A Passer-by who saw Surrey Towers on fire tried to get into the flat to help people.
The man, in his 40s, who does not live in the high-rise block on Garfield Road, Addlestone, was one of the first people to alert fire crews of the blaze on Saturday morning.
He was one of two people taken to hospital and was treated for smoke inhalation.
An elderly woman, thought to be in her 90s, who lives on one of the floors above the flat, was treated for smoke inhalation and shock.
Fire investigating officer Derrick Chegwin said the man had tried to get into the flat, which was unoccupied at the time of the fire.
"I arrived here as the investigating officer and the fire was out," Mr Chegwin said.
"By the time I got there people evacuated as they should. It was quite ordered."
The fire broke out in a fourth floor flat after a cigarette had not been stubbed out properly. It spread from the balcony to the property next door.
Around 40 firefighters fought the blaze, which has been recorded as accidental.
