Updated for IGEM/UP/2 Edition 4
A key feature of the 2026 NICEIC Non-Domestic Gas Safety On Site Guide Version 12 is the incorporation of changes introduced by IGEM/UP/2 Edition 4.
IGEM/UP/2 covers installation pipework on industrial and commercial premises, making the revised information particularly relevant to engineers involved with the installation and assessment of non-domestic gas pipework.
The updated Chapter 6 includes revised information relating to pressure test points, stainless steel press-fit systems, jointing methods, permitted pipework locations and corrosion protection.
Updated Stainless Steel Press-Fit Pipework Guidance
Version 12 includes additional information concerning stainless steel pipework jointed using press-fit fittings.
The revised guidance specifies a maximum pressure regime of 1 bar for internal stainless steel pipework using press-fit fittings. The existing 5 bar pressure provision is retained but is clarified as applying to external pipework.
Table 6.3, covering jointing for carbon and stainless steel pipework, has also been revised to include new columns for press-fit fittings used in internal and external applications.
Pressure Test Points
The latest edition includes an important clarification regarding pressure test points.
Pressure test points installed directly into the pipe wall by drilling and tapping are stated as not acceptable. The test point must instead be provided using an appropriate fitting.
Pipework in Firefighting Stairs & Shafts
The 2026 Version 12 edition includes revised guidance prohibiting the installation of gas pipework within a firefighting stair or shaft.
This is one of several updates to Chapter 6 resulting from changes to the technical guidance for installation pipework on industrial and commercial premises.
Updated Corrosion Protection Requirements
The requirements relating to corrosion protection and the application of protective tapes have also been amended.
The previous requirement for a 50% tape overlap has been increased to a 55% overlap in the new Version 12 edition.
LPG Supplied Non-Domestic Installations
Chapter 1 also contains an additional clarification relating to LPG supplied installations.
The revised guide includes information communicating the minimum requirement where a gas meter is provided for an LPG supplied installation.
