A Fire and Emergency New Zealand spokesman said crews from Balclutha, Milton and Kaitangata were called to the fire in Hospital Rd at 12:45pm today.
The single-storey house was ‘‘well ablaze’’, but contained at 1.40pm, he said.
One firefighter received minor injuries at the scene and was being treated by St John ambulance.
A water tanker from Balclutha attended, along with four other fire appliances, he said.
