We have a technical information website specifically to provide detailed technical specifications and policy documents for connection providers working within our four licensed areas.
In addition, a suite of Ofgem national framework documents have been developed setting out common requirements for design and planning, material specification and installation and records. These are supplemented by local WPD appendices which must be read in conjunction with the national framework documents.

A connection provider may provide diversionary or reinforcement work that is directly associated with a new or augmented connection at voltage levels not exceeding 33 kV. The scope of such work is set out within a further national framework document. Please click on the link below.
NGED have a published set of Distribution Safety Rules (DSR's) which are in place for the protection of employees and the safety of all who may work on distribution network operator systems.
