I switched to Brit Gas Economy 7 (dual-rate) tariff in Feb 2021. When Covid19 restrictions were lifted, I booked the smart meter install prompted by a text message. The engineer came today and was about to install a "single-rate" smart meter. I politely declined the install when he explained that my tariff would change as a result of the install. When I phoned the contact centre, they said I'm not getting any benefits from dual-rate electricty and that I will be fine with the single rate tariff but she wouldn’t get me any new figures when I said "prove it". She said that the smart meter team dont do the calculations, so she had to pass me to the Tariff team. The agent on the Tariff team said my kWh charges would go from: Day: 16.862p/kWh ; and Night: 11.279p/kWh To a single flat rate of: 23.860p/kWh !! Now, I'm no maths whiz, but that is NOT the same or cheaper!! British Gas are operating like a bunch of scammers. A Smart Meter should not involve a tariff change. If it does - customers should be told very very clearly. Treating Customers Fairly ? I don’t think so :-(
