(c)the voltage,
at which it proposes to deliver the supply and the extent of the permitted variations of those values:

(2) For the purposes of this regulation, and unless otherwise agreed by the consumer, the permitted variations are—
(a)a variation not exceeding one per cent above or below the declared frequency; and
(b)a variation not exceeding six per cent above or below the declared voltage at that frequency where that voltage is below 132 kV, and not exceeding 10 per cent above or below the declared voltage where that voltage is 132 kV or above,
or the variation which may have been authorised by the Secretary of State under paragraph (3).
(3) The Secretary of State may, on application by a supplier, authorise him to alter any of the declared values or any permitted variation if he gives such notice of his application as the Secretary of State may require.
(4) The supplier shall forthwith give notice of any authorisation under paragraph (3) to every consumer to whose supply it may apply.
(5) The supplier shall ensure that, save in exceptional circumstances, any supply he gives complies with the declaration under paragraph (1).
(6) The polarity of direct current and the number and rotation of phases in any supply shall not be varied without the agreement of the consumer or, in the absence of such agreement, the consent of the Secretary of State who may impose such conditions, if any, as he thinks appropriate.
