Types of licence conditions

Standard Licence Conditions

Standard Licence Conditions are conditions that apply to all licensees of a particular licence type.  These can be in and out of effect for licensees.

Amended Standard Licence Conditions 

Amended Standard Licence Conditions are Standard Licence Conditions that have been modified for an individual licensee.

Special Conditions

Special Conditions are conditions that apply only to individual licensees and form part of their licence alongside Standard Licence Conditions, any amended Standard Licence Conditions, and any Standard Special Conditions that may apply to them.

Standard Special Conditions

Standard Special Conditions were created during the gas Distribution Network sales, when Transco sold off four of their distribution networks. The Standard Special Conditions apply only to Gas Transporters with distribution networks and to National Grid Gas Plc.
