I'm not an expert, but it seems like you don't know enough to know what is useful and what isn't?
Additionally doing this work without notification to Building Control is a breach of Building Regulations, as a new circuit is notifiable unless you are able to self certify your work.
Still can't see why this illegal and dangerous work is required if there really is a suitably sized and functioning UPS installed.
