Thanks for all your replies. Yes, those ace chips not cracks (although some are only chipped glass, some are small cracks – 4-5mm diam).
It’s not for the Omega, unfortunately I had to sell it, it’s for my Focus (I am a responsible father now, so have to think about fuel efficiency and costs

).
I had my Omega screen chipped and it was done with £15 excess by AutoWindscreen – they did a very good job. My insurance company only deals with AutoGlass and AutoWindscreen directly so that I only have to pay £15. I had to choose but found many complains about AutoGlass and saw what they did with a friend screen so decided to go for AutoWindscreen and it was really quick and high quality – my wife could not find it.
I am only concern if my insurance will ask me to pay £15 for each chip (x5 chips) in Focus, or will they replace the windscreen. I even don’t know if a heated screen can be repaired as it requires drilling which might damage the wire.
As far as I remember, insurance policy includes windscreen replacement to original quality, thus if it was fitted with this type, it should be replaced with one. That’s why there’s always a question if the car was modified in any way and if not, they will only cover what’s standard.
