I agree that fitting a larger battery capacity beyond the heating season tariff peak load shedding requirement will have a poor return on investment. Summer rates and consumption are low. Choosing the correct battery storage system for long life and safety is an important consideration too.
Trystan, I’ve just signed up to the new fixed tariff, when you have a minute could you please add INTELLI-FIX-12M-25-04-10
Thanks, John
