Safe Control of Operations (GB)


About the Scheme

Safe Control of Operations (GB) – SCO (GB) – provides a framework to support safe and legally compliant working practices on gas networks in both routine (RO) and non-routine operations (NRO). This scheme enables individuals employed by the gas distribution networks to become a named Competent Person (CP) or an Authorising Engineer (AE) for both Permits to Work and Forms of Authority, depending on their role in their employing organisation.

The SCO (GB) registration categories are as follows:

  • SCO 1 & 2: Competent Persons (RO) Team Leader
  • SCO 1 & 2: Authorising Engineers and Competent Persons (NRO Supervisory level)
  • SCO 4: Authorising Engineers and Competent Persons (NRO)
  • SCO 4 & 5: Authorising Engineers and Competent Persons (NRO)
  • SCO 5: Authorising Engineers and Competent Persons (RO)

The employing organisation’s Responsible Engineers decides the individual role (e.g. Authorising Engineer) and work type (e.g. Network >2bar -7bar) is correctly identified. For example, an individual may have a role as an Authorising Engineer for Permits to Work and Routine Operations but limited to Competent Person for Non Routine Operations, in which case they would be expected to complete SCO 1 & 2 Authorising Engineers and Competent Persons plus SCO 4 & 5 AEs and CPs.


Registration on EUSR

Each registration category for SCO (GB) registration is valid for 5 years. For re-registration on EUSR, individuals must be re-assessed to ensure that they have maintained their specific knowledge in areas such as “Permits to Work” as well as kept up-to-date on underpinning knowledge in areas such as new policy and legislation. Evidence is required for verification by EUSR that the individual has completed the relevant training and assessment for the registration category.

The reassessment method varies dependent upon which network is being worked on. Please contact the appropriate Network Controller for futher information.

SCO (GB) registration does not confirm competence to carry out a task or particular role. It is designed to provide evidence that an individual has attended the relevant training course and demonstrated an appropriate level of knowledge and awareness.

Given the complex nature of SCO (GB), the full range of information cannot be detailed on the EUSR card – the need to check with the network controller is included within the detail on the card.
