Just to add, Autoglass contacted me again today to say that they can now do the calibration at one of their workshops, there was a list of about 10. I'm already booked into West Drayton so they will pick up the tab there.
For anyone else getting a replacement it might be worth probing a bit more, if there is a convenient location to you I bet they can replace the glass and calibrate at the same time.
