Maximum number of Power Outlets
I really think you should get it checked out.
With 10A socket outlets there is a requirements for at least 2 circuits. This appears to have been met.
You have not mentioned whether there are circuit breakers or fuses. Nor have you mentioned whether you have a residual current protective device (RCD or earth leakage).
Were the 10A socket outlets circuits protected by a breaker of 16A and supplied by 2.5mm2 cable, then you would be permitted 15 socket outlets per final subcircuit.
You can only overload the wiring if the protective devices are not correct ratings for the cable installed. A 10A breaker or fuse rating is well and truly protecting cables and socket outlets but really seems too low a tripping or fusing rating. I would be looking at 16A protection of 2.5mm2 cable unless you have more than 15 GPOs installed in which case I would recommend 20A. If you have too low a tripping capacity (ie 10A) it may well result in unneccessary circuit breaking.
If you do not have an RCD then seriously consider having one or more installed.
