General RHI Eligibility Requirements

1. The owner of the installation must be the applicant. Where located on third party premises, the participant will be required to ensure access for OFGEM inspections.

2. Installation capacity will be the peak heat output capacity of the installation, information on which is available from the equipment's distributor or manufacturer.

3. An installation is "plant" which meets the eligibility criteria.

4. OFGEM's interpretation of associated infrastructure and integral equipment;

Associated infrastructure - all heating installations;

• Heat (hot water/ liquid and steam) meters
• Heat distribution system (e.g. pipes delivering heat to users, heating controls, pumps, valves, radiators/ heat distribution and heat exchangers etc.)
• Heat storage equipment
• Other buildings housing the plant equipment (e.g. boiler house) & foundations

Integral equipment - solid biomass plants;

• Boiler (e.g. ignition equipment, heat exchanger, electrical wiring and controls, combustion chamber, grate, air control, housing/ container)
• Pipework required for the effective start up and shut down of the plant (e.g. back end loop/ valve)
• Fuel feed equipment (e.g. auger, moving floor etc) where these are likely to be integral to the operation of the plant
• Flue gas treatment equipment (where it is different to the equipment required for a comparable gas installation) & fuel storage equipment (e.g. fuel hopper)

Solid biomass associated infrastructure;

• Ancillary fossil fuel equipment (e.g. gas start-up equipment)
• Fuel delivery, processing (e.g. chipping/ drying) and preparation equipment
• Fuel store housing (e.g. fuel storage sheds, bunkers) & flue

5. No Other Grants; RHI support will only be available for an eligible installation if no grant from public funds has been paid or will be paid.

6. Plants are only suitable for accreditation if their installation was completed and first commissioned on or after 15 July 2009.

7. Your plant must be new, have not been previously used or relocated. RHI Guidance Document Summaries 05/03/2012 Page 5 of 17

8. Installations heating one single domestic premises are ineligible, but district and community heating is eligible.

9. Heat delivery medium; the installation must use liquid or steam as a medium to deliver heat.

10. Microgeneration requirements; biomass installations of 45kWth or less will be required to be backed up with certification under the Microgeneration Certification Scheme (MCS).

11. Other requirements, district heating; such as a central boiler for an apartment building, or a network of pipes delivering heat from a central installation to a number of local households or businesses - will be eligible for the RHI where the heat is produced by an eligible installation. District heating will be treated in the same way as any other RHI installation and there is no uplift for district heating installations. For example, a district heating system served by a 600kWth biomass boiler will be treated the same way as a 600kWth boiler heating a single building in terms of RHI eligibility and support levels. District heating, where more than one building is being served, will be subject to the 'complex' metering requirements as described in Chapter Seven.
