    I have the heating on constant, but it kicks up for probs 30seconds then shuts down again, 2 minutes later the same thing happens, even tho the rads are freezing!

    Ignition/sense fault. Usually ignition PCB on this marvel of a boiler. Get someone to have a look and rectify.

    Is it a combi and is the DHW working normally or not?

    That time scale makes me wonder if its a CH sensor failing when it gets warm.

    With the boiler cold measure the resistance with the lead off.

    I will stick my neck out here and say it was a Friendly Format 80 c Tony. A combi. CH sensor fault will make LED go orange.
