British Gas giving Octopus energy customers £46 off bill

British Gas is launching a special tariff for electric vehicle drivers and motorists who've got an eco-friendly car. British Gas, one of the largest suppliers in the country, has issued an alert to customers who can save cash with a new tariff.

"Charge smarter, pay less with our EV two-rate tariff. Get super-cheap electricity at night – just 7.9p per kWh between 12am-5am. Plus, we've lowered our day rate, so that's cheaper too. Win-win!" British Gas said on its website.

The off-peak rate is 7.9p per kWh and off-peak hours per week is 35 hours. The example cost at 3,900 kW of electricity is £966, down from Octopus' £1000, and the example cost at 5,000 kW of electricity is £1,201.52, when compared to Octopus' £1,242.

It said: "If you regularly charge your car during peak times or use significantly higher or lower amounts of electricity than the average EV owner, your actual yearly costs will be different to our estimates." It works for all EV drivers with any make of EV and with any home charger.

British Gas, which is run by Centrica, explained: "Our electric car energy tariff is a smart “two-rate tariff”, which charges different rates for peak and off-peak hours. Between 12am-5am every day you’ll get a super low off-peak price for electricity. That's 35 total off-peak hours every week to charge your car.

"We keep the daytime rate for our EV tariff as close as possible to our normal electricity rates, so you get great value." It’s available to all new and existing customers and you’ll need to have an electric vehicle you charge at home. We might ask you to prove this.

You'll need an electricity smart meter. If you don’t have an electricity smart meter, we’ll upgrade you to a smart meter, at no extra cost and you’ll have to pay by Direct Debit.
