VAT on Fuel for UK Businesses

Petrol and diesel purchased for business use in the UK is subject to the standard 20% VAT rate. VAT-registered businesses can reclaim the VAT element on fuel costs — but the rules depend on how the fuel is used and how expenses are recorded. Getting this right is important for both your VAT return accuracy and HMRC compliance.

The Three Methods for Reclaiming Fuel VAT

HMRC allows three different methods for reclaiming VAT on fuel, depending on your business situation:

Method 1 — Reclaim All Fuel VAT (Business-Only Vehicles)

If a vehicle is used exclusively for business and is never used privately, you can reclaim all the VAT on fuel. This applies to commercial vehicles like vans, lorries, and taxis — and cars if you can demonstrate there is absolutely no private use (which is very difficult to prove for cars).

Method 2 — Reclaim VAT on Business Mileage Only

If a vehicle has both business and private use, you can reclaim VAT only on the fuel used for business journeys. You must keep a detailed mileage log showing business and private miles separately. Calculate the business proportion and apply it to the total fuel VAT.

Business Fuel VAT

VAT = Total fuel VAT × (Business miles ÷ Total miles)

e.g. £200 VAT × (8,000 ÷ 10,000) = £160

Extract VAT from fuel receipt

VAT = Fuel cost ÷ 6

e.g. £120 fuel ÷ 6 = £20 VAT

Method 3 — HMRC Fuel Scale Charge

If you reclaim all fuel VAT (including private use fuel) for convenience, HMRC requires you to add back a fuel scale charge — a fixed quarterly amount based on your vehicle's CO2 emissions. This simplifies record-keeping but can result in paying more VAT overall depending on your vehicle and mileage.

⛽ Worked Example — UK Sales Rep, Mixed Use Vehicle

Total fuel spend in quarter (gross, inc. VAT)£960.00
VAT on total fuel (÷ 6)£160.00
Business miles in quarter7,500
Total miles in quarter10,000
Business proportion (7,500 ÷ 10,000)75%
Reclaimable fuel VAT (£160 × 75%)£120.00

HMRC Advisory Mileage Rates for Fuel VAT

HMRC publishes Advisory Fuel Rates (AFRs) for company car users and Advisory Electric Rate (AER) for electric vehicles. These are used when employees are reimbursed for business mileage at the approved rate, or when calculating the VAT on fuel reimbursements.

Current HMRC AFRs (from 1 March 2025) for petrol-engined cars:

For hybrid cars, use the petrol or diesel rate. For electric company cars, the Advisory Electric Rate is 7p per mile. Check current rates at HMRC Advisory Fuel Rates (GOV.UK).

VAT on Employee Mileage Claims

When employees use their own car for business and are reimbursed at HMRC's approved mileage rates (45p per mile for first 10,000 miles, 25p thereafter), VAT-registered employers can reclaim the VAT element of the fuel portion of that mileage payment. The formula uses HMRC Advisory Fuel Rates to calculate the fuel cost component.

Important: You cannot reclaim VAT on fuel for private journeys. HMRC may check your fuel VAT claims during a VAT inspection, so accurate mileage records are essential. Keep fuel receipts for at least 6 years. Source: HMRC VAT on motoring expenses (GOV.UK)

Frequently Asked Questions — Fuel VAT UK

Can I reclaim VAT on fuel for my car?
It depends on how the car is used. If it is used exclusively for business (no private use — very difficult to prove for cars), you can reclaim all fuel VAT. If there is any private use, you can either reclaim only the business proportion (requiring mileage records) or reclaim all fuel VAT and pay a fuel scale charge to account for private use.
How much VAT is on fuel in the UK?
Fuel (petrol and diesel) is subject to the standard UK VAT rate of 20%. To find the VAT element in a fuel purchase, divide the total cost by 6. For example, a £72 fuel receipt includes £12 VAT (£72 ÷ 6 = £12) and £60 net fuel cost. Note that fuel duty is separate and cannot be reclaimed as VAT.
What records do I need to reclaim fuel VAT?
You need: VAT receipts for all fuel purchases (pump receipts showing VAT are sufficient for amounts under £250), a mileage log if reclaiming only on business miles, and records of your vehicle's CO2 emissions if using the fuel scale charge method. Keep all records for at least 6 years.
Can I reclaim VAT on fuel for a van or commercial vehicle?
Yes — VAT on fuel for a van or commercial vehicle used for business can be reclaimed in full if the vehicle is used only for business. If there is also private use, you should account for the private proportion. Commercial vehicles are treated differently from cars under HMRC rules — the restriction on cars does not apply to vans used for business.
