The burglar attended the woman's home in Silver Jubilee Close in Wheatley, Doncaster, stating he needed to undertake checks inside the property.
The woman let the man in, but became suspicious after he asked her to run the kitchen taps. She went into her living room where the man was and he fled the scene.
The woman checked her handbag and discovered £1,000 was missing.
