Which SIC code fits a control panel or switchgear assembly business?
Most panel builders use 27900. An assembled control panel counts as electrical equipment, and the narrower codes for motors and components rarely match assembly work. Some builders also list an electrical installation code from division 43, because they commission panels on site. Both approaches are common and fine. You select SIC codes yourself and Companies House applies no test of accuracy.
