Signs that a rewire may be needed include old rubber or fabric-covered cables, a fusebox rather than a modern consumer unit, regularly tripping circuits, burning smells from sockets, or flickering lights. If your property is over 25-30 years old and hasn't had an electrical inspection, an EICR is a good first step. We can advise you after the inspection.
