The register
The register lists Nz Engines Limited in Rainham 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).
Companies House lists it as NZ Engines Limited, number 10644002, incorporated 2017: 9 years of filings behind the name. The registered office is at Unit 2 & 3 9 Cold Harborough Lane, Ferry Lane, Rainham, Essex, RM13 9YH, RM13 9YH. By its SIC codes the business is in motor trade and vehicle repair.
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.
