I got a service plan with my last two leases and I think it was a complete waste of money. Nothing seems to be covered on it, and when you use them to come and pick you up when you've burst a tyre on a pothole they still charge £500!
It seems like on a brand new car, all the things the service...
Looked at it for a while, and ended up going for a Polestar instead. Do that, you won't regret it!
I used these guys and they were pretty good https://www.vehiclecontracts.co.uk/
