I have had a major issue with the charger failing to operate during overnight hours. The App is set to 1.15-6.15am. The charger ignores this! Beware, if you want to use cheap rate electricity perhaps look elsewhere. BP have had this issue "in hand" since March of this year when my new electric car arrived. Their resolution to date has been silence, ignoring emails for weeks, such a long wait time on calls in to customer service, that you give up after 60 minutes plus on hold! The only thing they have been able to suggest during the time is that we fit a manual old-fashioned timer to the charge unit! The App they provide does not seem to cut the charge off when it should, with instant charge on cable connection to the car being how it works. So far this has cost me several hundred pounds extra in day time charge rates, instead of significantly cheaper overnight rates. BP simply cannot be bothered. In hindsight I should have paid for a decent charging company with an after sales team that cares, rather than accept the "free" BP option that came with my car. Unfortunately there is no option to put Zero Stars in the review
