The feed-in tariff for solar PV installations is linked to the EPC rating of the building or buildings in which it is installed, or through which it is wired. Unless the installation is for a community building (e.g. a school or building belonging to a charity), the system owner has to prove that any building that is wired in such a way as to benefit from the electricity produced by the PV array has an EPC rating of D or above. If they do not prove this then they will not qualify for the full feed-in tariff rate and will be locked into a FIT rate of 0.2p/kWh for life (inflation linked).
If you don’t have an EPC then the good news is that Spirit Energy includes the EPC as part of our installation.
The key wording in the government regulations is that if the solar PV system is wired “in order to provide power to a building that can have an EPC”, then this building needs to have an EPC. A “building” for this purpose is defined as a construction having a roof and walls that uses energy to control its internal climate. For example, this means that if an installation is going on an outbuilding that is unheated, but this outbuilding is wired to the same electricity meter as a house which is heated, this house will need to have an EPC rated D or above.
If you have questions about the EPC requirement, please don’t hesitate to contact us for more information.
