I am in the UK.
I wish to install a socket (possibly a double) in the under stair area of my house. The main consumer unit is based here and also the alarm box. One option would be to get an electrician to put in either a separate circuit (overkill) or split the downstairs ring at the consumer unit to provide a socket there, but I'd like to avoid that if possible.
The other potential option is that the alarm is run off a fused spur. Is it acceptable/legal to run a socket off this fused spur? If so, should it be that I run it between the fused connection unit and the alarm or can I run two cables out of the FCU (basically in parallel)?
