Can a double socket be fitted directly above a further double socket?

First and foremost, you should have recieved a Minor Electrical Works Certificate for the job. If the electrician has not issued you with a certificate then you have no evidence/audit trail that the work was crried out to the requirements of BS7671:2008 and has been properly tested. The positioning of a socket directly above another one it itself is not unsafe. It probably looks a bit odd as it not a common practice. Provided both sockets are not spurred off the original (i.e. the original ring or radial circuit has been extended properly) then there should not be an issue. You do not say which room the sockets are in, but if its the kitchen, then part P of the building regulations also applies and the completed job should have been registered with your local building control department. - Failing to comply with part P of the building regulations can result in a fine of up to £5000 Hope this helps, please click on "like" if it does.

Hi, Basically there is nothing wrong with the position as long as he's wired it correctly. Many thanks Thom

Appendix 15 of BS7671 which describes Ring and Radial Final circuit arrangements states that an unfused spur should only feed one single or one twin socket outlet. This spur should be run in 2.5mm If your electrician has extended the ring in to one of the new sockets and then carried it back around to the original then all is ok.. If not it's not to code and should be sorted - the easiest way is to extend the ring. failing that an additional fused spur needs to be put in and load calculations done.

I am not an electrician so I will not comment on these questions.
