This guidance is relevant for both MCS-FIT and ROO-FIT accredited installations. It provides an overview of the FIT scheme, detailing the scheme guidelines, and explains the steps generators should take when modifying an accredited FIT installation.
Version 18 has been redesigned to improve readability and accessibility, with a new title that better reflects its focus. Several chapters have been reduced by removing outdated information following the closure of the FIT scheme. There have also been updates and additions to several sections, including guidance on generator ownership checks, co-locating installations with batteries and EV charging points, and the interactions between the FIT and SEG schemes.
