A tilt and turn window does two things from one handle: turned 90° it tilts inward at the top for secure background ventilation; turned 180° it swings fully inward like a door, so the outside face can be cleaned from inside. Typically £850–£1,250 fitted.
Above ground floor, and especially in flats, tilt & turn is usually the only sensible choice — you cannot lean out of a fourth-floor window to clean the outside of a casement, and most freeholders will not allow it.
It also solves the ventilation-versus-security problem. Tilted, the window is open at the top by 100–150mm, ventilating the room, but the hardware is still engaged at every locking point around the frame. You can leave it tilted while you are out in a way you would never leave a casement swung open.
The frame is only half of a tilt & turn. The other half is a geared espagnolette running the full perimeter, with a corner drive at every corner and a tilt-and-turn stay at the head. It is more mechanism than any other domestic window, which is why the price sits above a casement — and why the quality of the hardware is worth paying attention to.
If a tilt & turn drops, binds or won't lock, it is nearly always a gearing or an adjustment issue rather than a frame fault, and it is repairable.
A tilt & turn in full turn mode gives an enormous clear opening — comfortably over the 0.33m² required for an escape window, with a 450mm minimum in both directions. That makes it a straightforward way to satisfy escape requirements in a bedroom or loft conversion where a casement would need special egress hinges.

A window with two opening modes from a single handle: tilt (the top leans inward for ventilation while the frame stays locked around the perimeter) and turn (the whole sash swings inward like a door). It is the standard window across most of Europe and is common in UK flats and apartments.
Yes — typically 15–25% more than a casement of the same size, because of the perimeter gearing and the heavier hinges required to carry an inward-swinging sash.
In turn mode, yes — the sash swings into the room. Plan around curtains, blinds and anything sitting on the sill. In tilt mode it intrudes only 100–150mm at the top.
Usually yes. Fully turned, a standard tilt & turn easily exceeds the 0.33m² clear opening and 450mm minimum dimensions required by Part B for an escape window.
