2026-27 VAT Fuel Scale Charges: Key Changes and What They Mean for Your Business

Published by Farazia Gillani posted in Automotive and Transportation, Value Added Tax (VAT), VAT on 5 May 2026

From 1 May 2026, the UK VAT road fuel scale charges change to cover the period to 30 April 2027. These flat-rate charges apply when a business reclaims VAT on vehicle fuel but a car is used for private travel. In practice, instead of keeping detailed mileage logs, a fixed scale charge is added to the VAT return to account for the private fuel usage. The new charges (VAT-inclusive) are set by CO₂ emission band and by the length of the VAT accounting period (1, 3 or 12 months). Businesses must start using the updated scales in the first VAT period beginning on or after 1 May 2026.

What is a fuel scale charge?

A fuel scale charge is effectively a fixed amount of output VAT owed per car, depending on CO₂ emissions. For example, a car emitting 140 g/km CO₂ has a charge of £98 for a one-month period (or £1,182 for a 12-month period). These values include VAT, so the VAT element is already built into the published figures. Typical 2026/27 charges include:

CO₂ (g/km)	12-month charge (£)	3-month charge (£)	1-month charge (£)
120 or less	657.00	163.00	54.00
140	1,182.00	294.00	98.00
180	1,708.00	426.00	142.00
225 or more	2,297.00	574.00	190.00

Key Changes for 2026–27 VAT Road Fuel Scale Charges

The 2026–27 rates are slightly lower than in 2025–26, following official adjustments. For instance, the top band (225+ g/km) charge fell from £2,314 to £2,297 per year, and the lowest band (≤120 g/km) fell from £661 to £657 per year. All businesses using the fuel scale must switch to these new figures for any VAT period starting 1 May 2026 or later. The published guidance makes clear that “the VAT road fuel scale charges are amended with effect from 1 May 2026” and must be used from that date onwards.

How to Calculate Your Fuel Scale Charge

Identify the car’s CO₂ emission band

Check the official CO₂ figure from the vehicle logbook, the DVLA database, or the manufacturer’s certificate. If the exact figure isn’t a multiple of 5 g, round it down to the nearest 5 (e.g. 143 g becomes 140 g). If the vehicle has more than one CO₂ figure (e.g. separate figures for petrol and hybrid modes), use the lowest or the combined rating as advised.

Special case – older cars:

Cars registered before 1997 may lack a CO₂ figure. In that case, use engine size to pick a band: up to 1,400 cc = 140 g/km band; 1,401–1,999 cc = 175 g/km band; 2,000 cc or more = 225 g/km band.

Choose period and charge:

Determine your VAT accounting period (1, 3 or 12 months). Then look up the corresponding charge for your CO₂ band. For example, a car at 125 g/km is in the 125 band, giving a charge of £246 for 3 months or £81 for 1 month (see table above).

Pro-rate if needed:

If the vehicle was used privately for only part of the VAT period, pro‑rate the charge. Calculate the percentage of the period during which the car was used, and apply that to the scale charge. For example, if the accounting period is 12 months but the car was used only 6 months, a 50% adjustment applies. This approach is confirmed in the guidance: “record [the percentage] of the accounting period. Apply this percentage to each road fuel scale charge to get a total figure”.

Include on the VAT return

The fuel scale charge (which already contains VAT) is added to the VAT return as output tax owing on fuel. In other words, businesses reclaim input VAT on fuel normally, then add the flat scale charge to Box 1 of the VAT return for the period.

Applying the Scale Charge

One driver per car:

The scale charge is applied per person-car combination. Each employee or director using a company car privately incurs one charge for that vehicle. If more than one person uses the same car, each must be treated separately.

Multiple cars:

If an individual has multiple cars, apply the same steps to each vehicle. If two cars happen to fall in the same CO₂ band for the same person, HMRC notes they “should be treated as if they were one car” when calculating percentages. In practice, this rarely affects the outcome compared to treating them separately.

Record-keeping:

Keep records of how each charge was calculated (CO₂ figure sources, period length, and any percentage used). This protects you in case of a VAT inspection.

Electric/hybrid vehicles:

A fully electric car does not use VATable fuel, so the fuel scale does not apply. For plug-in hybrids or conventional hybrids, use the petrol/diesel CO₂ band as above.

FAQs About Fuel Scale Charges in UK

Who must use fuel scale charges?

Any business that reclaims VAT on fuel for a car and allows private use must account for fuel. The fuel scale is a simple, blanket method, so many companies choose it instead of tracking actual miles. If no VAT was reclaimed on fuel, the scale charge is not needed.
