Northamptonshire Fire and Rescue was called shortly before 3pm on February 2 to reports of a 2 storey, semi-detached thatched property on fire in the village of Grafton Underwood.
Crews in breathing apparatus used hose reel jets to tackle the blaze, which quickly spread to 4 properties.
National Grid were in attendance who isolated power to all affected properties.
The fire was put out shortly after 11pm, however crews have remained at the scene throughout the night and following day to monitor hotspots and continue dampening down.
Eleven fire appliances attended, including the aerial pump and a drone team from Warwickshire Fire and Rescue Service, with approximately 50 firefighters attending throughout the incident.
Our staff, including those in our control room, worked hard to manage the incident but also to ensure the rest of the county had adequate cover while the incident was dealt with.
Northamptonshire Fire and Rescue Service would also like to thank residents of the village for their support and patience throughout this incident, which has caused significant disruption to the area. Their assistance has included helping to look after the welfare of our crews at the scene by providing food and drinks and making facilities available for them to use.
A fire investigation to determine the cause is due to take place, once it is safe to do so.
