What changes in SIC 2026
ONS published UK SIC 2026 in 2026. Its correspondence table maps this code's class (27.11) to:
| SIC 2026 code | Heading | Link type |
|---|---|---|
| 27.11 | Manufacture of electric motors, generators and transformers | 1:2 |
| 29.11 | Manufacture of motor vehicle engines | 1:2 |
"1:1" means the class carries over unchanged in scope; other link types mean it was split or merged. Companies House still uses SIC 2007, so keep filing with 27110 until it announces a switch.
