  • Export Meter - An export meter is only required for larger installations (greater than 30kw), the meter will measure the amount of electricity your installation exports back to the national grid.
  • Energy Performance Certificate (EPC) - Energy Performance Certificates are provided by accredited energy assessors, and are used to confirm how energy efficient your home/business is. They also provide information on how your property can improve energy efficiency and so reduce carbon emissions.
  • EPC Exemption Letter - An EPC Exemption Letter is provided by an accredited energy assessor, where the assessor finds that your property cannot be assessed for an EPC Certificate.

  • Kilowatt (Kw) - One thousand watts.


  • Megawatt (MW) - One thousand kilowatts.
  • Micro Combined Heat and Power unit (mCHP) - A micro combined heat and power unit heats the building just like a gas boiler would and also generates electricity, most of the electricity generated is used within the building.
  • Microgeneration - The production of heat/electricity generated from a low carbon source.
  • Microgeneration Certification Scheme (MCS) - The Microgeneration Certification Scheme is an independent scheme which has been setup to provide accreditation for generating units with an installed capacity of 50kw or less.


  • OFGEM - Ofgem regulate the Electricity and Gas markets in the United Kingdom. Ofgem are responsible for administering the FIT scheme.
  • Off-Grid - An installation which is connected to a private wire network and not the Electricity Network.


  • Renewables Obligation Certificate (ROC) - An existing scheme set up by the Government that rewards generators who have an installed capacity of over 50Kw.
  • ROO-FIT Process - The process that FIT generators with a capacity of over 50kW must go through in order to gain accreditation to be eligible for FIT or the Renewable Obligation.
  • Retrofit - A system installed on an existing building, as opposed to a new build.


  • Solar PV / Solar photovoltaic - Panels that produce electricity from daylight.
  • Statement of FIT Terms - The FIT agreement that FIT generators enter into with their chosen FIT Licensee.


  • Voluntary FIT Suppliers - Smaller electricity suppliers with fewer than 50,000 customers are not obliged to supply FIT to their customers. If you are supplied by a Voluntary FIT Supplier but wish ScottishPower to be your FIT Licensee, if you are eligible, we can sign you up.
