In regulation 3(1) (interpretation), in the definition of “British Standard Requirements”, everything after the words “BS 7671: 1992,” shall be deleted and there shall be inserted the words “as amended by Amendment No. 1, 1994 (AMD 8536) and published by the Institution of Electrical Engineers in 1994 in London (ISBN 0 85296 839 6, 1994);”.
4 
In paragraph (1) of regulation 30 (declaration of phases, frequency and voltage at supply terminals) for the words “240 volts” there shall be substituted the words “230 volts”.
5 
For paragraph (2) of that regulation there shall be substituted the following paragraph—“
(2) For the purposes of this regulation, unless otherwise agreed by the consumer, the permitted variations are:
(a) a variation not exceeding one per cent above or below the declared frequency;
(b) in the case of a low voltage supply, a variation not exceeding ten per cent above or six per cent below the declared voltage at the declared frequency;
(c) in the case of a high voltage supply operating at a voltage below 132 kV, a variation not exceeding six per cent above or below the declared voltage at the declared frequency; and
(d) in the case of a high voltage supply operating at a voltage of 132 kV or above, a variation not exceeding ten per cent above or below the declared voltage at the declared frequency.”

After paragraph (5) of that regulation there shall be inserted the following paragraph—“
(5A) For the purposes of paragraph (5), any declaration under paragraph (1) made before 1 January 1995 in respect of a low voltage supply shall have effect as if—
(a) the declared voltage, unless otherwise agreed between the supplier and the consumer, was 230 volts between the phase and neutral conductors at the supply terminals; and
(b) the permitted variation of that value, unless otherwise agreed between the supplier and the consumer, was a variation not exceeding ten per cent above or six per cent below that declared voltage at the declared frequency.”
