Energy Operators (Powers) Act 1979

The extent, characteristics, and value of the energy supplied by an energy operator to any premises, or any part of any premises separately so supplied, shall, unless otherwise agreed by the energy operator or some other provision of this Act applies, be ascertained by reference to an appropriate meter fixed and connected to the supply system in a manner approved by the energy operator.

In relation to any supply or proposed supply of energy by an energy operator to any premises, or to any part of any premises separately so supplied, the energy operator may —

cause a meter to be placed so as to serve the premises, or that part of those premises, for the purpose of ascertaining the extent, characteristics, or value of the supply;

cause a meter or other device, which may be additional to any meter placed for the purpose of ascertaining the extent, characteristics, or value of the supply, to be placed so as to serve the premises for the purpose of regulating the supply, or the period of supply or the nature or extent of the supply;

at all reasonable times without prior notice by any officer or servant of the energy operator enter upon the premises in so far as is necessary and there execute all works and do all acts needed to inspect, read, examine, test, maintain, and repair any meter or any apparatus, works, or device belonging to the energy operator, and remove or replace the same.

An energy operator may make a charge in respect of the costs of installing, maintaining, removing or replacing a meter placed to ascertain the extent, characteristics, or value of the supply effected by the energy operator.

An energy operator may, on payment of such charges, and on such terms and conditions, as may be prescribed or as are otherwise agreed, supply a meter for purposes other than ascertaining the extent, characteristics, or value of the supply effected by the energy operator, but in any such case, except where the contract relating to the supply of that meter otherwise provides, the energy operator shall not be liable for or in respect of any loss or damage occasioned to the person to whom such a meter is supplied whether by reason of the reliance of that person on the proper functioning of that meter in his dealings with any other party or otherwise.
