TSC 2026 is final

The TSC 2026 has been determined. During the consultation no questions or comments were received regarding the proposed changes. There are also no additional changes. The TSC 2026 is therefore identical to the previously published TSC 2026 consultation version.

Where possible the updated TSC uses the definitions as used in the new Gas Regulation and the Energy Act, which will apply from January 1 2026.

The TSC and all appendices can be found here. They will be in force as of 01-01-2026.
