The voice of the networks

Standards and guidance

We are responsible for producing and maintaining a range of industry standards and guidance.

Engineering standards and guidance

We develop and maintain the engineering standards used by the network operators to support the management of a safe and reliable electricity network. All engineering standards and guidance documents can be found on the ENA Engineering Document Catalogue.

ENA documents and specifications are drafted to assist our members in complying with relevant statutory obligations as set out in their Licence Conditions, and in the Distribution Code and its supporting documents.

Documents produced by us are developed using input from a combination of experts within our membership, the use of specialist external consultants, relevant UK and GB Trade Associations and industry bodies, manufacturers, suppliers, and users of the documents.

Our documents primarily consist of:

  • Technical Specifications (TS) typically based off International (IEC) and British and European (BS EN) standards with additional UK and GB requirements and;
  • Engineering Recommendations (EREC) and Reports (ETR & EREP) typically focused on best practice or guidance information, however application of EREC documents that support Distribution Code compliance is mandatory.

Electricity Standards of Performance

ENA members have developed three guides to the standards for suppliers and customers, including how to contact your distribution network operator in the event of a query or claim:

  • Metered Connections Guaranteed Standards of Service for Electricity Distribution Companies in England, Wales & Scotland (May 2020)
  • Unmetered Connections Standards of Service for Electricity Distribution Companies in England, Wales & Scotland (May 2020)
  • Guaranteed Standards of Performance for Metered Demand Customers of Electricity Distribution Companies in England, Wales & Scotland (May 2020)

 

Gas Industry Standards

Gas Industry Standards (GIS) are product specifications for gas carrying assets and some specialist tooling used by the gas networks (GNs) in the UK. They are jointly owned and maintained by National Grid, Cadent, SGN, Northern Gas Networks, Wales & West Utilities and Gas Networks Ireland under the governance of the Technical Standards Forum (TSF).

The Purpose of Gas Industry Standards

A common objective for GNs is to use product specifications that are consistent across the industry. This is to prevent divergence of standards which would lead to additional complexity and cost in manufacturing, and to confusion in the market place. Additionally, the use of a single product conformance certification process reduces duplication of effort for product approval.

  • Product approval

    Where a GIS applies to a product used to contain gas in the distribution system, then that product requires Kitemark certification from the British Standards Institution (BSI). This provides independent verification that the product conforms to the required standard.

    For some non-gas carrying products and certain low volume gas carrying products then verification certification provides an alternative approvals process.
