The register
The register lists Greenstorm in Birmingham as a licensed sponsor on Skilled Worker, an entry that goes back to at least 2026. The register records its rating as Worker (A rating).
Greenstorm Limited is the registered name (Companies House number 12629932), a private limited company on the register since 2020. The registered office is at Grosvenor House, 11 St. Pauls Square, Birmingham, B3 1RB, B3 1RB. By its SIC codes the business is in construction.
What the licence tells a candidate is that the door is not locked. Whether it is open this month is a question for Greenstorm's own careers page and the job boards, and the answer changes with the season and the order book.
