The massive fire in Sudbury town centre on September 6 is likely to have been started by an electrical appliance or wiring in the kitchen area of a nail salon.
In October the Free Press revealed Suffolk Fire and Rescue Service (SFRS) believed the fire had started in the kitchen area of Celebrities Nails in Market Hill, with forensic analysis of materials from the building required.
Investigations into the cause of the fire are continuing, but it is believed the cause involved electrical wiring or an electrical appliance.
A full report will be published once the investigation is complete.
A spokesman for SFRS said: “To the best of our knowledge, and given the seriousness and extent of damage to the building, the fire most likely started in the nail bar, at low level, and involved electrical wiring or an electrical appliance in the rear kitchen area.
“This report is still under review by us and we are not ready for full publication.
“As is normal, aspects of the draft report have been shared with our partner agencies as part of the investigations.”
The spokesman added that SFRS needed to be “categorical” about the report’s contents, ensuring they were certain of any causes before it could be released.
“There are still areas we are looking at,” he said. “It is still under review.”
It is reported the fire was also fuelled by tissues and paperwork but acetone chemicals used by nail salon staff did not contribute.
These were found undamaged in the basement.
Twenty households were forced from their homes by the fire, with several properties completely destroyed.
The 19th Century Goldsmith’s Mansion building, which included Celebrities Nails, the Oxfam charity shop, and accommodation, was completely destroyed as was the Cobblers and Keys Locksmiths.
Fashion retailer Javelin and HSBC bank were also severely damaged.
A trust to distribute donated monies to the victims of the fire has been set up and is looking for those affected to make contact.
