"For optimum charging at home, you can install a recommended Jaguar wall box1. I-PACE is equipped with a 7kW single phase AC on-board charger2, which can fully recharge the vehicle overnight and deliver up to 35km (22 miles) of range per hour. When using a domestic socket, charging rates are slower than a wall box (up to 11km of range per hour), but are sufficient to cover the average daily commute of 60km (38 miles) if the vehicle is charged overnight."æ
"The home charging cable enables you to charge the vehicle using a domestic power socket. Ask your Jaguar Retailer for more information on using I-PACE in other countries."

They use the word "wall box", however this term does not turn up many results in a search. It would seem that Jaguar does not have their own charger, and that they recommend others.
There is a company called "wallbox" and since the OP said single phase, 7kw, maybe they have something like this
Pulsar Plus Type 2 5m 7.4kW
I'm guessing that it is hardwired.
Additionally,
One thing that you will clearly notice about these units is that they separate the charging cord and wall-box (or socket). What this means is that the max current will possibly be limited both by the cable as well as the wall-box.
So maybe there is some need to check whether the cable that plugs into the wall-box can deliver 7kw.
Maybe the 7kw cable was sold with the Jaguar and the Tesla provided a lesser cable with similar ports (NOTE: I've got no idea about these cables).
This is different from North America where the home charging stations do not have removable cables, and in the cases where a socket is installed, we still have an electronic charging box with non-removable cable in between the socket and the car.
