Main information
What it could mean
A loose connection can cause anything from flickering and intermittent cuts to localised heat, depending on where it is.
Safety first
Don't try tightening connections yourself inside junction boxes, sockets, or the switchboard; the fitting may be live.
Next step
Locating a loose connection requires checking the affected circuit point by point until the exact source is found.
