Can I use 1.5mm cable to supply a single socket. Cable will run behind a plasterboard wall. Cable run will be about fifteen centimetres. Breaker is 20amp for the circuit. The intention is only to use to supply a low current device (home automation microprocessors).

1.5mm2 cable for single socket?

Wait for it......"But what if someone plugs a 3Kw heater into it".....
I'm no electrician but why not run two 1.5mm cables if that’s all you have?

1.5mm² can take 20A.
Yes, you can use it.

Go outside a screwfix/Toolstation and when you see an electrician van ask to buy a piece of 2.5mm2 cable.
Failing that, invest the grand sum of £9.99

Really?
So why do they wire all sockets with 2.5mm?
Genuine question, i don't know.
I think it's because a double socket would exceed the current rating. Rating is also less than 20a when concealed iirc.
Plus the MCB is usually 32A.
As has been said, 1.5mm² cable would be more than enough for a 3 kW heater.

That, in itself, is irrelevant - (the common situation of) half a dozen (or more) double sockets on a circuit wired with 2.5mm² cable would dramatically 'exceed the current rating of the cable' if all the sockets were fully loaded.

or a 4 way splitter with 3 heaters in addition to the automation.
What is a 4 way splitter?
Your ignorance astounds me. Google is your friend.
I have googled 4 way splitter as requested. How should I connect 3 heaters to any of these?
Extension lead maybe?
Just a wild guess, or maybe it's a technical electric device.
