Stop guessing and start calculating. GasLogicPro is built specifically for UK Gas Safe registered engineers to navigate the massive industry shift from Edition 3 to the new IGEM/UP/1B Edition 4 standards.

As of 2026, the industry has moved away from meter-based testing. Our app ensures you are fully compliant by replacing old "rule of thumb" methods with precise, volume-based calculations for both Tightness Testing and Purging.

Key Features: Smart Tightness Testing:

Step-by-step guided Let-by, Stabilisation, and Tightness tests.

Integrated countdown timers with audible alerts.

New for 2026: Automated "Installation Volume" (IV) calculations based on pipe material (Copper/Steel), diameter, and length.

IGEM/UP/1B Edition 4 Purge Calculator:

Instantly calculate Purge Volume (PV = 1.5 x IV) for any installation.

Eliminate the ambiguity of different pipe diameters and meter types.

One universal formula for Natural Gas, LPG, and LPG/Air.
