@redwood98, the portable 13A granny charger looks to have all the protection for something that plugs into a UK 13A socket. Third Rock have all the usual safety information about the type of socket to be used, and not using an extension lead.
If you are talking about the 32A CEE bundle with PME unit then, while you can buy this sort of bundle, getting it fitted domestically would be a problem. There is some debate over whether either the 16A or 32A CEE form connectors comply even if they have a locked and electrically switched output. The Third Rock bundle shows neither of these features on the socket shown.
There are then considerations when using this amount of power (up to 32A) if your supply is suitable. You may have a looped supply, or the supply cable/ board fuse is not the right rating. These would normally be checked by a home charger installer in a servey and if required changed or updated by the DNO.
So in short, while this bundle is available to buy I don't think you'd get any reputable and certified electrician to install it.
