If the equipment is permanently installed, hard wiring is the preferred solution. Otherwise a plug should be used. The IEC 309 series is acceptable worldwide now. I see them commonly used all over including Great Britain. They are wired on a separate branch circuit with overcurrent protection provided at the source instead of relying on a fuse in the plug to protect the lower rated flexible cord and appliance. Unlike the IEC 320 series, the IEC 309 variations are unique for each voltage range. That means you can't make a single universal product model for all voltages. However matching the plug to the operating voltage is not usually a hardship for large loads. The IEC 309 series is well accepted in North America as well, however the NEMA twist lock styles are more commonly available and less expensive.
