A panel heater not working usually means no heat from a wall-mounted or freestanding unit even when the room feels cold and the rest of the flat still has power. In UK flats and rentals that often shows up as a dead fused spur, a blown plug fuse on a freestanding heater, a thermostat that never calls for heat, or a thermal cutout that has tripped because dust blocked the air intake. Picture a rented bedroom in late September: the wall panel stays cold overnight, the tenant checks the spur neon is off, and nobody wants to open a hardwired heater with the supply still live. Confirm power at the spur or socket, check the thermostat and timer, clear blocked vents, and stop if you smell burning or see scorch marks - that is when you book an electrician.
