His report found the fire had started in the shelves under the reception counter, where the intensity of the fire had burnt most of the electrical devices and wiring which had been there.
There had been a Menulog device, a multibox, a modem and a pair of tablets which were on charge there, but the devices were so badly damaged in the blaze that a specific origin point could not be identified.
The was a lot of wiring found in the vicinity of the counter which was "not stored or maintained well" with some wires being bent, poorly stored or having heavy items lying across sections of them.
Information provided after initial investigation found the Menulog device failed an electrical test conducted after the fire, which could have been a factor in sparking the blaze, the report said.
The restaurant itself was described as "untidy and cluttered" but with no sign of rodents which might have sparked a fire by chewing through cables.
The fire caused severe damage to the business' interior, with damage to a flight of stairs above the reception area and burnt furniture in the dining area, where the glass door of a drinks fridge shattered in the high temperatures.
The upper floor of the building, used for storage, escaped unscathed but the kitchen was left covered in soot and stained from smoke, with melted light fittings.
The fire was ultimately recorded as an "accidental electrical event", the report said.
