Sections20

Domestic Gas and Electricity (Tariff Cap) Act 2018

2018 c. 21

An Act to make provision for the imposition of a cap on rates charged to domestic customers for the supply of gas and electricity; and for connected purposes.

Enacted[19th July 2018]
Be it enacted by the Queen's most Excellent Majesty, by and with the advice and consent of the Lords Spiritual and Temporal, and Commons, in this present Parliament assembled, and by the authority of the same, as follows:—

The cap

1 Cap on standard variable and default rates

1 As soon as practicable after this Act is passed, the Gas and Electricity Markets Authority (“the Authority”) must modify the standard supply licence conditions so that they include conditions (“tariff cap conditions”) that impose a cap on all standard variable and default rates that may be charged by the holders of supply licences for the supply of gas or electricity under domestic supply contracts.But this is subject to section 3 (exemptions from the cap).
2 The Authority—
a may modify the tariff cap conditions from time to time, but
b must secure that such conditions continue to be included in the standard supply licence conditions until they cease to have effect by virtue of section 8.
3 The “standard supply licence conditions” are the standard conditions incorporated in supply licences by virtue of section 8 of the Gas Act 1986 or section 8A of the Electricity Act 1989.
3A If tariff cap conditions cease to have effect by virtue of section 8 in the case of supply licences for the supply of gas but continue to have effect in the case of supply licences for the supply of electricity, or vice versa, the reference in subsection (2)(b) to the standard supply licence conditions is to be construed accordingly.
4 In relation to a domestic supply contract—
a “standard variable rate” means a rate or amount charged for, or in relation to, the supply of gas or electricity under the contract that is not fixed for a period specified in the contract, and
b “default rate” means a rate or amount charged for, or in relation to, the supply of gas or electricity under the contract that applies if the customer under the contract fails to choose an alternative rate.
5 Modifications made by the Authority under this section may include consequential, incidental, supplemental and transitional modifications of the standard supply licence conditions.
6 The Authority must exercise its functions under this section with a view to protecting existing and future domestic customers who pay standard variable and default rates, and in so doing it must have regard to the following matters—
a the need to create incentives for holders of supply licences to improve their efficiency;
b the need to set the cap at a level that enables holders of supply licences to compete effectively for domestic supply contracts;
c the need to maintain incentives for domestic customers to switch to different domestic supply contracts;
d the need to ensure that holders of supply licences who operate efficiently are able to finance activities authorised by the licence;
e the need to set the cap at a level that takes account of the impact of the cap on public spending.
6A In performing the duty under subsection (6)(e), the Authority must have regard to any information provided to it by the Secretary of State, or any guidance given by the Secretary of State, in relation to the matter mentioned in that provision.
7 Nothing in this section is to be read as requiring the cap imposed on a standard variable or default rate to apply in relation to any charge that—
a forms part of that rate, but
b is not paid on a regular basis by the majority of customers who pay that rate.

2 Tariff cap conditions

1 Tariff cap conditions—
a have effect in relation to supply licences, whenever granted, and domestic supply contracts, whenever entered into;
b must set out how the cap is to be calculated, and may make provision about assumptions required to be made in making the calculation;
c may make provision specifying how a standard variable or default rate is to be identified;
d may make provision requiring information to be provided by holders of supply licences to the Authority for the purposes of exercising functions relating to tariff cap conditions;
e may confer functions on the Authority;
f may make different provision for different areas or different cases;
g may do any of the things authorised for supply licences by section 7B(5)(a), (6) or (7) of the Gas Act 1986 or section 7(3), (4), (5) or (6A) of the Electricity Act 1989.
2 But tariff cap conditions may not—
a exempt holders of supply licences from their application, or
b make different provision for different holders of supply licences.
3 Before making the first modifications under section 1 the Authority must, and before making any subsequent modifications under that section the Authority may, consult such persons as it considers appropriate on the methodology to be used for the purposes of the cap.
4 Consultation undertaken before this Act is passed is as effective for the purposes of subsection (3) as consultation undertaken after it is passed.

3 Exemptions from the cap

1 Tariff cap conditions do not apply in relation to domestic customers who—
a benefit from the cap on rates or amounts charged for, or in relation to, the supply of gas or electricity provided for by the Energy Market Investigation (Prepayment Charge Restriction) Order 2016, made by the Competition and Markets Authority, or
b benefit from a cap on such rates or amounts that is a replacement for the cap provided for by that Order.
2 Tariff cap conditions may provide for the conditions not to apply in relation to—
a domestic customers who benefit from a cap imposed by the Authority on rates or amounts charged for, or in relation to, the supply of gas or electricity to customers who appear to the Authority to be vulnerable by reason of their financial or other circumstances;
b standard variable rates which apply only if chosen by domestic customers if, or to the extent that, the rates in question appear to the Authority to support the production of gas, or the generation of electricity, from renewable sources.
3 The Authority must consult such persons as it considers appropriate about whether and, if so, how to exercise the power conferred by subsection (2)(b).
4 The Authority may carry out the consultation either before, or in the course of, taking the steps described in section 4 in relation to proposed modifications which consist of or include provision to be made in the exercise of the power conferred by subsection (2)(b).
5 The Authority must secure that the consultation is carried out at a time that will enable it, if it decides to exercise the power conferred by subsection (2)(b), to do so—
a when making the first modifications under section 1, or
b if that is not practicable, as soon as practicable after it has made the first modifications under that section.
6 Consultation undertaken before this Act is passed is as effective for the purposes of subsection (3) as consultation undertaken after it is passed.

Protection for customers after termination

9 Protection for domestic customers after termination of tariff cap conditions

1 The Authority must, at such intervals as it considers appropriate, carry out a review into—
a the pricing practices of holders of supply licences for the supply of gas and electricity under domestic supply contracts, and
b whether there are categories of domestic customers paying, or who may in the future pay, standard variable and default rates for whom protection against excessive charges should be provided.
2 Such a review must, among other things, consider—
a whether there are domestic customers who the Authority considers will suffer an excessive tariff differential where on the termination of fixed rates the customers move to standard variable or default rates, and
b whether customers who appear to the Authority to be vulnerable by reason of their financial or other circumstances are in need of protection.
3 If the review concludes that protection should be provided, the Authority must take such steps as it considers appropriate by the exercise of its functions under the Gas Act 1986 and the Electricity Act 1989.
