Retired,
Have you checked with your insurance company that they will be paying the full amount, including re-calibration?
From my experience when my windscreen cracked, I was only covered for the replacement windscreen, paying £75 excess only. However, if I wanted the lane departure warning re-aligned I would have had to pay the £1000 fee.
I am sure you have probably had confirmation but it would be horrible to find that out after.
Thanks for the concern / heads up!
Obtained a written quote from OPC detailing all parts, operations and costs. Emailed a copy to insurer (NFU) who OK'd it the same day.
I have to pay £75 for using my own repairer rather than £50 if I go with Autoglass who are NFU's preferred windscreen company.
