Is pump running correctly
Switch the boiler stat to low and report back.

Clamber up in the loft and make sure there is some water in the small F&E cistern. Sometimes the valve sticks in the 'up' position.
If there is a manual vent near the cylinder you may be able to bleed some air out of it.
Has anyone tampered with the bypass valve?

pull the overheat stat out and see if it boiler cuts out
If there was a problem with the overheat stat then the pilot would go out.
How many radiators do you have connected to it?
Are they all turned on?
Are TRV's fitted?
What you can do as a DIYer is help discover any causes of slow flow through the boiler. Normally a slow flow through these boilers is accompanied by noise so once we can be sure of a good flow we can move on.
Next is the temp sensors [hi & Lo stats] whose job it is to turn of the gas at one of 2 temps. Normally people run these on the high setting. I assumed that if you turned it accross to low although slightly self defeating as shutting the boiler off at a lower temp would result in a shorter burning cycle, I hoped you would have noticed a difference. Hopefully we have ruled the hi / lo stats out now.
That leaves us getting into Corgi territory.
The fans on these frequently stiffen up and cause problems sometimes taking the pcb with them or the pcb goes on its own anyway. Very expensive and the reason that these boilers are often regarded as craap.
A flue or fan fault could be indicated by the flame lifting off the burner.
What you can do is look for flame lift, lube the fan bearings with 3 in 1 oil, and have a sniff around the flue pipe to make sure it is intact and unblocked.
There is little else we can do to help here so it could be time to get someone round to sort it now if you want to be warm 4 christmas.
