- **Overloaded socket** — plugging too many high-draw appliances (like kettles, heaters, and hair dryers) into a single socket or extension lead can cause overheating.

- **Faulty appliance** — occasionally the smell originates from a plug or appliance, not the socket itself. Try removing all plugs and checking if the smell persists.
