One appliance and crew from Gerrards Cross, two from High Wycombe and an officer attended. Firefighters used a ladder to rescue a girl from a first-floor bedroom window, and two hose reels, four sets of breathing apparatus and a fan to put out the fire.
The girl, and a woman who was out of the house when they arrived, were left in the care of South Central Ambulance Service suffering from the effects of breathing in smoke.
Firefighters also rescued two dogs and gave them oxygen.
Station Commander Paul Casey, the officer who attended the incident, said: “Very well done to all involved. I would like to say what a fantastic job both the crews and the Thames Valley Fire Control operators did of ensuring the effective rescue of the occupant trapped by smoke and fire on the first floor.
“The fire survival guidance given by the control operators, and messages passed to crews on their way to the address, enabled a swift, effective and safe rescue.”
