Fair Pricing
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
Charges imposed on Applicable Consumers must be fair and not disproportionate (6.1). The condition is interpreted in accordance with Ofgem's fair pricing guidance, which sets out how Ofgem will determine fairness and gives examples of the methods it may use (6.2-6.4); that guidance may be revised after consultation (6.5-6.6). Scope: this condition does not apply where the authorised person carries on regulated activities only in relation to Industrial Heat Networks or Self-Supply Networks, and where it also serves other networks the condition is construed as not applying to the Industrial or Self-Supply activities (6.7-6.8).
