Country Fire Authority commander Gavin Hope has confirmed Wednesday night's chimney fire was in fact a false alarm.
Mr Hope said the three brigades found the smoke coming from the house to be the result of "normal chimney action".
"Two people were evacuated, but there was no fire," he said.
"It is what we call a false alarm good intent."
