The boiler st8 has ns, ls, lr and spare.
My thermostat has c, on and off

Just take the service and installation manual and look up electrical connections. Then get the installation instructions of your roomstat, and all should be clear.
If it is not clear with the help of the 2 manuals, you should get a pro to do i t.
Bear in mind you will be working with 230V, so any mistakes can have serious consequences.
