Simple yes - NO
The Neff happily runs off a 13 amp feed but the AEG is 3.5kW and the specifications calls for it to be fused with a fuse rating - minimum 15 amp maximum 20 amp
Now the feed from the consumer unit is a 30 amp rated fused spur which at present feeds the built in 1000 watt microwave and the oven via individual 13 amp fused DP switches
Thinking laterally
I could replace the 30 amp fuse with a 20 amp fuse then the maximum power would be about 4.8kW which would be adequate for the two units and replace the 13 amp fused switch with a 20 amp DP switch
Would there be any problem with that

But yes, what you describe should do the job...

It is a bit silly in that I totally rewired the kitchen in my present house before the new regulations came into effect - major extension to the existing ring main - and completely rewired my previous house with a new consumer unit and followed the regulations to the letter (which is more than the "competent" electrician did - 3 double sockets on one spur off the ring main)

As for signing off and what they give you, dunno to be honest, never had that done myself, but I do know that such documentation has to be seen by your insurer, supplied by yourself I presume, and how do they know about it, well, firemen inspect the building to find the root cause of a fire, and they usually find it and write up a report which somehow goes to the insurers so they know whether to say "you made the mess, so you're boned buddy!" or not...

The next question is discrimination, so that the downstream fuses trip indevidually before the backup fuse. For this you need the characteristic curve for each fuse and check they dont overlap. When designing such circuits we used to use HRC fuses for best discrimination.

Originally I was going to leave te 30 amp fuse in the consumer unit and add a 20 amp fused spur
However there doesn't appear to be any such unit available
Regarding diversity - in this case it isn't practical as the oven unit and microwave are often used at the same time on full power - so a 20 amp fuse is needed on the feed to the two units
Note that as presently fitted it has a 30 amp fused spur up the the point where the oven and microwave are connected using individual 13 amp fused spurs (the 30 amp fused spur was needed originally as the original unit was a double oven where you could use both at the same time)

Regarding diversity etc, is *all* of the oven on at any one time? I suspect that the 3.5kW rating is derived from adding up top, bottom, side elements etc and I'd be surprised if you're cooking with all the elements on?

This could be when doing the pyroclean or the fast heat up option
Note that the oven specification is for a fuse of not less than 16 amp and not more than 20 amp and it is rated at 3.5kW
Regarding the small enclosure - that would certainly be a viable option - will need to check

At any given moment in the universe many things happen. Coincidence is a matter of how close these events are in space, time and relationship.

This enclosure http://www.screwfix.com/p/wylex-ip40-insulated-enclosure/32311 with one of these http://www.screwfix.com/p/wylex-16a-sp-type-b-mcb-6ka/88460 would do the job

The MCB is single pole of course, so you'll also need something to join the neutral and earth cores.

Actually adding another DP switch possibly isn't essential but would probably be a good idea
