The voice of the networks

How can this website be improved? Give us your feedback


We collect and manage information related to energy network operations and hold this in various databases, accessible publicly or to our members.

Some of the information we hold is statutory, other work includes collating safety statistics, cataloguing engineering standards and terms. This is streamlined through a number of databases (sometimes known as ‘portals’) which facilitate information exchanges across those involved or interested in the industry.

Other documentation can be found in our Resource library.

  • Competition in Connections Code of Practice (CiC COP)

    The Competition in Connections (CiC) Code of Practice governs the way in which Distribution Network Operators (DNOs) provide input services to facilitate competition in the electricity connections distribution market. It will help customers have more choice over their connection provider.

  • DCode website

    Licensed electricity distribution businesses, or Distribution Network Operators (DNOs) in Great Britain, are obliged under Condition 21 of their licences to maintain a Distribution Code detailing the technical parameters and considerations relating to connection to, and use of, their electrical networks.

  • ENA accident database

    Reporting of accidents through the ENA accident database.

  • Engineering document catalogue

    The Document Catalogue System is an online catalogue of engineering documents available from ENA. Documents available from the site include technical specifications, engineering recommendations and reports, BEBS specifications and reports supporting the electricity network process and policies.

  • National Equipment Defect Reporting Scheme (NEDeRS)

    NEDeRS is an industry database used to record and communicate defects on electricity plant and equipment to support the safe operation of the networks.

  • National Gas Incident Site (NGIS)

    NGIS is an industry database used to record incidents on the gas network to support the safe operation of the networks.

  • Network Innovation Collaboration (NIC) Portal

    A collection of opportunities across the energy networks to collaborate on innovation, including our annual joint NIC Call for Ideas.

  • Smarter Networks Portal

    The Smarter Networks Portal provides an overview of the technical and commercial coverage of current smart grid projects in GB. 

  • Type Test Verification Report Register

    The register holds certificate and test documentation for products related to small scale electricity generation in the UK market including PV panels, wind turbines etc, that were connected to DNO networks before 27 April 2019.

  • Security Incident Reporting System (SIRS)

    The Security Task Group (STG) is concerned with all aspects of security on the electricity network. Theft, in particular, has become an increasing problem in recent years largely due to the steep rise in the cost of commodities such as copper and steel. The reporting system can be accessed by users assigned by STG

  • Embedded capacity registers

    The development of Embedded Capacity Registers (ECR) by network companies provide better, standardised information to customers and stakeholders on connected resources and services. The links below will take you to the ECRs that have been developed by each network operator.

    The Embedded Capacity Registers were initially developed and known System Wide Resource Registers (SWRR).

  • Heat pump database

    database of common heat pumps has been created to support the application process.

    Please note that air-conditioning units are considered a form of heat pump, and hence the same process applies.

    In addition to the other requirements detailed in the flowchart, an installer should use the heat pump database to cross-reference their device(s) to assist in determining whether they can ‘Connect & Notify’ to the network operator or ‘Apply to Connect’.

    The corresponding columns relate to Power Quality (PQ) aspects only. It is necessary to refer to the flowchart and form for the full process.

    The only Heat Pump information that will be made publicly available is on the first tab of the spreadsheet ‘A1_Summary’. We welcome installers and manufacturers who have devices that are not in the database to populate the information in the other (template) tabs, which will not be made publicly available, and send it to us for verification.

    One Heat Pump model shall be submitted per spreadsheet. Data shall be submitted electronically by email using a copy of one of two template spreadsheets:

    Attach any accompanying supporting information to the email and send to [email protected].

    A set of guidance notes explain how to submit the HP data.

  • Energy Data Request Tool

    The Energy Data Request Tool can be used by anyone to request any type of network data. Requests are processed using Microsoft Forms and managed in line with our privacy policy. Learn more about Microsoft’s privacy practices.

    The Energy Data Request Tool will help gather insight into the volume of requests, their origin, the granularity of data requested and how the data will be used. In creating a single point for data requests and standardising networks’ approach to servicing these requests, we will ensure data from across the networks is “Discoverable, Searchable, Understandable”.
