If you run a business in the UK and you provide cars to employees (or use company cars yourself), you might have come across the term “Fuel Scale Charges” (sometimes called the “road fuel scale charge”).
It’s a concept that often causes confusion. but it doesn’t need to be complex.
When fuel is paid for by a business and the company car is also used for private driving, HMRC sees a private benefit. That means tax and VAT rules join the party.
To avoid having to record every personal mile driven, businesses can use something called Fuel Scale Charges.

What Are The Fuel Scale Charges?
The fuel scale charge is a way for HMRC to account for private use of fuel in a business vehicle. If your company pays for fuel and the car is used for personal trips, this charge helps you pay the right amount of VAT.
It’s not a fine or penalty. It’s more like a flat-rate adjustment. Instead of tracking every personal mile, you use a set figure based on your car’s CO₂ emissions.
When Does The Fuel Scale Charge Apply?
The fuel scale charges apply to VAT-registered businesses that meet two specific conditions:
- The business provides road fuel for company cars.
- The business allows employees or directors to use these company cars for private mileage.
In short, If your business pays for fuel and the vehicle is used privately, then your business pays the fuel scale charge.
It applies whether you’re a sole trader, limited company, or partnership. If you reclaim VAT on fuel, you need to account for private use. That’s where this charge comes in.
VAT and the Fuel Scale Charge: How Does It Work?
Here is how you account for fuel scale charges VAT:
1. Reclaim VAT on all company fuel
2. Apply fuel scale charge as output VAT
3. Include it on your VAT return:
- Box 1: Output VAT
- Box 6: Value included as sales
The simple calculation idea is that you reclaim VAT on fuel but repay HMRC a fixed portion to cover private travel.
When Do Fuel Scale Charges Not Apply?
You may avoid the fuel scale charge if:
- There is no private use of the car at all
- You choose to reclaim VAT only on business miles
- The vehicle is a pool car with limited personal access
- You use a system where employees fully reimburse private fuel
- VAT is not reclaimed on fuel purchases
Also: Fuel scale charges do not normally apply to fully electric company cars because electricity is not classed as fuel.
How Does The Fuel Scale Charges Work In Practice?
Here is a simplified summary of steps, followed by some specifics.
Step-by-step:
- Identify the car: Confirm the car is VAT-registered via your business and is available for both business and private use.
- Check the CO₂ emissions figure: You’ll need the car’s CO₂ emissions (in g/km) from the vehicle registration certificate (V5C) or manufacturer documentation. For older cars without a figure you use a default engine size band.
- Find the right “scale charge” value: HMRC publishes tables of charges by CO₂ band and by your VAT accounting period length (monthly, quarterly or annually). Use the table which applies from the date your VAT period starts.
- Claim input VAT on fuel: You reclaim the VAT you paid on your fuel purchases (assuming you’re allowed to) as usual.
- Add the VAT to your output tax: On the same VAT return, enter the VAT amount of the fuel scale charge into Box 1 (VAT due on sales).
- Adjust your net sales: Enter the VAT-exclusive amount (the “net” figure) of the fuel scale charge into Box 6 (total value of sales and all other outputs).
- Use correct period and rates: If your VAT accounting period straddles the date when new rates apply, you must check whether you apply the old rate or the new rate. Typically the rule is: if your VAT accounting period begins on or after the date of change, you use the new rate. Also, businesses must use the same accounting method for all company cars. It is not possible to use the fuel scale charge for some vehicles and detailed mileage records for others.
What Are VAT Road Fuel Scale Charges From 1 May 2025?
From 1 May 2025 to 30 April 2026, HMRC released new fuel scale charge tables. If your VAT accounting period begins on or after 1 May 2025, you must use the new 2025/26 rates.
If your period starts before 1 May but ends after, you use the old rates for that period and switch to new rates in the next period.
Fuel Scale Charge Rates for 2025/2026
The new road VAT fuel scale charges apply from your first VAT accounting period beginning on or after 1 May 2025 and are valid until 30 April 2026.
