Righto, I'll try another one.

Is this something you've come across before? It's not the appliances themselves, it only happens when their power switches don't engage properly, like how you can make a striplight rocker switch crackle.

Is your suspicion that the wiring is dodgy or the CU? The reading lamp which sometimes causes it is upstairs, so it happens on more than one ring.

power switches built into the appliences or switches on sockets etc?

if you are turning the socket switches on and off regularly, and they have never been changed then after 20 years they may be worn out.

Hi - yes, but the only one I’ve worked on was a double pole switch where I’m pretty sure the N was bouncing and that upset the RCD. I replaced the switch and it stopped doing it. In your case with multiple switches doing this I’m thinking your N and E not might be 100% anywhere from supplier cutout through to the end appliance. Changing a switch is one thing, but I think it’s time to get an experienced Electrician to test and inspect.

It's the on/off push switches on the appliances that cause the trips*; they're all left switched on at the wall. *plus the fridge door when it doesn't close fully if not pushed hard enough

I think wilko has probably hit the nail on the head, rapid energising/de-energising of appliences when the switch is arcing is probably causing an imbalance that the rcd is seeing as a fault.

I forgot to state that the appliances are new. Apart from the fridge door!, the ones that I have trouble with are power buttons such as these:
