It may depend on the locality. Homes in villages had no sequential numbering system until quite recently, and some probably still don't. Local postmen usually knew where people lived and didn't need one. In the small town where I live most addresses on the main street had names (and still do); when they were numbered half of Main Street was renamed High Street, and the numbering started from the centre for each half. Homes usually appear in order on the census, but that doesn't necessarily offer reference points for today. A contemporary 12-inch OS map may help, if available.
