I have noticed that my windscreen gets foggy. This never used to happen. A.C. does very little to fix it.

Is it possibly caused by the new non Lexus windscreen? How can I fix this as it affects driving at night time.

No, it won't be the new windscreen but quite possibly the way it has been fitted, that is, poorly...

Check the screen surrounds for gaps/dampness.

If it's very humid outside and the vents are pulling in the humid air then it condensates straight away on the cold windscreen....switch on fan boost and up the temp a little once screen is warmer you can back off with both boost and warmth...also worth recirculating cabin air until the car warms  the cabin air a little.  It happens to me very occasionally if I leave the car out for a long period on a misty muggy morning or evening.  I garage my car every night never left out in all the years I've had it since new...so once in a blue moon it might happen to me.  Leave A/C off until it settles as the cooling will only keep the screen cooler on the inside and again exacerbate the condensation effect.  If that doesn't cure it then as others have suggested you may well have a poorly fitted screen.  Now Autumn has arrived cooler and wetter...could be the reason. I think there's a smoke test than can be used to fill the cabin and see does it leak out with all vents closed.  Worth considering too that you may have a leak elsewhere bring moisture into the car and its staying there...worth checking for any damp carpet and any damaged rubber seals.

Was this fogging never used to happen, I'd double check the fitting of the new screen.

Having the a/c on permanently will help as the incoming air will be dehumidified.

Seals on cars, no matter how well built they are, will degrade over time allowing moisture in.
I suggest getting some drying bags to remove excess humidity. Running the aircon should quickly clear any mist on the inside as it's dry air.

Air con was not removing the mist. It reduced it.

Autoglass are coming to see it. What should I be aware of?

Not sure if you have same problem, but that was one of the signs before my A/C "died" - just need find leak and re-gas.

At first I realised it does not demist windshield even the air was relatively cold (I don't go crazy cold ~21.5C), stage 2 - it actually started misting windows even more, before actually stopped working altogether.
