Flames swept through the lofts of three terraced homes in Downham during the early hours of this morning (Tuesday, February 3).
Six fire engines were called to Elizabeth Avenue at 3am after families raised the alarm.
No-one was injured in the blaze but ambulance officers assessed two adults and six children.
Fire broke out in the loft of one of the homes and spread to the two neighbouring properties. Luckily firefighters held it back from before it had moved onto the fourth home.
Crews from Downham, Lynn, Methwold, Terrington, Littleport, along with the water carrier from Fakenham and the welfare unit from Attleborough attended.
Tim Edwards, Lynn fire station manager, said the aerial ladder had been effective in fighting the flames.
He said: “The fire spread through the first two properties and there was some damage to the third but we stopped it going across to the fourth.
“It was difficult but luckily we gained access with the aerial ladder. We had difficulty with the water supply.”
Norfolk Accident Rescue Service Critical Care Paramedic Ryan Warwick attended.
A NARS statement said: “Ryan assisted the ambulance service to assess eight patients (two adults and six children) using a specialist monitor that measures carbon monoxide levels, thankfully none of the patients showed any signs or symptoms of carbon monoxide poisoning and were left in the care of the ambulance service.”
