Car Tax by Weight UK 2026: Gross Vehicle Weight and VED

Car tax by weight UK — vehicle weight is a key factor in VED classification, especially for commercial vehicles. Here is how weight affects road tax in 2026.

Gross Vehicle Weight and VED

For standard cars and light goods vehicles, weight is not a direct factor in VED calculation — CO2 emissions determine the rate. However, weight does affect the vehicle's tax class. Vehicles with a gross vehicle weight (GVW) of 3,500kg or more are classified as heavy goods vehicles (HGVs) and pay different rates.

Light Goods Vehicles (Under 3,500kg GVW)

Vans and pickups with a GVW under 3,500kg are taxed as light goods vehicles. Most pay a flat £320/year rate regardless of CO2 emissions. Electric vans under 3,500kg pay £0 road tax — making them significantly cheaper to run than diesel equivalents.

Heavy Goods Vehicles (Over 3,500kg GVW)

Vehicles over 3,500kg GVW are classified as HGVs and pay a different annual VED structure. HGV road tax is higher and includes the Vehicle Exercise Duty supplement. Rates are based on weight bands and the number of axles. HGVs also face the HGV Road User Levy.

Payload and Classification

The payload (load-carrying capacity) of a vehicle determines its classification for some purposes. Pickups with a payload of 1,000kg or more are taxed as goods vehicles. Below this threshold, classification may be as a private car, which uses CO2-based VED.

Electric Van Weight Classifications

Electric vans often have a higher GVW than equivalent diesel vans due to battery weight. An electric van that exceeds 3,500kg GVW may be reclassified as an HGV, changing its VED band. Check the specific model's GVW with the manufacturer.

Conclusion

Car tax by weight UK: under 3,500kg GVW: flat £320/year for goods vehicles. Over 3,500kg: HGV VED rates. GOV.UK VED tables show full weight-based rates.
