16 may conrm that it is risk-free for the enhancement or modification to continue, relying on the certain installment and the nature of the enhancement or alteration, there might be a series of practicalities that need to be discussed with the client - A&A Works. Brand-new circuits may be needed however the existing consumer unit may have no extra means or might not be an ideal kind of system to set up an RCD or RCBO.
