    Checking the radiators as the rooms upstairs seem to be much colder.
    It seems that the some of the rads are heating unevenly - hot at the top and cold at the bottom.
    I checked and they are bled - water only, not air coming out.

    Gas boiler was replaced about 2 years ago.

    Any ideas please?

    Typically a sign of a slugged (gunk) system. Reason for this happening needs to be corrected, then a powerflush.

    It can also be caused by poor circulation of water at a high enough temperature.

    If you turn off a few (or more) of the ones that are heating, if then the colder ones heat properly, it's most likely the latter.
