Gas and electricity meters
Any Gas or Electricity meter used for the purpose of billing, whether by a licensed energy supplier or a landlord, must be of an approved design. Most domestic and smaller industrial/commercial metering applications are covered by this requirement; therefore only meter types that operate to defined accuracy and performance requirements will be approved.
The approval of meter types was previously carried out by NMO and the Office of the Gas and Electricity Markets (i.e. www.ofgem.gov.uk ), or an equivalent EC Member State body under UK national legislation. From 30 October 2006 meters may also be approved under the European Measuring Instruments Directive (MID). The MID enables a 'European Type Approval Certificate' to be issued and the instrument can then be used in any EU Member State.
Your gas and electricity meter at home should either be approved under UK national legislation or approved under the Measuring Instruments Directive. In order to distinguish between the two, follow the relevant tabs listed on the left-hand side of this page.
