Symbology of single line diagram in british standard BS 7671.2018

I need to convert some single line diagrams into BS7671 single line diagrams. 

I don't think BS 7671 has any peculiar demands for line diagrams .. just that any symbols used comply with IEC 60617 and generally 'all diagrams, charts, and information or instruction notices' to comply with BS EN 61082-1, BS EN IEC/IEEE 82079-1 and/or BS EN 81346-1, as appropriate (BS 7671 519.9.2).

As Andy says, the standards to follow are listed in Section 514 of BS 7671.

That is the basic standard for electrotechnical diagrams/documentation.

That is the standard for symbols.

Regards the sample you posted, looks pretty 'standard' to me ... just to note that we no longer use 'R', 'Y' and 'B' for phases (they should have been abbreviated  'RD', 'YE' and 'BU' according to the standard colour code anyway) ... we use 'L1', 'L2' and 'L3' instead.

Table 51.1 of BS 7671 has the colour codes and conductor abbreviations we use, if that helps.
