Hi, I live in a house that has been converted into three flats. Each flat has a circuit breaker box, but there doesn't appear to be one for the communal lights. We have an issue with the communal lights being permanently on (because of a faulty timer switch). Is it normal for there to be no circuit breaker for it? Any idea how we're supposed to repair the lights? (There also doesn't appear to be an overall electricity switch for the property, just the circuit breakers for each flat).
