What changes in SIC 2026

ONS published UK SIC 2026 in 2026. Its correspondence table maps this code's class (27.90) to:

SIC 2026 code	Heading	Link type
27.11	Manufacture of electric motors, generators and transformers	1:4
27.90	Manufacture of other electrical equipment	1:4
29.31	Manufacture of electrical and electronic equipment for motor vehicles	1:4
32.99	Other manufacturing n.e.c.	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 27900 until it announces a switch.
