    Morning. We do not judge the level of pressure in the system when hot. If it is Between 1 and 1.5 bar when cold, this is fine. If not get a jug, vent a radiator and catch the water inside the jug until the pressure is at the correct level.

    If it's fully hot and doesn't go over 2-2.5 bar your fine

    If it goes higher just get a container and bleed a rad

    Good advice here about the high pressure. But I would not recommend bleeding rads when they are hot. To easy to scold yourself. But that's just my opinion.

    I do it all the time to be honest mate. But I'm insured for that.

    Thank you everyone, it’s what I thought but wasn’t sure! I didn’t want to mess up on the last leg of my bathroom re-furb.
