Hi, I received varying quotes ranging from £400 for an exchange and fitting, to around £550–£650 for a full retrim of existing headliner. Since mine has a sunroof, it might be slightly more expensive. There was also a DIY option available at £200, which includes supply replacement (returning your old existing headliner) and fit it yourself. It’s on my to do list to finalise which option to run with. Hope that helps.
