EV Charging VAT: Why Home Charging Is Taxed Differently to Public Chargepoints
Domestic electricity, including for EV home charging, carries 5% VAT. Public chargepoint electricity is generally standard-rated at 20%. How the gap affects running costs, and what it means for employees reimbursed for charging.
The VAT gap that shapes EV running costs
If you've ever compared notes with another EV driver on how much they pay to charge, and found the numbers wildly different, VAT is part of the explanation β alongside the underlying electricity unit rate itself.
| Charging location | VAT rate | Why |
|---|---|---|
| Home (domestic supply) | 5% | Reduced rate for domestic fuel and power |
| Public chargepoint | 20% | Standard rate β treated as commercial supply |
| Workplace charging | Varies | Depends on arrangement β check current guidance |
Why home charging gets the reduced rate
The UK has long applied a reduced 5% VAT rate to domestic fuel and power β gas, electricity, and certain other household energy supplies to your own home. This reflects household energy as an essential cost, taxed more lightly than most other goods and services. When you charge an EV from your home electricity supply, that charging draws on the same domestic tariff, so it benefits from the same 5% rate as the rest of your household consumption β there is no separate metering or higher rate applied specifically to the portion used for car charging.
Why public charging doesn't qualify for the same relief
Public chargepoints are operated commercially β by dedicated charging networks, supermarkets, motorway service areas, or on-street council schemes. The electricity supplied through them is classified as a standard-rated commercial supply, attracting the full 20% VAT rate, because it doesn't meet the conditions for the domestic fuel and power relief (which is specifically tied to supplies to a person's own home).
This means the underlying electricity used to charge an EV can be taxed completely differently depending purely on where the charging happens β a quirk that predates EVs becoming mainstream and was originally designed around gas and electricity meters in people's homes, not car charging infrastructure.
The equity problem
This creates a genuine fairness issue that's been widely discussed in EV policy circles. Drivers with a driveway or garage, able to install a home chargepoint, typically:
- Pay the 5% VAT rate on their charging electricity.
- Often access cheaper overnight EV-specific electricity tariffs, further reducing the effective cost per mile.
Drivers without off-street parking β a significant proportion of UK households, especially in cities and terraced housing β typically must rely on public charging, and therefore:
- Pay the 20% VAT rate on their charging electricity.
- Often face higher underlying per-kWh rates charged by public network operators, on top of the VAT difference.
The combined effect is that some of the drivers least able to afford higher running costs end up paying meaningfully more to run an electric vehicle than those with home charging access β the opposite of what a policy encouraging EV adoption would ideally produce.

For a rough sense of scale: if home electricity costs around 25p/kWh (domestic rate including 5% VAT) and a public rapid chargepoint costs meaningfully more per kWh once its own commercial pricing and 20% VAT are factored in, the gap in cost-per-mile between a driveway charger and a public-charging-only driver can be substantial over a year of typical mileage β the exact figures depend heavily on your specific tariffs and the chargepoint network used, so it's worth comparing your own real bills rather than relying on generic averages.
What can reduce the gap
- Off-peak home tariffs β many suppliers offer dedicated EV or off-peak tariffs with much cheaper overnight rates, which combine with the 5% VAT rate to substantially lower cost per mile for home-charging drivers.
- Workplace charging β where offered, this can sometimes come with more favourable tax and cost treatment than public charging, depending on the specific arrangement with your employer.
- Comparing public network operators β per-kWh rates vary significantly between networks, so shopping around (rather than defaulting to the nearest chargepoint) can meaningfully affect your ongoing costs even though the 20% VAT rate itself won't change.
- Community and on-street charging schemes β some local authorities are rolling out lamppost or on-street chargers intended to be more accessible (and sometimes cheaper) for residents without driveways, though availability varies significantly by area.
The bottom line
The VAT treatment of EV charging is a structural, largely overlooked factor in the real-world cost of running an electric car β and one that currently favours drivers who can charge at home over those who can't. There is no confirmed change to equalise the rates as of the current tax year, so anyone weighing up the total cost of EV ownership without a driveway should factor the 20% public-charging VAT rate, and typically higher public unit rates, into their calculations rather than assuming EV running costs will automatically undercut petrol or diesel by the margin often quoted for home-charging drivers.
Frequently asked questions
What VAT rate applies to home EV charging?
Home EV charging uses your domestic electricity supply, which carries the reduced 5% VAT rate that applies to household energy generally β the same rate you pay on the rest of your home electricity bill, with no separate higher rate for the portion used to charge a car.
What VAT rate applies to public EV chargepoints?
Electricity supplied through public chargepoints is generally treated as a standard-rated supply at 20% VAT, since it is classified as being supplied for business/commercial use via the chargepoint operator rather than as domestic household energy, even though the end customer is an individual charging their own car.
Why is there a difference between home and public charging VAT rates?
The reduced 5% rate for domestic fuel and power is a long-standing VAT relief tied to supplies to a person's own home, reflecting energy as an essential household cost. Public chargepoint electricity doesn't meet the conditions for that domestic relief because it's supplied commercially at a public location, so the standard 20% rate applies instead β a distinction that predates widespread EV adoption and has been criticised as inconsistent for EV drivers without home charging access.
Does this mean people without a driveway or home charger pay more to run an EV?
Often, yes, in relative terms β someone reliant on public charging pays 20% VAT on the electricity itself, on top of the chargepoint operator's per-kWh rate (which is frequently already higher than typical domestic tariffs), while a driver who can charge at home pays only 5% VAT on a cheaper unit rate. This has been a recurring point in debates about the fairness of EV running costs for people without off-street parking.
Can employers reclaim VAT on EV charging provided to employees?
VAT recovery rules for business charging of employee-owned or company-owned EVs are detailed and depend on factors including who owns the vehicle, whether charging happens at the workplace, home, or public chargepoints, and how usage is apportioned between business and private mileage β this is a specialist area and employers should take specific advice rather than assume standard fuel VAT recovery rules apply unchanged.
Does salary sacrifice for an EV change the VAT treatment of charging?
Salary sacrifice arrangements primarily affect how the car itself is provided and taxed as a Benefit in Kind β they don't generally change the VAT rate applied to the electricity used to charge the car, which still depends on whether the charging happens at home (5%) or via a public/commercial chargepoint (20%).
Are there proposals to equalise the VAT rate between home and public charging?
This has been raised repeatedly by EV industry groups and consumer campaigners as an equity issue, but as of the current tax year no change has been confirmed β check current gov.uk and HMRC guidance for the latest position before assuming a change has taken effect.
Does workplace charging provided free by an employer have a VAT or tax implication?
Charging provided by an employer at the workplace for an employee's own electric vehicle has historically been treated as a tax-free benefit in many circumstances, separate from the VAT treatment of the electricity supply itself β check current HMRC guidance on employer-provided electricity for company cars and employee-owned vehicles, as the rules differ from those for fuel.
