How the Energy Price Cap Affects EV Charging Costs

The energy price cap, decided by Ofgem, controls the electricity prices for homes on standard variable tariffs. This affects how much it costs to charge electric vehicles (EVs) at home. Generally, charging at home is cheaper than using public charging stations. However, rising energy costs mean that EV owners should pick the right EV energy tariff. This choice can help them save more money.

How the Energy Price Cap Impacts Home EV Charging Costs

Charging an electric car at home is a smart way to save on electricity costs, especially for those who can use off-peak rates. However, the price cap is impacting electricity prices. Because of this, many EV users are now dealing with higher costs per kWh.

Note: Costs exclude standing charges and VAT.

• EV owners using a regular tariff will spend over £14 for a full charge.
• Fixed tariffs can help save some money, but they don’t provide much flexibility.
• Special EV tariffs can reduce charging costs by more than 50% when using off-peak hours and rates from energy suppliers.

Public EV Charging Costs vs Home Charging

Public EV charging is more expensive than charging at home. This is even more noticeable with fast and ultra-fast chargers. Some energy suppliers offer lower prices for home charging. But, public EV drivers usually have to pay as they go.

Average UK Public EV Charging Costs (January 2025)

Charging at home is 50-70% cheaper than using public chargers. Ultra-rapid chargers can be almost four times more expensive than the lower rates for EVs during off-peak times. EV drivers should use apps like Zap-Map to compare prices for public charging. This way, they can find the best deals.

Best EV Chargers for Home Charging & Their Features

Choosing the right EV charger is important. It can change how quickly you charge your vehicle. It can also influence how much energy you consume. Plus, it matters if it fits with your electricity plans.

• Smart chargers can decide to charge when electricity is cheaper. This helps you save money.
• Solar-compatible chargers, like Zappi, can connect to solar panels. This allows for free energy for EVs.
• Using Direct Debit for EV energy tariffs often means you get lower rates.

EV-Specific Tariffs: How to Reduce Charging Costs

Many energy suppliers offer special deals for electric car drivers. These deals provide lower rates at night, which is off-peak hours, to help you save money. You can charge your electric car more cheaply when there is less demand on the grid.

Best EV Charging Tariffs in the UK (2025)

Octopus Energy and E.ON Next offer the lowest prices for charging electric vehicles (EV). To enjoy rates for EVs, you must have smart meters. Though the standing charges can be higher, the savings on off-peak electricity prices can make up for it.

How Smart Meters & Peak Times Impact EV Charging Costs

Using a smart meter can help EV drivers take advantage of EV energy tariffs in several ways:

• You can see how much electricity you are using right now.
• You can plan your charging for times when it is cheaper. This can help you save on energy costs during peak hours.

Peak vs Off-Peak Charging Cost Comparison

Charging an EV during peak hours costs over three times more than charging during off-peak hours. Smart chargers like Hive EV Charging and Zoom EV can automatically control charging. They do this at times when the rates are cheaper.

EV Charging Costs vs Petrol & Diesel Vehicles

As electricity prices increase due to the price cap, some drivers may question if electric vehicles (EVs) are still less expensive than petrol or diesel cars.

EV vs Petrol vs Diesel: Cost Per Mile (2025)

Charging EVs at home is still 4 to 6 times cheaper for each mile than using petrol or diesel cars. EV drivers who rely on public chargers may end up paying a cost per mile similar to diesel motorists. Finding cheaper options for EV charging can help save a lot compared to fossil fuel vehicles.

How Much Electricity Does an EV Use Compared to Household Appliances?

Many EV owners want to find out how charging at home compares to using regular appliances. If you understand energy use, you can decide the best time to charge your EV. This can help you save on energy bills.

• Electric vehicles (EVs) need more energy than all main appliances combined. Still, EV tariffs can greatly reduce expenses.
• A Hive EV Charger or other smart chargers can help use energy when demand is low. This results in cheaper rates during peak times.

EV Car Hire & Subscription Models: Are They Worth It?

Many drivers are considering subscription options instead of buying an EV. They are interested in services like Zoom EV or a year subscription for car hire.

• EV subscriptions include insurance, vehicle service, and often discounts for charging.
• New EV drivers may find it useful to rent an EV for a short time before choosing to buy one.
• Public charging can be cheaper for those who use an EV subscription.

How Energy Price Cap Changes Impact Fleet EV Charging Costs

The energy price cap helps keep electricity prices steady for homes. However, business fleets and EV drivers often pay more. This is because they use public chargers. When charging at home, people can save money by using lower rates during off-peak times. On the other hand, fleet vehicles often rely on rapid chargers. These prices do not have the same protections from the energy price cap.

How Much Do Fleet EVs Pay for Charging?

Company fleets that charge at public chargers spend much more on electricity than those with their own EV charging stations at work. Fleet operators can benefit from corporate EV pricing, which offers lower rates during off-peak times, similar to home charging. Businesses can save money by installing solar panels at their depots. This allows them to use free renewable energy to power their fleet EVs.

Fleet EVs vs Diesel Vehicles: Running Cost Comparison

• Electric vehicles (EVs) with fast chargers cost more to drive per mile than diesel cars do.
• Companies need to invest in chargers at work. This could help them save as much as charging EVs at home.
• Business energy rates may change in the future. This could help fleets save money when the grid is less busy.

How Solar Panels Can Reduce EV Charging Costs Under the Price Cap

With energy bills rising, many EV owners are installing solar panels on their homes. This allows them to save money on charging their EVs. By generating their own power, homes can dodge high peak prices and charge their EVs for free.

How Much Can Solar Panels Save on EV Charging?

• Solar panels along with a home battery can make charging EVs free.
• The Hive EV Charger and Zappi chargers allow you to use solar power to charge your EV. This means you will need less energy from the grid.
• Any extra solar energy can go back to the grid. This can help you earn kWh credit, which may reduce your other energy bills.

Best Solar EV Chargers in the UK

• Solar-friendly chargers allow you to charge your car using energy from the sun. This helps you rely less on grid electricity.
• With an online platform like ZapMap, EV drivers can look up the cost per kWh and make better home charging plans.

What the Future Holds for EV Charging Costs & Energy Tariffs

Many EV drivers are wondering if the costs of charging their electric vehicles will be cheaper or more expensive in the future. This curiosity comes as the energy price cap is rising.

• Last year, several energy suppliers stopped providing special rates for EVs. Some began using pricing models that change.
• From October 2024 to January 2025, off-peak EV tariffs are expected to be cheaper than regular rates.
• The next drive in EV pricing will focus on real-time pricing. This means EV owners can charge their cars according to current grid demand.

Future Predictions for EV Charging Costs

By 2030, charging your electric vehicle (EV) at home should be cheaper than it is today. New energy tariffs will reward EV owners who charge their cars during times when demand is low or when there is extra renewable energy on the grid. Smart chargers and energy storage will also help keep the costs of EV charging down.

Will the UK Introduce More EV Tariffs?

Ofgem is exploring new pricing plans just for electric vehicles (EVs). These will replace the old standard rates. They may use dynamic tariffs more frequently. These tariffs offer lower prices during times of low demand. Companies like Volvo and Zoom EV already offer yearly subscriptions that include discounts for public EV charging.

Final Thoughts

Charging your electric vehicle (EV) at home is the most affordable option. However, using public chargers can be quite expensive. The increase in the energy price cap has made it pricier to charge at home, but EV tariffs still provide better rates. Smart meters and off-peak tariffs are helpful for EV owners to save more on their electricity bills.
