The fire started after a hob was accidentally turned on and ignited items which had been left on top.
A friend of the occupant and a neighbour suppressed the flames before crews arrived and ensured the fire was fully out and the smoke was cleared.
In a statement, the Jersey Fire and Rescue Service said: ‘The early suppression saved significant structural damage, however light smoke damage had affected the kitchen and adjacent rooms.
‘Although the actions [of the neighbour and friend] prevented more serious fire damage we wish to remind Islanders that we do not recommend trying to tackle fires themselves. The risk to life and health is too great. Instead follow the message GET OUT – STAY OUT – CALL 999.
‘This incident highlights the importance of fitting and testing a functioning smoke alarm. In this instance the detector fitted did not sound due to a flat battery and the occupants we alerted by the fire. Had the fire occurred later in the evening when they were asleep the outcome of this incident could have been gravely different.
‘We strongly advise never to place items on cooker tops when not in use and to maintain clear separation from the hob area and any combustible materials, to prevent accidental fires such as tonight’s.’
