In Depth Electricity meters for Feed-In Tariffs (also known as FITs) are part of a Government backed scheme that pays people for generating their own "green electricity" (i.e. photovoltaic, wind, or hydro). The scheme is administered by Ofgem on behalf of the Department for Energy and Climate Change and further information is available from: http://www.ofgem.gov.uk/sustainability/environment/fits/Pages/fits.aspx To apply for the FIT scheme, installations must be in Great Britain and have a meter compliant with the metering legislation in place. This means that the electricity meter must be of an approved pattern or construction in accordance with Schedule 7 of the Electricity Act 1989. Prior to October 2006, only an approval issued under GB national legislation would satisfy this requirement and these meters are listed on the statutory list, known as Schedule 4. Visit the scehdule 4 section of the NMO website. From 30th October 2006, “approved” may also refer to an electricity meter type approved by a notified body under the European Measuring Instruments Directive (MID 2004/22/EC). NMO is responsible for designating notified bodies in the UK for the majority of the instruments covered by the Directive and SGS (UK) Ltd have been designated as a Notified Body for the conformity assessment of active electrical energy meters under Annex MI-003. Download MID approval certificates issued by SGS (UK) Ltd on the NMO website. MID approved meters are also required to carry the MID markings as required under the Directive. These consist of the CE marking, the MID marking which is made up of the letter ‘M’ and then the year of manufacture (for example a meter manufactured in 2011 would have the following MID marking ) and a four-digit code representing the Notified Body that approved and verified the meter. - See more at: http://www.bis.gov.uk/nmo/gas-and-electricity-meters/electricity-meters-introduction/Electricity-meters-for-feed-and-tariffs#sthash.WrAsI3ar.dpuf
