All my radiators are working fine except my hall 1, which is hot at the top but stone cold at the bottom??????

Could be a build up of sludge. If it's only the one radiator, you can remove it and flush through with a hose pipe.

When refitting you might want to consider adding some sludge remover and running heating for a few days, draining then adding inhibitor to prevent the same happening to other radiators and boiler
