Me,
A very slight disadvantage is perhaps that someone could plug a low
wattage device (eg a 40 watt lamp) into your 32amp supply socket.
But they'd have to crawl behind the kitchen units to do it.

I think your way is best. I'll see if there's a socket with the word
"cooker" on it in red, and use that to complete my installation, which
would somewhat overcome the above.

Thanks

Tony
