strung together this:

what is the correct cable to use to connect a thermostat to a combi boiler?

Well, depends on which bit of the wiring you mean, and at what voltage
it operates. For mains wiring from the thermostats location to the
boilers location flat fixed wiring cables should be used, usually twin
and earth or three core and earth (6242Y or 6243Y).
For the final connection to the boiler is usually by flexible cables,
cored depending on your requirements. Also, the matter of using heat
resisting cables depends on whether the manufacturers call for it or
not, if you're unsure then use heat resistant.
The connection between these two cables would usually be either a flex
connection unit on the wall or a junction box somewhere close by,
although the former method is better.
For low voltage wiring, pretty much anything goes!
