I fitted a thermostat and it works just as a thermostat should except
that it will only click (led lights up) when dial is turned to over 25
and it fires up the boiler (0-25 - nothing at all). The house is cold
these days and i need this sorting ASAP. can anyone advise?

Sounds like youve connected to the wrong connection on the stat, so its
working in a/c mode. Apart from the neutral, there will be 3
connections, common, heating and ac, and you need common and heating
not ac.( Whether theyll be marked as that is another matter)
