Regulation 8 Method of proof and effect of meter reading
Where undertakers fix charges in relation to any premises by reference to volume, a reading from the meter installed in relation to those premises proved in accordance with this regulation shall be evidence of the volume of water supplied to those premises, unless the meter is proved to register incorrectly.
A reading from a meter may be proved by producing the certificate of a person duly authorised by the undertakers to read the meter and certify the reading.
A meter shall be regarded as registering incorrectly if on being tested it is found to exceed the prescribed limits of error.
Except where it is proved to have begun to register incorrectly on some later date, a meter which is found to exceed the prescribed limits of error shall be deemed to have done so since the last occasion but one on which the undertakers or any person duly authorised by them last read the meter for the purpose of ascertaining the volume of water supplied to the premises in relation to which it is installed.
