August 28, 2026
This is a major update to the GB-GAS Smoke and Spillage Testing app. New features include combustion performance analysis, appliance specific ratio checking, enhanced boiler testing, manufacturer data comparison, high and low fire testing, heat input recording and flue integrity testing. Positive pressure appliance spillage testing has also been added, together with an easy to use appliance reference list. The app now provides clearer test results, additional guidance when readings require further investigation and improved support for a wider range of gas appliances. Existing flue integrity and appliance spillage testing features have been retained and updated. This release significantly expands the app into a more complete combustion, flue and appliance safety testing tool for gas engineers.
