What changes in SIC 2026
ONS published UK SIC 2026 in 2026. Its correspondence table maps this code's class (25.21) to:

|---|---|---|
| 25.21 | Manufacture of central heating radiators, steam generators and boilers | 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 25210 until it announces a switch.
