My heating is only partially working. If radiators upstairs are turned on they seem to overheat and it is boiling upstairs but the downstairs radiators don't heat up at all. If I turn all the radiators off upstairs the heat very gradually comes downstairs and the radiators eventually heat up. Is this a problem with the pump?
have bleed the radiators and yes can hear pump working

if the downstairs rads are on a drop system and your heating system is old you could have a different problem but id def start looking at pump.

Does sound like it could be a pump problem (can you hear the pump working?). One thing I would try is to "bleed" each radiator to make sure there isnt any air trapped in the system. You need a radiator key from a DIY store and loosen the valve at top end of each radiator to release any air - when water squirts out the air has been removed.
