We've recently had the radiators taken off and put back on during some work which was being undertaken - prior to this heating and hot water working fine, however now the heating is turned on, the boiler (Vulcan Continental) is hot, but radiators remain cold as does water?

Note there are Potterton attachments to the hot water tank.

Does anyone know what may be the cause?

sounds like an air lock, u will need to locate the pump,there will be a bleed screw on the front open it and leave the heating running, u should eventually get a steady stream of water from here when the system is bled of air

Thanks Andy, we have bled all the radiators although no air came out. If the air is stuck in the pipes how would we go about getting this out?

Sounds like air in your system.
Have you made sure the radiators have had all the air bled from them?
