How to Cut Fuel Costs for Your Work Van (2026)
Updated June 2026 · Estimates only — verify before quoting
For most UK tradesmen the work van is the second-biggest overhead after wages — and fuel is the single largest part of running it. A busy sole trader doing 20,000–30,000 miles a year can easily spend £3,000–£5,000 on diesel alone, so trimming even a few pence a litre and a few unnecessary miles adds up to real money over a year.
This guide covers the practical ways to cut van fuel costs in 2026, from finding the cheapest forecourt to smarter routing and driving — plus a free live fuel-price tracker so you never overpay at the pump.

Check live fuel prices near youAlways fill up at the cheapest local forecourt
Prices between forecourts just a mile apart can differ by 10p a litre or more. Supermarket sites (Asda, Tesco, Morrisons, Sainsbury’s) are almost always cheaper than branded or motorway forecourts. Checking live prices before you fill is the single easiest saving.

- Fill up before joining a motorway — service-station fuel is the dearest of all
- Top up in full rather than little-and-often to cut wasted trips
Cut the miles, not just the price
The cheapest litre is the one you never burn. Plan jobs by area so you are not crossing town twice, batch material runs, and use the quietest times to avoid idling in traffic. A well-planned week can knock 10–15% off your mileage.
Keep the van efficient
Under-inflated tyres, a roof rack left on, and a van full of kit you don’t need all raise consumption. Regular servicing, correct tyre pressures and stripping out dead weight can improve MPG by several percent for almost no cost.
- Check tyre pressures weekly
- Remove roof racks/ladders when not needed
- Service on schedule — a clogged filter costs MPG
Don’t forget the tax side
If you’re self-employed you can claim fuel and van running costs against tax — either as actual costs or via the simplified mileage rate. Keeping fuel receipts and mileage records means you claim every penny you’re entitled to. See our guide on claiming fuel and mileage below.
