The report mentions a tilt-and-turn window next to a night vent. Has a trickle vent painted shut been tested, or only named?
The trickle vent painted shut has only been named, not tested. A tilt-and-turn window can tilt inwards and also turn open, and a night vent is a small vent position or a separate night ventilator beside it. Paint across a trickle vent is a visual note that the slot is skinned over. The survey has not measured airflow, has not decided the room fails any ventilation expectation, and has not said the window gear is at fault.

What is the fuller explanation?
A trickle vent is a small slot, usually in the head of the frame, meant to pass a little air when the sash is shut. Paint can seal that slot. A tilt-and-turn opening and a night vent are other ways air might still move. Naming them records the hardware. It does not measure airflow, and it does not show whether the painted slot is sealed or only looks painted.
Tell the solicitor the painted trickle vent was named and not airflow-tested. If you want the slot working, a window fitter can clear it or say whether the vent is still there under the paint, as a separate job. The home survey has not ordered that. The lender has no ventilation measurement. Do not read the tilt-and-turn function as a substitute test of the trickle vent. The painted slot stays an untested note.
What should you ask your surveyor?
- Was the trickle vent painted shut only named?
- Did you leave airflow through that slot unmeasured?
- Was the tilt-and-turn gear kept separate from the painted vent?
What are the typical next steps?
- Treat the painted trickle vent as named, not tested.
- Ask a window fitter if the slot must be shown to work.
- Tell the solicitor no airflow reading was taken.

Also asked about this
Does a working night vent clear the painted trickle slot?
No. A night vent is a different opening. The trickle vent painted shut is its own note, and it was not tested. One path that opens does not prove another path that looks painted. The survey did not trade them off. The painted slot stays unmeasured.
If the tilt mode opens, has ventilation been passed?
No. Tilt is a way of opening the sash. It is not a test of the trickle vent, and it is not a measurement of how the room is ventilated with the window shut. The survey named the hardware. It did not pass the ventilation of the room.
