Registration
Every authorised person. Section A applies to everyone holding a heat network authorisation, whether they operate the network, supply heat over it, or both.
What this condition requires
Before the end of the first part of the initial period (26 January 2027, per regulation 26(1)), inform Ofgem of each regulated activity carried on and provide the information required by its registration arrangements (4.1). Required information covers: the nature of the activities and any contractual arrangements relating to them; the relevant heat network(s); the authorised person itself and any other authorised persons at those networks; financial status, ownership and organisational structure; the consumers supplied, their relevant characteristics and billing arrangements; and matters relevant to compliance (4.1.2). Where supply and operation are carried on by different entities, registration is sequenced: the supplier must co-operate with the operator and provide it with relevant information, and the supplier's own obligation does not arise until at least one operator has discharged its obligation (4.2). Where a network has multiple operators, 4.3 applies. Registration is per network and generates its own confirmation and unique ID.

4.2 Where the authorised person carries on the regulated activity of supply by means of a relevant heat network but does not also operate that relevant heat network:
4.2.1 the authorised person must co-operate with the operator(s) of the relevant heat network, including by providing relevant information to the operator(s), to facilitate the timely discharge by the operator(s) of their obligation(s) under paragraph 4.1; and

4.3 Where:
4.3.1 in accordance with regulation 13(4)(b) of the Regulations, the authorised person and one or more other authorised persons each operates a relevant part of a relevant heat network;
4.3.2 the authorised person has agreed with one such other authorised person that such other authorised person will submit the information required by paragraph 4.1 in relation to each of them and the relevant heat network; and
4.3.3 such other authorised person submits such information,
the authorised person will be taken to have complied with its obligation in paragraph 4.1 in relation to that relevant heat network.