Here are some key examples of the valuation table published by HMRC for the 2025/26 period:
| CO₂ emissions band | 12-month rate (VAT inclusive) | 3-month rate | 1-month rate |
|---|---|---|---|
| 120 g/km or less | £661.00 | £164.00 | £54.00 |
| 125 g/km | £990.00 | £248.00 | £82.00 |
| 130 g/km | £1,059.00 | £263.00 | £87.00 |
| 135 g/km | £1,122.00 | £280.00 | £93.00 |
Please check HMRC’s full table (for each emissions band) as this is only a short excerpt.
Note: Because these charges include VAT, when you account you might need to split out the VAT portion accordingly for your VAT return.
Why Does HMRC Use Fuel Scale Charges?
Tracking every journey is a pain. HMRC knows that. So instead of asking businesses to log every personal trip, they offer a simpler way.
You pay a fixed amount of VAT based on your car’s emissions and your VAT accounting period. It’s easier and avoids messy paperwork.
What Are The Advantages And Disadvantages Of Fuel Scale Charges?
Advantages Of Fuel Scale Charges
- Less record-keeping: If you opt for this method, there’s no need to track every single private journey’s fuel and business use ratio.
- Clear-cut compliance: By using HMRC published table you reduce risk of under accounting for private fuel VAT.
- Works well if private use is significant: If the car is used a lot for private journeys, this flat rate might mirror (or exceed) what you’d otherwise calculate
Disadvantages Of Fuel Scale Charges
- Potential cost: If you don’t use your company car for private use much, the flat fee might be more expensive than just claiming for your business miles.
- Requires application to all mixed-use cars: You can’t pick and choose. If you go with the flat-rate charge for one car that’s used for both business and personal travel, you have to use it for all of them.
- Accuracy required: You still need to make sure you use the right numbers for your car’s CO₂ emissions and accounting periods. Mistakes invite HMRC scrutiny.
Should Your Business Use The Fuel Scale Charge?
It depends on how you use your vehicles.
Use the fuel scale charge if:
- You pay for all fuel and reclaim VAT
- The vehicle is used for personal trips
Don’t use it if:
- You don’t reclaim VAT on fuel
- You keep detailed mileage records and only reclaim VAT on business use
Some businesses prefer to avoid the fuel scale charge by using mileage logs and advisory fuel rates.

How to Avoid the Fuel Scale Charge?
Businesses that supply fuel for private use in company cars have three main options for avoiding fuel scale charges:
- Keep detailed mileage records: Track business and private mileage separately. This allows you to reclaim VAT only on the business portion. This requires more admin work but can be more efficient if private use is minimal.
- Do not reclaim any VAT on fuel: Choose not to claim any VAT on fuel purchases. This simplifies compliance. But it may result in the highest tax cost for the business.
- Make employees pay for personal fuel: Another way to completely avoid the fuel scale charge is to have your employees pay you back for all the fuel they use for personal journeys. This removes the “benefit” they receive, so you don’t have to deal with the scale charge at all.
What Vehicles Does The Fuel Scale Charge Apply To?
The fuel scale charge applies to company cars that are made available for private use and for which the company provides fuel. The charge is based on the car’s CO2 emissions, with HMRC publishing annual tables of the charges.
Do Fuel Scale Charges Apply To Commercial Vehicles?
No, the fuel scale charge does not apply to commercial vehicles, such as vans, lorries, and other vehicles primarily designed for carrying goods. The fuel scale charge is specifically for company cars that are available for private use.
Do Fuel Scale Charges Apply To Electric Cars?
No, electricity is not considered “road fuel” for the purpose of this charge, so the fuel scale charge does not apply to fully electric company cars. The VAT treatment for reclaiming costs associated with charging an electric vehicle is different and depends on where the car is charged.
Does The Fuel Scale Charge Apply To Vans?
No, the fuel scale charge does not apply to vans or other commercial vehicles. If a van has more than “insignificant” private use, a business must make a reasonable estimate of the proportion of fuel used privately and restrict the input tax reclaimed on fuel accordingly.
