Worcester 24i combi boiler not firing up?

quite possibly that the condensate pipe is frozen. This would cause the boiler to lock out. If you look under the boiler and put a bucket underneath, and pull the plastic condensate pipe out of the socket, and let it drain into a bucket until the weather picks up
