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.

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.

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.

Following the development of System-Wide Resource Registers (SWRR) by network companies to provide better, standardised information to customers and stakeholders on connected resources and services, these registers have been renamed as Embedded Capacity Registers (ECR). This delivers a DCUSA obligation that has become effective following the approval of DCUSA change DCP 350 in July 2020. The links below will take you to the ECRs that have been developed by each network operator.

• Electricity North West
• Northern Powergrid
• SP Energy Networks
• Scottish & Southern Electricity Networks
• UK Power Networks
• Western Power Distribution
• National Grid ESO

A 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:

• Heat pump – split system
• Heat pump – whole system

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.
