This form is required for a customer or FIT licensee wishing to have a certificate amended where the original installer has ceased trading or is no longer MCS certified.
Please note: An MCS certificate should never be updated unless the installation details were incorrectly recorded at the time of the system’s first commissioning. Changes to an installation that occur after the original system commissioning do not need to be notified except where the output of the system is now greater. If this is the case a new certificate will need to be generated. We advise you speak to your energy supplier (FIT) or OFGEM (RHI) for clarity on how this may affect any incentive you receive before proceeding with any amendments to the system.
