If you’re buying a new van in the UK, diesel is still the default for high mileage and heavy loads, electric is often the best choice for urban work and predictable routes, and petrol only really makes sense for light-duty, low-mileage use (and the limited models available). The “right” answer depends mainly on where you drive (ULEZ/CAZ), your daily miles, payload/towing needs, and whether you can charge reliably.

Diesel: best for long runs and heavy work

Modern Euro 6 diesel vans suit motorway miles, frequent long trips, and heavier payloads. They’re widely available with higher power outputs and are usually the simplest choice if you tow regularly. The trade-off is running in clean air zones: Euro 6 diesels are generally compliant, but rules and charges vary by city, so check your typical routes.

Petrol: niche option

Petrol vans are less common new, and tend to be smaller. They can suit low annual mileage, short trips, and lighter loads, but fuel economy is usually worse than diesel. If you’re considering petrol, double-check real-world mpg and resale prospects for that model.

Electric: ideal for cities and stop-start work

A new electric van can be excellent if you do, say, 50–150 miles a day, return to base, and can charge overnight. You’ll typically benefit from lower energy and servicing costs, and easy access to emissions zones. Upfront cost can be higher, but there is a Plug-in Van and Truck Grant (as currently published) of up to £2,500 for vans under 2,500kg GVW and up to £5,000 for vans up to 4,250kg GVW—grants are reviewed and can change, so confirm on Gov.uk/OZEV.

Two quick checks before you decide

1) Payload and range: EV range drops with weight, speed and winter heating; make sure your worst-day route fits with a buffer. 2) Charging: if you can’t install depot/home charging, public charging costs and downtime may erode the benefit.

Also budget for VED: for vans it’s a flat rate (currently £345/year) regardless of emissions, but always verify the latest rates.
