SOC 3112 is an eligible occupation, but we are only 50% sure that is the right code. United Utilities is a licensed sponsor, so if the code fits, the role should qualify. Check the occupation eligibility rules against what the job actually involves.
Worth checking: this could also be SOC 5224 (Precision instrument makers and repairers), which is not on the eligible-occupation list. Ask United Utilities what the duties actually are.
