The “best” new van for refrigeration and chilled deliveries is the one that matches your payload, route length, temperature requirement and where you work (ULEZ/Clean Air Zones). In practice, most UK operators choose a medium panel van with a professionally integrated chiller, because it balances load space, running costs and availability of fridge conversions.
Start with your temperature and duty cycle
Chilled (typically 0–5°C) is much easier than frozen. If you’re doing multi-drop with lots of door openings, you’ll need stronger insulation and a higher-capacity unit than a single long run. Ask converters for a pull-down time and performance at summer ambient temps, not just a headline “to X°C”.
Payload and legal weights matter more than badge
Refrigeration adds weight (insulated lining, floor, bulkhead, unit, standby electrics). It’s common to lose a few hundred kilos of payload, so check the post-conversion plated payload in writing. If you’re regularly near the limit, consider a 3.5t van with a higher payload spec, or step up to a heavier GVW (note: above 3.5t can trigger different licensing and operator obligations depending on use).
Diesel, electric, or hybrid refrigeration?
Diesel vans are still the simplest for long distances and heavy loads, but make sure the base van is Euro 6/6d if you enter ULEZ/CAZ areas. Electric vans can be excellent for urban chilled work, but refrigeration draws extra energy, reducing range—get a real-world route trial with the fridge running. If you go electric, check eligibility for the Plug-in Van Grant (currently up to £2,500 under 2,500kg GVW or up to £5,000 up to 4,250kg GVW, but OZEV support can change—verify on Gov.uk).
Conversion quality is the deciding factor
Choose a converter that offers temperature mapping, HACCP-friendly finishes, warranty support and a clear plan for servicing. Also ask whether you need standby (mains) operation for depot loading and how it’s powered.
Two quick follow-ups to ask yourself: Do you need multi-temp (chilled + ambient/frozen zones), and will your insurer require a tracked temperature recorder? Both can change the ideal base van and budget.
