UK Budget freezes fuel duty and boosts mileage relief for van fleets

The Autumn Budget 2026 extends fuel duty relief, holds HGV road tax unchanged and lifts mileage reimbursement rates, giving UK van and fleet operators near-term cost certainty through mid-2027. The package also keeps some support in place for electric van running costs as businesses prepare for tighter zero-emission rules.

Why it matters: - The Budget reduces near-term pressure on commercial vehicle operating costs at a time when many fleets are facing tight margins. - The measures give van operators, logistics firms and tradespeople more predictable fuel, tax and reimbursement costs through 1 July 2027. - The package also supports the economics of electric van use, which matters as fleets plan for future zero-emission requirements.

What happened: - The Chancellor of the Exchequer presented the Autumn Budget 2026 on 29 October 2026. - The government extended the 5p fuel duty cut and kept the wider fuel duty freeze in place until 1 July 2027. - Fuel duty stays at 52.95p per litre. - The HGV road tax holiday also remains in place until 1 July 2027. - The Budget made a permanent increase to statutory Approved Mileage Allowance Payment thresholds.

The details: - The fuel duty freeze keeps the rate at its lowest level in more than 16 years. - The red diesel rate remains at a two-decade low. - The fuel measures are designed to reduce sudden pump volatility in commercial budgets. - For distribution, service and delivery fleets, the freeze supports more accurate forecasting of haulage and logistics costs. - The AMAP rate is now permanently 55p per mile for the first 10,000 business miles. - The secondary AMAP threshold rises from 25p to 35p per mile. - The higher mileage rates are aimed at grey fleet operations, where employees or contractors use personal vehicles for business travel. - The change helps businesses reimburse staff for servicing, tyres and commercial motor insurance without creating extra tax burdens. - The government also extended the reduced VAT rate on domestic electricity until July 2027. - The Budget includes a commitment to decouple wholesale electricity prices from volatile gas markets. - For home-charging commercial van drivers, the VAT extension helps keep overnight charging costs lower.

Between the lines: - Commercial Vehicle Contracts views the Budget as short-term breathing space rather than a reason to slow fleet decarbonisation. - James Nixon said the tax freezes should be treated as “an operational bridge, not a permanent reprieve.” - The clearest message for fleet managers is that near-term cost relief does not remove the need to prepare for electrification. - Businesses that delay planning may face sharper pressure once policy deadlines tighten and energy reforms are still working through the system.

What's next: - Payroll and expense systems will need updating to reflect the new 55p and 35p mileage rates. - Fleet operators are likely to use the 18-month window to review route patterns, vehicle duty cycles and charging infrastructure. - Companies that balance diesel fleet efficiency with phased electric vehicle investment are likely to be better positioned on margins. - Longer-term fleet strategy will continue to be shaped by electricity pricing reform and zero-emission transport rules.

The bottom line: - The Budget buys UK van and fleet operators time, but not a reset. - Cost relief is immediate; electrification planning still needs to move forward.
