Four fire crews were drafted in to tackle a fire for six hours at a large agricultural building near Builth Wells.

Mid and West Wales Fire and Rescue Service said fire engines from Builth Wells, Llandrindod Wells, Presteigne and Knighton were sent to a farm in the Hundred House area on Monday, January 6, at 9.26am.

Firefighters arrived at the scene to find the barn “well alight” after it was set on fire by a small agricultural vehicle.

Fire crews isolated the electricity to the barn and extinguished the fire using four hose reel jets, 12 sets of breathing apparatus and a water carrier.

The fire service said the agricultural building, measured around 45 metres x 28 metres, was used to store straw and farm machinery.

Telehandlers were used to remove burning straw from the barn, which was then left to burn safely in a field.

Mid and West Wales Fire head of Powys Command, Craig Thomas praised the firefighters successful work on Twitter.

“Well done,” he said. “I have been briefed and top work by crews preventing fire spreading! Crews were in attendance for six hours.”

Llandrindod Wells Fire Station said it was a “busy day” after receiving five callouts which included a two-vehicle collision in Llanbister.

The fire service left the farm at 3.14pm.
