Electrical wiring quality has less to do with the architect's plan than with the specific electrician who ran the lines, and the shortcuts don't announce themselves. A distribution board rated just under the home's real load, or an earthing connection that's present but never actually tested, will pass a casual walkthrough and cause problems only once the home is fully lived in.
A few things are worth confirming before you sign off: that earthing is tested, not just installed; that the MCB and distribution board are rated for the load you'll actually draw, not the minimum that passed inspection; that switches and sockets carry genuine fire-safety-rated components, not the cheapest lookalike; and that socket points were placed against your actual furniture plan, not just wherever the wall made wiring easiest.
This is exactly the kind of check worth doing with someone who isn't the one who wired the house. Bring us the load list and layout before final fit-out and we'll sanity-check it with you.
