There's some important features worth considering.
The most basic is a dumb charger, you plug it in, it charges.
The next level up is one that supports timed charging to take advantage of economy 7 or Octopus Go tariffs or even solar production.
The clever ones will sync with the variable tariffs like Octopus Agile to charge when electricity is at its cheapest..
There's also different charging speeds, the X5 looks to only support 3.7kw charging so no major issues here for you. Most single phase chargers do upto 7kw. You can get faster but most houses only have single phase.
You'll want to see if you're eligible for a subsidised installation.
