Welcome to ECN Plugman!
If, in the near future, the powers that be in the EU say 'Sorry guys, we want you to harmonise with rest of the EU, so the square pin plug has to go!'.
Possible, but not very likely.
Though whatever round pin system you picked to replace it had to take the 2.5 amp europlug as a minimum, What CEE 7 based or related earthed/3 pin system would you pick?
The 2.5A Europlug has the problem of fitting BS1363 sockets with a little help. The low load means that there is virtually no risk of overload. But any plug with a higher rating will need to be incompatible with BS1363.
Personally I would go for the French UTE plug/socket style, at least it is polarised when the grounded plug is used.
Yup, but the French don't care.
The EU would never, ever, force Britain to change to another plug that is already in use. If you do change, it will be the BSI who have made this decision. (But they will of course blame the EU) The EU might force everybody to change, but that again seems unlikely at this point of time.
