Which Energy Company Has the Best EV App, Smart Charging & Customer Service in the UK?

For most UK EV drivers in 2026, Octopus Energy offers the best overall smart charging experience, while EDF, British Gas, and OVO suit specific charging habits.

The right supplier depends on when you charge, how automated you want it, and how much flexibility you need.

What Actually Matters for EV Tariffs in 2026

When choosing an EV-friendly energy supplier, four things matter most:

• Cheap off-peak rates (usually 7p–10p per kWh)

• Smart charging automation (charges when electricity is cheapest)

• A clear, easy-to-use app

• Reliable customer service if something goes wrong

If a supplier fails on one of these, savings and experience suffer.
