It depends where you charge and at what speed. Get yourself Bonnet and Zapmap apps on your phone you can use these to find chargers, speed and price per kWh,
Typically the faster the charger the more per kWh they cost.
Some chargers are a rip off and I can easily see that cost happening but you are getting almost petrol range from the Enyaq and that is still cheaper than petrol and diesel.
For example Instavolt nearby cost 75p/kwh at 100kw
Gridserve 69p/kwh at 350kw
Podpoint 50p/kwh at 50kw
Podpoint at Tesco 44p/kWh at 7kw
I’ve seen the price as low as 25p/kWh at 7kw locally. There are still a few free ones at 7kw too most have some kind of condition attached.
It’s a case of like petrol understand what you’re paying per unit and only charge what you realistically need on more expensive chargers to get you going
