Does anybody make a 2G 13A socket that is suitable for connecting two appliances which are rated up to 3KW each, which may be used simultaneously, or is the only solution two single gang sockets on a 2X1G back box?
2G socket for 2X13A load.

Possibly he has two appliances under 'tops - washer & dryer or such like.
Best to use 2 x 1G sockets if the load will exceed 13A.

26A from a single point (or rather two lots of 13A slap bang next to each other) is not necessality an issue, the requirement is for the ring to be designed in such a way that it won't be too unbalenced in normal use, if the loads are close to the centre then its likely that this requirement will still be met
Yebbut, I read on another topic (that I can't find at the moment) that a 13A socket was rated at 13A because the point of cable connection had too little surface area to support more, and that this is why a double socket was also rated at 13A. 
Presume you mean this one

Well done - that's the baby!
I've just been reading that thread.
Yes, the load is a washer and a drier.
The loads are both intermittent in the terms of the experiment data quoted from MK in that string, where the load was maintained for about 40- odd hours, but of course can be concurrent, hence my concern.
I believe the power consumption of the washer is about 1.8KWH per washing cycle, that takes about 2 hours, implying about an average load of 4A, but as we know, this will vary significantly throughout the washing cycle, especially whether the heater is in use or not.
The load from a tumble drier will be more or less constant at the plated load, drawing 2KW ('cool' setting) or 3 KW ('Hot' setting) for 1 1/2 - 2 hours, so the duration of the 'overload' is significantly less than that in the MK experiment.
I noted the concerns over the current carrying capacity of the cable terminations and the plug contacts.
Data like the time taken for an 'overloaded' 13A double socket mounted in a typical enclosure to reach a temperature that reduces it's working life, compared with similar data for for two adjacent single sockets, and two singles mounted in the same enclosure may be helpful to make a better informed decision on the choice of accessories.

you can get a dual box that allows 2 single sockets to be mounted side by side, or homebase sell a range of sockets that have two singles in there doubles (but they are expensive so a dual box may be better).
as has been said two single side by side with high load still isnt ideal but better than a double. if you are rewiring wire the ring so every alternate socket is wired on the way out and then all the others n the way back, include the two single in this and although they will be physically next t each other as far as the ring goes they will be apart.
