Winston is regularly referred to as a social worker, when carer would be a more accurate term.
The Garnetts, with Mrs Hollingbery upstairs, live at 8 Maitland Terrace, in the London Borough of Newham (tel: 01-4711290 from the third season). However in the fifth season Alf claims the house is 59 Mandela Road (formerly Tinto Road), and the penultimate episode has it as 54 Mandela Road (formerly Herbert Morrison Street).
In Australia Alf, Mrs Hollingbery and Arthur speak as if Winston is still living with Alf, when he had already been replaced by his cousin Pele.
