2.6.5.1
Street Names, towns and localities must include all abbreviations that are in the official version of their name. For examples, see Section 5.4.
2.6.5.2
If a type 2 Street includes the name of a town, locality or a type 1 Street, then it must include the same abbreviation as the Record for the town, locality or type 1 Street.
2.6.5.3
If a word is spelled in full in the official name, then abbreviations must not be used. The exception to this is “St” for “Saint”, which is permitted. If abbreviations are used, they must not include a full stop unless the full stop is part of the official name. If there is any doubt about the inclusion of the full stop in the official name, it should be omitted from the NSG.
2.6.5.4
The ampersand symbol “&” must be used only as a replacement for “and” if it appears in the official version of the name of a town, locality or Street. In type 2 Streets it must only be used where it is unavoidable.
