Who can advise on the regulations for EU plugs on electrical equipment

Question posted by Dan Heaney

I want to start supplying my electrical products to Europe fitted with appropriate CEE 7/7 european plugs.

Can I cut the UK plugs off and fit CEE 7/7 Schuko plugs or do they have to be moulded on?
Are there additional regulations?
What authority can give me definitive answers?

Please do not recommend the BSI as they seem to have given up giving export advise now they are a private company.
