There are number of ways forward:

1) If the boiler is fires up and never stops on its own thermostat until
it's turned off then it simply is not powerful enough, or there is something
very wrong with it. This is possible but less likely than (2).

2) The pump is simply not pushing the water around hard enough. The boiler
is working fine, it gets hot and cuts in and out as needed but the water
is not moving around well enough for the number of radiators and size of
house and size of pipe work in your installation.

3) As (2) but the pump has become very ineffective - I have known pumps to
erode away in adverse circumstances.

Details of the make and model of boiler would be useful also is the pump
in the boiler or is it elsewhere. If the latter then it may well be a two
or 3 speed unit and all you have to do is turn it up a notch.
