If you normally need about 12 kWh per day, then the £1000 upgrade will pay for itself in about 1 year and 3–4 months.
⚠️ But if you always use the full 6 hours at 7 kW (42 kWh), then you don’t actually save money—you just use more energy at nearly the same cost.

Do you usually charge your car fully for 6 hours every day, or just enough to get ~12 kWh? That changes whether this investment pays off.

After that, you’ll save roughly £500 per year on charging costs.
