Police are appealing for witnesses after burglars broke into Whitehall Garden Centre near Lacock late on Sunday night.
Offenders got in by smashing a window and once inside they set off a fire extinguisher and stacked up Morphy Richards and Delonghi kitchen appliances.
But they were disturbed by security staff and made off. Police searched the area just after midnight but found no trace of anyone.
Anyone with any information should call Chippenham Police on 101 or call Crimestoppers on 0800 555 111.
