A licence says an organisation may sponsor; it does not say it is hiring today. The way to find out is the same as for any employer: the careers page, the job boards, and a direct approach with a UK-style CV that says early that sponsorship would be needed.
What a licence means
They can sponsor. That is all it says.
A sponsor licence lets an organisation assign a Certificate of Sponsorship to a worker on the routes it covers. It does not mean Siderise Insulation Ltd is hiring from abroad this month, only that it can, and has been checked by the Home Office to do so.
How to approach them
Make the certificate easy
The employer assigns the certificate; you supply what it needs. Certificates, references, your English level and a clear licence position, all ready, is what makes Siderise Insulation Ltd say yes to the sponsored candidate over the unsponsored one.
