Response — verbatim from government
●Health and Safety Executive
The Government accepts this recommendation. We must have sufficient knowledge about the replacement material to be confident that a similar situation will not arise again. HSE will review the natural gas programme and identify any possible gaps. If additional research work is needed to ensure the results can be applied to LPG then this will be taken forward by HSE. HSE to consult with IGEM, UKLPG and PE pipe manufacturers on appropriate integrity tests. (Cm. 7849, paras 39-42)

- 31 Dec 2015 Implementation confirmed by HSE. All buried metallic LPG service pipe replacements completed by 2015 deadline. Source →
- 18 Mar 2010 HSE reviewed natural gas pipeline replacement research on polyethylene pipe long-term stability. Findings indicated PE pipes have long-term stability (50-year design life, potentially extendable). HSE consulted with IGEM, UKLPG and PE pipe manufacturers on integrity tests. Source →
- 31 Dec 2015 · Health and Safety Executive HSE funded research into polyethylene piping safety and published guidance for domestic LPG customers. HSE went beyond the Gill recommendation in providing advice for domestic premises. View source → Confirmed Completed

How this page is built
Source and Response are verbatim from primary documents. The Evidence trail records published activity since — written statements, consultation outcomes, inspection findings, parliamentary references. The Index does not paraphrase or characterise intent; it tracks what has been published. Where the evidence is the absence of action (a missed deadline, a slipped timetable), that absence is documented from primary sources rather than inferred.
This recommendation's data is verified periodically against primary sources. The Index is monitored for staleness weekly.
