What changes in SIC 2026
ONS published UK SIC 2026 in 2026. Its correspondence table maps this code's class (64.30) to:
| SIC 2026 code | Heading | Link type |
|---|---|---|
| 64.31 | Activities of money market funds | 1:4 |
| 64.32 | Activities of open-ended non-money market funds | 1:4 |
| 64.33 | Activities of closed-ended non-money market funds | 1:4 |
| 64.34 | Activities of trust, estate and agency accounts | 1:4 |
"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 64304 until it announces a switch.
