1
A supplier must not, in respect of energy supplied under a supply contract, unreasonably—
a
increase the rates at which it charges any amounts payable by the customer under the supply contract,
b
expose a customer to any additional risk, or
c
change any of the following so they are less favourable to the customer—
i
the terms of the supply contract;
ii
the terms on which the supplier offers to enter into supply contracts;
iii
the process by which prices or charges payable under supply contracts are set;
iv
the way in which the supplier exercises its rights under its supply contracts.
2
For the purposes of determining whether a supplier has behaved unreasonably in doing any of the things referred to in paragraph (1)(a) to (c)—
a
a supplier’s conduct is, in particular, unreasonable if, and to the extent that, the conduct, or the supplier’s ability to retain the customer as a customer while engaging in it, is facilitated by the existence or operation of the scheme;
b
it is, in particular, reasonable for a supplier to increase its charges—
i
to its customers collectively, by an amount that in aggregate does not exceed the efficiently incurred costs of complying with these Regulations;
ii
to any customer, by an amount that does not exceed its fair and reasonable share of such efficiently incurred costs.
