    An unusual thing that I have never seen before, from the air brick to an underfloor void they have condensation on the vent and a wet patch on the adjacent path. Solid floor with ufh on.

    Anyone else seen anything like this?

    Sorry, if it's a solid floor how is there an underfloor void?

    Suspended concrete, probably beam and block or concrete planks
    If it's condensation this implies warmer air with a high RH is being cooled ........ Hmm
    Suspect UFH might be leaking or some other water entering the void (including ground water / moisture) and the UFH not being too well insulated is heating the void and evaporating the water /moisture which condenses on leaving through the air brick
