I notice from the central heating diagrams that 4 (and sometimes 5)
connections need to be made between the junction box and the programmer.
Is there a particular cable for this or is it usually knocked up with a
couple of runs of twin and earth?

Thanks

There are many multicore flex and cable manufacturers and many different
styles of to choose from. This particular one will take mains voltage up to
a maximum of 10 Amps which is more than enough for a central heating control
panel or timer / programmer installation.
