I’ve been quoted £7,200 for a SigEnergy 9kWh battery and 10kWh inverter and £9,200 for a 15kWh battery and 10kWh inverter from Heatable. My questions are:

- does this price look reasonable?
- any other reputable suppliers/installers that I should check out?
- they quoted me an additional £500 to rewire my EV charger onto a submain to stop the battery discharging into the car. Surely this is a) way too much? and b) unnecessary (as EV only charges when the battery would be scheduled to charge).
- any other considerations I need for 3-phase supply?
