E (Gas and Electricity)

E (Gas and Electricity) is a British supplier of household electricity and gas.

Its offering centers on residential tariffs for homes with prepayment meters: the official switching page says a property must already have a prepayment meter to receive service. Under this model, customers manage the meter balance and can add credit through the MySmartE app, the online payment site, or the company's supported channels.

The MySmartE app lets customers check a smart meter and add credit from home or on the go. The company explains that reviewing usage over time can help customers see when they use more energy and where they might change habits; the meter provides information, while savings depend on household consumption and choices.

Support is available by phone, web form, and email. E publishes its switching process, frequently asked questions, and an explanation of the fuel mix behind the electricity it supplies.

The company also publishes information about the Warm Home Discount for customers who meet the applicable requirements. Its mailing address is listed in Birmingham alongside customer-support contact details.

The help page also explains how a switch begins: E sends a welcome pack and, for prepayment meters, the new keys and cards as applicable. Supply management then combines the meter balance with app and other top-up channels, while the fuel-mix page lets customers review how supplied electricity is generated.

For a household that already has a prepayment meter, the key points to compare are the quoted tariff, top-up options, and meter terms. E combines domestic energy supply with self-service tools, emergency credit, and phone support.
