But nothing in the regs? The load of the washer is 2200 watts with a built in heater and the dishwasher coming in at around 2000 watts. My plan is 2.5mm2 wire and a 20amp MCB. Washer will be plug and socket while the dishwasher will be hard wired, however that can be changed to a socket if regs forbid it.

What recommendation is made for appliances over 2k?
Nothing? Unless you install dedicated circuits for the likes of toasters, kettles etc. 3kw is the general cut off, although doesn't stop a tumble dryer being plugged in anywhere!

you can only estimate. even if they are both on at the same time, they will not always both be on heat cycle, and even then, it's only 18A (assuming you have a 240V supply, not 120V).

What voltage are they on?
I believe you chaps over there have different voltages than us here in Blighty.
