As a result of the accident Daniel was left with burns on his face, chin, neck, left arm, chest and back. The burns caused a large blister on his arms and blisters on his chin.
Last week Daniel was reunited with Ms Bennison and Mr Fraser, after sending a thank you painting to them for their efforts.
Mr de Jager said he and his wife appreciated the efficiency of St John. "They were in charge and I knew we were in good hands."
A year later, although Daniel had no visible scars, Mr de Jager said he and his wife were now "vigilant" with appliances and hot objects in the kitchen.
"Continue to make sure the kitchen is child proofed Be aware of how quickly a situation can change and if things are bad make sure you call 111," Mr de Jager said.
