My condensation pipe was frozen and I've now fixed the problem by unfreezing it but before I did that I'd already increased the water input as the dial showed no pressure. Obviously the pressure is now high ( almost in the red -4 ) how do I now reduce the pressure ?

By opening the drain off, small brass thing normally on the outside of your property some where, to realease some water. Or a little longer way is to take the water out of your radiator via the way you normally bleed the radiator for air, have a bowl or something to rain the water into, but remember to switch your boiler off while doing it.

Possible frozen condensate pipe outside or blocked flue. possible water ingress inside boiler - remove boiler cover and inspect electric connection compartment
