What this notice means
A winding-up petition asks the court to close a company and place it into compulsory liquidation, most often because a debt has gone unpaid. If the court makes a winding-up order, control passes to the Official Receiver or an appointed liquidator, the company's bank accounts are frozen and its assets are sold to repay creditors.

How does this notice affect you?
Choose what applies and we'll point you at the right next step.
A written-off invoice rarely stops at the company that failed. The supplier left short is often the next business in difficulty — and the earlier that's dealt with, the more options stay open. If SIRIUS OPEN SOURCE LTD owed you money, it's worth checking where that leaves you.
Unpaid wages, holiday pay and statutory redundancy are claimed from the government's Redundancy Payments Service, not from K2. The insolvency practitioner named in this notice should send you a case reference — you'll need it to claim.
K2 has backed and restructured UK businesses since 1990, including buying trade and assets out of distress. These situations move in days rather than months, so if you're looking at SIRIUS OPEN SOURCE LTD or something similar, start the conversation early.
If your business is under pressure — creditors circling, a petition threatened, or cash running out — acting early changes the outcome. K2 has helped UK directors turn things around since 1990. Talk to us in confidence.
Is your own business showing the same warning signs?
Falling margins, stretched creditors, overdue filings and HMRC arrears usually appear months before a Gazette notice. Directors who act at that stage keep far more options open, from an informal turnaround to a CVA or restructuring plan.

The company owes me money — what can I do?
You are a creditor in the process. The insolvency practitioner named in the notice will write to known creditors and invite claims; if you have not heard from them, contact them with your invoices. Unsecured creditors rank after fixed-charge holders, the costs of the insolvency, preferential creditors and floating-charge holders, so recovery depends on what is left in the estate.
I worked there — how do I claim what I am owed?
Unpaid wages, holiday pay and statutory redundancy are claimed from the government's Redundancy Payments Service, not from the company or from K2. The insolvency practitioner named in this notice should give you a case reference to claim with.
