Road Legal Tow Bowser
Fully Compliant Tow Bowser for Transporting Fuel
Road legal tow bowsers are an ideal solution for transporting fuel to sites so that machinery and equipment can be kept operational in an efficient and convenient way. All our bowsers are designed and engineered to meet HSE standards on using a ‘wheeled trailer fitted with a tank’, European Directive 2007/46/EC and UN 1202 regulations on transporting diesel and gas oil.Whether you need to move diesel from larger fuel storage tanks to a remote site, or move between sites in order to refuel equipment, mobile bowsers have a range of incredibly useful applications. They can be used to transport fuel around a site, then attached to vehicles for transport elsewhere whenever required.
Ease Of Towing & Operation
Whichever tow bowser model you specify, you get a versatile refuelling system that's secure and stable while being towed or used. Our bowsers are also designed with an impressive ability to transport fuel across diverse surfaces whether you need to refuel machinery or plant on building sites, at events or within agricultural environments. Each towable fuel bowser incorporates operational components to transfer its contents safely and protect fuel dispensing equipment in a lockable cabinet.As well as fully road legible tow bowsers, we also supply an extensive range of fuel bowsers in a range of sizes including dispensing options and transportable tanks in plastic and steel.

What is a road-legal tow bowser, and who typically uses one?
A road-legal tow bowser is a trailer-mounted fuel or water tank that is type-approved or compliant with UK road traffic regulations, allowing it to be towed on public roads behind a suitable vehicle. They're most commonly used by farmers, groundskeepers, construction contractors, and plant hire operators who need to move diesel, water, or AdBlue between sites without arranging a separate tanker delivery.
Does a road-legal tow bowser need to be registered and have a number plate?
Yes, if you're towing it on a public road, the bowser trailer must be registered with the DVLA and display a number plate that matches the towing vehicle's registration. This is a legal requirement under UK road traffic legislation, not an optional extra.
What licence and towing capacity do I need to tow a diesel tow bowser on UK roads?
Your towing entitlement depends on your driving licence category and the bowser's maximum authorised mass (MAM). Most standard car licences (category B) allow towing up to 3,500 kg combined train weight, but a loaded diesel bowser can exceed this quickly. Check your V5C for your vehicle's maximum towing capacity and cross-reference the bowser's gross trailer weight before hitching up. If the combination exceeds your licence entitlement, you'll need a category B+E test.
How much diesel can a road-legal tow bowser carry?
Capacity varies significantly, from compact units for light-duty farm use to large-volume bowsers for fleet or site refuelling. The volume you can legally carry on the road is governed by ADR regulations, which set thresholds for specialist placarding, training, or documentation. For quantities below the ADR exemption threshold, requirements are considerably lighter.
Can I use a road-legal tow bowser to store diesel long-term, or is it just for transport?
Tow bowsers are primarily designed for transport and dispensing rather than long-term static storage. Keeping diesel in a mobile bowser for extended periods can introduce condensation and contamination, and a static installation would typically require a bunded tank to meet Environment Agency requirements. Using a dedicated static bunded tank for bulk storage and filling the bowser from it is the recommended approach.
Does a diesel tow bowser need a bund, and what are the environmental rules?
Mobile tow bowsers are not always double-skinned like static bunded tanks, but you are still legally responsible for any spillage under the Control of Pollution (Oil Storage) Regulations in England and equivalent devolved legislation. Many bowsers include an integral drip tray or self-bunding base. Refuelling near watercourses, drains, or environmentally sensitive land without adequate spill containment could result in significant Environment Agency enforcement action, so always carry appropriate spill kits.
What pump and dispensing equipment comes with a road-legal tow bowser?
This varies by model and supplier. Many bowsers come with a 12V or 24V electric pump, a dispensing hose, and a nozzle as standard, but some are sold as tank-only units. Confirm exactly what is included in the listed price, particularly the flow rate of any pump supplied, which matters if you're refuelling large plant machinery.
How do I maintain a diesel tow bowser to keep it roadworthy?
Regular maintenance covers the fuel system and the trailer itself. Inspect hoses, couplings, and the nozzle for wear or leaks before each use, and drain the pump if the bowser will sit unused through winter. For the trailer, check tyre pressures and condition, wheel bearings, the coupling head, breakaway cable, and lighting board connections before each road journey. Keep a record of inspections if the bowser is used commercially.
What is the typical lead time and delivery arrangement for a road-legal tow bowser?
Tow bowsers are delivered by specialist haulage rather than standard courier. Lead times depend on the model and current stock levels, so contact the supplier directly for a confirmed timeframe. Ensure you have suitable access for an articulated or flatbed delivery vehicle and enough space to offload safely, as kerbside delivery is standard and the driver may not be able to position the unit in its final location.
