BS 1363 13 A plug tops

Appendix 6 of the latest (5th) edition of the IET Code of Practice for the In-Service Inspection and testing of Electrical Equipment states under appendix 6 (user checks and formal visual inspection) ‘Only one flex connected into one plug, unless it is specifically designed to accommodate more than one flex.’.

Clearly this is a code of practice, and not a formal regulation, but if you want something to point to then you can use this.  It is not good practice.

Pragmatically, as Mike said, if the cables are adequately secured by the cord grip (may be difficult to ensure given they are designed for a single cable) and the cables are small such that the conductors properly sit in the terminals and you are sure there is good contact with both then you may not deem it to be ‘unsafe’ but there are better solutions that avoid this particular shade of grey.

Can the socket be fitted with a conversion socket to change it to a twin?

Use a short extension cable (say  0.3-0.5m) with a twin outlet on the end to allow the split.

Gland both cables and a supply cable into a small junction box.

Change the 13A plugs for IEC C13 plugs, and use a pre-moulded 13A - 2 x IEC ‘Y’ cable.

Personally I would favour solutions that don't join the wires together in a fixed way - much better for maintenance and isolation purposes if there is an issue with one of the chargers and not the other.
