Quick update. Can't get plumber til next week. However, turned central heating off and left hot water on and it's working fine. Must be something to do with the heating. I bled the radiators and two of them up stairs are struggling to get any water out of them. All others are fine.

I'm kinda thinking that there may be a block somewhere??
