The government accepts this recommendation in principle. We agree with the Inquiry's findings that accessibility and functionality of such valves is key to ensuring health and safety by stopping gas supplies in an emergency. Whilst inspections every three years may be appropriate, there may be other situations where inspections should be more frequent or where a longer interval is suitable. To inform this, the Health and Safety Executive (HSE) is engaging with key stakeholders to fully map out and understand current system integrity approaches, noting changes to operator's arrangements since the Grenfell tragedy, and the interrelationships between gas network operators, building owners, accountable persons and landowners to understand the challenges encountered when issues with pipeline isolation valves are identified and routes to resolution. Using this evidential research, HSE will develop initial options by March 2025, with a proposed timetable for taking forward a preferred option.
