I live in a home built by property development group David Wilson that was built just over 30 years ago.
Today I decided I wanted to create a spur off a socket in my garage. Out of curiosity I decided to see which MCB it belonged to so shut off the switch labelled "downstairs sockets". This did not turn off the power to the socket. So i turned this switch back to on and switched of the MCB labelled "Upstairs sockets". Still didn't turn off the power. Turned off both MCBs and that shut off the power to the socket. This seems highly irregular. Why would a socket need two MCBs?
Do I need to get an electrician out to look at this? The plug has been providing power to my soldiering iron and workshop hoover for a decade but that still doesn't mean it's safe.
Thanks for any advice.

P.s. this socket is supplied by two wires and think each go to their respective aforementioned MCBs. See picture attached.
