What changes in SIC 2026

ONS published UK SIC 2026 in 2026. Its correspondence table maps this code's class (26.51) to:

SIC 2026 code	Heading	Link type
26.51	Manufacture of instruments and appliances for measuring, testing and navigation	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 26511 until it announces a switch.
