These pictures show the devastation that has been caused by the fire.
A major incident was declared last night by Hertfordshire Fire and Rescue Service.
Fire fighting services sent to the scene included 15 fire fighting appliances, two aerial ladder platforms, a high volume pump, an aerial drone, a command and control unit, an incident support unit, and 11 flexi-duty officers.
Herts police and the East of England Ambulance Service also attended, with no casualties reported.
Residents continue to be advised to stay indoors and keep their windows closed due to the smoke.
A number of local residents lost their water supply and suffered power cuts.
One of the owners of London Twenty Four, a members club due to open soon in the estate, told us that "the whole building has collapsed, and now it's just gone".
According to Marsh Detailing, one of the companies based in the industrial estate, "a lot of businesses have been lost". Herts County Council say that more than 40 units have been affected.
Sir Oliver Heald, the MP for North East Hertfordshire, has thanked the emergency services for "their hard work and professionalism".