Do Fuel Scale Charges Apply To Pool Cars?
No, a genuine “pool car” is exempt from the fuel scale charge. For a car to qualify as a pool car, it must meet strict HMRC conditions, including that it is:
- Used by more than one employee
- Not ordinarily kept overnight at or near an employee’s home
- Used only for business purposes, with any private use being merely incidental
Does The Fuel Charge Apply To Older Cars Without A Co2 Emissions Figure?
Yes, older cars without a CO2 emissions figure are still subject to a fuel charge, which is calculated based on their engine size. This applies to both Vehicle Excise Duty (road tax) and VAT fuel scale charges.
Does The Charge Apply To Bi-Fuel Cars?
For bi-fuel vehicles that have two CO2 emissions figures, you use the lower of the two figures to determine the fuel scale charge.
What Else Should You Watch Out For?
CO₂ Emissions Figure – Get It Right
- For newer cars you’ll find a CO₂ emissions figure (in grams per km) on the registration certificate. If it’s a dual-fuel car, you must use the lower of the two CO₂ figures.
- For cars registered before 1997 (which may not have a CO₂ figure) you’ll use the engine size method: up to 1,400 cc = use emissions band 140; over 1,400 but less than 2,000 = 175; over 2,000 = 225 or more.
- Round down emissions to the nearest multiple of 5 g/km if needed.
VAT Accounting Period Length Matters
The scale charge differs if your VAT return is monthly, quarterly or annually. Make sure you pick the correct column in the table (1-month, 3-month, 12-month).
Electric Company Cars: Special Rules
Electric company cars benefit from special treatment: the provision of electricity for private use in a fully electric company car is not treated as fuel for the Fuel Scale Charge. That means if you provide charging (home or at work) for private use on a fully electric company car, you may avoid this particular scale charge.
Avoid Mixing Methods
If you go for the Fuel Scale Charge method for your fleet (i.e., cars with mixed use), you cannot mix that method for one vehicle and detailed mileage method for another. Whichever method you choose must apply uniformly for all relevant vehicles.
Where The Business Buys, Reimburses Or Allows Fuel
Even if the business reimburses an employee for fuel used privately in a company car, the “private fuel benefit” rules may apply. The Fuel Scale Charge method is one way of managing that.
Common Mistakes
- Using outdated rates: Always check the latest table (for 1 May 2025 to 30 April 2026) if your period starts on/after 1 May 2025.
- Picking the wrong CO₂ band or failing to use the lower figure for dual-fuel cars.
- Applying wrong period rates (for example using the annual rate when you have a quarterly accounting period).
- Forgetting to include the scale charge in box 1 and box 6 of the VAT return.
- Not excluding genuine “business-only” cars or “pool cars” that have no meaningful private use, which might disqualify the scale method.
- Assuming the Fuel Scale Charge is the same as the “fuel benefit charge” for company cars. They are related but separate.
What’s the Difference Between Fuel Scale Charge and Fuel Benefit Charge?
The Fuel Benefit Charge is about income tax and National Insurance. If an employer provides fuel for an employee’s private use in a company car, that’s a benefit-in-kind (BIK) and the employee pays tax accordingly, and the employer pays Class 1A NICs.
The Fuel Scale Charge is a VAT matter: a way for the business to account for the VAT on the fuel used privately. These two are separate but often get mentioned together when companies provide cars + fuel.
So you might have both issues to handle: one for income tax/benefit, one for VAT.

The Bottom Line
The Fuel Scale Charge is a simplified method for VAT-registered businesses in the UK that provide fuel for cars which have mixed business and private use. It allows the business to reclaim input VAT on all fuel, but you pay a flat-rate “scale charge” for the private-use portion instead of tracking every mile.
From 1 May 2025 the updated tables apply. Use them if your VAT period starts on/after that date. You still need to check the vehicle’s CO₂ emissions, pick the correct rate for your accounting period length, and apply it in the correct boxes on the VAT return.
Always keep supporting documentation (fuel receipts, vehicle info, records of method chosen) in case HMRC asks.
