The series starts as middle-class couple Terry and June Medford prepare to move into 26 Elmtree Avenue in
Purley,
Surrey. They are in their late 40s and have a daughter named Wendy, who is married to Roger; both are rarely seen. Terry's nephew, Alan Medford, pays occasional visits where he always causes some form of trouble. Terry can be headstrong and determined, but often as a result of his childlike enthusiasm getting the better of him, and his plans and schemes normally end in disaster. June, meanwhile, is tolerant of her husband, but frequently doubtful about his ideas and acts as the voice of reason and common sense, although this often falls upon deaf ears. Terry works for Playsafe Fire Extinguishers and Appliances, and his boss is Malcolm Harris. In a continuity error his surname is sometimes referred to as Laurence instead of Harris. Malcolm frequently has affairs, and he and his wife Beattie, a friend of June, often argue. The owner of Playsafe is Sir Dennis Hodge (
Reginald Marsh, who played a similar character in
The Good Life), a grumpy man who rules the company with a rod of iron. His personal secretary of over 20 years is Miss Nora Fennell, whose fondness for Sir Dennis is not reciprocated. In the first two series, their neighbours are Brian and Tina Pillbeam. From the third to sixth series, the Medfords' neighbours are Tarquin and Melinda Spry. Terry and Tarquin frequently compete against each other. ==Episodes==
