Central heating works fine but I can't get any hot water! Boiler fires up but switches off after a few minutes when on hot water only. Help needed please!

Hi Mark, you may have a zone valve shut down somewhere, most have a lever on the side that you can opperate manually, open it up and try the boiler again, failing that, you could have an air lock in the hot water side, look for a vertiacal bleed vent.
