My whole flat lost power but the neighbours are fine. Who do I call?
the desk replies — First check your own DB: if the main isolator or RCD has dropped, reset it once. If the board is fully on but the flat is dead, the fault is likely at the meter or the building's riser, which is the utility's or building management's side. Call the building's maintenance desk or the utility's fault line; a private electrician cannot legally open that part of the installation.
