Good Energy has launched the Smart EV Fixed Tariff (July 25), available from 1 July, which pairs a five-hour overnight charging rate with a free subscription to the Zapmap charging app1. The tariff will be live until 31 July 20251.
The overnight rate of 7.4p per kWh applies in a five-hour window between 12am and 5am1. Electricity used between 5am and 11:59pm is charged at a peak rate of 28.3p per kWh1. Good Energy says the off-peak rate means a standard range Tesla Model Y can be charged from empty to 100% for as little as £4.50, and that the tariff supplies 100% renewable electricity at home1.
The tariff includes a free Premium subscription to Zapmap, which usually costs £29.99 per year or £2.99 per month1. Premium adds Apple CarPlay and Android Auto, extra filters, unlimited saved routes in the app, and a 5% discount on charging paid for through the Zapmap app1. Good Energy is a long-term partner of and largest investor in Zapmap, which reports over 1.5 million downloads, more than 60,000 mapped charge points and over 75% providing live status updates1.
Nigel Pocklington, chief executive officer of Good Energy and chair of Zapmap, said:
"This new tariff, together with the excellent additional features from Zapmap, is designed to make it as cost effective and straightforward as possible to drive an electric vehicle."
Good Energy describes itself as a supplier of 100% renewable power, with long-term power purchase agreements with a community of more than 2,500 independent UK generators, and as the UK's largest voluntary administrator of the Feed-in-Tariff scheme1. It also offers solar and heat pump installations1. Zapmap was founded in 2014 and reports over 850,000 registered users1.
| Period | Rate |

| 12am to 5am | 7.4p per kWh |
| 5am to 11:59pm | 28.3p per kWh |
Why it matters for households
An overnight rate of 7.4p per kWh against a daytime rate of 28.3p per kWh makes the timing of home charging the main lever on running costs for a household on this tariff, and it puts the largest share of a home's electricity use onto the cheaper window only if consumption can be shifted there. The five-hour window is fixed, so the benefit depends on a car and a charger that can complete a charge in that period, and on other heavy loads, such as a heat pump or a washing machine, being run overnight rather than during the day. The tariff is fixed until 31 July 2025, which sets the period over which those rates are known. The bundled Zapmap Premium subscription covers public charging rather than home use, and its 5% discount applies only to charging paid for through the Zapmap app. Good Energy has not reported an exit fee, standing charge or any eligibility conditions for this tariff.
