UX 300e price subject to change?

I was looking at the UX 300e as a possible option a few weeks back or so and don't remember seeing this on the site:

Pricing and specifications shown are for model year 2022 UK vehicles, and subject to vehicle production lead times, the model ordered may be built according to model year 2023 specification, that may result in a different price. It is anticipated that your Lexus Centre will advise you of the exact On The Road price once your ordered vehicle goes into production (at the latest), at which point you have the right to accept such changes, or cancel your order and have any deposit returned to you.

What exactly does this mean and how much of a difference will the cost be? They start at £42,645 but if this price goes up because of what is outlined, it puts it out of range for me.
