Tesla UK lease question

[cb31]

I feel a bit stupid asking this but I've never done this kind of thing before and can't see an answer on the website. If I order a model 3 from the UK website, business rental for say 24 months, it says 6 months initial and around £500 per month. Is that 6*£500 plus 24 * £500, or 6 * £500 plus 18 * £500?

I have a virtual consultation booked for Thursday but if someone knows that would be very helpful, thanks
