Connection Market Segments

New and augmented connections are categorised for regulatory reporting purposes and are also referred to in other publications, such as the Incentive for Connections Engagement (ICE).

Connections schemes are grouped into market segments which are determined by the type and the highest voltage of works required to provide a connection scheme.

  • Demand Connections

    In respect of Metered premises owned or occupied by Demand Customers:

    (i) LV work: low voltage Connection Activities involving only low voltage work, other than in respect of Excluded Market Segments;

    (ii) HV work: low voltage or high voltage Connection Activities involving high voltage work (including where that work is required in respect of Connection Activities within an Excluded Market Segment);

    (iii) HV and EHV work: low voltage or high voltage Connection Activities involving extra high voltage work;

    (iv) EHV work and above: extra high voltage and 132kV Connection Activities.

    Distributed Generation

    In respect of Metered premises in which Distributed Generation is situated:

    (v) LV work: low voltage Connection Activities involving only low voltage work;

    (vi) HV and EHV work: any Connection Activities involving work at high voltage or above.

    Unmetered Connections

    In respect of unmetered premises:

    (vii) LA work: New Connection Activities in respect of local authority premises.

    (viii) PFI work: New Connection Activities under private finance initiatives.

    (ix) Other work: all other non-local authority and non-PFI unmetered connections work.

  • Often referred to as large connection customer schemes, these are subject to regulated or unregulated margins according to our charging methodology. These market segments are within the scope of our Incentive for Connections Engagement (ICE).

  • Small Connection projects are classified as excluded market segments, which are not subject to regulated/unregulated margins and are not within the scope of ICE. We do often ensure to deliver improvements for all connection customers even where they are not within a Relevant Market Segment. These excluded market segments, however, remain within the scope of the broad measure customer satisfaction incentive and time to connect incentive in the RIIO ED1 (Revenue Incentives Innovation Output Electric Distribution 1) Price control.

    The combination of the following two segments relating to Metered premises that are owned or occupied by Demand Customers and are defined by reference to the nature and volume of the Connection Activities:

    (i) Domestic LV work: low voltage Connection Activities relating to no more than four Domestic Premises;

    (ii) One-off industrial and commercial work: Connection Activities in respect of a connection involving three-phase whole current metering at premises other than Domestic Premises.
