An investigation will take place after a huge fire at a large agricultural building. 

Six fire engines were called to Braintree Road in Felsted at 11.56pm last night (August 29). 

On arrival, crews confirmed the building, which is single storey and measures approximately 140 metres by 15 metres, was completely alight.

Callers reported seeing smoke from the fire from the nearby A120.

Due to the remote location of the fire, the officer in charge called for the support of a water bowser, a vehicle which can carry a large amount of water to help maintain supply for crews.

At 1am, the fire was surrounded and under control, but there continued to be a large volume of smoke.

Essex Police were managing traffic on the nearby roads, and part of Braintree Road will remain closed for some time while firefighting continues.

No livestock was affected in the fire.

Incident commander Steve Wintrip said: "I'd like to thank our incredible crews for their quick response to what could easily have been a much more challenging incident.

"The speed they managed to get this fire surrounded is testament to their professionalism.

"We are now beginning to reduce the number of crews on scene, but we expect to be here throughout this morning fighting this fire and making the area safe. Please continue to avoid the area if you can."

At 7am, three crews, including the water bowser, remained at the scene.

Firefighters were continuing to eliminate hotspots in the area and within the structure of the building.

A full fire investigation to understand the cause will take place once the fire is fully extinguished.
