What changes in SIC 2026
ONS published UK SIC 2026 in 2026. Its correspondence table maps this code's class (80.20) to:
| SIC 2026 code | Heading | Link type |
|---|---|---|
| 80.09 | Security activities n.e.c. | 1:1 |
"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 80200 until it announces a switch.
