Is this a sign of a serious fault or something that can wait till after Christmas?

"Good morning, there could be a couple of reasons why.

Have you checked the simple things like pressure?

If you are able to reset it and it comes back on then I suggests that it's not too severe and shouldn't cause any further damage but I would definitely get it checked over by a gas safe engineer"

"This is normally down to an overheat issue. It can be a problem with circulation on the Central or possible blockage we would always advise you to get an engineer out soon rather than later as these problems do not solve themselves
