A charging session can cost £6 at home, £36 on a motorway rapid charger, or disappear into a prepaid network balance. The VAT reclaim on EV charging is not decided by the number on the app. It depends on the underlying supply, who bought it, whether you are VAT registered and how much of the electricity supported genuine business travel.
That distinction matters because an EV can produce excellent headline running costs while leaving a poor audit trail. A bank transaction proves that money left your account. It does not, by itself, prove the VAT rate, the supplier, the vehicle, the kWh bought or the business purpose. For a defensible claim, those details need to meet in one record.
VAT reclaim on EV charging starts with the supply
A VAT-registered business can normally recover input VAT on costs incurred for its taxable business activities. Electricity is no exception. But charging is less straightforward than filling a diesel van because the person paying, the person receiving the electricity and the business using the vehicle are often different.
Public charging is the cleanest case. If your business pays for a charge used for business travel, retain the charging receipt or VAT invoice, record the date, location, kWh, gross amount and VAT shown, then connect it to the journey or vehicle. Since 1 April 2026, public EV charging has been subject to the reduced 5% VAT rate, matching domestic electricity. Do not assume every historic receipt carries that rate, though. The tax point on older sessions may fall under the previous treatment, so use the VAT actually shown on the supplier’s document.
A payment card statement or charging-app history is useful supporting evidence, but it is not always enough on its own. Download the network receipt where possible. If a provider issues monthly invoices, retain those too, particularly where a number of drivers or vehicles sit under one account.
Home charging needs more care. The electricity supply is commonly in the driver’s personal name, even where a company car is charged on the drive. A limited company cannot automatically recover VAT from an employee’s or director’s domestic electricity bill merely because it reimburses some of the cost. The company has not necessarily received the supply for VAT purposes.
For a sole trader, the position can be different because the individual and business are the same legal person. Even then, only the business element is relevant. A sensible calculation needs the home tariff, the charge’s kWh and a credible split between business and private driving. A monthly household bill alone is too broad to show what the car actually used.
Start with business use, not the VAT amount
The recoverable amount follows business use. A car used solely for business journeys creates the simplest record. Most real EVs are mixed-use vehicles, however: client visits on Tuesday, school collection on Wednesday, a family weekend away on Saturday.
You need a repeatable way to separate those journeys. Mileage records are usually the foundation. Record the start and end readings or distance, journey purpose and vehicle. Pair that with charging records. You do not need to pretend every electron travelled to one destination, but your overall approach should make commercial sense.
For example, a consultant logs 1,200 miles in a month, of which 780 are client visits. Their charging ledger shows 320 kWh bought across home and public sessions. If the 65% business-mileage proportion is representative of the vehicle’s use, it may support an apportioned cost calculation. But it is not a substitute for evidence where a particular public charge was clearly for a private holiday or a business trip. Keep direct evidence where it exists and use an apportionment method consistently for the remainder.
There are two broad ways businesses commonly deal with mixed use: restrict input tax recovery to the business share from the outset, or recover VAT and account for private use where the rules allow. Which is suitable depends on the business structure, the vehicle arrangement and your wider VAT accounting. This is an area worth agreeing with your accountant rather than selecting the method that produces the largest number this quarter.
The same discipline applies to charging subscriptions, connection fees and prepaid credit. A £100 top-up is not automatically a £100 charging expense for the month. Record the amount paid, VAT, balance bought and kWh or cash balance remaining. Otherwise your accounts can overstate costs and reclaim VAT before the underlying service has been used.
Home, public and workplace charging are different records
The location changes the evidence you need, not just the price per kWh.
At home, log the charge from the vehicle or charger where possible: kWh added, tariff rate, date and the car involved. Include standing charges only if your accountant agrees they are a relevant, apportioned business cost. The electricity bill should remain on file, but the charge-level record is what turns a household utility bill into a usable vehicle-cost calculation.
At public chargers, preserve the supplier receipt. Network apps can revise their displays, accounts can close and payment references are rarely descriptive. A receipt captured when you unplug is far more useful than trying to rebuild a charging session from a bank statement six months later.
At a workplace, the VAT position depends on who supplies the electricity and on the arrangements for employees, directors, visitors and any private use. A company paying its own electricity bill has a clearer starting point than a company reimbursing someone else’s bill, but private charging still has to be dealt with properly. Do not treat a workplace charger as a blank cheque simply because it sits outside the office.
Mileage reimbursement is not the same as a VAT claim
Businesses often reimburse employees for business miles in their own EV. That can be a practical way to cover running costs, but the payment does not automatically create recoverable VAT.
The VAT treatment of mileage payments has its own conditions, including evidence of the underlying electricity cost and a clear business-mileage record. HMRC advisory rates can help set a reimbursement amount, but they are not a receipt and do not, by themselves, prove input tax. The same caution applies when a director pays personally then claims expenses from their company.
Keep the policy simple enough that people will follow it one-handed, in the dark, beside a charger: retain the receipt, log the journey, identify whether it was business or private, and submit the expense promptly. If staff use several networks, make the required fields the same for every charge.
Build a record that can survive questions later
A good EV VAT record is not a folder full of screenshots. It is a chain from supply to payment to vehicle to business purpose. For each charging cost, capture the supplier, date, location, kWh, gross amount, VAT rate and VAT amount. Add the registration number or vehicle, the driver where relevant, and enough mileage detail to explain business use.
Receipts should be readable and retained alongside the transaction. Where an invoice covers multiple charging sessions, preserve the invoice and the session-level export. Where one charging account serves several vehicles, allocate each session rather than spreading the bill evenly at month end.
This also improves your management figures. You can see the true blended cost per kWh, distinguish cheap overnight home charging from expensive en-route charging, and calculate cost per mile from actual use. More importantly, you can keep tax reporting separate from promotional EV savings claims. A low advertised tariff is not your real cost if most of your miles come from rapid charging.
Amperlo is built around that practical ledger: charge data, receipts, mileage, VAT splits and running costs in one place. The aim is not to make an EV look cheaper on paper. It is to show what your car actually costs to run, with enough evidence to support the numbers.
Common mistakes that weaken a claim
The recurring problems are usually mundane. Drivers claim the VAT shown in an app without saving the invoice. Businesses reclaim all electricity for a mixed-use car. Prepaid charging credit is treated as consumed energy. Home charging is reimbursed without considering who received the electricity supply. Mileage logs are completed retrospectively from memory.
None of these errors necessarily means the business has acted dishonestly. They do mean the calculation is hard to defend. Correcting it later takes longer than logging the charge when it happens.
VAT rules and HMRC guidance can change, and the right treatment depends on facts such as your VAT status, business structure, vehicle ownership and reimbursement policy. Use your accountant or tax adviser for a decision on your arrangement, especially where home charging or employee expenses are involved.
The useful habit is to treat every charge as a financial record at the moment it happens. Capture the receipt, kWh, VAT and journey context before you drive away. Your future self, and anyone reviewing the claim, will have real numbers rather than a reconstruction.
