Dont forget you can really only have a charger if you have private parking. I had a huge row with BP at one point as they claimed my driveway wasn’t private because I didn’t have a gate, my drive is in my back garden accessible from residents only road but there you go.
If you can’t have a charger there’s always a granny charger and extension lead (rated of course) that’s better than nothing. If you don’t take the charger you do get the BP Pulse 12 month subscription reducing the price of most of their chargers. As I already had a charger I took that this time, haven’t used it yet as I charge at home mostly and otherwise I use Electroverse and try to use Ionity chargers during the 20% off window which makes the rapids down to 63p/kwh which still expensive is nearly half what Instavolt charge.
I would consider your annual mileage, how much of that might be long journeys away from home as those would be on rapids potentially anyway. Then calculate how often you’d need to charge each week. Another option is some places have cheaper 7kw destination chargers if there’s one of those near home you could plug in and leave it there overnight. This is what I do when In Derby the airbnb has 7kw chargers walking distance from the house so I park there overnight and pay a fraction of the rapid rate at under 50p/kwh.
Also it will depend on the car range one with a range of say 150 miles is going to need more care than say an Enyaq with 300 mile range yet often both will charge at similar times due to charge rates on larger batteries.
I would see if a dealer will give you a weekend test drive and find out for yourself Good luck
