CoMCoP & Gas Safe Registration


The?Consolidated Metering Codes of Practice (CoMCoP) specifies the activities involved in the management of the life cycle of the electricity and gas meter installation and maintenance – it sets out the minimum standards that shall be complied with by those registered to perform work within the scope of the CoMCoP.

The CoMCoP is a consolidation of four previous Codes of Practice in to one combined document. The CoMCoP has replaced these previous Codes of Practice:

This CoMCoP is aimed at anyone (including Independent Gas Transporter) acting as:  

  • an approved Metering Equipment Manager (MEM)
  • an approved Meter Installer (AMI)  
  • a DNO  
  • an AMR Service Provider (ASP)
  • Energy Suppliers 

For gas meter re-location, individuals must be deemed suitably competent and possess appropriate Gas Safe registration. By law all gas metering workers must be registered on the Gas Safe Register for categories relating to the work they perform. 

The temporary disconnection of a meter, and its reconnection, to allow for safe working on gas installation pipework downstream of the meter installation, is not deemed to be meter installation work within the scope of this CoMCoP. Such work is subject to the requirements of the Gas Safety (Installation and Use) Regulations (GS(I&U)Regs) See Gas Safe Bulletin TB-127 ‘Gas Industry guidance on work on meter installations’. This exclusion does not apply to the re-location of a meter installation, as this is to be considered meter installation work.  

By complying with CoMCoP and Gas Safe registration obligations, meter operators, their contractors’ and sub-contractors’ meter workers make decisions which have a significant impact on health and safety on a daily basis. A failure to meet required technical standards can be extremely serious as a failure of either electricity or gas system integrity, and any associated activities, has the potential to lead to death, injury, significant property damage and/or the loss of power and gas supplies to consumers. 

Additionally, metering equipment can be located in inconspicuous or often hidden locations, so a fault or failure of the equipment can be difficult to detect and discovery may occur sometime after the original failure to meet technical standards. Meter Operators work extremely hard to ensure the metering equipment is as safe as is reasonably practicable including with regard to the competence of meter workers.
