited, while Topco’s record names Limefield Group Limited.
Company names can be similar, so readers should check the company number and official PSC record rather than relying on the word “Opus” alone.
Current ownership chain
Opus Broadband PLC → Opus Broadband Topco Limited → Limefield Group Limited.
Do not assume a connection
Other companies using the Opus name may be separate legal entities unless official records show otherwise.
Why the ownership matters now
Opus Broadband’s ownership structure has attracted attention because the company was reported to have made an offer of around £100m for TalkTalk’s consumer business.
That reported offer would represent a significant expansion beyond Opus Broadband’s regional network focus. It has not, however, changed the Companies House ownership chain described above, and no completed TalkTalk acquisition has been announced.
