Crews from Hitchin, Letchworth and Baldock, and Stevenage are in Whitehill Road, Hitchin, where a house roof is said to be ablaze.

They were called at 11.26am.

Eyewitness Alison Wood said visibility on the A602 was restricted.

She tweeted a warning to drivers, adding: “Hope house (is) empty, was just calling 999 as crew arrived on scene.

“Cars in danger smoke billowing. Suspect road may close?”

The fire service said one person escaped the house – a bungalow chalet – before fire crews arrived.

The ambulance service was called and spokesman Gary Sanderson said a fast response car had been sent to the scene, where a woman was being assessed. She did not require hospital treatment.

Police have confirmed they were called, and shut the road by Whitehill Junior School.

The cause of the fire is accidental.
