What Happened
Fuel and energy costs are the single biggest pressure on UK fleet budgets, cited by more than half of operators, 51%, in new research from Webfleet, part of Bridgestone. Vehicle maintenance and downtime ranked second, named by almost a quarter of respondents at 24%. Export and Freight reported the findings on 26 August 2026. The research covers UK fleet operators rather than shipping lines, so it speaks to the road leg of an international movement, including collection, delivery and trunking between depots and ports.

How Fleet Fuel Costs Reach Your Road Freight Invoice
Road freight rates carry fuel as a variable element, not a fixed one. Most commercial vehicles in UK fleets run on diesel rather than petrol, but both track the same wholesale and duty movements, which is why a pump price change reaches a haulage invoice within weeks rather than months. Operators recover it through a fuel surcharge or a rate review at renewal. If you move FTL, LTL or groupage traffic on a standing rate, ask whether the surcharge is indexed to a published price or set at the operator’s discretion.
The finding sits inside a wider squeeze. Webfleet’s second-placed concern, vehicle maintenance and downtime at 24%, points to assets being held longer, which raises the risk of a vehicle failing on the day your consignment is booked. Energy costs now also cover depot electricity and charging for battery vehicles, so a fleet running a mixed diesel, petrol and electric profile carries several exposed price lines at once. For shippers, the practical consequence is less about pence per litre and more about how quickly a cost is passed through.
Ask for the fuel basis in writing before the next renewal, including the index used, the review frequency and the base price the surcharge is measured against. On cross-border road movements the haulage rate is only one part of the landed cost, because entry preparation, MRN issue and customs clearance services sit alongside it, and a hold at either border adds vehicle hours that higher petrol and diesel prices make more expensive. Where volumes allow, fixing a rate for a defined period moves the price risk to the operator, usually at a premium.
Key Takeaway for Shippers Buying Road Capacity
Fuel is now the line most likely to change your road freight cost between quote and invoice, on Webfleet’s evidence. Check the surcharge mechanism and the review date on every standing rate you hold, and treat a fixed all-in rate as a paid transfer of risk rather than a discount.
Market Impact for UK Importers and Exporters
Road haulage sits at both ends of almost every international consignment, so a cost pressure inside UK fleets reaches sea and air movements as well. Groupage traffic feels it first, because the fuel cost of a collection run is spread across a small number of consignments and a single price movement changes the per-pallet figure quickly. Full loads absorb it more evenly across the distance, but longer domestic legs from Avonmouth or Felixstowe to a Midlands or northern delivery point carry proportionally more exposure.
The maintenance and downtime figure matters for planning as much as for price. A vehicle off the road on the day of a booked collection pushes a container past its free time at the terminal, and quay rent and demurrage then attach to the shipment rather than to the haulier. Importers running just-in-time inbound flows should build a contingency window into arrival planning and confirm who bears the cost when a vehicle fails.
