Best EV Energy Tariffs in the UK (2025): Cut Charging Costs at Home

As more drivers in the UK switch to electric vehicles (EVs), the next big decision is how to charge them cheaply and efficiently. That’s where EV-specific energy tariffs come in.

Whether you’re a new EV owner or looking to switch suppliers, the right EV tariff can save you hundreds of pounds a year by offering cheaper overnight electricity rates and faster home charging.

In this guide, we’ll break down how EV tariffs work, who they’re for, and which suppliers offer the best deals in 2025 — so you can drive greener and spend less.

Quick Comparison: EV Tariffs at a Glance

Supplier	Off-Peak Rate	Off-Peak Hours	Smart Charger Needed?
Octopus Go	7.5p/kWh	12:30am–4:30am	No (recommended)
OVO Anytime	7p/kWh	Variable (AI-based)	Yes
British Gas	8.5p/kWh	12am–5am	No
E.ON Next	9p/kWh	12am–6am	No

What Is an EV Tariff?

An EV tariff is a specialist electricity deal that offers cheaper rates at night, when energy demand is low — perfect for charging your car while you sleep.

Most EV tariffs include:

• Off-peak pricing (e.g. 7.5p/kWh between 12am–5am)
  
• Two or more unit rates (off-peak and standard)
  
• Compatibility with smart meters, home EV chargers and battery storage units.
  

Some tariffs even link with specific chargers or car brands to automatically schedule your charging for the cheapest times.

How Much Can You Save?

Let’s break it down. If you were to remain on a ‘Standard Variable’ tariff, which has a single rate set at 26.4p per kilowatt hour (kWh), in accordance with the Energy Price Cap set by the energy regulator Ofgem as of 1st October 2025, the cost to charge a 60kWh EV battery would be £15.84. However, if you charged using an EV tariff, offering off-peak unit rates of 7.5p per kilowatt hour (kWh), the cost would be £4.50. This offers a saving of £11.34 per charge. If you average 10,000 miles per year, with a 60kWh battery, you would be charging the vehicle around 33 times a year making an annual saving of around £374.22. 

Scenario: Home charging on a standard tariff vs EV tariff

Tariff Type	Rate	Cost to Charge 60kWh
Standard Electricity Tariff	~26.4p/kWh	£15.84
EV Tariff (off-peak)	~7.5p/kWh	£4.50
Saving	~18.9p/kWh	£11.34

If you add in a battery storage unit, the savings keep on growing.

The average UK home, excluding charging an EV, uses around 2,700kWh per year which is around 7kWh per day. Using 2,700kWh on a ‘Standard Variable’ tariff at 26.4p per/kWh would cost £712.80 per year. Using 2,700kwh from a pre-charged battery storage unit at 7.5p per/kWh would cost £202.50 saving a further £510.30.

When Should You Switch?

With energy prices set to increase by a further 2% from 1st October 2025, now is a good time to review your energy usage and consider switching if:

• You’ve just bought an EV
  
• Your current tariff is a standard variable tariff
  
• You already charge at home and have a smart meter
  
• You have installed a battery storage unit
  

NOTE: Ensure you have a smart meter installed, as most EV tariffs require half-hourly data.

Do I Need a Smart Charger?

Most EV tariffs work best with a smart charger. This allows you to:

• Set timers to charge during off-peak hours
  
• Track usage in real-time
  
• Use apps (like Octopus or OVO) to automate charging when it’s cheapest
  

What Else Should You Look For?

When choosing an EV tariff, consider:

• Off-peak hours – Are they long enough for your charging needs?
  
• Standing charge – Some EV tariffs have higher daily standing charges which is the fee charged per day whether any energy is used or not
  
• Your overall usage – If you use lots of daytime power, higher peak rates might reduce savings

Export tariffs – If you also have solar panels, look for suppliers with good Smart Export Guarantee (SEG) rates
